The IdeaPad Z400, Z500, Z510, P400, and P500 systems contain a function which can electrically disconnect the battery. If the battery is in this state, when AC power is attached the system will operate but the battery will indicate "plugged in not charging" and will neither charge, nor power the system. If AC connection is unplugged, the system will power off.
Lenovo updated the firmware of newer batteries to change how this feature functions. Customers with existing systems who experience these symptoms should update the firmware on their battery.
Here is the link to download the firmware update directly from the Lenovo Forums for Z510 systems.
After you download and start the update, please ensure AC is connected to the system and proceed with the instructions as follows:
Click Next... the installer will check your current battery firmware level...
Click Next again... and check the box to apply the firmware to the primary battery...
Press Next again...
AC should be connected so you may ignore any advisory messages (if presented) that the battery needs to be at 80%. ( It is possible that your battery may be below 80% and you need this firmware update to resolve the no charge symptoms - just proceed by clicking next)
Press next...
Ensure AC is connected and click next...
The progress meter will display and update as the process completes...
Do not interrupt this process - Do not power off the system until complete.
Once the process is completed, click Finish.
Now, click this option to shutdown and then restart so that the firmware update will take effect.
If this update was applied proactively, there should be no noticable change in system operation. If this was applied in cases where the battery was in a state where it would neither charge nor discharge, after the update and reboot, normal charging operation should be restored.
Please Note: There are other possible causes for plugged in / not charging conditions including settings in Lenovo power manager. Please see this related article on that topic

Hi I bought a new Ideapad Y510p in December 2013, my laptop battery charges till 60% only after that it shows not charging. Help me.......
Hi, I bought Lenovo IdeaPad Z500 last September (2013) and have not used it for a while. some days ago I realized that the laptop works only when plugged. In other words, the battery is not charging and when I unplug the computer it stops working. before attempting to follow the instructions described above, my question is: if i download the firmware, will my warranty be recognized? Shall I first route my request of assistance to them and then, eventually, perform the update? Thank you.
My Lenovo Idea Pad windows 8 battery shows 74% available plugged in not charging If I unplug my power the computer shuts off.
my ideapad z400 is in windows 8.1 pro. i tried to download the firmware update but it is stucked at configuring the program. please help
Since I cannot log into the laptop, I can't download anything. Can you help?
When I'm running the update, I'm allways receiving the following message:
"The tool was unable to update the battery due to an internal error."
Any solution?
IF YOU ARE HAVING TROUBLE WITH THE BATTERY SAYING "PLUGGED IN, NOT CHARGING" THAN DOWNLOAD LENOVO ENERGY MANAGEMENT FOR YOUR PC AND OS AND FOLLOW THE PROMPTS!
Will this firmware fix work on the Z510 as well? I'm experiencing significant battery issues with my 9 month old Ideapad Z510.
All,
Newer production models likely ship with the firmware already applied. If you run the update and receive an error message that the battery does not require the update, then this is likely the case.
This KB does not address all possible reasons why the battery will not charge.
Bigboy61's comment above fairly notes that the power management settings may impact the battery operations. If customers have wiped the preload and installed a fresh copy of Windows, I would recommend they install the Lenovo energy manager.
Within some versions of energy manager, there are settings for battery health that may limit charging unless below 50-60%, resulting in plugged in but not charging messages.

I have a similiar problem with the 11 months old Z510. The battery percentage shown is wrong. Its showing me 99% all the time, and suddenly the laptop shuts down after 2,5-3 hours. ( of course without informing me that the battery is low) actually battery life is ok,only the percentage shown is wrong. Can u please help me? I tried to install the firmware update, but it is not working. I have windows 8.1.
Sir Mark,
does this work on Z410 as well? or is there another firmware update for newer versions? I only had my laptop for a year now, and my battery is not charging anymore.

I noticed the update on January 15, 2016. Our Lenovo Z500 Touch stopped charging and there are no lights. My daughter used it in class yesterday and plugged it in when she got low battery. It would not charge. We tried our second power adapter and no luck. It is completely dead, so I can no longer do the firmware update. Any suggestions.
Thanks!
@ Andy / Mark,
Please guide me.
Is there no one in this forum who has faced issue like me?
I bought Lenovo Ideapad Z410 (model no. 20292) in June 2014. Last year whenever the laptop was started, a pop-up window would appear saying "Battery is too weak" with a BUY icon.
Since April 2015 onwards, my laptop is not getting started, its dead.
How can I download battery firmware update without laptop getting started? Please refer the pictures below, once laptop starts it asks for outlook login and after entering the login credentials, laptop just hangs showing nothing (it hangs for hours).
Lenova Start
Lenova After login
I am facing this problem since April 2015 and till date Lenova didn't responded.
Is anyone facing this kind of problem, if yes how did you got this problem solved? Please guide.
Thanks in advance.

Hi,
I am trying to install this update but I get this message:
there are no attached batteries that require a frimware update.
current battery code is : 0005-0051-0100-0008
please help me.
thanks.
Dear Lenovo,
After perusing the recent comments by multiple users on this post from across the world - it appears that the firmware that you had issued last year - has somehow got overwritten / superceded by some more recent/latest updates - sometime in either late 2016 or early 2017.
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.
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 am sure you need to resolve this issue soon so as to restore some confidence that you are not only a big brand but also a responsive brand - who is reading and resolving its forum posts!!!
thanks in advance.
