Product: hp 15-bs020wm

My laptop battery stopped charging so, hoping I could get it or the power circuit logic to "reset", I discharged the battery completely. Even while discharging without the power cord plugged-in, the computer would shutdown occasionally, due to low power. Now the battery state is reported as 2% by  Windows 10 and 0% by Linux (dual boot system) but it still will not charge.

 

The computer seems to be running okay off the power cord. I ran the EFI power diagnostics (ESC at power-on). The AC power adapter passes but the diagnostic does not even detect the presence of the battery (reports "not installed" or something similar).

 

Will a new battery fix this problem?

Okay--this is weird (or a dreaded intermittent fault). After a couple days of refusing to charge and reporting 0 to 3% charge levels (proving to be correct with death being the result when I disconnected the power cable from the "brick"), the the battery suddenly decided to charge to 100% late today! Guess I'll restart and run the EFI diagnostic again.

EFI diagnostic detects the battery and even says the battery passes. It doesn't give me an opportunity to re-calibrate the "gas gauge" so guess it thinks it's calibrated just fine too.
