Title:

Power button loose/no response

Text:

Hi,
-The power button on my 27" 2011 iMac is loose/non-responsive. Since I do not feel any pressure from it (it can actually slide behind the casing a bit and get stuck there), it seems to be broken. I am looking in how to replace it. A lot of info on replacing the power supply, but nothing on the button itself.

-Thanks Dan, this helped a lot. I followed all steps to 32. After that I had to disconnect the drive and was able to remove the logic board (carefully). The remove the fan and the left speaker. Behind that the actual power button is hidden. I use a hairdryer to soften the glue and was able to loosen the button from the casing (see picture)[image|1488856]
-The cause of my problem was that the metal ring that is situated between the button and the switch, was shifted (see picture).[image|1488861] This hindered the button from actual reaching the switch. I centered the metal ring, out the button and switch back on the casing and reheated the glue. Firmly pushing it to make sure it stays in plays. Then I reassembled the Mac, and was able to turn it on. All in all a job of 2,5 hours.
