I turned the PC on today, the fans spun up, but the screen stayed completely black and the keyboard won't light up. I already tried resetting the sw_CMOS and it didn't fix it."

Hard Reset - Diagnostics


On a desktop system, unplug computer.
If the power cord has a transformer (wall wart) unplug from the computer.
Press the power button 2-3 times to discharge residual electricity.



Plug back in then ---

This is how to do a hard reset

  • Turn on the computer by holding the power button down for 20 full seconds then release.
  • Press the Power button one more time (if necessary) to start the computer.
