I'm working on a Toshiba Satellite L305D-S5881. It's running Vista Home Premium. It was brought to me because the keyboard doesn't work. Then, things got weird. Here's a quick rundown of the symptops I've uncovered so far...

The keyboard does not work in normal mode.
The keyboard does not work in safe mode.
The keyboard DOES work outside windows (BIOS, F8 menu, etc).
USB keyboards ALSO do not work.
Other USB devices work fine.
Everything else seems to work fine.

And some of the steps I've already taken...

Uninstalled the keyboard from Device Manager and rebooted. The keyboard picked back up next boot. No effect.
Ran system restore from a few days go. No effect.
Ran sfc /scannow. Passed OK, no effect.
Ran chkdsk /f /r, Passed OK, no effect.
Disabled all startup items and services. No effect.

Currently I'm running a system restore back to about a month ago. I'm not really sure where to go from here. This is seriously the first computer I've worked on in the past few years to completely stump me.
