I had to exchange the case for an Acer Aspire M1201. The motherboard used in that build is an Acer RS740DVF. The trouble I'm having is that neither could I find a service or user manual for that motherboard, nor are the front panel pins labeled on the board itself. They are color coded though:

enter image description here

What is grey in the schematic is actually colored black on the board.

Is there a safe way to identify which pins are used for what purpose? The case I'm using is a Sharkoon MA-M1000; the front panel wires are Power LED, HDD LED, Power and Reset.

Also, what is the worst that can/is likely to happen if I attach the wires wrongly? Will they simply not work, or is it possible that I damage the hardware?

  • So you don't know what the cables are from the case AND you don't know what the sockets are on the mobo? Right? – Raystafarian Dec 25 '13 at 1:25
  • If you still have the original case, then you should trace the wiring. That's what I did for a Dell mobo. Potential damage due to misconnections would depend on mobo quality. A retail mobo would be built to handle shorts on this header to reduce product returns. Hard to say if an OEM board would save every possible penny. – sawdust Dec 25 '13 at 1:53
  • @Raystafarian The cables from the case are labeled, but the pins on the board aren't. All I have on the board are the colors. – G. Bach Dec 25 '13 at 10:23
  • @sawdust I might try the tracing, wouldn't want to damage anything. – G. Bach Dec 25 '13 at 10:46

Ah. Looks like it's a Foxconn RS740M03A1-8EKRS2H. Google will verify, but here is a source.

Pin layout can be found here. The green/yellow all the way to the right aren't defined. Sorry this is the wrong Foxconn model, but the pin layout is the same, so we're in luck!

This page has the manual, I think. Anyway, the front panel layout is like this:

enter image description here

enter image description here

HDD LED     1 (+), 3
Power LED   2 (+), 4
Reset SW    5 (+), 7
Power SW    6 (+), 8

Switches don't really matter, I don't think, as they are switches. But just in case, positive on 5 and 6.

In general, this is what Foxconn layouts are described as in the manuals -

    That first layout is exactly what I'm looking at, thank you! – G. Bach Dec 25 '13 at 12:46

    I wired everything up according to your first schematic, everything works as it should. – G. Bach Dec 26 '13 at 1:40

While the list above covers most of it, it does not cover the fact that the OP is listing a 14 pin on the board for the front panel of the Acer RS780M03G1-8ekrs2hm.

Acer rs780m03g1-8ekrs2hm

This is the pin assignment:

  • on board pin 1,3 Orange from front panel wires are Red+,White- (HDD Led)
  • on board pin 2,4 Green from front panel wires are Green+,White- (Power Led)
  • on board pin 5,7 Blue from front panel wires not present could be reset
  • on board pin 6,8 Red from front panel wires are Blue+,White- (Power switch)
  • on board pin 9,10 Black from front panel wires are not present(Just to make sure the block is connected properly)
  • on board pin 11,13 Orange from front panel wires not present
  • on board pin 12,14 Green from front panel wires are Green+,Orange- (Lan Led)

The names may not be listed on the block or the main board but if you pull off the front panel and remove the wires\what connects them to the panel, you will find the labels.

The harness part number is M.351003F00A-GY0-G


Providing the pin number (ie, which is pin 1) would be more helpful since most mobo manuals would illustrate pin-outs by numbers. But on most mobos, red would be hard disk led, blue is reset switch, green is power led (not sure which one on your picture above). You could try to momentarily short out any of the adjacent yellow pins to see which one would power on the computer (power switch connector). Also note that there are polarities on the led connectors.

  • I would happily give you pin numbers if I had any :( Unfortunately there is neither a manual nor any sort of labeling on the board itself. I will try hooking up by colors, thank you! – G. Bach Dec 25 '13 at 10:22
  • Pin 1 is usually marked with a white corner. – Raystafarian Dec 25 '13 at 12:40

The pins configuration described above for the Foxconn RS740M03A1-8EKRS2H worked for the front panel of an Acer RS880M05A1 motherboard, although there was an aditional jumper (2 pins) on the right of the front panel pins block, as it is show in the first posted picture of the Foxconn layout.

Thank you!
