Power switch not working.

[spindi598]

I finished my build a while ago and found out that my power switches where not working.

The logo on my motherboard lights up as soon as I turn on the power supply, but the power switch just doesn't work.

At first I plugged my F_PANEL pin bundle thing into the wrong slot (no pins were bent, the pins on the board were in the exact same place). Second try, I moved the cable and put it into the right place, but it still didn't work.

I even tried short-circuiting the PWRBTN & Ground pins, but it still didn't work.

Have I broken something?

Tried some more things:

 

• Took motherboard out of case and tested it again.
• Took each ram sticks out and tried them out individually.
• Took CPU out ( there were no bent pins on the back ) and re-socketed it.
• Took out battery on motherboard. Waited probably about 40 mins and then put the battery back in.

After every test I tried shorting the pins again to see if it would boot.

 

The logo on the board lights up as soon as the board is given power. I also tried charging my phone through the usb port and that worked ( These two happened just by giving the board power, NOT after shorting the power pins ).

 

I never saw the error LED on the board light up to any colour.

Sounds to me you're either hitting the wrong pins or you fried something on that header.

Also, it could be that your ancient low quality Zalman PSU isn't up to snuff. Try a modern

decent quality PSU as well.

I'll look into getting a new power supply, I don't currently have a newer one that I can use instead.

 

I checked the motherboards manual to find out which pins are associated with the power switch. I am shorting the power switch and ground pins.
