iMac Intel 21.5" EMC 2544 Camera and Microphone Cable Replacement

Don't forget to place the mac face up on the table. Unlike older models, there is no more flap at the bottom holding the display in place. If you do these steps with the Mac upright, the screen will pop out, hit your table, and shatter :( Don't ask me how I know.

So sorry. Thanks for that caution.

John. May I contact outside of this posting for a question please? Thank you. Ted.

After removing the display, I also removed the 3 screws for the processor fan, disconnected the power connector for it and set the fan shroud aside. Disconnecting the remaining cable (similar style to 1 of the cables for the display) that is in the way of the RAM chips is all that's left to do. I was then able to access and quickly remove the two Apple-provided RAM chips, and replace them with 3rd party RAM. Turning the iMac on its side, so that it's in a position where you're physically putting the RAM chips DOWNWARD into their respective slots is the best way to go about uninstalling and reinstalling the chips. Using a narrow but long'ish plastic spudger tool is the best way to defeat the spring-tabs which hold the RAM chips in place. After removing the LCD display, changing the RAM is about a 10 minute process!! And I'd SURE prefer not to remove all the parts and risk damage to the iMac via the standard procedure listed. As per usual, take your time and work gently :-)

Teardown the whole machine just to change RAM? While preparing to comment on this procedure I just noticed the comment made by Mitch K above. I ran pretty much the same procedure that he describes this afternoon (steps 1-23, 43-45, and step 55). Then I swapped out the original 2x4GB RAM chips for 2x8GB chips by reaching behind the logic board, releasing the spring retaining clips one chip at a time (starting with the chip further away from the logic board), pivoting the RAM towards the back of the machine, and then carefully sliding it out of the slot. I easily slid in the new chips and then pivoted them to lock them down. No hassle, no time lost. As Mitch K states above, not only is this “shortcut” method much quicker and easier, but it provides less risk of damaging cables, sockets and other delicate components during a total teardown. Why mess with the power supply board just to change RAM? I do not advise to follow the current iFixit.com procedure written by Sam Lionheart, regardless of user skill-level.

THAT sounds one !&&* of a lot easier than the full tear down. I wonder if there’s a video of the process described by Mitch K? Adding that to these verbal instructions would really help relieve the apprehension and anxiety around the process! I do sometimes find the additional warnings, though appreciated from a “safety first” perspective, are somewhat overstated. It’s been a very long time since I shorted out RAM, or fried a PCB, or broke a connector, regardless of how finicky, fragile or awkwardly designed and positioned. I may have WANTED to break something, and the air might be blue for a few seconds, but inevitably, things go back together, the start button gets pressed, the startup chime sounds, and we’re in business. Practice DOES make as close to perfect we are likely to get.
