Hello, today when I started my HP ENVY 17 Notebook I got greeted by this HP Battery Alert, Error 601. I tried to look up for solutions online, and I'm currently trying to understand if I should just replace my battery, or this is a battery calibration problem, maybe caused by the update to Windows 20H2 I made.
I'm no tech guru, but I always managed to find a solution to my problems through googling, so if any of the steps I did was actually useless, sorry.
I run a battery report through power shell and this was the result:
My battery capacity was around 25.000 mWh up until yesterday.
I correctly updated my BIOS to the latest version.
I then tried to run the HP System Diagnostics Battery Test on startup (turned on the computer and immediately pressed Esc then F2), but got this result:
I run the battery test on the HP Hardware Diagnostic app, but the test result is "Cancelled". I run Window's troubleshooting tool, I got only a suggestion to change my "turn off timer" from never to something else.
I tried the "unplug, remove battery and hold the power button for 30-60 seconds, then put the battery back on and turn on the pc" trick, to no avail.
If my test results showed a gradual decline of battery capacity I would just replace it, I'm not convinced by this overnight loss of 2/3 of capacity.
"All it took" was to remove the battery, start the laptop while connected to a power source, turn it off, put the battery back on, start the laptop again and now I'm back to 25k mWh capacity, but also a weird 121% capacity 😅 I'll take it, hopefully this helps up somebody else, who knows.
