T440 Internal Battery issue

I have a T440 laptop that suddenly decided it's having an error with the internal battery that shipped with the system (which is a genuine battery, has not been touched/removed and was working fine until this morning). 

 

The error displaying is:

 

"The battery installed is not supported by this system and will not charge. Please replace the battery with the correct Lenovo battery for this system."

 

I updated to the atest BIOS a few weeks ago, have the latest Power Manager and Power Manager driver as of a few days ago. External/removable battery is fine. Any thoughts on how to resolve this, or anyone else having this issue?

Hi Csubuka,

 

Welcome to Lenovo Community!

 

As per the query we understood that you facing issue with Charging on your ThinkPad T440.

 

Have you checked with performing the battery gauge reset through Lenovo power manger application? To proceed with battery gauge reset, open the Lenovo power manager application click on Battery menu and click on Battery Maintenance option and click on Perform Reset.

 

Hope this helps.

 

Best regards,

Hemanth Kumar

Re: T440 Internal Battery issue

Thanks for the option - I hadn't tried it. Unfortunately, I ran it with no luck. Re-ran it again and still the same result. Hate to, since it's a brand new computer, but looks like it requires a ticket for warranty repair.

Hi Csubuka,

 

Thank you for the reply!

 

I am sorry for the delay in reply, can you please check with resetting the system from the Emergency reset – hole, which will be at the back of the system.
