Re: ThinkPad X1C6 not plugged in but icon shows 'plugged in, charging'
I just had the same problem, but found an easy fix. Shut down the laptop. Go to the BIOS, go to Power and find the option to disable the internal battery. Make sure to keep the charger plugged OUT of the laptop, so the bug is happening while you do this. When you do it - the laptop will shutdown and the 'charging' port light will turn off. Then plug in the charger back in, it should be resolved now.
