System still uses battery when cable plugged

Hi guys, I’m a newcomer around. I don’t know whether it is a problem. When the battery is fulled, system doesn’t switch to ac/dc. On windows it can be possible and it gives more performance. Opensuse 42.2 KDE is my system and I wonder whether there is a solution for this? System still uses the battery when the battery is fulled &100.

AFAIU, it is your hardware that manages the charging etc, but maybe the true state is not reported accurately.

When fully charged, what is reported by the following for example?

upower -i /org/freedesktop/UPower/devices/battery_BAT0

Hi and welcome to the forum :slight_smile:
On my DELL there are three different power options in the BIOS for charging and using AC/DC suggest you look there as well.

It says so.
My computer is Toshiba Satellite P50-B-117. There is no option for battery in BIOS.

This is odd…

energy-empty:        0 Wh
energy-full:         29,428 Wh
energy-full-design:  45,08 Wh
energy-rate:         1,316 W
voltage:             16,341 V
time to empty:       22,4 hours
percentage:          100%
capacity:            65,2795%

I assume the bug is to do with your BIOS.

For reference, I have

power -i /org/freedesktop/UPower/devices/battery_BAT0
  native-path:          BAT0
  vendor:               innotek
  model:                1
  serial:               0

This might be worth a shot…

Oh, Then there is a wrong thing… But how can I fix it? There is no option in BIOS. How can I calibrate the battery?

\What hardware supplier, on HP’s you can press the F2 button and select
battery check and then it should allow you to calibrate.

Hi
Any tools on the Toshiba support site? I would let it discharge on the
battery (turn off any power management, screen savers etc). then
recharge and see if that helps.
