Does anyone know how to remove the G5/Mac Pro power button? I would prefer not to break it, so a non-destructive way would be top notch! I'm assuming that the metal ring is keeping it in place, but I'm trying to figure out how to remove it without breaking it.

Feel free to take the image below and edit it to point out how!

Indeed, the ring is keeping everything together. You must pull the ring out by making it turn around out of the metal circle. All the parts come out then.

Thanks for the tip - it's sort of a tough job!

That's great news!

I got it off in the end, it's important to point out that you don't have to worry about damaging the PCB since it's not electronic. The only things you have to mind are the solder points, but I ended up using a knife to push the metal ring around, scratching the PCB but causing no damage. Getting it back on was equally as tricky, but I managed in the end!

I'd do that like this:
1. Turn the ring that holds all the parts using a spudger or a screwdriver

2. Using thin-ended pliers, squeeze the ring to remove it

Please excuse my quick and dirty Photoshop :)

Thanks for pointing that, I did not know about the non electronic PCB

but I ended up using a knife to push the metal ring around, scratching the PCB but causing no damage. Getting it back on was equally as tricky, but I managed in the end!


Well done.

@ 3,14r2 Very nice and clever, I didn't thought about that way. I will add your method to the How-to . I pulled the ring all the way around with this tool :sorry for my old bad pix you can see here : (http://www.insanelym...attach_id=39970) , I was not allowed to relink the pix.
Will make a better one for the How-to. Btw, your photoshop is quick but not dirty .

Here some pix, difficult to do inside the case because of the brightness, I took the pix with the removed parts on the table . ;)

Left of the green panel, the light grey spot is the open circle which maintains the panel in place.
Right of the green panel, the bright grey spot is the metal piece under the green panel which maintains the button in place.

Once the panel button out,

you will see the metal keeping the button in place and underneath the button itself

Now you only have to put back the parts in the other case in the reverse order. :D

I use this to extract the parts :
