Bypass PSU Switch

post #1 of 7
Thread Starter 
im fixing a HP for a friend, and when i try to switch it on nothing happens. so i tried another outlet and nothing.so i thought i would try a technique that i THINK im doing correctly by taking a piece of wire and connecting the green and black wire on the 20 pin connecter then plugging the outlet wire to the case and still nothing.A...am i doing it the right way,b.c there are more then one black wire?B if A is right does that mean he has a bad PSU?

Black is always ground so it doesn't matter which black you connect to and yes you're doing it right. Sounds like the PSU is dead.

If the motherboard is grounded elsewhere (aside from the PSU), you have a major problem since everything will short out. If this were the case, the PSU could blow completely killing other components as well.

I don't know where you heard that but with a power supply that adheres to the ATX standard (1.x and 2.x), you want to connect the green pin to any of the black (ground wires) to turn it on. raycityclick did it properly.
