Hello, I just bought a T5010 and have done a clean install of XP Tablet on it with all the drivers from the Fujitsu site. Everything is working fine, except for the F6 and F7 keys to adjust the brightness. F8 and F9 work for the volume though. I know it's not a hardware issue, because the system came with a different hard drive that had XP Tablet on it, and everything was working fine. Any ideas? Other than that, I am loving this tablet!
