Then you call it in for repair.
My HP quick touch volume control button is stuck. It automatically increases to max power, and then if you touch the decrease button it automatically decreases to mute (and the + or - sign is blinking all the while). I looked online and this seems like a common problem, but I couldn't find the fix for Windows XP (they only had fixes for Vista and I couldn't figure out how to translate these instructiosn to XP's system). Tech support kept insisting that I reinstall the drivers, which of course didn't work at all...
Does anyone know how to fix this?
