The computer will not power on. The computer says no signal when it shows up other than the black screen.

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.

 

Let me know what happens.
