Can't find wire diagram for a Compaq Presario SR 5000

Hello again,

This is a hardware question on Compaq Presario SR 5000 computer case.

There is one molded header which goes from the Case lights, power reset , HD
etc and the switch setup is in a molded enclosure. In other words I simply can’t see
nor find a manual with the colors that the wires represent. I am rebuilding
a spare machine with a motherboard from my shelf. I have all the documentation on that.

The molded 9 connector square plug has one pin locked and and so I cannot simply plug it in.

What is needed from any source you can find is the info from the case end
which is not so easily searched:

Wire colors from:

Case Power on/off
Power on/off pilot light
Reset
Reset pilot light
HD activity light.

I really only need Power and Reset, but HD would be handy.

Wire colors are 3 black for ground plus yellow, blue and red one each.

There may be a service manual with a diagram of this but I cannot locate it.

One found I will splice some wires to my old replacement mobo.

Redirection to another site is ok, but not the usual ones. They have nothing at TomsHardware for instance.

This is HP’s information page on that motherboard.

Apparently, it’s not an HP-manufactured board. It’s actually an HP badge-engineered EliteGroup ECS 945GTC-M. HP’s version is 945GCT-HM. It differs by having fewer SATA ports and back-panel I/O options, for instance. Probably a reduced cost version for Compaq’s specifications.

The PDF manual for the non-Compaq version of the motherboard is here. (PDF from Taiwan, but I think it’s safe.) Page 24 of the thing has the pinouts of the front panel connector. Just glancing at it, it looks completely dog standard. And I doubt HP would scramble a trivial connector in a badge-engineered/cost-reduction motherboard out of a perverse desire for obscurity and non-standardness. :dubious: So this pinout should do the trick.

N.B.: Don’t confuse that with the (also 9-pin) front-panel audio header. That’s for the microphone and speaker jacks on the front panel, not for the LEDs and switches.

ETA: you’re asking about the case. The case isn’t documented, but the motherboard is, so the connector in the case can be correlated to the motherboard. Q.E.D.

Rather than “wiring diagram”, try searching for schematic or service manual.

This sounds like a better route.

I got the switches going but I’ll have to abandon the project. All the mechanicals work
but the cpu swap-- even though it fits in the AM2 Sempron board will not load the
POST or the Win7.

Thanks for the help. I’ll still look up the schematic if I can for a future build
in this old case.

Just one more ask for the experts. The cpu may be incompatible. But I also used a power supply 24 pin main cable to a 20 pin board with the extra snap in four pin piece
off.

What would that do if anything?
