Hi all, I have purchased T440 a month ago, I have no external battery, the laptop use to start normal booting windows 10 pro using the power adapter, it also works well using the internal battery but yesterday when I connected the power adapter it did not start, so IA had to reset it then tried it without adapter and is working well but as soon as I insert the adapter it stops work, also it does not charge the internal battery. Every time I connect the adapter it stop working and I need to reset it . I have checked the power adapter, it reads 20V d.c which is normal, I also tried another adapter kown good but the fault the same. Any help is much appreciated.

Running Windows 7 64-bit, I uninstalled all the battery and AC drivers in device manager, installed the latest Lenovo Power Management Driver and Software, ran the gauge reset option on the internal battery, and still never moves from 0%.  Brand new out of the box laptop.  I did finally get the external battery charging, but the internal one has never.  0 cycle count.  Any other options than returning this system?

Answer:T440 internal battery will not charge

Did you let the reset finish through the shutdown and restart?  Does the second battery show uo in device manager?

Hello all, I recently recieved my IdeaPad Y410p from the Lenovo repair centre and they changed my system board for a different issue, but now I have a new problem. I updated Windows to 8.1 and did all the critical updates and then tried to uninstall some of Lenovo's bloatware and now my laptop won't turn on or charge the battery. I tried to do a power drain (remove the battery and hold down the power button), but still no luck. The laptop won't turn on at all with the battery or the plug by itself.  I then waited a few hours and tried to turn on my laptop again and then this time it powered on for some reason! I quickly restored my system back to Windows 8 thinking there was a problem with an update or bloatware uninstallation and then all seemed well until  I powered down my laptop again, but then couldn't power it back on. I called Leneovo and they said it was impossible for it to be a hardware problem since they just repaired it and since I updated everything and then restored it back, which then it still had the same power issues means it most likely isn't software. The only other thing I could think of is there might be a problem with the power adapter, but I've had this laptop since July 2013 and the adapter was working perfectly fine and this problem only started once I received my laptop back from Lenovo after a "repair". Any other suggestions would be very much appreciated at this point. Thanks!

Answer:Lenovo IdeaPad Y410p won't power on with power adapter plugged in and won't charge battery.

Hi there -  I wanted to add that I am having the same problem. I sent my Lenovo in for warranty repair (rear left hinge broke) - I got it back Friday May 16th and ever since then it won't stay on and sometimes won't turn on. I called Lenovo warranty support and (of course) they denied it was their problem. However, I complained enough that they're going to send me a new one. Of course, you have to be in-warranty for this to work. Just a suggestion Hope you get your straightened out!!!

I have a Thinkpad t440s running windows 7. The internal battery won't charge beyond 80% and the removable battery won't charge at all.  I've read other threads here and have tried uninstalling the Microsoft ACPI-Compliant Control Method Battery using device manager but this has not fixed the issue. Any other ideas?

Answer:Thinkpad T440s internal battery won't charge beyond 80% and external battery won't charge at all

Hi Nicktr,
 
Welcome to Lenovo Community!
 
I think the problem you are running into is Power Manager conflicting with the 80% BIOS threshold. So to avoid this, either keeps the Power Manager threshold for both batteries below 80%, or else both batteries above 80%.
 
Hope this helps.

Iv recently encountered the dreaded Plugged-In not charging Error
Upon Boot
ALERT! AC power wattage and type cannot be determined. The battery may not charge. The system will adjust the performance to match the power available. 
Iv come to the conclusion its the module that determines the adapter and wattage type.
As iv tested it with known working chargers and batteries.
Can anyone *** me with this knowledge or allow me to get a schematic for the mother board?

After buying a T440 (not throuh lenovo), I realized that it has capability to hold an internal battery. But the item I bought didn't have one. Instead it came with a 6 cell external battery which protrudes in the back. Is there any way I can have internal battery added now? I see that some sites like Amazon are selling replacement internal batteries; can I buy it and install in my laptop? Thanks in advance for your replies!

Hello, just recently I'm a very happy owner of the yoga.I'm fine tuning the setup and tweaking all kind of things.With a different Lenovo I used in the past, I could use the power manager or the registry to specify a charge starting and ending point in percentages when hooking up the laptop to the main power, so it would for example charge to 80% instead of 100%. This was totally awesome to keep the battery healthy and keeping the Lenovo alive to the fullest.With the 720, I don't see the battery option anywhere. Things I tried are: -Registry edit-Installing system interface foundation-Installing power management from windows 7 or 8.1-Installing/reinstalling lenovo settings from windows store-Battery gauge tool install-Bios updates Unfortunately, they didn't work So my question is, has anyone set up the battery treshold on the Yoga 720. And how did you do it?Thanks for your answers!

Answer:Yoga 720 battery treshold set charge start stop power manager

Has nobody set up the battery treshold for charging?My first post was maybe confusing with the explanation of the different things I tried. Maybe in short my question is: when starting the 'Lenovo Settings', do the battery options show up, or did you have to do something special?

After my friend's laptop wouldn't run on battery power OR charge the battery I tried many "fixes."
 
Shockingly none worked that I found.
 
Only one thing worked for me to my surprise.
 
A last ditch effort was to open up the laptop (sony pcg-81114L) and disconnect the cmos battery for a few minutes to reset the CMOS.
 
To my surprise, when powered on, the battery instantly showed it was charging AND when removing the power plug the battery POWERS the laptop now! (and I'd thought I was wasting my time.)
 
Worked with an off brand battery also.
 
Many times this has saved many computers that have odd "unsolvable" things wrong with them.
 
Surely someone else has done this also but I haven't seen it posted anywhere to my knowledge.
 
Thank GOD for bringing the idea to remembrance!

 My battery will not charge, at all.  The guage was obviously not correct as it would drop very quickly after reaching 20% so I updated the Power Manager to 6.07 and then performed a battery reset (I am pretty sure it was in this order, may have been the reset first). After the reset the battery charged back up to 100% but as it discharged, the charger did not come back on.  With the power in, the battery just sits at the same percentage and very slowly goes down (~1% in two days).   I tried playing with the battery maintenance settings, the meter then says that charging will begin below 80% but the battery is already on 20%.  I checked the firmware in Power Manager and with the standalone program but apparently no update is needed and the part number FRU 42T4755 is not listed as needing an update. Current firmware version: 0004-3f98-0160-0130 I tried uninstalling and reinstalling Power Manager.  The windows power manager  also seems to have the same problem. I only baught the laptop last year, it is one month out of warranty; I need it to be portable for work.I thought about buying a new battery but it seems to be the charging function that is not working, and the battery was working fine before the reset and update, apart from losing some capacity and the inaccurate meter. Product: 0578CTO    Thinkpad Edge 14 Bios: 80ET61WW (2.01) Any help would be greatly appreciated.Nathan19% an...

Hey guys, hopefully you can help me out.

I suddenly lost all power to my AC adapter and thus ran out of battery power quickly. I desperately needed to use my computer and ended up going to BB and bought a new adapter for my Dell Inspiron 9200. It runs perfectly when plugged in, but now it will not recharge the battery. It turns off instantly when I unplug the cord.

Is my battery ruined too? Could it be caused by my AC adapter breaking? How can I tell it to start charging the battery, not just supply power directly?

Thanks,
Joe
 

Answer:Bought new AC adapter, Battery won't charge now

How long did you leave it for the battery to charge? Does the battery charing icon show up as charging in the bottom right hand toolbar?

Have you taken the battery out and checked all the contacts are clean and not bent out of shape? If they are not shiny, polish them with a pencil eraser.

Hi all,

Bit annoying this one...

The laptop will not run on AC power at all... but it will charge the battery while the laptop is switched off. If I remove the battery it will not work either so flashing the bios appears to be a fruitless task.

Any ideas what could be wrong? Some of my reading on this board suggests a motherboard fault but I bought this laptop as a reconditioned/end of line model from PC World and I am unsure exactly of my rights with this.

Any help is much appreciated.

Vaughan

Answer:Not working on AC Adapter but it will charge battery

Hi

The other people could be right. It looks like something wrong with the motherboard.
Possibly it?s a power supply electronic issue?. but this is just an assumption?

However, the solution is the same:
You need a hardware technician who would find out what part exactly malfunctions and would replace it?
I think in your case it?s a motherboard?

Hi All, I have a Thinkpad T520. It won't charge the battery (% charged stays at the same level) and it won't run from the battery only. If I turn off/remove AC power the computer dies immediately and it won't start up without the AC power plugged in. The battery is definitely good, it works in another computer. Is this a problem which I can fix myself? Can it be repaired? Will it be expensive? Will it require a new motherboard? It is not under warranty. Thanks, so much SV P.S. Any suggestions will need to be written in fairly simple terms, I'm no expert

Answer:Thinkpad T520 won't charge battery or run from battery power.

The problem is the charging circuit on the motherboard. It might be a fuse, but that is soldered to the motherboard, so unless you have a well-equipped repair place with a rework station (not a dealer) they cannot replace the fuse. If it isn't a fuse, it is probably a power transistor, and you are not likely to find someone to fix it. Probably, you will need a motherboard

I bought a refurbished T400 less than 3 months ago. Today the power status change beeps started going off every minute or so, the power indicator light went off (while plugged in) and the battery began discharging. At the same time, the screen started flickering. I powered down and tried draining the static by using the old trick: removing the battery and ac plug and pressing the start button 10 times and then holding on the 11th try. Didn't solve the problem. When I use battery only, the screen doesn't flicker. Plug in power and the screen starts flickering again, with the power LED mostly off but occasionally flickering on briefly.The battery is not listed as charging. Nothing to indicate that the power is plugged in, except for the occasional flash of the LED and the power status change beeps. When I power down again and stay plugged in both the power LED and the battery LED keep flashing. First both are flashing green, but in a few minutes the battery light turns flashing orange. If I remove the battery, both LEDs keep flashing. Try to power on that way and nothing happens - the LED's keep flashing, but it doesn't power on at all Battery is new (the first one shipped wouldn't hold a charge at all; this one lists as good condition). I don't have another Lenovo power supply to try, but the current one doesn't appear damaged or bent at all. I tried jiggling it while plugged in and there was no change. The last thing I did before the pr... Read more

Answer:T400 Power Problem: Flashing AC Power LED, No Battery Charge, Screen Flicker, No AC Boot

It sounds like either the ac adapter is sick (most likely) or the jack is bad.  If the power supply doesn't have "Lenovo" moulded into the plastic, it is probably a knock-off, and they use crummy wires between the transformer and the round plug.  This is a common probem for fake adapters

Basically I have a very specialized ruggedized laptop(Endura Notino R5500), it was fine until it would only charge if I put its adapter in an awkward position. I sent it in for repairs(under warranty) and all they did was cut of the end of my adapter and I suspect probably solder a new end on (even though my adapter is not under warranty and they were supposed to look for internal problems).It was O.K but the same problem came back after 2 weeks with the 'new' adapter (which was clearly my old one)and before I sent it off again I ordered a new adapter and battery, just in case it might have been both that were at fault and put them into the laptop, it still has the same problem.
I thought this may be a power jack/motherboard problem afterwards because it still only has power in the most ridiculous awkward positions,but,whereas before it actually charged when put into this position now it is not even charging, both my old absolutely fine battery/and new battery. I wonder whether it may be some tricky virus as well. However I don't think so as windows does not even have time to boot. It may also be a jack AND battery pin problem. It could be the case that I was at fault as the awkward position my adapter had to be in to charge (which basically involved tugging at the end of it) lead to internal damage.
The reason why I suspect a virus may also be at play is another laptop in my house has the same charging problem,but not the problem of the adapter having to be put in a specific... Read more

Answer:New Battery new adapter still won't charge. Might be multiple problems at once.

It sounds as though there is a problem with the DC socket on the mobo. Some of these are easy to change as they are connected by a mini harness. Others are trickier (ie, more expensive) as they are soldered in. The problem with the other laptop is unrelated, and I've never come across a virus that can have any effect on the charging circuitry.

Hello to the Thinkpad forum!I bought my R31 just over two years ago, and it's given excellent service. However, lately it's showing its age. Here are the problems: The AC adapter is really fishy these days. The power connector now wobbles when it's in the AC port; I don't remember that happening before. As a result of this loose connection, I have to fiddle with the cord to get the computer to run off AC power, and to make matters worse, for the past week, it charges the battery unpredictably. A few days ago, the battery power monitor stayed stuck at X%, no matter how long I had it plugged in. Three days ago, it was charging normally. For the past few days, it's not charging the battery again. I'm down to 6%, and I'm starting to get really concerned that I won't be able to take it with me anymore.What can I do about this? Also, there's a weird problem I'm having, where the computer will sometimes freeze, and it will start going again if I press down on the flat part of the Thinkpad, west or south of the mouse buttons. Is there some type of safety switch that stops the processor unless the switch is depressed, and there's something wrong with the switch in mine? I would greatly appreciate any help; I'm planning to buy an R61i to replace this, but I'm trying to wait until my bank account looks a little better before I do, so I'm trying to keep this baby going, at least until I get the replacement.

Answer:R31 - AC adapter sometimes doesn't charge battery, a few other problems

Welcome to the forum! Probably the simplest (and most cost-efficient) solution to some of your problems would be to get a port replicator. These can be found for under $20 used. The last R31 that I've owned had some of the problems that you're referring to, and keeping it in one spot in the replicator kept it going. There's no switch that you're pressing in that area, you're probably touching a "cold" soldering point.  Your motherboard may be on its way out. Check the Outlet for inexpensive R6x machines... Hope this helps.

Hello,

any advice appreciated.

I have had a Satellite Pro L20 for about 18 months. Recently the battery does not charge when AC adapter is plugged in. The battery light starts off yellow (meaning over discharged, I think?), then goes to green once the machine has been on for a while. However ACPI often says AC is "offline".

There are two recent occurences that coincide with this problem, which I am attempting to eliminate:

1. My girlfriends pet rat chewed through the power cable! Power is getting to laptop OK insomuch as it runs off mains - the rat seems to have just chewed through the outer cover (I can see some wire, but I think that is just shielding, though I am not an electrician).

2. I put the laptop into hibernation for the first time. This seemed to mess up the system a bit, which was what initially alerted me to the problem. This matter is slightly complicated in that I am running Linux (Xubuntu).

I updated the drivers etc from windows when I bought the laptop. Never had any trouble up till now and have been running linux for ages. Also, I mainly power the laptop off mains, but do not remove the battery (is that really a problem these days?)

I will obviously need to replace the AC adaptor, but is it likely (and how can I check) that the battery has been borked in the meantime?

cheers
chris

Answer:Satellite Pro L20: battery does not charge when AC adapter is plugged in

First of all please check if the other LEDs are on.
If the AC led and the power led are on then the AC adaptor is ok and provides the power to the notebook.

>The battery light starts off yellow (meaning over discharged, I think?), then goes to green once the machine has been on for a while
If the battery LED is yellow, this means that the battery is not fully charged and if the led changes to green then the charging procedure is fished and the battery was recharged.

So I really don?t see any problems with the charging procedure.

Possibly the battery is old and therefore you cannot use it for a longer period? in such case only the battery replacement could helps.

The issue has been progressive over a few months. When the ac adapter is plugged into the laptop, the blue LED lights for a second then changes to amber. After a few seconds the LED goes off. On the screen the battery stsus icon will show the AC symbol while the LED is ON but it goes away whn the LED goes off. The battery does not charge. I have a new battery. I have another g6 laptop (uses the same battery) that i can charge the batteries in and the AC adapter works flawlessly in that laptop. After the LED goes out I have to remove the AC adapter plug from the laptop and wait a few minutes. Then when i plug the AC adapter plug back into the laptop power socket the cycle repeats; blue LED 1 seocnd, amber LED a few seconds, AC icon on battery status indicator,  LED off, AC icon disappears, battery does not charge. Two different AC adapters, two different batteries (one new and one older - both genuine hp batteries). If I leave the AC adapter plugged into the laptop the LED will not come back on and the AC icon never reappears. I must remove the AC plug from the laptop for a period of time to restart the cycle (short). When the issue started the cycle of charging was longer and it slowely over time has reduces to this few seconds. It seems maybe something in the charge circuit is overheating?

Im having an issue charging my laptop battery, i have tried a the fix where you uninstall the drivers from the device manager and  shut down the computer and boot back up but it wont do anything The computer will turn on with the AC adapter connected and the battery out.Computer will turn on with the Battery in and the AC adapter disconnected.Computer will turn on with the battery in. If the computer is turned off with the battery in and i plug in the AC adapter nothing happens it would not charge it.If the computer is off without the battery and I plug in the AC adapter the power light with the little lightning bolt will flash once and it would allow me to turn on the computer. So i dont know exactly whats going on. I tried to turn on the computer with the AC adapter only and windows shows it recognizes its connected, but if i plug in the battery it would automatically change from saying that is connected to disconnected and stars running with the battery juice only even when the AC is still connected. Some how i feel like the battery overrides the AC adapter and i dont know what to do... Please help

Hi All, I have been stymied by a problem with my S10e.  As background, I have a North American power configuration and have been using the laptop in Asia and now in the UK. My problems started when the power adapter failed while on a trip in Asia.  I took the laptop and power adapter to a local reseller who determined that the adapter still worked, however the physical connector at the end of the lead no longer worked and was unable to provide power.  To solve this issue, I purchased a new Universal Power adapter that can take a range of input and modulate output to work for my laptop.  This has worked successfully and I am running off of AC power now. Several weeks after the adapter problem, the battery started to die, with max capacity dropping from 98% to 70% to 44% to 10% and then to 0% over the course of a week.  This ultimately meant that I can only run on AC power as the battery is purely dead weight.   An interesting fact (that may be entirely useless), is that if I have power running to the adapter and then plug the adapter to my computer, I get a little spark.   Based on this, I plug the adapter into the computer first, then plug the adapter into AC power. I have looked at the forum archives and the only similar solution I have found is this:http://forums.lenovo.com/t5/IdeaPad-S-series-Netbooks/S9e-battery-pack-not-charging/m-p/138811#M4233 which I have tried several times to no avail.   Does...

Hi ,My name is Kyle and I'm 16 and have a Dell Inspiron 1545 Laptop that was bought roughly two years ago at Christmas time by my parents.  The laptop itself seems to be in pretty good condition, although a few months ago I had to replace the hard drive.  It runs on Windows 7, BIOS version A11, and has roughly 150 GB of free disk space.  I do not pay for security programs, although I do use Microsoft Security Essentials and Advanced SystemCare 4 to keep it running smoothly.The problem I'm having is that the laptop battery is not charging.  I have the AC adapter plugged in and the battery is in place but the battery icon on my laptop says "Plugged in, not charging."  The power level is at 0% because I drained the battery to see if it would fix the issue but it did not.  I have tried various methods found on multiple websites to fix this issue, but most of those methods were specifically geared for issues involving Windows Vista and did not fix my problem anyway.  Some of these methods include reseating the battery and adapter in numerous progressions along with shutting down and rebooting the laptop as well as disabling the Microsoft ACPI-Compliant Control Method Battery driver in my Device Manager and re-enabling it.  As I have said, none of these methods worked.  The adapter itself works because I have tried running my laptop solely on AC power with the battery not attached and it runs fine, and it also shows ...

Hello,

This is my first post here, I am hoping somebody can help me!
I have a Toshiba Satellite C855 1GQ laptop.

So, basically I managed to break the end of the original charger (the part which plugs into the laptop) and stupidly tried a similar fitting charger from another device which had a lower output than the Toshiba one,

however when I plugged it in it killed the laptop battery as well as the adapter (it was an old one anyway). I have a new battery and a new charger adapter but the battery will not charge.

When I first put the battery in it worked fine so the laptop itself is not broken, the laptop tells me that it is plugged in and charging but it just loses power until the battery goes flat.

The new charger adapter does not seem to work despite the fact that it tells me it is with a working battery. The specifications for the new adapter are the same as the original (I got a cheapish one from ebay).

Is there a fuse inside the laptop which may have blown when I stupidly used the adapter I shouldn't have? I have read a lot of possible solutions on this but none seem to be specific for my problem. Maybe the new adapter is not good enough?

Like I said, the new battery worked fine until it ran out of power so it must be the charger or something on the laptop stopping it from charging.
Any help would be much appreciated!

Cheers,
Chris D.

Answer:Satellite C855-1GQ: Battery does not charge - adapter is connected

> Is there a fuse inside the laptop which may have blown when I stupidly used the adapter I shouldn't have?

The usage of wrong and not compatible AC adapter will damage the notebook?s hardware (motherboard could be affected)
Very important is the fact that the original AC adapter supports the 19V (volt) output voltage and
3.42A (ampere) output current.

Usage of Ac adaptor with different output voltage (not 19V) would affect the hardware.
The usage of AC adaptor with 19V output voltage but different ampere value should not affect the hardware.

Furthermore low ampere value (< 3A) might not be good enough for battery charging?
But in case the AC adaptor is compatible, i would test definitely another, new, fully compatible battery.

Just faced a rather strange issue, but not really an issue, just different system behaviour than expected. System:W520 Batteries:55++ connected27++ connected Power adapter:Unplugged No other accessories connected. Scenario:I was using the system till it power itself off due to low power (0% reached for both batteries). i.e. Ungraceful Windows shutdown. Then upon pressing the power on button, the LEDs flashes, no THINKPAD logo or BIOS message appears, system appears to then restart again, and the LEDs flash again...and loops until it was no longer able to even attempt to POST. Expected behaviour:Either display the message that says "Battery level is too low".OrDon't loop (this is the behaviour when only the 55++ battery is connected at 0%) Why does having the 27++ would make the system go through this looping cycle?

Answer:W520, 55++, 27++, unplugged from power adapter, 0% battery. Press Power button --> power up loops.

Hello Chatbox,
 
I can understand your issue very well, as there is no message comes on the screen which gives you information to plug the power adapter and prevent the laptop to get shut down.
 
You should install Power Manager software and then customize it as per your requirement.
The software can be download from the mentioned below web link.
http://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles/8mu417ww.exe
 
 
Hope, after this laptop will not shut down automatically due to battery backup

Hello, I just noticed this problem last night.
Ive had this laptop for 2 years now, and no problems at all.
If i unplug my battery adapter from the laptop it will instantly die.
The laptop says that I have a 100% charged battery....
When I plug the battery adapter when the laptop is off, the indicator blinks red 3 times, and once white then nothing..
Ive searched the web, and updated my bios and quickset and nothing worked.
The recent bios was suppose to fix this problem but its still happening.

Any thoughts?? I went into my bios and it recognizes the battery but it wont charge...........

I also saw mention of an updated power adapter so it is possible that Dell shipped a batch of bad adapters.

On the BIOS screen the AC Adapter is shown as "Unknown" when it is the Dell supplied adapter (or a Dell purchased replacement).

No idea about the nuances of Power Bridge, but what about having the other battery attached?Some Acer machines have an external switch for the internal battery, so you could just handle it mechanically instead of convolutedly through software. You'd think Lenovo would have come up with something similarly flexible.

I currently have a XPS 12-9Q33 laptop that is not charging. The light at the end of the power adapter is no longer lighting up so it appears to be faulty. I've called Dell to purchase a new adapter but was told that they no longer sell replacements for them and was recommended to buy an adapter from a 3rd party source.
I purchased a replacement with the same voltage and amperage that is supposed to work on a XPS 12. The laptop now powers on but will not charge. The BIOS states that the adapter is unknown and will not allow it to charge.
What can I do now? I find it really frustrating that I cannot get a direct replacement from Dell themselves so I'm stuck with a laptop that is not portable at all since the battery is at 0%

I have an X220 (which is, hands-down, the best laptop I've ever owned). My wife recently bought a T530 for herself. The power adapters appear to be roughly the same, though the T530 has a significantly larger brick. Are the two adapters compatible, or if I find myself running low on power with only her adapter available would it fry my machine?













Solved!

Go to Solution.

Answer:Charge an X220 with the power adapter of a T530?

you can use a 65, 90 and 135 watts adapter with the X220. The T530 you got have a 90 watts adapter. The adapter is designed to only supply the current (voltage is fixed) and therefore the power only as needed by the machine. It is not constantly supplying 65, 90 or 135 watts, these are the rated maximum power.

THEN, I'll be able to charge the batter. Can anyone help because the phone support at Lenovo didn't understand the problem and send me a new battery. ALL my software is up today, BIOS updated, battery discharged 3 times....I even reimaged the hard drive...NOTHING!!!! HELP!! Please and thank you.

Yeah. I pressed the on-button (while sutdown) again and the indicator says 100% charged when OS restarted, but yet has no charge. I already changed the management software settings and windows settings with no avail I even uplugged everything and reset the on button for 5 seconds while the computer was shutdown, restarted, and for a few minutes it said "battery plugged in, but NOT charging". Fixed it to show  "charging" but i monitored my laptop and it went from 0% to 100% charge in a matter of 2minutes, but then again the battery has no charge. I am baffled by this. Turned computer off, unplugged the adpater, tried to turn it on without any avail even though my indicator said fully charge. What the hell is going on here?

i have a common problem that my laptop don t on or charge battery or switch on ac adapter by reading through the forum's  i can t find out what the problem would be so i can solve it ?

Answer:my laptop lenovo don t charge or load on ac power adapter

n1ghtwalk3r, Welcome to the forum.  What model system do you have? If you remove the battery, will it start up on AC?   I suggest you get a digital meter, set for 20V DC range and test the voltage coming out of adapter at the tip that would plug into the laptop.  This should help you figure out if the Adapter is working - it should be putting out 16V-20V. If not, replace it. If it works, and your system runs with the battery out, then I suggest your battery is bad and should be replaced. Best regards, Mark

Hi all,
There's a user who has a Latitude 7440 with Win 7 Pro. When she puts the laptop on the dock in the morning and turns it on, there's a message before Windows starts that says something like "The battery does not have enough charge to power the dock".
I checked the BIOS and it recognizes the 130w adaptor and you can see the charge level increase, it went from 20% to 23% while I was watching. I swapped out the dock and adaptor because I didn't know what else to do.
Can anyone explain what causes this or if there's a common fix? I told her to call me if it happens again and I'm not sure what the next step would be.
Thanks.

Answer:Battery does not have enough charge to power the dock?

Let's backup. The dock should have its own AC adapter and power cord and should not be using the AC adapter and power cord that shipped with the laptop. At the end of her workday, she should turn the laptop off (not any powersave modes), and plug it into its own AC adapter and power cord to charge overnight. Then when she docks, what happens?

Years back, being cheaper than external drives I had bought an internal drive as a backup. I also bought an USB to IDE/SATA kit in order to make the backup with. Well the kit seemed to be problematic and so I scrapped it and bought another one only to find the same problem.
it then occurred to me that perhaps the problem is that though the kit has a power supply the HD did not have power going to it--it only attached to the 2 SATA parts.
So I was wondering, how do I get power to it? What is the adapter for such a thing called and does it exist?
See attached photo to see my HD. The pins are not those fat ones but small ones

Answer:Internal HD power adapter for external use.

The two connectors on the right are power, far right , SATA, center.
The connector you have marked power is not power.

On some drives a connector for jumpers is in that position.

Hello Everyone, Yesterday morning, I ran Thinkvantage System Update and installed the new Power Manager (1.43) and Power Management Driver (1.50).  Since that time, the battery meter will only go down, not up.  I left my computer on last night connected to AC, and it was at 54% this morning, where it was yesterday.  I took it off for a while longer and it is now at 35%.  Plugged in, it will maintain its current level of charge.  Per Lenovo support instruction, I uninstalled first the Power Manager, rebooted and checked; then uninstalled the Power Management Driver, rebooted and checked; using the computer for a short while monitoring the charge via the Control Panel Power Options.  Nothing changed, and I reinstalled the updates, both manually with the executable files and again utilizing the Thinkvantage System Update.  I have checked the BIOS settings, changed the Power Manager settings (scheme, options, charge threshold, etcetera) and otherwise gone through all the usual hoops discoverable with Google to try to correct the problem. The machine is an X60 (1709-53U) running XP (fully updated, both with Windows and Thinkvantage) and the battery is almost brand new, replaced in July with a Lenovo factory battery. Indeed, it would seem I am stuck.  The latest Lenovo support agent told me there is no way to individually acquire an older version of the driver or software, and that I...

So I'm fixing (or trying to fix) a friends laptop. It's a HP Pavilion zv5120us. The problem is that when powered on, the laptop will not accept power from the AC adapter (which should be low voltage DC power when it get's to it right?). It will however charge the battery when the computer is shut off. So it will run till the battery is dead, then charge itself and then you can turn it on again.

Apparently the zv5000s have similar problems like, no battery charge, no power whatsoever and most of these problems originate from the AC jack. I HAVE ALREADY BOUGHT AND INSTALLED A NEW JACK. My soldering was top notch. The problem persists in exactly the same manner. I have also tested the AC adapter. It has a green LED that comes on and with a multimeter it registered something like 40.9 on the 200 setting for AC volts. All these things make me think it's some software problem. Maybe there's some stupid setting that got switched so it won't run off wall power.

If anything triggers a thought for anyone please reply, I want to get rid of this thing.

The original adapter cord for my T61 laptop shorted and sparked right at the base of the laptop connector where the cord had apparently cracked through from too much bending.  Then the laptop worked fine on the battery until it ran out of juice.  There is no indication of power to the laptop on the replacement power adapter cord though.  I verified power at the laptop end of the replacement cord with a multi meter. I think this pretty well isolates the problem to between where the cord plugs in and where the battery power joins the circuit, right?  Would that be in the power supply?  I've read that there is not a "power supply" per se in laptops but that it is integral with the fan kit.  So should I just be ordering a replacement "Thermal device and fan (Integrated)" to fix this problem?  I see in the part list that this is marked as "not to be replaced by the customer".  Is that just a warranty statement, irrelevant outside of warranty, or should I be looking for a good repair shop? I have some experience with computer repair, but have not dealt with any repair shops in years, and have never dug into a laptop myself.  What I think I know to this point, as stated above, is based on a bit of web searching and general experience.  In reality, I'm very unsure of anything I've said regarding diagnosis or next steps.  Please advise. Thank you, James

This means the battery needs to be replaced. You can get another one from Ebay, just type in your make and model# computer with the word Battery,

Hi, Error message is '(25% available, plugged in, not charging)'Have already tried the following:- Battery unistall/re-install- Removal of battery whilst power cable and laptop is booted and reinsert (numerous times!!) Charges for only 2-3 seconds then back to the error message again Laptop dies completely when power cable is removed or when laptop screen is closed down. I am reluctant to buy a  new battery in case it does not resolve the issue.  Computer is not that old and was rarely used until only recently.

Hi!  I have a Thinkpad T43 with the ATI graphics card.  It has worked greatup until a few days ago.  I was running off of the battery.  The battery needed to be charged, so I plugged in the laptop and noticed the battery light did not indicate charging, nor the power light come on. I then shut down and tried to boot directly from the A/C adapter.  No power lights were on, nor would not boot.  I tried booting from the battery and I was able to boot, but the battery promptly died.  I still could not get any power from the AC. I thought the adapter was bad, so I bought a new adapter.  I tried plugging in the new adapter, the battery charge light came on for a brief second, then went out and still no power lights or boot. I tried the tip with pushing the power button for 10 seconds, 10 consec. times but to no avail. Does anyone have any suggestions?Thanks

Answer:Battery Died, now no lights/power or wont charge

Hi Blair230,Sounds like the AC adapter connector on the laptop where the adapter's plug is inserted has gone bad. Motherboard would need to be replaced or fixed if it turns out to be the case.Hope it helps.

My A30p (2653-64U) usually lives in a 'type 2631' dock (the old kind w/ Ultrabay & PCI card slots). After a week's vacation away from the dock, I find that the A30p won't run from AC power when docked, the dock's power-button serves to turn the computer on, but the dock's power-supply fan doesn't start & the computer continues to run from its battery. When undocked, the A30p will run from both its battery & its AC adaptor, but won't re-charge the battery while running on AC - the tray indicator shows that it's charging the battery, but the charge-amount remains at 9%. What kind of troubleshooting / configuring do I need to do to solve these problems? 

Answer:A30p won't charge battery or accept AC power from dock

Welcome to the forum! Have you tried using another docking station with your A30p? Good luck and let us know.

Hello all,I've spent some time browsing and searching this forum to avoid asking a question that has already been answered but I haven't seen a complete answer to this situation so here goes. I have a Lenovo 3000 N100 model 0768DKU.  Battery (P/N 92P1185) started not charging/not holding a change about 6-8 months ago AND the laptop now abruptly shuts down even when on AC power.  From the forum I found out about the 18 month battery replacement policy but I'm just a few months past the 18 months so out of luck there.  Normally I would just buy a new battery but the last few months I've been getting very frequent shut downs when the laptop is exclusively on AC power even with the battery removed!  This has kept me from buying a battery because the laptop won't stay on even when it's plugged into the wall then how will a battery help?  This has really thrown me for a loop since the laptop may run 30 minutes then it's dead like you pulled the power cord.  Turn it back on maybe 10 minutes then dead, or 5 minutes then dead repeat over and over. Steps I've taken since browsing the forums:Virus scans/spyware are cleanUsed compressed air on the fan vent to remove a little dust, opened up and sprayed out dust nothing major.Speedfan is reporting cpu temperatures of 65C to 69C at 99% idle.Reseated memory Questions:Would a new battery potentially solve this problem?  I'm not sure how s...

Answer:Battery doesn't charge AND frequent shut down when only on AC power

Hi.  I had the same exact problem and was disappointed that noone answered.  After further research, I tried a "hard reset" and that seemed to do the trick.  Maybe it will work for you too.  To hard reset your laptop: Turn off machine, remove battery, remove power lead then hold down power button for ten seconds.  Good luck.

Hi, I have a T61 14" widescreen laptop and for some time I see a strange behavior of my battery and the Power Manager. Sometimes the battery just doesn't charge. For days. Power Manager was set to "Optimize for battery lifespan", then I changed to "Always fully charge" and to "Custom" with Threshold at 75%. Now my battery is down to 38% and won't charge. I even tried a Battery gauge reset but when I start it the screen switches to brightness level 11 for a few seconds, the battery gauge reset icon appears in the taskbar and disappears after a few seconds. No error message whatsoever. Power Manager info:65W AC adapter attachedStatus: no activityRemaining Percentage: 38%Remaining Time: -Remaining capacity: 18.87WhFull charge capacity: 50.08WhCurrent 0.00AVoltage 11.43VWattage -Temperature -27C   <---- ISN'T THIS ODD?!?171 cyclesBattery is from Panasonic2 years old (manufactured 11/07, first use 03/08)Design Capacity 56.16WhDesign Voltage 10.80V Since my ultrabay battery died last year out of the blue at the age of 14 months I think there is something wrong with my computer.

There is a thermal probe attached to one of the battery cell, and the power manager reads the temp reading from that.

Hi.

I bought my M50 about 6 weeks ago knowing i had a Couple of years work in Goa India. My problem is since i have arrived the bloody thing will only work with the charger plugged in. The battery is showing only 12% full and wont go any higher.

I've put a meter over the charger and it seems fine. A local computer repair shop has suggested that it may be a internal fuse that has blown but he would need to open the laptop up to change it. This would invalidate my warranty.

The closest Toshiba repair centre is in Mumbai which is nearly 600miles away.

What should i do?? Help!!

Answer:Equium M50: battery power satatus stays on 12% and wont charge

Hi

If it?s not possible to charge the battery so either there is something wrong with the power supply electronic on the motherboard or the battery has a malfunction. I suppose the battery could be faulty.

However, according to your posting the notebook is about 6 weeks old and the warranty should cover all replacement. I wouldn?t recommend trying fixing the problem yourself because of the warranty. Furthermore I don?t think that you have enough experience and necessary tools to locate the malfunction.
Unfortunately, I don?t see any other possibility as to contact the Toshiba service partner in your country. I?m sure the guys will help you.

I have a Lenovo Y430 IdeaPad laptop.  Last weekend I noticed the battery was low, which was odd since the laptop was plugged into the ac/dc charger.  I determined that the charger was bad, as the light on the power brick was not on, even though it was plugged in. Ordered a new Lenovo ac/dc charger. While I waited for that to arrive, I didn't use the laptop as it was almost out of juice.  The last time I looked at it, the low battery light was flashing and it wouldn't turn on, which I expected as the battery was empty.  The last time the laptop was used, it was shut down correctly. New charger arrived last night; plugged it in to the laptop and nothing happens.  Battery charging light doesn't come on, nor does the unit boot up even though plugged into the wall with the charger.  Charger is good; light on power brick comes on and I verified I'm getting good voltage out of the plug.  Hard drive is good as well; I pulled that out and verified that it still works and all data is still there.  I've tried unplugging the battery for a while, and plugging the charger in without the battery in the laptop and nothing happens.  The unit acts as if it's getting no juice at all. My IT guy at work believes the battery is shot, and won't take a charge.  He believes I should purchase a new battery and believes that the Y430 can't power up without a good battery in place.   Can anyone confirm that? I'm just trying ...

Answer:Y430 battery/charger problems - Laptop won't charge or power up

he may be right but it may be not the only reason that your battery is dead. ( may cause something else )try to remove your battery, plug into the ac/dc, and if your computer works fine, i can say, i'm sure you are having issue with your battery. and if you have valid warranty, don't buy it, ask lenovo to change it.to learn that you can call support line for US : 1-800-426-7378

Just received my new T430s and the first thing I tried to do is insert the 3 cell Li-ion bay battery from my T420s into it. However, during boot up system says it does not recogise this type of battery (ESC key needed to get pass this screen to continue bootup).
In the power manager, the battery will shows up, and the T430s can use the battery normally. However, it just refuse to charge it. I have tried to update battery firmware and read any FAQ in the T430s manual or lenovo website. Nothing shows up. It is weird that such an advance battery cannot be used in a new laptop just 1/2 generation from the last one. I saw from lenovo website that the new 3 cell battery is Type 43.
 
Has anyone using Tx30 laptops successfully use this battery? Thank you

Answer:Lenovo T430s can draw power from 3 cell bay battery but cannot charge

The T430s employs the new Rapid Charge feature. This requires a new generation of batteries that are incompatible with the old. 
 
I was able to find this statement about main batteries:
New battery models (70+, 70++, 81+, 82+) feature a hardware authentication chip. These batteries will work in 2012 and older ThinkPads. Existing battery models (55, 55+, 55++, 66+) do not have a hardware authentication chip and will be recognized, but not be charged, in 2012 ThinkPads.
This doesn't mention your model 42 battery but the T430s announcement did include a new model 43 3-cell battery (0A36310) so it's likely the same restriction applies.

Hi,
I have a Dell XPS 13 (9350-4891) with BIOS version 1.2.3 installed.
Here's what I'd like to achieve: The battery should only start charging at 60% charge or lower. In case that it's charging, the maximum charge should be 90%. So for example if the current charge is 74% and I plug the AC in, the battery should NOT start charging (because it's over 60%). 
Here's what I already tried:
1) BIOS menu: Settings -> Power Management -> Primary Battery Charge Configuration. Then I selected "Custom" and entered the values from above. Result: No matter what the current charge is, the battery starts charging anyways when I plug the AC in. So for example if the current charge is 74% and I plug the AC in, the battery starts charging.
2) Dell Command Power Manager: I installed the software and set the settings like in the BIOS menu in 1). Same result as in 1). Charging starts, whatever the current charging level is.
3) Dell Command Power Manager: I also tried to use this software. Same result as in 1) and 2).

Thanks a lot for any helpful reply!

I left my T61 on standby with little battery juice left last night. When I woke up and tried turning it on the next day, it would not start up. So, instantly I think it's a battery problem and that it just doesn't have enough juice in it.  When I first plugged the AC in, the battery light was flashing orange, but after awhile it turned green then would flash occasionally. After 2 hours of charging, the green stops flashing and so I attempt to press the power button and still nothing.  I read in some previous posts that this may be a memory problem. Does this seem like a memory problem because I left it on standby? I called the Lenovo support people and they told me to try taking the battery and AC out and to push the power button 10 times and so I did, but still no response. Lenovo told me that it might just be a motherboard problem, what do you think Lenovo community?  

Answer:Battery and Charge light green, but won't start up

Hi ayellow,Having seen similar posts on forum, the consensus suggests the fix to your problem is indeed a motherboard replacement. Hope it helps.

I'm having an issue where custom battery charge thresholds aren't being respected on my E5550 when I plug my laptop into AC power.
Steps to replicate:
Using Dell Command | Power Manager, set custom battery settings such that the battery will start charging at 80% and stop charging at 90%.
Unplug from AC power.
Discharge the battery to anywhere below 90% but not below 80%.
Plug-in to AC power.
Result:
The battery will charge when the laptop is connected to AC power despite the battery charge state being above the custom 'start charge' point of 80%.
Desired outcome:
The battery should not charge unless it is is below the custom 'start charge' point.

Using V 2.1.1 of Power Manager and the A13 (latest) BIOS.
This looks like a bug in the battery charger firmware to me. Anyone else?

Hi, I dug up my trusty X41 from back in the day, and realized it won't charge. Lenovo replaced the motherboard / harddrive / screen under warranty a couple years ago, and I haven't really used it since. I found it would die when unplugged, so I thought the battery was dead. I purchased a replacement battery, but get the same problem.  I've babied this machine since I purchased it new back in 2007.  I have a T420 from work, so I'm not in a rush to fix my X41 - but it's annoying that it doesn't seem to work properly with all these new parts and so little use. My IT staff is pondering a swtich to HP machines, which I've opposed in the past, but starting to have doubts. I'd appreciate any advice if you've seen similar issues. Thanks for your help!    

Answer:X41 Charging Issues? Shuts off when power cable unplugged, doesn't charge battery

hey harveyxiao,it is a high possibility that the metal terminal of the X41 might be damage, therefore even if you're using a new battery; you will still need to have a direct power supply to the unit.curiously enough, when you have the power supply connected and the battery pack inserted, at the windows taskbar at the right hand corner, does it show that it is charging ?

So, my issue that ive looked everywhere for a solution to is this.  I was about to give this laptop to someone and I reformatted the hard drive to clean it up before doing so.  After this I went to dells site and loaded up the drivers for this machine.  All is fine up till this point.  Then I updated the bios to the newest version a12, and all went fine.

Well, later that day I needed to unplug the laptop and go to a different room and It just turned off after I unplugged it.  It wouldnt turn on with battery power either.  Plugged it back in and it loads fine but the battery is stuck on 36 percent charge and says not charging.  Now im getting a message saying the battery needs to be replaced as well, which is *** because I know that the battery was working just fine before this day.  Not only that why wont a battery with 36 percent charge turn on the laptop?  Its got the flashing red battery symbol when powered on with the ac adapter but without the computer on, but still plugged in, the battery doesnt charge or have any lights. 

I have already tried the uninstalling of the acpi trick, as well as the taking the battery out while its running, or taking it out purging the power and reseating.  Ive tried all the common tricks to no avail.  Not sure whats going on but I know this battery was good, and it still says 36 percent but wont charge and wont power the laptop on.  Hope someone can help.

Thanks Gary

Answer:DELL VOSTRO 3500 BATTERY ISSUE (not charging and wont power on computer with charge) HELP!

First check:  make sure the BIOS (F2 at powerup) recognizes the AC adapter.  If it does not, the battery will not charge. 
If the AC adapter is not recognized, try another Dell OEM adapter.  If that doesn't solve the problem, replace the DC jack:
http://www.parts-people.com/index.php?action=item&id=9935
And if that doesn't solve the problem, replace the mainboard.
If the AC adapter IS recognized, but the battery will not charge, unplug the system, remove the battery and hold the power button for 30 sec.  Try again -- if the battery still won't charge, odds are the battery itself is bad.
If the battery is original to the system, it's about four years old - well past its expected lifespan.

See if a power reset gets it working. If the battery is not removable there should be a switch on the bottom to "disconnect" the battery internally.
 
When it is just sitting there, not powered on obviously, do you see a battery charging light when everything is connected?

Sorry for the double post, mods. Mistakenly posted to A instead of C.

Toshiba Satellite C50-A-156 battery fully died, now wont charge. Turns only for a second before turning off.

The laptop is connected to mains 99% of the time. I took it off the mains and the battery seemingly died completely.

I attached it to the charger, left it for ten or so minutes and tried turning it on only for it to die after a second or two. The light went from orange initially to the usual white, but the white seems duller/dimmer than usual. The fan starts but no response from the display. I tried holding the power button down after removing the battery and the charger but the same result. I've tried starting using just the mains without the battery, same result.

Any guidance would be appreciated as I'm at a loss with a seemingly bricked laptop out of absolutely nowhere, unsure of what the above symptoms suggest. Would appreciate some feedback before taking it to a tech and being charged for being told to buy a new battery/charger. My best guess is it's fried, in spite of the previously quiet and functioning fan or the CMOS is dead and needs replacing.

I've left it it to charge overnight and, fingers crossed, it'll be working by the morning.

Update since last night. I didn't remove the battery before leaving to charge. Will give it another 24 hours. I also went and spoke to a tech who tell me he'll diagnose without any expense.

I've have my Sattelite L300D since April last year, and suddenly my laptop won't start when the net adapter is not connected. Battery says 100% (Fully loaded) when I'm connected, and started the system.

Anyone any idea why my laptop's not starting on battery alone?

Hi!

In your case I would go to a local ASP (authorized service provider) and let check your laptop from these technicians.
I think it?s a hardware problem, maybe the battery is faulty and so you can only start the laptop with AC/DC adapter.

As per the query we understood that you are looking to use the power adapter when battery connected in your Lenovo Y40 laptop.
 
You can use the adapter while battery connect and fully charged, when the adapter is connected the system takes the power from the adapter when the adapter is disconnected the system takes the power from the battery.
 
Hope this helps. Do post back if the issue persists!                                                   
 
Best regards,                                                          
 
Ashwin. S
