I got up this morning to find 5 keys not working on my wifes Medion Laptop ( H L N T V )the problem is that one of them is in her password.
The peculiar thing is that at first I thought no problem, I can use the on screen keyboard!
Guess what? the same keys do not work on that either.
Then I plugged in the keyboard from another computer and again the same 5 keys will not respond,
Can anyone give me an idea what is happening here?
