T440 will not power on after battery error

Question: T440 will not power on after battery error

The other night I was working on my T440 and all of a sudden the screen flashed and powered off. At the very last moment I seen a critically low battery error. I immediately plugged it ina nd tried to power on again, I got to the splash screen, then it flashed the battery error again and shutdown. I ordered a Lenovo battery of the same exact size brand new installed it and now I am not getting anything. I allowed the unit to charge while plugged in for a little while and still nothing. Does anyone have any suggestions?

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.

I have a Lenovo Thinkpad T440 and the batteries are showing battery error in the Power Manager. I am unable to update my BIOS to see if that will solve it and my batteries don't seem to be eligible for a Firmware update. My Warranty is also expired. Anyone have any suggestions? error is showing up on both batteries  (Front internal and rear removable). Laptop works fine when plugged in but will not power on if it does not have a charger connected. Batteries don't charge at all (With or without it being powered on) All suggestions welcome. Would prefer not to have to get a new battery set as these ones are relatively new and shouldn't be throwing this error. I do not have a spare Thinkpad I can test the batteries in or that I can test a known good battery from.

I have a T440 that just started giving errors when connected to an external AC power supply.  When an AC power supply is connected and batteries are installed, I get an error message every few seconds that matches the one described int he KB article "ThinkPad T440p / T540p screen flicker, brightness changing or switching to airplane mode while on AC."  It looks like this:The screen becomes dim when this error comes up and the batteries stop charging.  The screen then becomes brighter again and the same error comes up. The cycle lasts a few seconds and repeats.Essentially the system seems to think the AC supply is being connected and disconnected over and over.   I do not use a dock.I have tried 3 different AC adapters (PNs 45N0358, 45N0312, and 45N0482), multiple different wall receptacles, and also tried connecting to a docking station, all with the same results.  When no AC power is connected (running off of batteries only) everything runs normally.  When both batteries are removed (running off of AC power only) everything runs normally.  The issue only occurs when one or both batteries are in the computer and trying to charge.The fact that I get the same issue when connecting to a docking station rather than the normal external AC power supply, combined with the fact that it runs fine off of AC when batteries are removed, makes me think this is not a simple connection issue with the power jack or power connector.Any input would be mu...

Answer:T440 gives AC power error when batteries are present

This is a known issue. The fix is to install the latest version of Power Manager and add the registry file described at https://forums.lenovo.com/t5/ThinkPad-W-Series-Laptops/W540-charging-bug-WiFi-OFF-no-charge/m-p/1498... You may also want to read https://forums.lenovo.com/t5/ThinkVantage-Technologies/Power-Manager-Problem-With-quot-Enable-auto-d...I agree that this is not intuitive at all because the error message blames the dock rather than explaining that it is related to an Airplane Mode setting in Power Manager.

Hi, recently i bought from ebay an thinkpad t440 20B7-S0FV11 i5 4300u with 8Gb of RAM and 500Gb hdd.This laptop came without front battery (internal), it just came with the external one so i bought one internal battery on the internet and put it myself on my laptop.I press the reset button on the button of the laptop and turn it on.The issue is that windows (and also ubuntu) didn't recognize the battery. Windows say: "battery not detected"!I already update BIOS and everything and the battery still not detected.Initially, i thought that the battery was damaged but i charged it directly from the external battery, plug it inside of my laptop and turn it on. The laptop still not recognized the battery (and did not charge it neither), and windows says: Battery not detected!But the laptop work without external battery and charger, just with internal battery! (despite that not charging or detected) So i thought that the lithium cells are probably ok.I want to know if it's a battery problem, some lenovo firmware on battery (since battery came from china) or some problem with laptop!Thank you all.(sorry for my english)

Answer:T440 external battery not charging

Hi Valdemar_d,
 
Welcome to Lenovo Community!
 
As per the query we understood that you are facing the issue with External battery not charging on your ThinkPad T440.
 
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.
 
Best regards,
Hemanth Kumar

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?

Hi all, recently I bought Lenovo t440. How long should last battery (s) in this laptop in normal or power saving use with screen at 65-80 %? I know this laptop have two batteries , and both of them are 3 cell right ? Extended battery have 6 cell, which I don't have, but might I would  buy it . I noticed my both batteries last max 3,5 hours max 4. This is from I what know - slightly short.  Before I buy some of this batteries I would like to know which one is maybe fault, or worst of them. Maybe is faulty inside battery, maybe plug in one.  My battery indicator in win 8.1 shows both bAtteries ... It seems windows recognize capacity or remaining storage from both of batteries in same time,or, should I say, it seems my laptop is running on power from both of them in real time... Maybe laptop should drain batteries one by one ? Ok, if this is normal, let's skip it     main question is still,how to check each batterie health / or one by one in mY T440  to see which one is maybe faulty or less good, for potential replacement ?   thank you all

Hello The subject of this message says it all. When I want to start my T440 without AC power, it happens quite often that the machine will not start at all - no lights, nothing. In such a case I am forced to plug in AC power just for 1 second, hit the power button and then my T440 will start. Sometimes it starts without AC power, but then again sometimes it does not. it seems random. Note: I am not talking about resuming from hibernation or etc, I am talking about a new, fresh start.I searched the internet in detail for a solution, but no result to my problem. Of course I read from other users having problems starting up their T440, but never exactly the same problem.My battery lasts for a couple of hours.  What to do? I am in Myanmar, far away from support. I tried many things already, including taking batteries out, start, turn off, start again.... Many thanks for your help.

We recently purchased a T440 touch and upgraded to Win 8.1.  After I joined it to our network and install Bitlocker, the laptop no longer is able to power off.  The only way I am able to acutally shut down the laptop is to take out the battery.  Any time I shut down (shut down from the menu, or even press and hold the power button for 15-30 seconds) the laptop closes and then 5 seconds later it powers back up and goes to the bitlocker prompt.  Bitlocker has a feature where it will power down the laptop if you don't interact with it but even this doesn't work.  It will shut down and then seconds later power back up. Anyone else deal with this or hear about it? Thanks.

Hello forum, I bought a like-new T440 last week (500 GB+16 GB, 8 GB RAM, i5) & my experience so far has not been good at all.

New ThinkPad T440 and Basic Dock, running Windows 7 x64. If you sleep the machine, put it in the dock and power on, it comes up fine, and everything works. But if the machine is powered off when placed in the dock, when you press the dock power button it turns on but never completes booting (never plays the Windows "boot song"). The machine is up to date with all Lenovo drivers and software. Lenovo support sent me a new dock, it made no difference. Has anyone else seen this problem? It looks like the power button on the dock has an LED light in its center. Is it supposed to light? Mine does not. Thanks, Bob O'Hara

Does the ThinkPad T440 utilise the Always On Always Connected (AOAC) power mode feature?













Solved!

Go to Solution.

Answer:T440 - does it utilise the AOAC power mode feature?

It does not.  That's a tablet-only feature, which requires special support from chipset/firmware.  Traditional notebook systems (like T440) do not support this mode.
 
By the way, the feature has been renamed several times by Microsoft:
Always On Always Connected (AOAC) --> Connected Standby (CS) --> InstantGo

Hi,I have a Toshiba X305 laptop which thinks it's running on battery power when it's plugged into AC power and says it's plugged in when it's not. The only exception is when it gets low on power and I plug it back in, it says it's plugged in and charging. Once it reaches a certain threshold however (about 90% charged), it reverts to the "battery power" icon.This problem began when I installed Windows XP instead of Vista which it came with.Any ideas on how to fix this?-darryl

I have a strange issue. I have a Lenovo T60 laptop and I am experiencing problems with the power management/power guage.

It will often show the battery not installed (power gauge is a greyish-white color with dashed lines) or it shows a red X. It does not matter if I am on AC power or on Battery power, it will show the full range of power, battery level, not installed, or an error.

I have searched Lenovo's site and I seem to remember seeing an FAQ about this, but now that I need it, I cannot find it.

What can I check or do to stop this? While it is annoying, I am not sure if I am having a battery problem or not. I did check my battery on Lenovo's site to see if it was recalled and it is not.

I do appreciate any help that any one can give me.

Thanks!

Recently installed Win 8 on my x220t.  I am now getting a ''Battery 2 - there is an error'' message related to the slice battery. All the related info to this online tell me to look up various information for the battery in the Power Manager, which I can not install, as its for Win 7 only. Any suggestions? I have installed the Lenovo System Update app to ensure I get all the latest drivers. I did find the 'Lenovo Battery Firmware Update Utility for Windows 8' here but my battery part number is not in the list.

Answer:Win 8 x220t battery error - and no Power Manager

ThinkPad T520, Win7 Pro 64.  TVSU updates Power Manager to V. 6.38. Immediately on reboot notification area shows 0% power and a message stating that a battery error has occurred. The battery LED is now blinking orange and the battery will not charge. Considering that the battery was fully charged and had only 31 cycles on it (although it dates to October 2011) I can only assume that the software has killed the battery. Again, prior to the update there were no indications that the battery was malfunctioning or even losing capacity. Uninstalling Power Manaager  did not help. Re-installing Power Manager did not help. Is there a way to reset the battery? Am I locked in to buying a Lenovo battery to avoid task bar notifications of a non-genuine battery? Any other ideas would be greatly appreciated. Here in Mexico these batteries are very, very expensive.

Answer:Battery Error after Power Manager Update

Hey there mixz1,
 
Have you seen this article on how to perform a battery guage reset? Additionally, it may be wise to remove the battery and AC, then press and hold the power button several times to clear residual capacitance and then re-attach them and restart. I hope this helps.

I am having Inspiron-6400 (XP SP3) laptop. 2 years old. Suddenly I am getting the following message for the past two days:
"Your system will operate slower and the battery will not charge. Please connect a Dell 65W AC adapter or higher for best system operation."
That error message comes when I plug in the AC adapter to go to AC from battery.
It results in Battery not charging. That is a big problem. The tray-icon just shows 'On AC Power' and the 'Charging' indication does not appear any more.
A related message is also seen when I reboot the laptop, at the start itself. That message adds a suggestion by saying 'Try to reseat the power adapter'. Reseating it does not help. Though, a couple of times it helped. So I am not sure what this mechanical / reseating thing has to do with this error.
Overall, it is frustrating. It will be great if someone can help me with the exact solution for this, other than going to Dell requesting for paid-service support.

Here is the scenario.1) At work, my R60 is docked and connected to a wired Ethernet connection.  Access Connections is using a profile that supports both wired and wireless connections.2) I power off my R60 and go home.3) At home, I power up on battery power.  I expect Access Connections to try my work profile, fail, and switch to my home profile.  Instead, Access Connections quickly (too quickly like it hasn't even tried the wireless connection from my work profile) fails and quits. 4) I manually start Access Connections from the system tray, switch to my home profile, and watch it quickly fail.  If I click, "Help me fix this", the diagnostics window tells me:Wireless stack initialization failed.  Error code 108.5) Restart and power-off, power-on will not fix this problem as long as I am on battery power.  If I power-off, plug in the AC adapter, and power-on, everything works correctly.What could be wrong here?

Answer:Access Connections fails with 108 error on battery power

Have you already updated Access Connection to the most up-to-date version?

A week or so ago my T420 Thinkpad started giving me problems. After being shut down, it would not boot up using just battery power, but it does boot up when running on A/C power. Once booted up, I can unplug the AC and it runs fine on battery. I can go into sleep mode and turn it back on with battery power without a problem. I just got  a new battery (thinking it was a battery issue) and the same thing is still happening. Any ideas??

Answer:T420 Doesnt Boot With Battery Power, But Does Run on Battery Power

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!

Thinkpad X240 running Win 7 Pro. Has an internal battery and a removable battery. Our power supply (240v) was a little shaky yesterday and the AC adapter popped a couple times before I unplugged it to give it a rest. The last chance I had to confirm, it was charging the computer correctly. Then the power gave out completely. Today power is back and my battery is drained. When I plug in the adapter, power light blinks three times, I believe indicating that it is getting power from the adapter. When I try to boot the computer, I get the ThinkPad launch screen, and then I immediately get a 190 Critical Battery Error. I also get the error if I press enter for special options. I get the same behavior if I plug into a 240-120v converter instead of the 240v power outlet. The tongue test confirms that there is power coming out of the adapter, but I don't have access to a multimeter. I have tried using the pinhole reset before the 190 error, but the behavior doesn't change. I have also tried this code: http://www.masnick.com/2007/09/07/the-secret-thinkpad-powerbutton-code-to-bring-dead-laptops-back-to... but I have not removed the internal battery so the computer begins to boot when I start entering the combination. I am in a remote location and I prefer to address myself if at all possible.

Answer:Thinkpad X240 doesn't use power from AC adapter + 190 critical battery error

I found someone else with a recent Lenovo model that used the same charger, and their charger was able to charge the battery. So I suspect this is most likely a fried adapter. Although if there are any ideas, I will welcome them.

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
 
Best Regards,

I have a T440 that is giving a fan error message and then shuts off immediately. And, of course it just went out of warranty last month! Any ideas as how to fix?













Solved!

Go to Solution.

Answer:T440 giving Fan Error

It is a pain that it just went out of warranty. That seems early for a fan to die. I don't know how handy you are about doing things yourself. You just need a screwdriver, but some people are comfortable doing things like that and some are not. I am assuming the problem is the fan itself, because the only other part involved is the motherboard which is a much bigger issue. I would say that in 90% of cases it is the fan itself. The fan can be accessed by removing the bottom cover. The fan can then be removed and replaced. On newer machines, I always suggest a new fan, as opposed to a used one, which should come pre-pasted. Here is a link to the service manual. See what you think:https://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles_pdf/t440_hmm_en_sp40a26000_01.pdf

A while back, we discovered the battery maintenance error, where the "stop charging at 90%" feature would cause the battery to only charge partially to like 50% but read that it was fully charged, and then it would turn off early. This was the thread. I know it's a BIOS issue, and I will update eventually, but the partial charge happened to me again, and it got me thinking: Do I really need the Power Manager? I use the Power Manager to configure Turbo Boost clock speed and all that, and I suppose the Turbo+ button does crank up the fan, but I can use TPFancontrol to manually control the fan, and I found that Windows power settings by itself allows me to set the clock speed however I want, using a percentage. Setting all the numbers at 45% parks the clockspeed at 1.2GHz, a good compromise for battery life and performance. The best Power Manager can do is to cycle between 700Mhz all the way up to 2.7Ghz, which throws battery life out the window. So, will I lose anything by just uninstalling Power Manager?

Answer:Life without Lenovo Power Manager: Any thoughts? [battery issue, charging error]

Technically the answer is no, Power Manager is optional.  However, it is a good option for Windows 7 users. It does expose more power management to the user than the power settings under Control panel. Until they release the Windows 8 version and I run it for a few weeks, I won't know what to say about that environment.

Not sure if there's any known quirks with that combination of hardware and software, but it sounds to me like the battery had a spontaneous failure, in which case you should just get it replaced under warranty.

So today i was testing my laptop with other searching some troubles on main board. Tension was not stable until battery was fully charged. Then after 5 minutes (time needs to drop battery level under 60% from 93%) i was again not stable (+/- 1A). So I think it is problem with battery, I'm right?Last thing: is there any software to format battery for Lenovo Y530? I mean I want to try repair my battery if this is possible. I wanted to format battery from my BIOS but there is any option to do this. Is there any software which allows to format battery manually without BIOS? Or just I must upgrade BIOS?

On a new laptop lenovo L520 (W7P-64b) the orange battery indicator is blinking while the battary is actually full.Power management says the battery is full showing 96 % in the large green battery icon on the task bar next to the power plug icon..The laptop is connected to AC power.The Windows icon on the taskbar shows a full battery and the power plug.Power management says the battery is charged and in a good condition and only 7 load cycles are counted. (but orange light is blinking) When disconnecting from power, the orange light still blinks, power management still shows a full battery (just removing the power plug icon)The windows icon switches to an empty battery icon.The laptop still works but after a few minutes it shuts down due to lack of power. (Note, not immediately) For other lenovo models I've seen similar issues suggesting old batteries or broken fuses. But when I shut down the computer, unplug power the light keeps blinking for a few seconds and that switches off.  When a restart a l few seconds later every thing is oke: battery full, green steady light etc.So, because a restart does not fix fuses or revives batteries I think it is a new issue. Please suggest what to do other than reboot. tia,Bert

Hello everyone,
I have been having a problem with my laptop recently. A few weeks ago my laptop turned off, and wouldn't turn back on. I did some googling, and found suggestions to remove the memory, SSD, and CMOS battery, wait, then put them  back in and try again. When I did that, it didn't work the first few power button presses, but then it turned on. It has been consistent like that. I have the battery out, and on AC only, when I remove AC and CMOS battery, then plug the AC back in, the laptop will boot after hitting the power button a few times.

Any suggestions?

 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...

Hi

I hope someone could help me with my problem.
My toshiba P200-1fc running Vista and updated to latest Bios will not show any light in the battery indicator led if running on battery power.
It's fine if i have it plugged into the mains.

I only updated the Bios to see if it sorted the problem .
The battery charges fine orange then blue to say fully charged but I only have the taskbar icon to see how much power is left.

Also the wife has got a U300 and the same problem has happend. I restored the laptop to a earlier time and this did not fix the problem.
I also unstalled some programs (antivius/firewall) but no joy.

It may be something simple i hope.
Thanks for any help

Sorry but you are completely wrong!!!

The battery LED doesn?t light if the AC adaptor was disconnected!!!

The battery LED shows only 2 signals; orange and blue (sometimes green on different models)

If the battery is not fully charged and the AC is connected the battery LED shows orange. If the battery is fully charged then the LED switches to blue (green)

Please don?t be mad at me but I think you should firstly check you user manual before posting some ?gossips? about any possible ?bugs??

Hi,I have problems with performance when unplugging my ideapad s400 touch, and it does not seem to be related to windows or intel graphics power settings. Example, while plugged in with full battery (not charging), I can play Skyrim at 600x800 with 28-30 fps (all shadows turned off and with reduced textures, in case you are wondering how that is possible) But when I unplug, or the computer is charging, the game will be only barely playable at  480x640 with 18-26 fps (besides res. of course same settings). In both cases, the intel graphics options and in the Lenovo Energy Management is set to the high/max performance settings. So I am wondering if there are some hidden Bios power management or some other hidden power management going on, when it is unplugged or charging?Or if simply the battery can not deliver the same juice as when it is plugged in? Thanks for any help,L

Answer:ideapad s400 touch bios or other hidden power management while on battery? or battery just weak?

hi x8lars,
 
Welcome to Lenovo Community Forums!
 
Can you try changing the power plan on your system to a High Performance Settings,
   Also check the Advanced power settings and make sure that the Maximum  Processor start and minimum are set the same with the Plugged in.
 
Let me know your settings,
Cheers!

My battery (FRU: 42t4957) is stuck at 2% and refuses to charge:I kept it at 40-50% most of the time by changing battery threshold. Total cycle count was about 80 (84 now) first use date 2013-03.On Saturday I tried to run a "discharge-charge-discharge-charge" cycle (by watching some movies) to reset the gauge of my battery. During 2nd discharge my laptop hibernated due to low charge much earlier than expected, when I turned it on it showed that the max capacity is 28 Wh and the battery is in the "poor" condition.I tried to perform automatic gauge reset but didn't get much (29 Wh). I updated power manager and performed another automatic reset which failed too.So I tried to make a manual reset and left my laptop paying a movie for a night. On Monday I plugged my AC adapter in but found out that the battery won't charge: "a battery error has occurred the battery cannot be charged".I cleared residual capacitance by pushing the power button several times and reset the BIOS to defaults but got nothing.If this problem can't be sold I would like to know the reason of it to avoid such things in the future. While googling this forum I met contradictory opinions on battery reset: ones say that it's extremely harmful because battery "doesn't like" to be discharged to 0%, others say its harmless.

I am using a G500s laptop and  it was having the following issues *laptop was not charging * both battery and power indicator keeps on blinking when the laptop is connected to power. Even when the laptop is switched off and when it is connected to a charger the power and power indicators are blinking. I gave my laptop for repair and they informed that they had replaced the motherboard and the laptop was working fine for 2 months. Again the same issue is happening. Please advise me what can be the issue?

So, I had opened months ago a thread here about the short battery time with the T470P. I got my hands on the biggest available battery (72Wh), but still manage, even after a gauge reset, to get around 5h battery time, only using Firefox, and minimal Words/PDF. All on POWER saving mode. What's going wrong with the T470P that it wont even reach half of its promised 12h battery time? (I know those are Airplane mode numbers, but 5h is a joke compared to those)

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

Answer:Battery - Vista is not able the retrieve the power options for the battery

Hi

To be honest I have no idea what you are talking about.
The Vista power options are a part of the Vista OS and you don?t need to install anything.

But on Toshiba notebook the Vista power option would be extended by some Toshiba power options.
Are you speaking about this Power Saver options?
If yes, then I would recommend reinstalling the VAP (value added package) because these power options are a part of VAP.

Over the last few months I noticed that the battery meter on my Dell Inspiron E1505 laptop was blinking red to green and back... so having had this laptop for several years, I assumed that I would need a new battery soon. The adapter power cord was also beginning to lose some of its covering near the plug in site so I ordered both a new battery and power cord. (That was about 2 weeks ago).

Upon receiving my order, I was very pleased to see that when I installed the new battery and new cord, the battery already had some charge (I didn't note how much). I felt relieved to have my mind at ease that all was now well with my computer. (little did I know that I'd be needing help less than two weeks later!).

Important note... I very rarely use my laptop without the power cord... (past experience proved to be frustrating because I always needed more time than the battery provided.)

I've probably only used the laptop "on battery"... a few dozen times over the last 3 years!

Now... I am in a dilemma!

Yesterday, I took the laptop with me out of town when my husband and I did some real estate hunting.
Instead of using the laptop on battery... we had it plugged into a special power converter for use in the car. I noticed that whenever we stopped and turned off the ignition... the laptop would lose it's power immediately, and as we resumed our travel... I'd have to restart the computer... and there would be the "black & white" warning... Read more

Recently I noticed that the amber LED on my HP Probook 650 G1 flashing constantly, even when the laptop is powered off.   The System Tray battery indication is 100%, fully charged, when on AC power and 100% on battery power shortly after undocking.    I find the Probook won't power up if AC power is not available (no response when pressing power button) but remains powered when I remove it from the docking station.    Have the electronics that control this LED flashing and power up when not on AC gone bad?    Is this an indication of other failure? thanks

This problem occurred with prior Win 7 Home O/S, so I upgraded to Windows 10. Heavens-to-Mergatroid!  This laptop runs just fine when only battery is powering it.  However, once I also plug in the power cord, the O/S does a hard crash within 1 to 3 minutes. How special! I can get about 2.5 to 3 hours when using the battery, but not if I also plug in the power cord.  That means that when the battery gets low I must perform a standard shutdown and then insert the power cord which recharges the battery if I don't turn  on computer.  If I then start the computer with both connected, it crashes.  I am not patient enough to live with a computer that has to be recharged every couple of hours.  HELP! I suspected a heating issue, so I took the back panels off and thoroghly cleaned the fan vents and other cracks and crevices using canned air, but this did not fix the problem.  Since in runs just fine on the battery, I deduce it is NOT a heating issue, neither dust or heat paste issues.  (I also used a cooling mat to no avail) Im 70 years old living in God's waiting room, but parts of my body are 18 to 30.  However, I do have "Essential Tremors" in both hands so I cannot do a full laptop disassembly even if I want to, which I don't.  I cannot afford to pay a computer repair shop $100 or more to try a fix this vexing power issue.  Other than hocking my car (it's too old also) to buy a new laptop, does an...

Hi, my girlfriend in Beijing has an Acer Aspire S3 latop. She bought a new battery for it a while back and told me it was no good. I was in Beijing recently messing around with it and found that actually the battery is fine (lasts for >4 hours) but when unplugged and running on battery power, the laptop often just cuts out suddenly (loss of power). I took the battery out and had a look and cleaned all the connections but they seem fine.

The next part is the strange part and which I hope might give someone a clue as to what's going on...

When it cuts out, it will never restart again unless the mains power cable is plugged back into the laptop. As soon as that's done and the power button is pressed, it starts up again and the cable can be taken out immediately (I mean immediately - you can plug the cable in, push the "power on" button and pull the cable back out in less than a second) and it will start up and run fine on battery again... until the next time it suddenly cuts out without warning.

Because any unsaved data is lost and because the laptop cannot restart without the power adaptor, this very portable and light laptop is now reduced to having to be kept at home all the time and plugged in, which is exactly the opposite of what she bought it for.

Anybody have any idea what the problem could be or suggest some tests that could be done to find out? She took it to a local computer shop but the guys there had no idea.

Thanks in advance for any adv... Read more

I have some T60 battery's here that cannot be charged. At the moment i have 5. One of those has just a cycle count of 51. The others have a cycle count of 113, 346, 481 and the last one sais "No battery installed". All those are between one and two years old. Is this normal for the T60 series that the battary dies that quick?  I've allready looked for the replacement program, but none of those battery's is in that range for replacement. I think the problem is that the laptop's where on stock for a month or 2 and they didn't removed the battery before placing it in stock. What can i do?

Answer:T60 - A battery error has occured. The battery cannot be charged. Replace the battery.

Hi Roman78, Wlcome to the forum! If the batteries do not fall under the recall you will have to buy some new ones.Most T60 batteries last a long time but some do die early. It happened to me too.Make sure from now on that the batteries are removed before going into storage. Running batteries completely dead is hard on them and there is always a little draw when they are connected.

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

Lenovo is providing faulty batteries to customer for consecutively 3 times!? Issue has dragged for over 1 year and now Support Center says battery warranty is over and request to purchase new battery. If purchasing new battery can solve the issue, why did I need to replace the battery 3 times!? All batteries cycle counts range between 30 to 40 only. (Mostly on AC and recharge threshold is set to recharge at 33%). Lenovo batteries can only last for 3-6 months!? Despite case being escalated to "TOP MANAGEMENT", no response from Lenovo at all for over 1 week! Is this even escalating? Is this so-called "Customer Satisfaction" when satisfaction level is NEGATIVE ONE HUNDRED?

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!!!

Just disassembled my Z580 to check why it wasn't starting up (another thread) as I figured if I'm going to have to get a independent engineers report I might as well open it myself at the same time. Followed all the steps as outlined in the hardware maintenance manual and found no sign of any hardware damage/power surge/blowouts anywhere. I then reassembled the laptop using the same guide (with no extra screws) and placed the battery in (just to confirm I took out the motherboard battery once I could and reinserted it when I was closing up). Much to my confusion and relief that there is some sign of life, the power button, power light, battery light and caps lock light are flashing in that order. A couple of times when I press the power button the touch sensitive volume buttons also flashed, but that's only when I press the power button sometimes. I can't find any info on these lights online. Any quick help would be appreciated

Subject line says it - unit runs fine, battery is is good shape, replaced charger with a new spare.  With PC on the docking station and all plugged in, both batt and power lights green, pushing either the laptop power button or the docking station power button, immediately extinguished both LED's and they remain that way until the laptop is removed from the docking station and the battery is removed and then reinserted into the laptop.  PC will then boot and run normally with battery showing full or nearly full charge.  Power cord can be reinstalled and all goes fine or the PC can be inserted onto the dock and all goes well also.  But, after a normal power down, the restart problem reoccurs, etc.... Any ideas out there? 

Answer:T60P w/Docking Station Battery & Power LED's Go out when Power button pushed rem batt to fix

OK - More Info: Removed it from the docking station and the problem persists, that is, once shutdown, restart will only occur if the battery is removed and then reinserted.  As a test, removed the battery and left it out, attached the power cord, and booted up successsfully.  Ran all day fine without the battery, then shut down without the battery, and next morning, without the battery, would not start.  AC Power light was on, but went out as soon as power button was pushed.  Removed power cord and reinserted it, still no start.  Put battery back in, started fine. So, with no battery, just AC cord, won't restart after a shutdown.  Also, with battery and AC cord, won't restart after a shutdown.  In both cases, however, if battery is installed, or if battery is removed momentarily and reinstalled, it boots up.

Try powering up on AC only - if it will but won't with the battery, the battery is faulty.
If it still won't power up  after the foregoing, the mainboard is bad.

Hi,

it seems that your power supply electronic is damaged!

But at first you can try to un- and reinstall the Toshiba power saver to setup a new power management profile.

You can play it safe and recovery the notebook. This set the OS back to factory defaults and the system should run without problems! But be carefull all your data will be lost after the recovery!

In the end all solutions won't help, you should check the power supply electronic by Service Partner

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.

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

Sometimes, when the device is not plugged in directly, it doesn't get the power it needs. Holding the power button, while you restart it, clears out the temporary ram (no it won't delete anything you have saved) and will give the device access to the ram it needs.

Answer:T440s reenable internal battery without AC power or power lead

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.
