Question about Computers & Internet
Which pins plug in where
Google your motherboard and download the manual for it, or post the model # for it here. The manual will show the pin out. In general, the pins are usually abbreviated on the motherboard, albeit, very small. The wires will usually be marked HDD, RST, speakers,etc. Sometimes the pin outs are color coded on the mobo, just connect the wires to them color to color.

This solution can only be found two ways. 1. Is to call compaq and get someone in the technical service to help you or direct you to a service center that can provide an answer. 2.The other way is find someone who has a unit just like your's with the same motherboard and ask them to open their unit and take a picture, so you can see the pin set-up.This could happen on this website, if there is someone else that has this model computer and motherboard. You can also put out a help call on the other help websites, hoping someone will help you out. I hope this information helps you with your problem.

Front Panel Header pin assignments as follows:
Pins 2 + 4 = Power Led
Pins 6 + 8 = Power Switch
Pins 12 + 14 = LAN Activity Led
Pins 1 + 3 = HDD Led
Pins 5 + 7 = Reset Switch
Pin 9 = +5v
Pins 11 + 13 = ODD Led
Pin formation is as below with no pin in position 10.
2 4 6 8 10 12 14
1 3 5 7 9 11 13
You will probably need to extend the Front Panel connector cable to reach the header pins on a replacement motherboard - I did this with 2 x N76HL 10 pin extension cables (male to female) from Maplin.
