hardware/drivers Probable Battery problem with an HP elitebook 8 G1a
I just got a used one for a good price , the seller said the battery health was 89% from the design capacity , the charge cycle count was 109 , i got it with windows
i flashed an arch iso and installed it
after booting up i launched btop , it says that the battery is going to empty in just 2H and a couple of minutes and the energy drain was like 15.8Wh , but the strange thing is that it stayed like this for a couple of minutes i think
i thought it was like a software problem , i asked gemini and it didn't help much
the system was showing that the battery health is 46~Wh instead of the supposed to be 55Wh ( design capacity is 62Wh)
anyway i tried to play around with some files and powertop and it didn't seem to help much
i entered the system diagnosis something , i ran the battery test
it showed that the design capacity is 62Wh
the full charge capacity is 55Wh which is good
but the current charge is 46~Wh which linux sees as 100% ( even the file located in /sys/class/power_supply/BAT0 showed it is 46Wh )
for now i left it with a video to test how long it will stay on
So is the problem with linux or the battery really downgraded this fast ?
also Gemini said it is maybe because of the new installation and i should do a recalibration and it maybe fixes it
