Yoga 720-15IKB (Bestbuy version) battery not working after Bios upgrade

As title says it, I have to keep laptop plugged in. It doesnt run on battery at all. Battery itself aappears to be 100% charged. I ran hardware diagnostics and it didnt show any issues with battery. After some research, I attempted to disconnect CMOS battery but couldnt find it.

 

Any ideas? Is it possible to get older BIOS version from somewhere?

 

Thanks

Hi Jayceesyou! Welcome to our forums. You can try the older BIOS here: https://lnv.gy/2IXBApU. Before proceeding, kindly read the details of the rollback here: https://lnv.gy/2IXBAWW and disable the secure rollback prevention from BIOS. Hope it helps.
