Internet or not, a letter keeps repeating itself when i try to do a search. It won't stop no matter what key I depress. Once that letter starts it keeps repeating itself. I have a new can of compressed air and carefully blew out from under the keyboard. Its and Acer laptop. 5 years old. Just started, after I had a website sitting idle for a half hour.

I assume you shut down to blow out the keyboard? Still the same after a restart? What letter is it? So, how do you get it to stop? Reboot?
