xps 13 9380 - built in keyboard lag when AC adapter is plugged in.
Has anyone experienced this problem?
I have a dell XPS 13 3980 (June 2019). I've noticed that when the AC adapter is plugged, the laptop keyboard becomes very sluggish. Key presses faster than say half a second are not registering with the computer and it make the laptop unbearable to use. The backspace key presses are even slower to be registered.
Not sure whether the latest update caused this but I hadn't notice this until by today.
