HP Notebook - 15-ay015ni (ENERGY STAR) suddenly shutsdown on battery even with battery at 60%

[Uavi]

Hello All, first post here so forgive any errors.

My up till now faith full and hard working HP Notebook - 15-ay015ni will now suddenly and with no warning shut down when on battery at around 60% power left and after just under two hours where it used to give me 3+

No battery alert, no warning, no sleep or hibernate, just OFF. Windows log indicates unexpected shutdown.

Any suggestions or anyone had this happen. Possible issue caused by Windows updates?

Many thanks

Thank you for the reply and DM.

By swapping the battery with one from another laptop I discovered that it appears to be the battery that is at fault.

Unless the battery runs firmware that can be updated but I dont think so.
