No keyboard or mouse on laptop

[Timelord]

My dad was eager to try out OSX86 on his Fujitsu Lifebook P Series laptop, but things haven't exactly gone according to plan. The OS X installer didn't see his keyboard or mouse, so we plugged in a USB keyboard and mouse for the installer with hopes that OS X itself would see them okay. After install, we rebooted into OS X without the USB keyboard and mouse. When we first booted up, the mouse worked fine, until we hit any key on the keyboard. Once that happened, both the keyboard and mouse stopped recognizing input and we were left without input devices. We can get the USB keyboard and the laptop's trackpad working together at the same time, but never the laptop's keyboard without stopping input from the mouse and still leaving us with no keyboard. Is there any way we can get his laptop's internal keyboard and mouse working with Mac OS X? (Reinstalling OS X at this point is not an option we'd like to have to explore as he's spent the day tweaking everything to his liking. Besides, we tried it once already and the same thing happened.)

 

Any suggestions would be appreciated! Thank you!
