Preferred Solution: Genuine battery will not charge - T430

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.

Hey Lenovo Forum:
I'm having a battery charging problem that seems slightly different from any on this forum so far. I just acquired a T430 running Windows 7 (64-bit) like a charm. After a few issues with the audio drivers, everything has been running smoothly. 
Abruptly, yesterday, when I plugged it into the wall socket (the same socket that it had sucessfully charged on earlier) it failed to charge. Thinking it was the outlet, I tested it. The outlet and adapter are both working fine (the adapter powers the computer no problem with the battery removed from the system). The lock switch on the battery is in the propper position (i've tried both). The battery is not overheated (it's cool to the touch). I tried removing everything and holding the power button (apparently that discharges some built up charge in the system) then reconnecting the battery and AC adapter, nothing. 
I just downloaded the power manager which (when the laptop is, in fact, running off of AC power (the battery charge indicator hasn't draining in hours of continuous use) reads:

HiIs your laptop model T430 or Z400 as in the thread title?Is the battery new, from official Lenovo store or 3rd party store?

I have received a new OEM 6-cell battery for my T430 2344-DAG running Windows 10, OS and system fully updated. I find contradictory advice about the recommended first charge routine: charge for 24 hours, do three deep cycles, reset battery gauge, or alternatively don't do any of these actions. I would greatly appreciate advice on the current recommendations.

Hello Apologies if someone has already posted this query and got a response. My G700 has Lenovo's Energy Management software ( installed. Until recently, the battery would charge (and drain) as expected - it is the original that came with the laptop a few weeks ago. I'm running Windows 8 and haven't upgraded to 8.1 yet. However, now I get a pop-up box from the software every time I boot up from saying that "the system does not support batteries that are not genuine Lenovo-made or authorized.....". Also, the software is preventing the battery from being charged, so I'm having to use the mains power. Lenovo's support has suggested that it might be a (physical) problem with the battery, but it seems to be a software-related. Please can someone help with this one? Is there an update to the software that I can install? Can it be disabled to allow the battery to be charged? Does the problem go away with an upgrade to Windows 8.1?  Thanks in advance!

A:G700 - Energy Management says battery is not genuine and won't charge it!

Hi Ammo23,
Welcome to Lenovo Community Forums!
    This error may be a Software/Firmware Related or the battery is really bad and being read as not genuine.
can you try Doing this,
 1. Try Performing a power Drain and BIOs Reset.

Remove the AC adapter and the battery, Now Hold Down the power Button for at least 10 sec. This will drain the Mainboard.
Reconnect the Ac and Battery and Turn on the system,Right away start tapping F2 to boot into BIOS Setting.
Hit F9 to Load defaults and enter for Yes then hit F10 To save and Exit then Enter for Yes.

 2. When Booted Back up to Windows,
              Open Device Manager and under Battery Look for Microsoft ACPI Compliant Control method Battery
              Right Click On it and uninstall it, Restart after uninstallation.
Check if the issue will be the same after the Steps.
       If still the same, Uninstall the Lenovo Energy Management from Control Panel / Programs and restart the system.
         check if the system will charge without the Energy Management Software,
  If the same thing happened I would Suggest you call Lenovo Support right away and report the steps your did and still getting the same result.
Let me know your Findings

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!

Hello fellow techies,
I have a situation with my Compaq Evo N600c battery or something in that directions, so I need possible solutions. My laptop needs to be plugged in at all times, which makes it frustrating because its a portable laptop. If it becomes unplugged the laptop will turn off within 10 seconds flat. I fear that this will, if it hasnt already done so, mess up my electric circuits among other components. Can any of you suggest or recommend options I can use to diagnose the situation. I would like to find out what the problem is, whether I should buy a new battery or some component or prong that I need to replace? Thanks for the feed back!


A:Battery will not charge or hold charge?!?!

Yup, sounds like a battery problem.

First, make sure the battery has a charge. Most laptop batteries have a button on them somewhere you can push that will give you the power level. Alternativly, there should be a utility in windows or the BIOS that will allow you to check the power level.

If the battery has no charge and isn't charging, then replace it with a known good one and see if it will charge up when the laptop is plugged in.

If the good battery won't charge up, then there is a problem with your motherboard.

If the battery has charge but won't power the system, then there is a problem with your motherboard too.

If this is the case, then the best you can do is contact the laptop manufacturer and get them to replace the motherboard.

Hello, Lenovo Community, I recently tried updating my battery's firmware. It was going smoothly for about one minute until my charger disconnected and my laptop's battery died and will not charge. My charger has a long history of automatically disconnecting (two blinking lights, one white and one orange) so I cannot power my laptop through the charger itself. I really don't want to get the port checked, so I am looking to see if there are any other ideas from the community.  Here is what's happening:-My charger disconnects everytime I try to boot now (used to disconnect before loading Windows 10)-My battery is disconnected from the system (electronically, not physically probably)-I really cannot power on the system.  Thank you, Lenovo Community!

Just received a new Dell battery for my laptop.  The battery icon starts out at 100% and time remaining at about 3. 5 hours left, then within 1 minute the time remaining levels off to about 2 hours left.  The battery showing time remaining is jumping up and down.  I am only using the computer for the internet.  No CD or DVD or gaming.  At best I get 1.5 hours out of a charge.  Is this normal?  Or did Dell send me a bad battery?

I have an XPS 9550 6th Gen running Windows 10 (Just over 1 year, out of warranty).
The issue is when the charge plug is plugged in and hovering over the battery icon it says that battery is charging.  However the battery is not charging but discharging until the laptop switches off.  The only way for the battery to charge again is to deplete the battery until the laptop is unresponsive when the power button is pushed to switch lap top on.  Once there is no residual power in the battery it will start charging again to 100% after which the cycle repeats, discharge.
Things I have tried.
Latest Bios update - no change
Another A/C charger - worked ok for a few days
Replaced battery - no change
Bios settings - reset to default (info related to battery and A/C charge reports all good)
F12 - Dell diagnostics, reports all good
When Battery is disconnected the laptop works normally
The laptop charge socket seems tight and secure
I have searched the internet exhaustively but have not found this same issue reported.  The only feasible way I can use the laptop is to disconnect the battery.
Can anyone suggest anything?
I would also like to disable the battery instead of having to open it up to disconnect, is this possible?
Any help would be much appreciated, thanks

I am dual booting Windows 10 and Linux (Ubuntu 17.10). I was on Windows 10 when I was updating my battery firmware using the Lenovo Battery Firmware Update Tool. It prompted me to update my battery and I confirmed and clicked next. Immediately, my screen turned black. I waited 10 minutes and then did a force shutdown on the computer by holding the power button. Now my battery won't charge. It is an official 55+ Lenovo battery and last week Ubuntu's acpi said that the battery was at 67% capacity and could run on battery for an hour and a half at full charge. Now all of a sudden, after the failed firmware update, my battery will not charge: whether the laptop is on in Windows 10, on in Ubuntu, or while the computer is turned off and plugged. When I do connect the AC cord the battery indicator blinks with a steady green, to a stready orange, to a rapid orange, and then off within a span of ~10 seconds. I have tried deleting the battery drivers on Windows and restarting and it does not work. I have also tried to update the battery firmware again using the Lenovo Update Firmware Tool but it repeatedly gives me the same error "The tool was unable to update the battery firmware due to an internal error." I have also updated to the latest BIOS to no avail.

Ok this might be easy..it might not (COMPAQ M2105)

I ended up replacing my motherboard for a model with more features (SD readers blah blah).

I took it all apart and put it all back with the new board in...now when i go into windows (and even before while booting)...the orange lights would come on for a second...then beging to flicker

while in windows...it just will either not charge the battery..or flicker from AC to battery

i CAN power the unit on with the battery alone, and i CAN power the unit with the cord alone...

lastly, my old motherboard (which had a HD connector problem)...still WILL charge the battery...so i'm sure its not the battery...i don't think...

i also dont' think its the AC adapter since it is the same piece I used on both motherboards.....

what to do................

A:compaq M2105 laptop - battery will not charge, flickers from AC/battery

Hopefully you are experienced in working on and repairing laptops/notebooks... and you carefully handeled the replacement motherboard and didn't damage it. Repairing laptops takes considerable skill and caution.

It does sound like the "new" motherboard is bad unfortunately. How did you handle the "old" operating system restore to the "new" motherboard?

I've been using a Dell inspiron 1545 from about 3 years now and exactly after 2 years of my buy, the battery failed and it started showing me to replace the battery and always notified me about contacting dell for a new battery.
I didn't take this of much concern so i just ignored the message and kept on using my battery with my adapter plugged in. After 4-5 months of such usage, My battery completely failed and doesn't even offer me even a minute of backup, when i remove the power socket. Then i realized the importance of a new battery and then bought a new battery from Dell.
Its the same battery with the same specs and also the same family type. After i removed my defected battery, I replaced my new bought Dell battery and realized that my battery is working fine. its charging well but at some time, it says "Plugged in, But not charging" Which is rare for any new battery, which is bought brand new.

This is how it looks now after i remove the AC adapter plug and when i depend on the battery backup. it is providing me a backup, but I see a yellow exclamatory mark beside it. Which I think should not be present. it also says "Low battery" when there's already 99% of battery left!
I've also followed some online steps
1) updated by BIOS to the latest  2) Followed some other steps like uninstalling the battery ACI in the device manager and etc...

A:Bought a new dell battery and still my laptop battery doesn't charge!

Hi Utkarsh. I Actually FIXED this problem months back. and I exactly want to help you on this so that you can fix it yourself too..
the problem which is creating your battery to show an exclamatory mark is your power settings.
so follow these steps to get rid of that sign and a perfectly working battery.
1) Click on your battery icon (left click) you should see an option called " More power options" at the bottom of the popup.
click "More power options"
2) Now you will be taken to your control panel where you can see all of your power plans and under each plan, you will see an option called "Change plan settings"
3) Click on "Change plan settings" for your active power plan. Now you will get redirected to another control panel window, where you can see two kind of power options to get adjusted. that is, when you battery is plugged and when your battery is unplugged.
4) Don't touch those options, just click on "Change advanced power settings" at the bottom left of that window. THIS IS THE AREA WHERE WE NEED TO FIX!
5)After you click on "Change advanced power setttings", you will see a POWER options popup, go to the bottom and then you can see something called "Battery" with a plus sign on the left. click it.
6) Now you just have to change the levels for the following values
                   --> Critical battery level ( you can change it to 10%)

This is a bizarre problem I think.  My Lenovo P50 laptop will charge when turned off and plugged in.  But when I turn it on, it's running just off battery and therefore discharges rather rapidly (1-2 hours).  It does NOT say "Plugged in but not charging". It just shows that it's running off battery.  Additionally, there is no light on where plug goes in.  If I power down, sure enough light comes on and if I leave it for a few hours and boot up, it's back to 100%.  But then of course, it slowly discharges.   What the heck is going on? Thanks,Dave

A:Laptop battery will charge when computer is off, but when I boot up, it runs off battery only

Check to make sure your laptop is not in Airplane mode, because that would cause that behavior.     Check in two places, one under Windows 10's Action center (Icon to the right of Time in taskbar) and using Lenovo Vantage.     It could also be set in Lenovo Settings if you have that installed as well.  Lenovo Vantagehttps://vantage.lenovo.com/  Edit:    would uncheck "Enable auto detection" as well. Cheers,

 My G700 has had this issue recognizing its own OEM battery since I got it, and there is a long drawn out way of trying to resolve this, but the core problem I believe is that when the battery is Fully Drained it can't Self Identify as an OEM battery, so the laptop won't charge it.  Without charge, it will never get out of this state. Problem:  Battery not recognized correctly as OEM, so won't chargeFix:  Charge battery at least a little bit Yes, I know it won't charge, so how do you perform fix? Plug into power and take battery in and out 5-10 times, leave battery in and remove and replug power cord in side of laptop 5-10 times.  Then leave for 15 minutes, then boot normally. Battery will now be recognized!  Why because you managed to get just enough juice in there while trying to identify the battery 10x or so, for the battery to be able to successfully identify itself when you did start it up. This is a HACK fix, but way better than uninstalling, reinstalling power software, BIOS software and device drivers a number of times (which does not work all that well, I have found). Hope this helps you, let me know! OHHH, and keep your battery charged at least a little to prevent this from happening, and turn power off when not using.  I am not sure if this is just some faulty batteries or all batteries, let me know if other batteries behave better than mine. Best,Mark Eckdahl

Once my laptop fully discharged, at first it would not turn back on for about 5-10minutes before I pulled the battery and put it back in. From there, turned on the laptop, the battery charged to the maximum capcity and after that, the battery would no longer charge.Currently, I just have my charger plugged in without a battery. Did anyone else have similar problems? Help!

Hi Guys,

I get this error message.
"The AC power adapter type cannot be determined
Battery may not charge.
This problem might be solved by:
Connect a Dell 65W AC adapter or higher."

But I am using a 65W Dell Adapter that I got with my laptop.
BTW, I tried the steps for disc AC >> Start>>Uninstall MS ACPI >> Insert battery>> Restart. This process did not yield any favorable results.

HP g6-1b60us Notebook PCHere is the situation and symptoms. Battery not charging. Battery icon indicates battery being charged, but it sits at 5%. Have bought a replacement HP battery and that battery will not charge also (it sits at 50%, which I assume is the initial charge it came with). Run the HP Support Assistant and both batteries fail the test saying that cell 4 is bad (cells 1 to 3 have charge, but cell 4 has a 0 reading, even in the new battery). (Is there a problem accessing/charging cell 4?)When the battery is installed and the AC adaptor is unplugged, and the laptop is turned off, the battery charge LED shows a white LED (red/amber indicates that it is charging the battery); now the only time the LED goes out is when the battery is physically removed. Before the problem began, the battery charge LED would be off when the battery was installed and the charger was not being used. Now the battery charge LED goes off only when the battery is physically removed.What I have tried:Cleaned the contacts.Bought a new HP battery.Tried the complete discharge method of turning the laptop off, removing the power cord and battery and holding the power on key for over 30 seconds.Have done safe restarts.Reset to HP recommended settings.Suggestions/recommendations?

My battery all of a sudden won't charge. The computer works with remaining battery (when AC is not plugged in). The computer works with the battery removed when plugged in. But if battery is in and the computer is plugged into the outlet, it does not charge the battery, nor does it recognize that it is plugged in. It only tries to run on the remaining battery. WHen the battery is in and the computer is using the AC adapter, I get a blinking white light next to the plug for the AC adapter. I have two separate batteries, and it is doing the same thing on both batteries. I have tried deleting the  Microsoft ACPI-Compliant Control Method Battery and the Microsoft AC Adapter in the Device Manager section. It didn't fix my problem. I also used HP Support Assistant's HP Battery Check diagnostic tool. It says my "battery is functioning correctly, but the AC adapter is not attached. To completely test your battery, please attache the AC Adapter." The strange thing is, my AC adapter is plugged in, but the computer thinks it is not attached. So it is not recognizing my AC adapter when the battery is in. But does recognize and use the AC adapter when the battery is removed.  Does anyone have any recommendations for a fix? Thank you!

I bought a "new old stock" battery for my T430. The Ebay seller had good feedback and a UK business address so I thought it would be genuine. I thought T430 batteries had a validation chip and that prevented fake batteries from working. When it arrived, I found that the full charge capacity was less than 100% and it had 6 charging cycles. I also saw that the bar code shown by the power manager software was different from the one printed on the battery. Also, the printed barcoce numbers seem to be in a different font from my other thinkpad batteries. I read that the manufacturinbg date is part of the barcode - does anybody know how to work it out? The charge is also very erratic. It will be showing 80% full one minute then go to zero! Does this sound like a fake battery or just one that hasn't been stored correctly> I emailed the seller but he hasn't got back to me yet.

I have a T430 that will not boot when the battery is in the laptop.  I thought this was a battery issue so I bought a replacement from Amazon and the problem went away for about 3 months.  Now the issue is back so I ended up buying a new battery directly from Lenovo just to make sure I was getting a good battery.  Last night I put the brand new battery in the laptop and again it will not boot with the battery in. To be clear.  The laptop works fine when it is either docked or plugged in with the battery not installed.  The problem is only when the battery is in the laptop.  It blinks once and then shuts right back down.  I know the battery is good since I bought the brand new one directly from Lenovo.   Any suggestions? Update - I noticed last night that when I try to start the laptop with the battery in but not plugged in it will not even blink.  When it is plugged in it will blink once and shut off right away.  Could it be a bad connection from the battery to the laptop somewhere?  It's a brand new battery.

Hello Guys,I got myself a T430, that runs fine while connected to the charger. However, when unplugged it immediately turns off. I suspected the battery to be dead, but I put it into a different shell and the battery is fully charged.I also checked if the power connector could be damaged, but then it wouldn't power the laptop and charge the battery. Also it's not the "battery connected, not charging issue". There are no issues, as long the machine is connected to the power cord.Any idea, which part might be casuising it, so I could look for a replacement? Also non-hw suggestions are welcome

I replaced a bad battery which had 90% wear level on it.  Ended up replacing it with a generic 70++ and was having this issue.  I have since returned it and replaced it with a brand new genuine 70++ but am STILL having this same issue.  Windows will randomly detect a "low power state" and force a sleep, the battery level randomly drops to a very low value even though the battery is FULLY charged.  This happens regardless if the AC power is plugged in or not.  First thing I did when I got both batteries was let it charge while laptop was off.  Booted up to windows and watched the battery charge level % via HWMonitor and checked the wear levels of course, being a new battery I'm expecting 0-1% which both showed out of the box.  Every once in a while I will see the charge level drop from 100% to between 1-6%, windows makes an alert sound and then sleeps the computer, this is super annoying and to combat it for now, I have set power options to not sleep when plugged in, but on battery, windows does not allow you to choose "Do Nothing", it must sleep, shutdown, or hibernate -- all 3 options of course are a headache to deal with if I'm actually using the laptop on battery... I can visually confirm via software that this is happening because HWMonitor has colums for CURRENT, MIN and MAX values.  Booting to a fresh state of windows with full charge on the battery, all 3 columns read 100% of course out the gate.  When I hear the a...

Hi,I have a t430 with a new 9 cell battery.  I usually have my thinkpad connected to a second screen and charging most of the time.  Will the constant charge ruin my battery.  My first battery didn't last very long.  If it does harm the battery, are their any tips on extending or preserving the battery?  Thanks

Hi, I work in a school where we quite a few Edge laptops, I recently bought a T430 as a replacement for a faulty edge laptop but the battery doesnt seem to be charging or registering. I've done the old trick of removing the drivers from Windows which worked for the Edge laptops when they had a similar issue. If I use the laptop on battery it works, if I plug the power in then it runs on the power but doesnt charge the battery. Strangley it did charge at some point but now the battery is dead... if I run it on the power and plug the battery in then it dies. The battery is 100% genuine (a 70+) one. I cant mix the batteries as the others are 25+ ones. I was hoping they might charge but they dont, I dont have any means of charging the 70+ battery. I've updated the bios, I did do a battery firmware test before the battery discharged and all the drivers are on.. I've tried it on Windows 7, 8 and now 10. Nothing works. Annoyingly the battery doens even charge when the laptop is off. i dont want to spend 60 on a new battery if the laptop is a dud. Any advice please?

Hi guys, I've had my HP Envy for just over 2 years now, and already gone through one charger due to fault, and have had this new charger for over a year now which has worked fine till now. It is a genuine charger and of the right power output as far as im aware (19.5V, 6.1A, 120W) but only now does my laptop greet me with a message saying along the lines of 'thanks for using hp parts, you'll need a higher capacity output' and now my laptop doesn't charge but is kept alive when plugged in. I've had so many issues with this laptop, it massively overheats, its massively slow, and the charge the battery holds has always been an issue, and I probably won't buy another HP.Is it the battery, charger, or something different altogether?Sorry for the rant but I hope someone can help. CheersAdam

My Lenovo T430 won't turn on. I am on an engineering trip in Liberia right now and am trying to get it working. It worked last night. I plugged it in when we had electricity last night and this morning, it is not turning on.  I unplugged the battery and AC adapter and drained the excess charge. It still did not turn on. However, when I put the battery back in and then plug in the AC adapter, the battery led blinks green 3 times, blinks a 4th long time, blinks once more and shuts off. The first three blinks could correspond to the normal AC battery status indicator. Thank you in advance for your help.
