Toshiba A100: '78y5' appears when typing in any application
Posted on 2009-07-10
I have a Toshiba A100 laptop. Just recently, it began to add '78y5' and many other different 'words' when I am typing. It happens in Word, IE, notepad,... any application. So far, I tried different things: formatted the hard drive (tried XP and Vista), replaced keyboard at least twice, replaced the hard drive, flashed BIOS,...
It seems to me that it is a problem between hardware components (perhaps audio and some other). Please, help me out if anyone can deal with it. I read all the posts I found online, not one of them is of help and seems to be just guessing.
I would appreciate some expert help here. Thanks you very much.
