Question about Gateway (4000811) Motherboard
Plugging in the power supply, the mobo LED light inside becomes lit. I hit the power button and the power LED light becomes lit but nothing else kicks in (fans, HDs, bios, etc.). There's a "Test Switch" on the power supply so I pressed it and held it in and the computer boots up normally as long as I keep my finger on the switch. If I were to let go, everything but the power LED light and the mobo LED light goes off. Say I hit the power button for 5 seconds to shut it off. Now when I hit the "Test Switch", the CPU fan and the power supply fan turn on but, of course, the HD and everything else won't because the power button wasn't hit. There are 5 wires coming from the power button area. Three wires are coming from to the dual-color power LED (green/red for standy mode). The other two come from the power button switch. The opposite end of the wires go to the motherboard grouped together. It seems that the power supply is operating fine when I hit the test switch on its side. This must mean that the mobo isn't signaling the power supply to power up when the power button is hit. I can't imagine the power button being bad because the LED does light up when the button is depressed. Does anyone have any ideas what could be wrong?
I'm wondering if you have the jumpers set for the power button correctly on the motherboard. If the test switch is working properly when held in, then there's something wrong with the power button itself (maybe it's not going in enough to turn it on? I've had that problem before and had to McGuyver it with super glue and a little wad of paper to work correctly)
