Hello, Jack E.

Thank you.

Cannot find the Power SW socket on the above layout. Do you know where is it located, please?

Thank you again.

Thank you.

Yes, that is what I did but failed due to the wires are in between the walls. I would have to tear down the walls to find and trace the wires.

Thanks.

Thank you very much, Mr. Jack E.

The walls.

The is a metal case. And the is a plastic cover on top and the front of the metal case. Inside the metal case, there are chambers for the hard drive and DVD drive. There are spaces or gaps between the metal care and the plastic covers. These spaces or gaps are small just enough to let the wires go through.

Color coded wires.

I cannot see color coded wires from the end of the on/off button. There are hidden between the plastic over and the metal case. Yes, I see the color coded wires, about 3 inches long, at the socket or connector end on the mainboard.

Number 11 connector of your layout.

The number 11 connector has 7 pairs of sockets. There is such a connector locate at the same position on the mainboard G45R AM2 V:1.0 in my Aspire Mxxxx, don't remember the model & can't find it, just know the mainboard is G45T AM2 V:1.0 labeled on the board, but it has only 5 pairs of sockets.

Are you sure the layout you posted above is of G45T AM2 V:1.0? It is not unusual that Acer products contain different components for different markets.

Really appreciate your kindness.

"The layout is for the mainboard originally used in the Aspire M5700 desktop which should be the same. " You said.

There are 2 key words: ORIGINALLY & SHOULD. The layout you posted is the original motherboard as advertised and motherboards for M5700 should be the same but they are not as the product sells well on the market and production goes on. This is probably why the real motherboard in my M5700 is different from the original and the should.

These photos show the front & top panels and the signal wires.

Thank you.

The metal case of M5700 is interesting. There is a zinc plated metal case. On top of the zinc plated metal case, there is a baking painted metal sheet, same size & thickness as the zinc case, fastened to the top of the metal case by 4 screws, 2 on front end & 2 back end, and on top of this painted metal sheet, a plastic top panel about 2 cm thick & covers the front half of the top, with 4 USB ports, audio & mic and a compartment. "molded plastic hooks that pop into rectangular holes in the metal frame..." Yes, I thought about this, but could not find any place to wedge or pull it.
