Laptop "types" letter "Y" continuously as if the key were pressed, even without the keyboard
Posted on 2010-11-08
I have this old compaq laptop that started typing letter "y" once in a while when no key was pressed. The problem became more and more anoying until it won´t let us work with anything. First I thought it was a keyboard problem, but when I disconnected the keyboard and the issue still happened I knew it was something else. So I took out the motherboard and found some strange things, like a little screw out of place, or traces of something that appeared to be a short circuit on the CD-ROM connector. Now I've cleaned as much as I could the motherboard's surface (using a toothbrush and a cleaning solution for electronic circuit boards) and disconnected the CD-ROM too but the "yyyyyyyyyyyyyy.....yyy" is still present (and remember, with no keyboard attached to the laptop). Any ideas of what could be causing this keyboard input?
