I now have win 8 pro working on my CF31, the only thing I have found not working is the screen brightness hot keys, whick I use a lot out in the garage or outside for my digital shop manuals for my JD tractor or my '59 chevy pickup. I have removed & reloaded the drivers from the Panny win 8 help web page many times but can quite get it. Has anyone else upgraded from the factory installed win 7 pro. to win 8 pro. & got all the hot keys to work? I have done several searches but have not found any help.
