Power switch on case does not turn on or off pc.

[dirty red]

Power switch on case does not turn on or off pc. I've tried the reset switch on this case, the power switch from a different case, and turning the plug around with no luck. I tested all the switches with a voltmeter, all tested the same. So I assume the switches are good. The power button on the mobo works. I can turn it off with the power button on my keyboard (cheap GE keyboard) and on with any key on the keyboard (set in bios). I've tried different settings in bios and still nothing. I cleared cmos also. Everything is updated to my knowledge. Not a huge issue, just wondering what is wrong. Any help would be great.

Thanks in advance.

So it's only 1 problem.

Try shorting the PWRSW pins with the tip of ballpen or a jumper cap held by tweezers. Look it up in the manual.

That didn't work either. Could it be a bad mobo?

Assuming your physically jumping the correct pins and it still does not start up it, theres only 2 real possibilities. Either the power supply is getting the signal and not turning on and the power supply is dead, or the mother board is not sending the signal to the power supply and the motherboard is dead. You can try jumping the pins directly on the power supply to make sure it turns on. You can find the instructions for that online as I dont remember which pins off the top of my head.

EDIT: And now that I read the entire post I see the power supply does work, so it sounds like the mother board is not sending the power signal to the psu from the front panel connectors and the motherboard is bad.

If the power button on the board works, then you are either putting the case power switch on the wrong pair of pins or you have a faulty motherboard. Take a second look at the diagram in the moherboard manual.

I've triple checked the connections, all good. Other than the silly switch it works fine. I've emailed abit 2 weeks ago, no response yet. I'm gonna call them today and see what they say. REALLY don't want to take pc apart. Thanks again guys.

Yes, I suspected the wiring/case.

Is there any way to disable the power button on the GE keyboard? My little one is able to easily turn off the computer now.
