Hello.
I have a weird problem on my computer.

My current energy saving settings are:
On Low Battery: suspend computer in 2 minutes
On Battery: suspend computer in 5 minutes
On AC Power: don't suspend computer

It all works perfectly except when battery is fully charged. Then, the battery logo disappears from the task bar (i can still find it in the «Status and Notifications» menu though) and the computers uses On Battery settings (so it sleeps after 5 minutes).

Do you know what could cause the problem. I guess it is something with the laptop that disconnect the AC when the battery is quite full not to charge it continuously, but i have no clue on how to solve it.

I am running Debian 11 on a Dell Inspiron 5510 (P106F001) with KDE Plasma 5.20.5.

I hope i post this in the right place.

Thanks you for your time !
