Wiring diagram

SIJohn · ‎02-02-2016

does anyone have a wiring diagram for a Pavilion M9000t? I have two loose wires and don' know where they go on the motherboard. One is a thick white wire that comes from the personal media drive and came loose when I removed the cage to change hard drives. The other is a thin black wire

that comes out of the power supplyI (I think it may be a ground). The computer runs for only 4 seconds and then shuts off.

Please help!

Can you post good closeup pictures of the connectors at the end of those wires?

@Mumbodog,

The hard drive cage and PMD bay are 1 part. The rear of the PMD has a twist-out modular plug. On the way out, the hard drive power and data leads are accessed. There is a video that show this assembly. No where are the other wirings. This does not answer the problem.

I think the white wire connector (PMD) connects to the white , five pin labled "Front USB" on the MOBO.

The Black wire does not come from th PSU, but from the front of the case, maybe from the card reader.

The white wire connector looks like a usb card reader cable.

Hi,

I reconected the thin Black wire to a board on the back of the computer, it ran from the switch on the front. Now, the computer stays on!

Do you think that the White wire connects to the MOBO? I don't have a PMD so maybe I don't need it. I'm going to put the computer back together and see if it boots.

Thanks for all you help!

Nope. Still no boot!:( Guess I need that White wire connected after all!
