The function keys are unresponsive on a Windows 8 laptop. Yes I'm holding the Fn key.My son's laptop won't start up, the Shift+F8 keys are unresponsive & even though I have a Win 8 installation disc I can't boot up from it. Also can't get into Bios with F12. I've even tried the unplug everything and hold the power key for a minute. I don't know what else to try! Ideas?
