PC boot without using standard pins
« on: July 13, 2007, 10:42:33 AM »

Is this possible?

The pins connecting the power switch to the motherboard are faulty on my PC. I felt that there must be an alternative method to starting the machine.
So far I've been looking at booting the PC by using the green wire (pin 16 - PS-ON) on the PSU P1 block attached to the motherboard.
I can hear the motors/fans begin to start but the PC doesn't boot.

I've read that such a procedure was possible on the older style PSU which didn't have the POK grey wire (pin 8 ) and am wondering if it is failing these tests.
Does anyone know what the problem is and how I can get around it?

Any help would be much appreciated!!

Requirements for a PC to boot are generally (though not always):
-CPU
-RAM
-Video card

Are all 3 seated properly in the motherboard?

Are you sure the PSU is good?

Have you checked to make sure no metal is touching the motherboard causing a short?

I really doubt the problem is the pins on the motherboard, as I have never heard of such a thing before...

It's still possible - a trace could have cracked or something.  I remember the term "paper clip trick" being used to describe the shorting of two pins on the PSU connector to start the computer.  GL

About 3 years ago I had a very similiar problem.  I knew everything worked, but when I swapped out cases, sudenly it would no longer turn on.  I tried everything to get it to turn on to no avail.  Then I remembered the "short the green wire to ground" trick, and gave it a go.  To make a long story short, there was no more magic smoke left in any of my electronics.  The moral here...find out the EXACT reason it won't turn on, and fix or replace the faulty part(s).
