I have a Gateway elp 500c problem.

November 10, 2010 at 05:23:39
Specs: Windows XP
My computer is booting up and for about 2 minutes and then going into sometype of standby mode. The green power light turns to an orange light. The only way that I can get the power back up and light to green is to disconnect the power supply and plug it back in. Then it will come up to Windows for just a one to two minutes and then the screen will go black and the power light will go back to orange. Do I have a transformer problem inside of my power source area of the computer? If so......what do I need to do? Does Gateway still have parts for this model? The complete model # is Gateway Model-MFATXFTL ELP 500c 10/09/01. Please help if you can.............Thanks

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.

As promised, here is my follow up to my last post about the ELP 500C, for anyone else who may have this model and problem. I replaced the proprietary Gateway PS with a standard 300 watt ATX unit. Since they are approximately the same size, it fits and the two support screws lined up perfectly without any case modifications whatsoever. The connectors are all standard, and can only fit the correct way when you hook them up, so this is pretty elementary PC maintenance. Once in place and connected, my ELP 500C started up and ran like new.

If you have similar symptoms with a unit like this, it cost me about $20 to fix and was well worth the time I spent doing the work.

I was given a Gateway with a similar problem. After replacing the power supply with no results I checked further. Near the CPU there are about five electrolytic capacitors with a brown substance appearing on top of them. After searching "bad capacitors on motherboards" I found this is a common problem. The cost of replacing the items is more expensive than replacing with another motherboard. Found a replacement mobo with CPU for $45 on the net.
