|I have a similar problem with the same model Gateway. I have an orange power button indicator and, inside the case, there is a green LED on the motherboard. When I connect power and push the power button, there are no other signs of life - my ELP 500c no longer starts at all. I have tried to strip the board down to minimal components. Inside the case, there is a small black button on the power supply clearly labeled "Test Switch". With power connected and the now orange indicator LED on, I pushed the test button. Nothing happened, so I believe this implies that the power supply has failed, which would be the root of my problem. |
Replacing the PS is fairly simple and inexpensive DIY maintenance. This PC is worth the money and effort to attempt this repair, so I am going to replace the power supply with a known good one, to see what happens. I will post my results here, and my steps to replace it, in event the PS is your issue as well.
