Question about HP FS492AWABA - Compaq dc7900 Convertible Minitower PC Desktop
Remove the power plug from the back of the computer. Take a small screw driver and cross the two vertical leads then cross the left lead to the ground post then do the same with the right one.Plug it back in and see if it turns on then if not it could be your power supply caused by a power surge. Is my guess.
