Keyboard Giving Transposed Characters
Posted on 2009-02-10
OK, here is one I have never encountered. An associate of mine has a Dell dimension (don't know the exact model) desktop. About six months ago he did a fresh install of Windows XP+SP2. After that he noticed that sometimes pressing a key gave no response. He thought he had a bad keyboard and switched it to another USB keyboard with no improvement. He tried another keyboard, different USB ports, and a PS/2 keyboard, all with the same (negative) result. He then noticed that sometimes instead of "no response" to a keypress, he got a transposed character, i.e. if he presses "c" he would get "*" or "(". The actual key which misbehaves is never the same. He states that the BIOS is NOT the most current available from Dell.
My feeling was that he should flash his BIOS with the most recent version. If that doesn't fix it, could this be a keyboard driver corruption? Could this be a motherboard or power supply (i.e. electrical noise) problem?
