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

I was prompted to update my Battery firmware

 

I have a genuine battery in my Thinkpad edge E520 that is out of warrenty

 

The firmware failed and disabled the battery so it is no longer operating

 

How do i reverse this firmware or disable the battery bios check?

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.

 

Regards

i did try your suggestion but battery is no longer recognised. Lenovo have accepted a service request from me and i i have asked for software to either reverse the firmware or a new battery. Lets see if they respond positively.
what they state happened is that the battery i genuine but the firmware failed and damaged the battery
