AT Power Supply Help

I have an old motherboard with an AT form factor. (Its a Compaq Presario 5220). I unplugged the power cord that connects the power supply to the motherboard. Does anyone know the general pattern to connect it. (There are three plugs that need to be connected and each are label P1, P2, and P3. Any help would be greatly appreciated.

Leave it to Compaq. every other one

use two connectors. Look as one when they are plugged in. For the two, they plug in such that the black leads are next to each other. No idea about three, so I'm wasting your time except to say email the Compaq [now hp] website and ask. I understand that they can be very helpful.

If it helps, here is a picture of the situation.

I already tried contacting the HP site, the tech support offered no help. They said I should take a prehistoric 6 year-old computer to a Compaq repair center. Anyways... if anyone knows of a good site that has Compaq manuals it would be greatly appreciated. Thanks.

I looked and the connectors are KEYED so you can't get it wrong...

Look at the connection area vs the plug, there should be "silk-screened" on mtrbd. corresponding numbers for P1, P2, P3 in order to help in connection. Yeah, Compaq does things differently, so next time jot down what goes where to reduce confusion factor. Sad

good luck -----Willy Happy

Thanks for your help... I just sort of guessed and it worked. I wouldnt advise anyone doing this with a good computer but if it is over 5 years old it doesnt matter. Only God really matters.
