Preferred Solution: Battery firmware has just killed my battery. How do you justify pushing firmware that does this?

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Hi, welcome to the forums.

Here it is the support site link for your model just in case.

I'm guessing that the computer is booting but the battery does not provide any charge, right?

I did not have that issue, but I'm just guessing, What will happen if you apply the battery firmware update again? You can download it manually from the support site: "Lenovo Battery Firmware Update Utility for Windows 10 (32-bit, 64-bit), 8.1 (32-bit, 64-bit), 8 (32-..."

This is what it cames to my mind right now, I hope it helps.

Hi all,
 
After installing of Battery Firmware Update my brand new battery not recognized by notebook anymore.
It is completely dead.  I am fully upsert.
 
So, people, do not use this app if everything is fine. Application is not stable.

Seems like internal battery memory was corrupted due to flashing interruption.
I assumed the root cause is internal software error.
 
I've tried the same on Windows 7/8/XP with all LnvBFU revisions (from v1.2 till v1.15) without any success.
 
But LnvBFU.exe still recognizes the battery, it still able to start flashing.  
And I still have hope to install battery software correctly.
 
Dear Lenovo experts:
1. Please provide steps to correct this error.
2. Please advise how can I get logs of LnvBFU to figure out what's wrong.
3. Please fix this issue in the next LnvBFU revision.
 
Thanks in advance.

Answer:Battery Firmware Update has killed Brand New E420 battery

Hi, I have a comparable problem over here. Got a brand new Lenovo Yoga 260 three weeks ago, worked completely fine until last wednesday. Processed some lenovo updates including Lenovo Solution Centre and Power Management and now my battery is dead. Everytime i turn on my Yoga 260 i get a battery error message after a few minutes that says the battery is not charging and it should be replaced due to a bad condition. When i open up Lenovo Settings and search for energymanagement it displays the same message telling me the battery is defect due to normal wear and it should be replaced. My problem is that the battery worked completely fine until the moment i installed some Lenovo software updates. I hope lenovo support can provide steps to correct this error instead of forcing me to return it and wait 2 -3 weeks. Thanks in advance.

Hi, I suddenly encountered a battery problem in my laptop, IdeaPad Y510P. It seems like other folks have the same problem in Ideapad series.   When I plug in a charger, the laptop shows that battery is charing but, it never goes above 7% (w/ max battery life mode). According to Energy Management, battery status is fine.  After searching similar issues, I think it may be a problem with firmware, but I was not able to find a firmware update for IdeaPad series, Windows 8.1.... I have been using my laptop over a year, but never had this problem before. Can you please guide me through how to fix this issue?  Thanks for your help..!

After that reboot and install it back and see if there is a difference specially on the battery status. Also basing on your statement that the unit is with you for more than a year and you have not encountered any problem except recently it would seem that a battery replacement might be in order. Again before jumping into conclusion check the ac adapter and battery based on the procedure given in your hardware maintenance manual.

Hey, I own a Thinkpad E220 (5380-CTO) and the "Lenovo Thinkpad Toolbox" gives me daily alerts that I have a "critical battery issue". The link leads me to a page to download and update the battery firmware. "Battery Firmware Updates for Main and Slice (external) batteries - ThinkPad Edge E220s, Edge E420s, X1" http://support.lenovo.com/en_US/detail.page?DocID=HT062049&AID=10429688&PID=3719336&CJURL=http%3A%2F... I've gone through all the steps to update the firmware numberous times, including doing the battery recalibration and I STILL get the daily "critical battery error message". Please help, the daily scans eat up RAM and it's annoying that I have to cancel it daily. The battery, from what I can tell, works otherwise. Thanks!

Answer:Thinkpad E220 "Critical Battery Issue" even AFTER updating battery firmware

I do have exactly the same problem: keep getting the "critical battery issue" alert every sinle day! When I want to update the battery firmware, it says it cannot find any batteries that require firmware update. Yet, I get the same "critical battery issue" alert the next morning... This started happenning a few days a ago after I have updated the ThinkVantage Toolbox system; and it is already driving me crazy... Does anyone from Lenovo ever read these community blogs??? It seems like noone cares!

For these devices there is a battery firmware update but not for my battery.Again i know that batterys are getting worse after cycles but this seems to be bug because:1) the battery is 2 weeks old2) the battery shows in the energy manager as 47wh battery and not 57 battery. So the battery manager says "good" and no battery wastage.  Does Lenovo provide the upgrade also for my device and battery? see the links: http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-75738 http://www.lenovoblogs.com/connections/2010/08/update-bios-and-battery-firmware-to-ensure-full-charg...

Answer:Solved: Edge 11 AMD K325 - Battery Problem need Battery Firmware update?

Hello mate, You don't have a problem with your battery. My T510 indicates the same with a 57wh. Under average usage patterns your ThinkPad battery maintains approximately 70% of its power capacity for the first year of operation. Average usage is defined as the number of recharge cycles. A cycle is defined as each time the battery discharges a total of 85% or more and is recharged it counts as one cycle.

Answer:Ideapad Z-500 - Battery firmware updated but still battery not charging

hi Aledef,
 
If you have the Lenovo Energy Management installed, can you check the following:
 
1. For Windows 7:
Ensure that Maximum Battery Life is selected
 
For Windows 8:
Ensure that Conservation Mode is disabled.
 
2. Uninstall the Microsoft ACPI Compliant Control Method under the Device Manager > Battery
   - Link to picture
 
When finished, reboot the machine and observe if the battery is now charing above 59%. If the problem remains, try charging the battery while the computer (about 30mins) and see if it goes pass the 59% mark.
 
If the problem persists, I recommend you contact lenovo on how to go about getting a replacement battery.

Hi, I have Lenovo ThinkPad Edge E330. few months ago I have got a few messages like "Battery Error" (I don't remember the exact text). From that time nothing changed with battery run time, if I remember well. However ,after some time the battery suddenly went from 5ish hours run time to one hour or less. I would guess the problem could be something like this https://support.lenovo.com/us/en/documents/ht001086 but I haven't find any reliable tool from Lenovo to check the battery. Lenovo solution displays "Health: Fair" in the battery status tab. I have also tried to update battery firmware (http://support.lenovo.com/us/en/downloads/ds001322), but it didn't help. My Notebook is still in warranty. Is there any solution for this problem, or should I try reclamation? ThanksJan

Hey.. so I just bought a surface 2.. like new but the battery has a red x and will not charge. I've tried cleaning contacts, uninstalled battery in device manager and most other things. I feel like if I could get the system firmware update it may solve the problem and I can force the windows updates by uninstalling the battery.. when it reboots to install the firmware it show the surface logo and the "please wait while updating" it almost instantly reboots and goes back into windows. Any ideas here? Also is the battery difficult to replace? $16 on Ebay and I may give it a shot.

Hi all,About a week ago I updated the battery firmware on my Thinkpad Edge 13.A few days later, battery started acting crazy, and the next I know, It just died.Up until that update It could still take about 5 hours on battery, but now It's gone to 0 percent and won't charge at all.Power Manager says it "has failed due to normal wear", but that does not seem very normal to me!This is a genuine Thinkpad Battery 73+, model is 42T4858, was 42t4814 before the firmware update.Is there any way to flash the old firmware back? Does anyone has the file for it, or know where I can get it? Any help will be very appreciated.Thanks!

Answer:Edge 13 Battery Firmware

Hi Mosheke,
 
Welcome to the community.
 
As per your concern battery is not charging,  If your battery has much lesser capacity or does not charge at certain level any longer, you may want to perform a gauge reset on the battery.
 
Double-click the green "Power Manager" battery icon near the Windows' system clock, usually at the lower-right corner of the screen. If you cannot find this icon, click "Start," "All Programs," "Access IBM" and "Power Manager."Click the "Battery Information" tab at the top.Click "Battery Maintenance."Click "Perform Reset," and then click "Continue" on the confirmation dialog box. This procedure will take more time to complete, and you should not use your ThinkPad during that time. You will be prompted when the battery reset is complete.
 
Note: make sure AC adapter plug in when performing gauge reset.
 
Afterwards, please check whether the issue get resolved.
 
Regards,
Sameer

Hi, I have a T430s with a defective battery -- its a known problem where the batteries "indicate an incorrect full charge capacity value".  The result is that the laptop shuts down when the battery isn't empty.  Currently, mine shuts down when the charge gets down to 30%. There is a firmware updater -- but it only works on Windows (e.g. there is not bootable CD you can use).  I have (only) Linux installed, so I can't use this.  After shuttling me around between different support services, they told me that they can't help because (a) the laptop is under warranty, but (b) the battery is no longer under warranty.  They also couldn't tell me which battery parts do not have this problem. I tried "hiren's boot cd", which has a "mini XP" that runs from memory.  I tried to run the firmware update tool from this XP, but it refuses to do anything :-(  Its unclear which version of windows will even run the firmware updater! Does anyone know of any way I could update the battery firmware? -BenRI

Answer:Fix battery firmware for T430s under Linux?

You can try using the Windows Preinstallation Environment; it helps me upgrading the management engine on both my T430s and my X201. Remember that upgrading the battery firmware requires not only the firmware updater but also the power management driver.

Hello! I have an x250 notebook.Capacity of my internal battery flows down. Some time i opened lenovo power manager and checked battery. Internal battery is full charged with 12,18V, but external battery is full charged with 12.68V.It is very strange for me. As i know there is no li-ion battery with <4.2V full charge.I recalibrated the battery, no changes.Ok, It is possible that one li-ion battery has lower voltage then other two ones. I checked the voltage - 4.07. 4.07, 4.05 it is great result!Batteries are not charged fully, so capacity is lower then it should be. I found battery FW update for some lenovo notebooks, but i didn't find it for x250.Can you help me?

The Thinkvantage Toolbox is reporting that the battery is not holding charge (down to 32%).  It is less than a year old and has been configured for maximum battery life.  The warranty link brings up a firmware update that won't install successfully.  I've tried the full package, and doing one part at a time.  It always detects the battery, goes to the writing the firmware stage, goes directly to the second try writing n/1334 (I think that's the number) and then fails.  I've let it reboot and try again with the same result. The product is ThinkPad SL510, product id 28479YU, Bios version 6JET85WW(1.43). Any suggestions on how to proceed?  I've seen other posts that suggest that it may be a defective battery, but nothing on how to confirm that. Thanks, Andrew

Answer:[W520] How I know Battery Firmware version and downgrade

If you attach the AC adapter when the battery is at 49%, then it will not charge because it is not below 46%. This is the intended behavior.If the system is charging and discharging between 46% and 50% while plugged in, then this causes extra wear to the battery.

Answer:ThinkPad Edge 13 - Battery Firmware update not working

Hi and welcome to the forum!

You need to have latest BIOS version (which is 1.20 6ZET...) and Power Management driver.
 
See below text:
 
"Lenovo has bundled the necessary dependencies and the battery firmware update into a common package. Customers who prefer to download a single file may download the appropriate package for their type of system. These "dependency wrapper" programs have the following basic procedure:
 

Check the Power Management driver version. Update if necesesary.
Get the current BIOS and embedded controller version.* This requires another driver, the Lenovo System Interface driver. If this driver is not present, version 1.02 (81vu13ww) will be installed. This driver is part of the "Hotkey Features Integration" package, but only the System Interface driver is installed.
If necessary, update BIOS to the minimum version supporting battery firmware update. A system reboot is required if the BIOS is updated. The battery firmware update will automatically continue after rebooting.
Update the battery firmware. A system shutdown is required after the battery firmware update. The system will not automatically turn back on after being shut down.

Please click here for more detailed operation of the dependency wrapper programs."
 
Hope this helps.

Hi all,

i'm useing a Toshiba *Tecra M4* model *PTM40E-01L01RGR* Bios version *3.5.*
From one day to another the battery is absolutely dead - this means battery time drops from about 2 hours to zero in one day.
Now the battery can not be chanrged any more - it looks as if there is none installed.
So no boot without power cord and if you unplug the cord the notebook is powered off immediately.

From my experience if battery uptime becomes slowly shorter and shorter the battery is old or fails. But if it has no function from one day to another i would say this is a typical firmware or bios problem.

Is there any firmware or bios update available for the Tecra M4 (support page sais no - latest is 3.5 as installed ) or is there a fix or workaround i can use to get the battery back to live ?

Thanks for help !

Michael

Answer:Tecra M4 - Battery dead - Is it a BIOS or firmware issue?

Hello

On the Toshiba website you can check if a BIOS is available or not:
http://eu.computers.toshiba-europe.com/ => Support & Downloads => Download Drivers

But I doubt that the problem is related by the BIOS. In my opinion it?s a battery or mainboard issue. If you go to an authorized service provider the technicians can check your notebook.

And I don?t know what firmware you want to update. Firmware update is only possible on HDD?s and CD/DVD drives.

Get a messagebox saying "battery not detected" and it's not charging from mains. So laptop has now turned into a desktop... as needs plugging in continually... making it almost useless for purpose. This happened exactly after firmware update a few weeks ago. By coincidence the management software also kindly informed me that it could manage the battery better and stop it wearing out by only charging up to 90% - fair enough, but don't treat me like a muppet and disable it without any way to get it back. Tons of Windows 10 updates today (after not being able to use it for a few weeks) but still no battery. I tried F1 BIOS but nothing there to enable the battery (only to disable it). This is frankly a joke - timing shows it's due to the firmware update because the battery was fine and lasted a couple of hours right before. In 25 years of countless laptops, have never had this problem - batteries weaken gradually but don't suddenly lock up and require a paid replacement suddenly. How do we run down our original battery properly before polluting the planet? Phil

Dear Lenovo, After perusing the recent 2016/2017 comments by multiple users on similar posts about Ideapad Z510 battery from across locations/countries - it appears that the firmware that you had issued last year - has somehow got overwritten / superceded maybe in either late 2016  or early 2017 by some more recent/latest updates. I am writing from India and facing the same probem that the battery is showing 100% and then going off almost immediately. This probem had fortunately got solved last year when you had issued a firmware update - but now when i am trying to use the same files again - it basically conveys that "no battery available to update" because that particular firmware is already applied on our laptop. Hence, can you please release newer firmware update for this same issue -  using a z510 system having current till-date updates for different OS - win 7 / 8 / 8.1 / 10 - same way as you have released for thinkpad series of laptops too on the weblink - http://support.lenovo.com/in/en/downloads/ds001322 Come to think of it - that if a fully working battery is being "prompted" as weak and "need to buy" - but actually is a fully functioning hardware - isnt it a bit of a letdown for your users??? - what to say of  some who might have already bought and replaced with newer replacement batteries - which is actually a completely avoidable cost?

I just this evening bought a brand-spanking new Netgear WGT624 802.11g router, with the "Super G" PC Card to go along with it.

Took me a while to get the router working in regular wired mode (had to reset the modem, then everything was peachy). I noticed on the auto-update firmware screen that the loaded version was 1.x, and the newest was 3.x. "Heck, that's pretty old!" I thought, so I decided to update.

It then hung on "Updating settings." It's been dead since.

Every time I try to ipconfig /renew, my system tray notifies me that a cable is unplugged. (This happens on multiple computers.) Wireless is a no-go. And I've tried to do a hard reset to no avail--unplugging for 30+ minutes and trying; unplugging, holding down reset, then plugging in while still holding down reset for 20+ seconds; hold reset, unplug, keep holding, replug.

My last course of action is to return the product tomorrow morning. But before I do, is there anything I can do to try to fix this?

I have a T61 with a 9 cell battery with 66 cycles on it. I ran the battery maintenance application on the battery. That ended (after 30 minutes or so) with the system shutting down (even with power applied) and the battery showing the dreaded blinking orange light. I know the battery was not as good as it was when new, but it did work. Now I have nothing. I think it stinks that the maintenace tool killed an otherwise usable battery. There are numerious posts here and other website that these batteries may not really be unservicable, just that some threshold was exceeded, perhaps briefly, or the threshold was lower that it should have been. Last summer a friend, with a T60, had the battery fail with an orange blinking light too. Lenovo really needs to get their act together on these crappy batteries. You can't say that this is just a Li Ion thing as I have and know other that have Li Ion batteries in their cell phones that have waaaay more than 66 cycles and a few years on them that work fine..... My cel phone has well over 1000 cycles on it of varying depth of discharge.

Answer:Thinkvantage battery maintenance killed my battery

It sounds like something unrelated (to the battery) may have caused your system to crash, perhaps interrupting the process, but it's hard to say. Have you tried charging the battery for 12hours with the system powered off?   Before lenovo offered the automated battery reset option, I used to run the battery down as close to 0% as possible, then boot to bios and wait until it would shut off (virtually no charge at all), then charge for 12 hours. It was sometimes a futile effort, but other times would end up with a useable battery. In general, I've been pretty happy with the quality of Lenovo batteries, but not with the price. If the Chinese can make knock-offs containing the same brand of cells and ship them to the usa less then $30, then there is no reason a lenovo battery should cost 4-5 times as much, but since I rarely use my thinkpads without ac power, it's mostly a non-issue with me. I only need enough battery to protect on power outtages and if I want to relocate my thinkpad, and even a weak battery can handle that. I hope you're able to salvage some life from yours.

Was hoping to have some help with resolving my problem.

Over the past few weeks, I have noticed that the trackpad on my XPS 9550 (2015) has been rising, especially in the bottom right-hand corner.  At first it only rose a very negligible amount but now the corner has noticeably risen and both left- and right-click do not register.  If the laptop remains turned on for more than a couple hours the trackpad rises even higher though not as much as I've seen happen to other owners'.  I haven't used the laptop in over a week now in the hopes of avoiding any other issues that may arise.
From what I've read, this is a common problem due to a bulging battery and should be remedied as soon as possible.  For this, I have a few questions:
-Should I be worried about permanent trackpad/case damage?  Some owners have stated that at a certain point the trackpad will become damaged and must be replaced.
-Is the battery a safety issue?  I have the laptop on to make this post but I am worried about turning it on at all.
-What are my options for resolving this issue?  My laptop is out of warranty so I am unsure as to what the procedure would be for replacing the battery.

Any help would be greatly appreciated. Thank you.

Answer:XPS 9550 (2015) - Battery bulging, pushing up trackpad

-Should I be worried about permanent trackpad/case damage?  Some owners have stated that at a certain point the trackpad will become damaged and must be replaced.
Yes, remove the battery ASAP. The laptop may work without it on AC power.
-Is the battery a safety issue?  I have the laptop on to make this post but I am worried about turning it on at all.
Yes, it is a moderate fire hazard, may start burning if punched, and it should be handled with extreme care. Funnily, this is not stated in any safety warning in the service manual, perhaps because the batteries were in fact not expected to swell.
-What are my options for resolving this issue?  My laptop is out of warranty so I am unsure as to what the procedure would be for replacing the battery.
Faded capacity is considered normal wear and may not be covered by warranty. I believe swollen batteries, especially soon after warranty expiry, should not be considered something normal and should be fixed for free by the manufacturer with a recall even after warranty is expired, particularly because they may damage other components and because they are a fire hazard. Some buyers have reported that Dell did that for them, but this seems to depend on the particular case and Dell centre.

Hi all! As written in the topic I have a huge problem with the run-on-battery-management of my X301-System + Windows 7 SP1. I replaced the optical drive with a secondary battery (ultrabay). Both batteries were identified by the system and charged to 100%.But when I run the system on battery, the system only uses the second battery. So if it runs down, the system turns into suspend/hibernate mode even if the primary battery is charged to 100%.Why doesn't the system switch automatically to the primary battery, when the second one is empty? As long as the second battery is down, the system also won't start/resume from the suspend/hibernate mode. Does anyone know this problem? Is there a known solution for that problem?

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.

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 (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 have a T61, bought 10/07.  I got this message out of the blue after i unplugged my laptop and it shut itself off.  Only turns back on when plugged in.  The orange battery light is flashing despite it saying the battery is fully charged, i called lenovo and they said i need to purchace a new battery, since the 1 year warranty exprired just over one month ago (convenient for them).  I have searched and found that this is not a new problem with lenovo and that 2 sets of recalls on the t60 battery occured recently, but mine apparently does not quailfy for recall (already checked).   The battery info says its a sanyo battery with poor quality, 44 cycles, first used 10/07.I'm kind of peeved that i'm being told i need to buy a $115 battery just over a year after getting this computer, and believe lenovo should step up for clearly something being wrong with their system as i'm in good company of others with this problem. anyone have any ideas?  do i really need to purchase a new battery??thanks for any help

I've set the Battery 1 (Main battery) thresholds to 45%~90%, which works very well. Below 45%, start charging, battery level to 90%, stop charging.But I also set the Battery 2 (Keyboard battery) thresholds,(50%~95%) it doesn't work. It will always start charging when battery level below 96% and stop at full. The thresholds is not working. My Helix is running Windows 8.1 with all the newest drivers and necessory software supplied by Lenovo. And after installed the Settings Dependency Package and Power Management Driver, I installed the previous version of Power Manager 6.64.2 in order to set the thresholds. SO, HOW TO SOLVE THE THRESHOLDS-NOT-WORKING ON BATTREY 2?

Hi guys. I have a T470 and after the latest Windows update I encountered a battery naming issue. Before the update batteries had proper order and were named accordingly: battery 1, battery 2, no surprises here. But after the update I noticed the order has changed to battery 0, battery 1 (attached pic below) Yeah yeah, I understand arrays start at zero but what is that? I was just wondering is it just me or you guys have the same situation going on with your batteries? Is there a way to change the order back to "normal"? .

Are you using genuine Lenovo brand?  Is the power manager telling you when the manufacture date and cycle count are?  Try downloading the newest power manager from the website.

I recently bought a Lenovo Thinkpad X220. However, after only 1 week use, i receive the error "The battery cannot be charged. Replace the battery." In particular the battery meter indicates 48%, however when I remove the a/c the laptop immediately shut downs. The problem occured after only 3 charging cycles, when i upgraded the firmware to the 1.19 version and installed the lenovo's power management software. However, i cannot correlate the 2 events for sure. I tried to get back to a previous version, re-install (or remove) the power management software, however the problem persists. Any suggestions?Thanks in advance

Answer:X220 battery problem: "The battery cannot be charged. Replace the battery".

Hi, I already had this problem on my X300, and the battery was basically dead. You need to replace it. Probably yours was defective. In my X300 it had append after 9 months only.

Hey, I really need help. I'm having problems with my laptop. It's a dell inspiron 7559 and was bought around January. Recently I have seen that the battery has no longer been as hot as it used to be when I first started using it. Along with the sleeve on the tip of the screen power adapter (below the part where the adapter lights up) has started to come off, exposing the wires. The battery has continually dropped down its percentage rate ever since I bought it, and it won't go back up. It is currently at 0% battery life and it says when you highlight over the battery icon ( plugged in, not charging). It also happens to show the BIO setup when I start the computer and shows that the batteries wattage and type cannot be determined. In the BIOS setup, the ac adapter type is unknown. The battery has not been through any harsh conditions along with the laptop. I have tried removing the battery, starting up the computer with the ac adapter (which is 130 watts), then adding the battery back, and ac adapter, then turning it on, but it had no effects. If I remove my ac adapter while my computer is on ,it instantly turns off. If someone can support me with this issue, it would be gladly appreciated. Thanks.

Answer:Laptop battery not charging, battery not identified, 0% battery life

It sounds likely the charge circuit on the mainboard is damaged.  Contact Dell to have the mainboard replaced under warranty.

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.

My S430 is running Win 7 Pro. Until yesterday it was functioning fine. Yesterday it shut down when the battery ran out with the Windows 'Critical Battery Issue' message. It was closed and was meant to be in Sleep mode.  After charging overnight 10+ hours the Windows battery meter says that the battery is at 0%. The Lenovo battery meter says that it is at 0%.  Clearly, it should have fully recharged by now. I have tried restarting the laptop etc. with no change.  So now either the battery is not charging, or, both meters are reading it wrongly. How can I resolve this problem?

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  

Answer:l520 orange battery indicator blinking while battery full according to power management

hey bert520,would it possible for you to use your L520 with the battery only until it fully discharges? Once it has fully discharged, charge it back to full and during this point just charge it, do not use it.When it is completed, check if it still happens.Also could you go to http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-77172and download the latest Power Management software and drivers from here and do an update.

Hi all,
I've owned my Lumia 920 for 3 years now, purchased brand new and always looked after it. I've had no issues until yesterday, except for about 2 months ago the side-camera button stopped working to load the camera app and take photos (app tile and on-screen capture button now).
The night before last, I put my phone on charge whilst I went to sleep and when I woke up in the morning I found that the battery was showing as being in saver mode. I thought the lead had come loose so I let it charge again and confirmed it had the charge icon. When I took out the lead 30 mins later it had even less charge.
I thought the phone might just be going screwy so I did a soft reset (held volume down and power until the screen went off, and then the phone vibrated and reset). When the phone came back to life, it had 100% power.
Within 3 hours I was down to about 50% when it had just been sat on the desk, idle, next to me. I turned the phone off and on again, and the battery life was back up to about 98%.

Hi everyone! Two days ago I've got a problem with my Lenovo S10-2 IdeaPad. The problem is that battery suddenly stopped working. When I'm trying to start my netbook just on battery nothing happens. No led lights, no fan sound, nothing. When I plug in AC adapter battery led light turns on for a moment on orange, then chanes to white and holds for 6 seconds, then blinks and holds white for other 6 seconds, then again for the third time and then turns off completely. When I press power on button with AC adapter pluged it and net book starts to boot, blinking with the same intervals for 3 times repeats.  My Windows XP shows seeing the battery, it shows 69% but I have suspicion that it isn't charging, cuz 2 days ago it was about 72%. I've googled for similar problems, tried to disable and uninstall Battery ACPI-compatible Microsoft manager. I tried to plug out AC adapter and battery and hold power button for 30 seconds, nothing helps. Any ideas that could help? They would be very much appreciated.

Can someone help me with this problem? So I just received my brand new Dell Inspiron 15 3000 and the battery is not charging. It says it's "Plugged In, Charging" but it never goes up and stays at 0%. At first I thought I just need to plug it in for several hours but it's been 5 hours now and still the battery stays at 0%. I tried running the BIOS Diagnostics just to see if there are problems and there's none. The battery status says everything is running normally and the Battery State says it's Idle. I tried draining the flea power several times, removing and reattaching the battery, but to no avail. I'm getting really frustrated and I'm really close to throwing this laptop back to Dell. 
I read somewhere that I have to update the BIOS but it won't update unless the battery is charged at least 10%. Someone also suggested that Windows 8.1 is causing the problem. I haven't even started using this laptop and it's already giving me a *** ton of problems. Any help would be much appreciated! Thanks guys! :)

Hi,
I have a Dell M5510 precision laptop for business.  Around January 2017, 7 months after owning this laptop the track pad started to come loose. At first I didnt know why, it was very minor, then each month it started to come off more and more. Around 2-3 months ago I stopped being able to use some of the functionality of the trackpad. I finally took the laptop apart to find out the battery had expanded and was causing this issue.  I purchased a M5510 with every upgrade (xeon, 4k, larger battery etc) and figured I would not have any issues as I use this for work. Has anyone else had similar issues on the M5510 Precision series?
It looks like the battery is very swollen in multiple cells and the trackpad looks like its about to blow right off the laptop.  
I'm also not sure how safe it is to use this laptop for business travel now that it looks like the cells are expanding and lithium ion explodes.

Answer:Dell M5510 battery breaking my trackpad and looks like its ready to explode (4gvgh battery)

So first thing is stop using the computer.  If the cells are expanding that could cause a safety issue.  I would call Dell ASAP and have them replace the battery which is obviously defective.

Hi ! I need help to determine if I just plug in the samsung evo850 drive with oxdygx cable, onto the motherboard, with the UEFI-bios ask me to initialize the evo850 dirve?  If yes, after format the evo850 as GPT, will the bios manage the 512g pcie ssd as C drive (with windows 10 in it) and evo850 as D drive (data disk)?  
Another question is whether hdd password can be managed by the uefi-bio just like the legacy bios?
Also whether a similiar hdd password can be used on 512 pcie ssd?  

Answer:newly purchase xps15-9550 pcie 512g ssd 84 wh battery - try to add evo 850 on to the hdd slot, take out the 84 wh battery

The initialization takes place under WIndows - NOT in setup.  UEFI will detect the drive, but you must use the disc manager to partition and format it.

Hopefully you realize you'll need to replace that 84 W-H battery with a 56 W-H unit (the drive needs the space occupied by the extra cells in the larger battery).
Your existing C drive will be unaltered - if you have no other drives attached, the new drive should show up as D>
You should be able to set a password on both drives -- that said, they're not of much security (they can be removed and once that's done, the data is open for access).  Effectively if you have a need for security, drive encryption (bitlocker if you have 10 Pro) is a much, much, much better idea.
Also be advised:  the hard drive password ties the drive to the system.  If for some reason the mainboard gets damaged, the data will not be accessible without the intervention of a data recovery/password removal service, so backups - of both drives -- are ESSENTIAL.

Hello wonderful Lenovo user's and guru's! I have recieved a Lenovo Ideapad y550 from a pawn shop. I grabbed it because I knew this was a pretty good computer. I thought I could fix any problems it has and it would be just fine. =] So this laptop shuts down instantly if I unplug the power cord. Just dies, no time to do any saving or lights to blink. Just instant shutdown. Also when I try to power it on when its unplugged from the AC, it does nothing. Also shuts off in the middle of playing guild wars 2. No other games shut off on me. When I realized I had this problem, I ordered a new battery for my model of laptop. The new battery is doing the exact same thing as the other battery that was in it. It seems the computer has a fresh install of windows except with a .old folder in the C drive. So I am guessing someone did some sort of reformat or recover? the recovery was done through the Pawn Shop. It seems that it has windows 7 64 bit.  Any help would be greatly appreciated!

My Compaq Presario c500 will not turn on when plugged int a/c power.  The indicator lights constantly blink or flicker,  If I unplug a/c and install a charged battery the indicator lights glow constant an the machine will boot on.  If I then plug in the a/c power, the machine will function properly as long as the battery has a charge.  The charge does not run down as fast when the a/c is plugged in as it does when operating on battery alone.  I have changed the hard drive, ram and power jack, checked for driver updates and current BIOS all to no avail.  Short of trashing the motherboard, is there anything else I can do to try to resolve this problem?  I have heard o several otters having the same problem wit their C500 and one person with the same or a similar problem with a Toshiba L305.

Answer:Compaq Presario c500 as, hhd, battery light blink constantly w/o good battery

Sounds like power supply is weak if it cant keep up with draw to keep laptop running. The boot with power supply attached and having problems sure sounds like a weak power supply. Do you have a meter available to measure the voltage under load to make sure its stabile and not pulsing or too low? Or a second power supply adapter to eliminate this?

Hoping this problem will be noticed by more people, the original post on this issue came from:https://forums.lenovo.com/t5/Linux-Discussion/T470-Linux-Power-Bridge-wrong-discharge-order/td-p/365...https://www.reddit.com/r/thinkpad/comments/63odjr/t470_battery_order_question_internal_discharges/ Brief description: same problem with OS including Win 10, Ubuntu 16.04, Gentoo etc. The internal battery always gets discharged first regardless its remaining power, which is generally harmless but seems not so good for the internal battery life. With my own T470 machine, updated with the latest 1.29 BIOS, this problem remains. According to searching results online, this little bug came with early versions of X's and T' including T460. PS: this issue had been successfully fixed with T460 via BIOS update 1.26, hoping it would be fixed with T470 sooner or later. Best regards. 

Answer:T470 power bridge wired battery discharging order, always internal battery first

I see the same behavior here.  We will check it.
