When I switch the laptop on I can enter the BIOS, move about change settings etc. I can boot into DOS or the Ultimate Boot CD and the keyboard works just fine.
The problem is when Windows XP starts. The keyboard doesn't work at all ! As the desktop appears if I repeatedly press the window key, the start menu pops up but after a certain point, usually when icons start appearing in the taskbar, it just stops working.
My first thought was a driver issue, so I checked the Vaio support website and downloaded the original drivers pack for the model, but it does not contain any drivers for the keyboard. I checked device manager which reports everything as working. I uninstalled the keyboard driver and rebooted and still nothing.
I've opened up the laptop and checked the ribbon cable and the connector and they seem fine.
I've tried re-installing XP, and the DOS based portion of the installation runs fine, but once the Windows based part loads up, I can't enter a user name so cannot complete the setup.
So I am now at a complete loss of what to try next and I am hoping someone with greater knowledge than myself can help me out!
Thanks in advance
