I rule out that buttons are depressed. I haven't been able to watch so far.
I have a radio mouse. Don't know if it might be causing any interference? But I can't imagine.
I'm not sure, but it could be that the mouse has spun. But it can be that I'm wrong. Entering letters is definitely crazy sometimes.
I don't press anything and some input comes and then I can't do anything. I think that will stop at some point, but then I usually restart the laptop.
I've already seen something like that in connection with moisture. Maybe you should dry the device in the oven at below 50 degrees.
Take off all the keycaps and clean them underneath.
In any case, there are somehow bad contacts
You could also disconnect the mouse and see if the disorder continues.
Yes, I've tried the mouse before. I'll look for moisture.
Try a hair dryer and warm air. Keep enough distance that it doesn't get too warm. No hot air! Leave the laptop switched off and put the laptop or keyboard upright. The purpose is to blow small particles down and to dry them at the same time.
