Power button removal and replacement

Hi,

I snagged the power button cables whilst removing the speaker. The cables have pulled completely out of the power button.

Is it possible to remove the power button and solder the cables back on, if so how do I remove it? Otherwise, what are my options?

Thanks is advance.

Ouch! The button housing is glued into the back case. You’ll need to take the HDD, power supply & left speaker so you can gain access to the button from the back side. You’ll need to use a heat gun to soften the glue which holds the housing hopefully you can get to the needed points to splice a new set of wires. FYI - Apple does not sell this part alone.

Dan, many thanks for your advice!

For the benefit of others, I applied heat to the outside computer casing using an electric paint stripping gun. To be honest with you a good quality hair dryer would also have worked. The glue released easily and I was able to remove the switch intact. The wires had broken 1 cm from the switch, which left plenty of wire to re-solder back to the switch terminals.

Thanks again for your help Dan![br]

Thanks for your help ! I also snap the power button cable when I removed the speaker ! I had to apply heat for a good 2 minutes with a heat gun at high setting before being able to remove the button. I guess they put a stronger glue on this model ! The cable snap 2 to 3 cm from the switch so I just weld the wires together back where it broke and put some electric tap for insulation ! Works like a charm now :)

I have this problem too. Literally broke the cable when pulling the speaker out. Is there any where I can get a replacement? I connected the wires back together but I cannot get the adjustment on the hex to get it to act like a button

You'll hate me, Apple does not offer it as a spare you'll need to get the full back case housing.

I did find this one which might work! Power Switch Button 593-0928 for Apple iMac A1225 24" Early 2009 Models

Hi Jeremy, I think that you just have to adjust the middle screw (the one that goes in the brass thread) one you heard the click noise when you push it, that should be good. Worst case scenario, you can still remove the original button, put the cable through the hole and attach an other button. it won't be pretty but at least your mac will be usable

Paul, This is not an off the shelf switch! Take a look at the picture in my answer.

The same thing happened to me today. Broke the wire while removing the left speaker. The button came out quite easily after 1 minute with a hair dryer aimed at the back of the case. It was held in place by strong double sided tape.

Annoyingly, the wire broke just as it comes out of the button housing, so I had to solder in a new piece of wire (very fiddly - but definitely doable, even for a novice like me with sausage fingers).

Put the button back with double sided tape, and everything is working perfectly.

Thanks for all the advice above.

@Steve Mulvey Hi Steve: with my dryer I obtained a very hot surface but the button won't move; which kind of maneuver have you adopted to remove it?

Hey Guys!

I just experienced the same problem and was able to remove the power button using a heat gun. I replaced the button but now I need some new adhesive to put it back together. Any suggestions on what to do?

After cleaning the old glue I just use hot glue again.

I used the original adhesive. This worked for me on the EMC 2889 2015 21.5" iMac. The left speaker housing and bottom of the iMac's chin supported each sides of the button mount pretty well so I'm not sure how far the button would even fall in (if at all) if it came loose. I put 2 plastic guitar picks (common tool for working on phones, Macs and laptops) on the adhesive to protect if from picking up dirt while I soldered the wires back on. It really stayed on very well before I put the speaker back in. I actually couldn't press the button back out when depressing the button, I didn't want to break the button. I figured it's in good.
