 Many Compaq Presario's use the same lay out for front-panel pin-outs in a series but not all of them, it depends on the motherboard.

Compaq uses either a modified production line MB or their own proprietary MB.

Such as the 5000 series uses the FIC (First Int. Computer corp.) AZ31 with AMD cpu's while the Intel cpu's have a Mitac 6513wu motherboard. Compaq stripped the Bios and most jumpers leaving its upgradeability to only Compaq design.

The FIC originally had the az31 to run at 133mhz memory and 133 FSB (front side bus), Compaq's version the UWAVE runs only at 100mhz. So Compaq's modifications on production line boards is maddening at times.

To help identify your MB this link will show you some motherboard facts and how to ascertain what you have.

Motherboard photo

Most motherboards have writing around the pin-outs to identify each pin-out, look around the pins for text telling you what each pin is, you might get lucky and find the info you need.

The following is a UWAVE motherboards pin outs.

The FIC website has the same pinouts for their az31 as the 5XXX Presario's using the uwave mb plus more info, searching their site turned up helpful info when I needed it.

BMW mother boards front panel

The bmw motherboards are a modified MITAC 6513WU motherboard.

Whether Compaq changed the pin assignments from the original motherboard remains to be seen. I have found that the original board and Compaq's are near identical if not completely identical for pin assignments)

As stated above; connector J10 and its definition of the Button Board (front panel pin assignments).

    Uwave Motherboard

 They match exactly as the UWAVE motherboard and to note the Spider and ASPEN motherboard also. All are 5000 series.

Here is a photo of the actual block connector, you will notice the stamp on the motherboard does have the printing around the block

I have inverted the photo from the original to show you how it matches up exactly.

Here is the finished product with voltages.

 This applies to all UWAVE series and BMW series also the Aspen 1, 2 and 3 series and possibly more.

  * A 3 wire Power LED uses Pins 8, 12 with 14 as the positive. A 2 wire Power LED uses 14 with 12 as the positive.
I don't believe voltages for LED's matter since they aren't grounded to the frame, but the + (positive) leads are probably in the top row. Some systems carry a (-) negative lead for all LEDS and only have 6 or less wires from the frontpanel.

 To help transfer this into what you need can easily be broken down into a new case with an old Compaq MB or a new mb in a Compaq case.
