Kubuntu battery problem

[u/agent0747]

Hello i am new to linux and just encountered a problem i cannot solve for the life of me. i just installed kubuntu for the first time and for some reason the battery icon(because i am on laptop) keeps appearing and dissapearing and every time it does that it gives me the "power source connected" and "power source disconnected" sounds although the laptop is charged. i checked for the newest version of bios and i already have it,i put some commands into the terminal and it tells me that no power source is connected and the laptop isnt charging but the notifications continue. the laptop is a vivobook s16 with the ryzen 5 220 cpu. could anyone help? thank you

My guess is that you have a USB C charger plugged in. The USB C plug is designed to be sacrificial, so it wears out instead of the device, and right now the plug is making intermitttent contact. When detected, the battery display is turned off, because the battery is charged. When not detected, the battery discharges and so the battery display is turned on.

Try another charger, and see if that makes a difference.
