Letter z on Keyboard Keeps appling its self.

Ok here it goes i have a Acer Aspire One #532 net-book. I have run into this that i have the letter z types its self on anything that it can add type too. Its been reformatted and still the same issue.

 

Odd. Could be something is wrong with the Z key on your keyboard. The Z key might be mechanically sticking (like staying pressed as if pushed) or electronically (due to some contaminate spilled into the keyboard). Have you done some trouble-shooting on the physical key itself?

 

If you can disassemble your keyboard, take out the rubber mat inside and gently wash it with water and maybe a SMALL amount of dish soap, dry THOROUGHLY and replace it, put everything back together and try it again. I spilled a drink in a keyboard and it was constantly printing "s" afterwards . Had to buy a new one, it was an ancient keyboard and the rubber mat was falling apart. Keyboards arent terribly expensive .
