Battery Firmware Update Disconnected Battery on Z400 Touch, Now Won't Charge

Q: Battery Firmware Update Disconnected Battery on Z400 Touch, Now Won't Charge

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!

Hello Lenovo Community!I own an Ideappad Z400 Touch and I had issues with trying to charge it. Obviously I turned to the forums here and I found a possible solution here. When I tried to perform a battery firmware update, it went smoothly and then suddenly turned off and had a fast flashing orange light. Obviously I knew my battery and/or charger let me down in the middle of the process. I'm kind of scared because I don't know what to do nor have the money to afford a new laptop. What most likely happened to the battery is that it got "electronically disconnected" and technically only relies on the AC adapter which now I have found out is pretty screwed up and stops charging once Windows actually boots up. Is there any way to fix this? Please help! Thank you and have a wonderful evening!

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.

I have two Lenovo Y40-70 computers that I purchased within a couple weeks of each other.  They came with Windows 8.1 but I upgraded to Windows 10. A few months ago, I noticed that my computer battery meter was reading 100% for an hour.  I continued to work unplugged until the battery died while still reading 100%.  I recharged and the battery again read 100% for more than a couple hours, then died.  So the battery lifetime is as good as always, but the reading is not right.  When I reboot, it still reads 100%. Strangely, the second system, whcih I had not used for a while, was OK, but a few days later, it started doing the same thing (though it was reading 87%, the charge when the computer last worked right.  I suscpect that this happened after a critical update, which the second system went through later. Recently, I downloaded from the Lenovo website the newer power management software on both computers, and it did not help. Then I noticed the Battery recall so downloaded the "Lenovo Battery Utility 2015" to see if my system was afffected by the problem.  When I run the utility, I get the mssage "No Battery Detect."  So it would appear that there may be an issue with the software detecting the batter. Since I can't know the state of the battery (it appears to not want to recharge until it's empty, I gues because it thinks it's 100% charged), I cannot count on this computer when it's not plugged in. Now I ...

A:Ideapad Z400, Z500, Z510 battery will not charge -...

Hi CuriousFox , 
 
Greetings.
 
To isolate fastest is to have another battery to use or charging the original battery on a known working compatible laptop.
The power checkout guide of the hardware machine manual provides steps to check battery charging integrity (example form Z510 manual page 21) .
 
You can also try plugging the laptop but not turning it on for 1-2 hours checking if there would be changes with the battery indicator LED.
 
Would it be the same using similar energy manager and operating system that came originally with the machine?
How is the battery health and battery report?
 
Update us how it goes.

Hello. First of all, thank you for taking the time to view my post and potentially help me out. So the problem is that my laptop will not start. I was using my laptop here one day and it was working fine, but it was unable to charge for some reason and ended up shutting down so I went to bed. The next morning I tried turning it on, but it was dead. I have tried a different charger as my sister also has a lenovo laptop, but this did not work either. I would think if the battery was the problem, the laptop should still be working with the charger in? I have tried calling support line several times with no answer, the warranty has gone out and I forgot where i bought the laptop sadly. Really frustrated over here, and any help is highly appreciated!

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!

How can I get a new battery for my 15-p157 notebook?Hi I bought my laptop in September 2017 from Currys, they have washed their hands of it as it is a battery fault. I'm sure the battery should last longer than 5/6months. Now it just says plugged in not charging/replace battery. I checked my battery against the recall list, it tells me I'm unaffected and to continue using it. However it does not function at all, the battery gets extremely hot (burnt my fingers twice) when plugged in to mains, however I have to use the mains to power my laptop as it switches off. I have so far had no reply from support which is irritating to say the least.I am aware batteries are a consumable, however this laptop is only plugged in when it needed to charge and then ran on battery, I have tried atx reset (disconnect all power, hold button for 45-60 seconds) no joy. This all happened over night, shut down my laptop the night before, next day nothing. I even bought a brand new charger for it. Looking in hp store you don't stock a battery for my laptop. How do I get this replaced? It's a v104 battery. I'd rather not have the whole laptop changed as it's perfect for me, just the battery that needs replacing.If anyone can please just point me in the right direction that would be fantastic.Kind regardsTraceySmitht29

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

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.....

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?

Hello.
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...

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

 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

Hi there,
I think that my netbook (Toshiba NB550D-111, Win7 Starter) may have powered off during Windows Update as now it will not get past the green loading bar with "Microsoft Corporation" underneath. It gives an option to start Windows normally or to load repair files but both end up stuck on the green loading bar. Safe mode (all options) gets as far as classpnp.sys then freezes.

Using a different laptop I made a Window Repair Disk and then copied the files over the a USB (netbook has no CD Drive) as per the online guides. When the USB is booted the repair files load, there is a blinking cursor then it's back into the green loading bar. Safe mode (all options) gets stuck on disk.sys with the USB inserted.

Found some threads with similar symptoms with most being caused by a dodgy HD connection (checked, nothing obviously disconnected) or the wrong SATA mode selected in the BIOS (seems to make no difference between ACHI or Compatible). I then tried a live Linux USB to replace the classpnp.sys file with another from a working (different specs) laptop, this led to the same results.

I have not waited longer than 15 min at the green loading bar and I don't have any installations disks. If anyone has experienced this before or can give any pointers they'd be greatly appreciated, thanks.

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!

With no more power since it is ram the firmware is gone.In any case, I am afraid to buy new battery to get same problem since it is old computer. I have found that there is a lenovo utility for firmware utility but my computer is not in the list. Can I try or there is another solution. Only solution out of firmware update is buy a used working battery and replace with the one I have taking care to keep power during replacement (this is quite touchy). I thought may be to use a similar battery as Thinkpad X61 and just change the case. Maybe there is another third part solution. I hope this information and my experience could be also helpfull to remember others to charge your battery once in a while ... Read more

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?

I tried to install a battery  update on my Lenovo T520.  The update fails with an "internal error" message being reported.  The battery does not fully charge and now lasts only a few minutes once the charger is unplugged.  The battery is a Lenovo replacement less then a year old.

My X230 with 6 cell 44+ battery was working good. Earlier this week, lenovo system update suggested a battery firmware update and I clicked and updated. After the update, the battery is completely dead. Don't understand how this can happen. Anybody has any ideas? This is the original battery and has been working good and still holds about 2 hours charges before its sudden death.

I am using a non genuie battery in a X220 without any problems. Now I want to make a Firmware-Update from 1.28 to 1.43. Do I have to expect that the non-genuie battery with firmware 1.43 may no longer be charged?

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.

A:Battery Firmware Update has killed Brand New E420 ...

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.

A:The tool was unable to update the battery firmware due to an internal error

Hello MadsWilliam, welcome to the Community,
 
Exactly which systems are you seeing this on please, the 20DA and which other types please? Could you also check the manufacture dates on a couple of examples in case they may be newer than the firmware updater and therefore not recognized by it and also, it would be helpful, if you could let us know the BIOS version from an example of each MT which is presenting you with the error please?
 
Thanks
