Hi, I am used to cosmetic mods (Xbox 360) and soldering (Xbox 360!) but I am not too good at working out electrical circuit boards for myself without a detailed guide. Basically I need to know where I have to cut and solder wires on the stock Apple Power Board that comes with the Quicksilver and then where I put the other end of the wire on the motherboard (Gigabyte GA-G41M-ES2L). The motherboard: i.frazpc.pl/pliki/2002/auto/1240039934553054.jpg (I won't post it here since it's so big!) Ideally someone would be kind enough to annotate where one end of the wire goes on the power board and then where it goes on the motherboard for each point but any help would be massively appreciated! Thanks, Ollie Attachments:

Just my 2 cents, but how are you wanting to connect the powerboard to your Gigabyte board? Using traditional 2 pin connectors like in this picture and this one? Or are you wanting to use the original cable that still attaches to the powerboard like in this?

Thank you for both responses.
The two pin connectors are easiest I understand so I think I will stick with that - though if using the original cable is as/more easy then that would be the best option.
After reading the topic at InsanelyMac I understand where I cut and solder on the power board but the could you show me where I connect the other ends of the wire?
Many thanks, Ollie

Thanks again Reddrag0n, I have been looking around the Kenji Hackintosh site for a while and have come to grips with what I need to do to the board but I cannot understand where to put the other end of the wire on the motherboard, if you look here ninjatosh.files.wordpress.com/2008/03/switch-4.jpg then you can see that he uses the pins that I have put a ring around in the attached photo but there must be a way to find out which wire goes to which pin - Where can I find the layout of the Gigabyte Power pins? Thanks again! Ollie Attachments:

Well, if that's the motherboard you are going to use, then here is the wiring diagram for the Gigabyte GA-G41M-ES2L Motherboard.

Ah, that is very useful! Thanks, now because I am still learning about electonics etc, does it matter which part of the power switch goes to PW+ or PW-? And likewise for the others. This should all be okay if I only connect the Power, LED and Reset shouldn't it?
When it says Reset, is this a motherboard reset or does it mean restart?
Thanks,
Ollie

here, this will help you out even more... pin 20 = speaker - pin 14 = speaker + pin 8 = power switch - pin 7 = reset switch + pin 6 = power switch + pin 5 = reset switch - pin 4 = power led - pin 3 = harddrive led- pin 2 = power led+ pin 1 = harddrive led +
as for connecting the power led, that would be up to you if you want a constant led on, or if you want it to flash with any hard drive activity.
the reset button is to restart the computer in case of a hangup. it doesn't reset settings in the bios if that's what you were wondering.

Thanks again! PS - Your 700th post!
Maybe you did answer it and I just didn't understand (More than likely!) but does it matter whether I connect the wires to the + or - ?
I won't bother with HDD LED - I'll use that LED for constant LED on.
Thanks,
Ollie

for the power and reset buttons, connecting them either way doesn't matter, but power does have to connect to power and reset to reset. their polarity doesn't matter. the power LED on the other hand does need the proper polarity, or else it won't light up.

Which is the positive and negative terminal for the light on the power board? How can I tell which is which?
Thanks - you are very kind for answering these questions.

Now is where we get into the electronic aspect of this job. Ok, physically look at the light on the power board. you should notice a nub inside the epoxy. It will look like this. On older power boards with the triple post LED, the center is the negative. If you notice that your connector doesn't make the light turn on, simply take the connector to the motherboard and flip it. You won't blow the LED, it will simply not turn on.

Ah, brilliant, so I solder negative to negative? Not negative to positive?
Thanks a lot!

yes, you are supposed to solder negative to negative and positive to positive. like i said, if you are using the little 2 pin plugs, if it doesn't light up the LED, just unplug it and turn it around. then it will light up. the motherboard only has 3.3v to 5v running through the pins. so it won't blow the LED.
but it is a good idea to keep in mind polarity. just makes things simple
