Does anyone know the correct part number for the power button on a Dell 8930?  My switch still works, but the white LED no longer lights up.  Amber LED is still working.   Nothing wrong with the computer except for this issue. My machine is out of warranty and this seems to make it very difficult to get anyone at Dell to respond. Does anyone know the phone number for Dell parts where I can speak to someone who would help me with purchasing a replacement switch or give me a part number?
