I have a hp pavilion a1777c desktop. i had to take it apart to replace hdd and dvd rom and some other parts. i have been trying to get detailed info on where the front power panel wires connect onto the motherboard. HP can't even tell me and i've searched all over the internet. Can you please help?

There is usually a set of pins on the corner that are labeled get a magnify glass and light up the board take the glass and look down on one of the corners it is usually on the right corner of the bottom of the board at the bottom of the desktop case. You will usually see a series of abbreviations. LED, HDD, PWR, RES or RE the pins are marked. Now on the wires to the power button you will see the same wire abbreviations. Just hook up the HDD wire to the HDD pin the PWR to the PWR button wire and so on. RESET wire is RE or RES etc. Those really are the only three you will need. Not sure of the exact abbreviations. But they are lettered enough for you to match them. The best thing to do is try to download the board specs and get a look at the pins one side is neg and the other is positive it would be to your best interest to find the mother board specs for you mother board since you went all over the internet and could not find the board specs. just match the LED and the others they are marked PWR is the main and HDD is just showing when the HDD is working. The reset is for the button to reset the computer. It is basic and not that complicated really. Thanks for using FixYa! John

On the mother board there is a spot uually on the side that has little prongs for attatching the terminals
If you look real close there is tiny abbreviatins for power switch (pwr sw) reset(rst) and so on or front panel (frt pnl) sw 1 or sw 2 ou cant hurt it try it on one or the other you should seee it
