Hi everybody, i'm new to the linux bussines, currently my Thinkpad e550 is running on dual boot (Windows 10 and Ubuntu 20.04.3 LTS) but when using ubuntu, the batery sometimes doesn't charge when the screen is on. It always does the "charger plugged in" sound and says "charging" for a few seconds but then suddenly just stops. When i close the lid it charges without problems but as soon as i open it again it does the normal "conection" sound but stops chargind imediatly again as described before. Also, from time to time, it just works fine and reboot doesnt help by the way... I really need some helpt on this because in all other terms i totaly love ubuntu
Cheers
Lutz
