When I press the o key on macbook pro i get multiple o's When I press the o key on macbook pro i get multiple o's . They also pop up in the middle of writing other words as well.How can i fix this. The o's run across the screen.
Sounds like the key contact is contaminated.

Simple starter options would be...


Switch off the machine.
Repeatedly tap the key, 20 or more times, firmly but not too forcibly.
Turn the machine vertically &amp; repeat.
Use a can of compressed air to blow out any dust/bits from under the keys.


If still no joy, I'd recommend professional repair.
