Could someone help this idiot understand why his keyboard backlighting will turn off and then not allow him to turn it back on? Tried the keyboard settings... told the illumination to NEVER turn off... yet it does... and when I click the F6 key to re-illuminate... I get a denied. WTF? Basically, I want my keyboard backlight ALWAYS on. And, I don't want to be told by my computer that I can't adjust it.
