Hello I have bought the chasis of an HP Slim Line S5747C with the factory motherboard and no DVD Rom. I added my own DVD Rom, but as you can see from the picture there is a separate eject button, which has a disconnected cable. Where should I connect that cable to? The motherboard or the DVD Rom? If it's the motherboard, which connector?

"as you can see from the picture" Actually, I can't. I have a hard time imagining the cable situation. –  Oliver Salzburg Mar 23 '12 at 18:59
    
The eject button in the picture is a separate button from the eject button of the DVD Rom. That eject button has a cable that is disconnected. I imagine that cable was originally connected to something that would trigger the DVD Rom to eject. The problem is I don't know what that something is –  Jonas Stawski Mar 23 '12 at 21:16

On further research, it appears that HP replaced the standard lever with a push-button to eject on this model. The connector is proprietary, to the left of the SATA connector on the HP optical drive shipped with the unit.

I've left the previous information here, in case it might aid a pre-5700 model owner.


The eject button on HP Slimline PCs is a mechanical lever that presses the physical eject button on the optical drive.

If there's a cable there, it isn't for the eject button.

The cable, if it leads to that area, is most likely the power/reset/HDD light front-panel harness, but I hesitate to state that without seeing the inside of that specific model.

These end-of-life disassembly instructions may help you identify the cable.

"The eject button on HP Slimline PCs is a mechanical lever that presses the physical eject button on the optical drive." That is not the case on this model. I will post pictures later and edit the post –  Jonas Stawski Mar 23 '12 at 21:23
    
@jstawski Answer modified. It was probably silly of me to think HP wouldn't randomly add a useless proprietary connector to those at some point. –  EKW Mar 23 '12 at 22:21

The end-of life document posted in the answer shows picture of a similar cable in questioned connected to the drive. Thus it seems like the cable should connect to the drive, but the drive i have doesn't have a pin for it. I guess I need to exchange it for another drive with the connector. –  Jonas Stawski Mar 26 '12 at 15:36

If a wire is coming out of the inside of the dvd eject button then it goes into optical dvd drive. The inside of the front appears to have a legacy manual eject but not applicable here. Connector goes in white port to left of sata power connector on dvd drive.
