    Whenever I go this “deep” into any computer that has a motherboard battery, like the CR2032 for this iMac, I’ll add a new battery to my workflow. I’m in the “neighborhood” anyway.

    The battery is in a spring-loaded compartment, which requires patience and persistence.

    I make sure to test the new battery before installation. (The “3-2-1 Rule” applies: 3 of something means 2, 2 means 1, and 1 means none - I keep spare batteries on hand.)

    When I took part in my dual-drive adventure, I also added a thorough dusting (outside/outdoors) - phew!

    It is far harder than I thought you have to pull REALLY hard and then there will be a little click and than you can gently pull out the RAM.

    Alison Newton - Antwort

    Press really hard, to the point you think you’ll cut your thumb, you’ll hear a slight ‘click’. If it’s not properly installed, the iMac will ‘beep, beep, beep’ In protest upon booting…

    I found it best to make use of the factory ‘pull tabs’. Much much easier than trying to pull the ram out by hand. It may seem like a good idea but, don’t be tempted to use pliers.

    Brian -

    Just FYI you can install 32GB’s of RAM in this machine. I have been using it this way for over 2 years now.

    I was able to remove one side of the ram, but the other side would not budge. I was afraid that I was going to rip the plastic tab out of the computer. Any suggestions?

    Paula McCaulla - Antwort

    Do you know if 3 ram modules installed would work ? or if it should only be 1, 2 or 4 ?

    I currently have 2x2gb installed, but I only want to add 1x4gb to have 8gb in total.

    Thanks!

    Nikokow - Antwort

    Only install 1, 2, or 4. And preferably with the same gb for each module.

    Snuf Box -

    is it completely manditory to take out the ram? why not just keep it in? for some guides for replacing other components you dont have to, but in some you do. why is this the case? does it have to do with not getting shocked because there is power stored in there or some other reason? i was just wondering tho...

    • Beim Installieren eines neues RAM-Moduls, ist wichtig, auf die richtige Einsetzrichtung zu achten.

    • Achte darauf, dass die kleine Kerbe in jedem RAM-Modul (siehe erstes Bild) auf die Erhebung im RAM-Slot (siehe zweites Bild) trifft.

    • Dein iMac hat vier RAM-Slots. Achte darauf, jedes RAM-Modul horizontal in seinen Slot zu schieben. Das verhindert, dass sich die Module zwischen zwei Slots verklemmen.

    • Nachdem du die neuen RAM-Module in die richtige Richtung ausgerichtet hast, schiebe sie vorsichtig ganz in den iMac und benutze deine Daumen, um sie sicher in ihren Platz zu fixieren.

    When reinstalling RAM in this machine or any iMac with upgradable RAM slots push hard to get them to go in (Apple really did make this one harder than it needed to be). If you don't push hard it won't go in and your computer won't work. (trust me on this learned the hard way)

    I am having trouble with bottom 2 slots. As I get beeping sounds when using them. When removed it boots properly. I tried & tried to push the 2 , 2GB ram modules into the bottom slots BUT all get is beeping. Guess I have to settle for 4GB Rather than 8 unless someone has a suggestion.

    The Memory Maxxer RAM upgrade kit for the iMac 12,1 EMC 2428 suggests the machine can run 32 gb but Apple’s website says it can run a maximum of 16 gb.

    Are we sure 32 gb can run on this machine?

    Paul

    steedz - Antwort

    Added 16GB for a total of 20GB, runs great, do make sure of the “click”, the beep is disturbing

    Butt Muffins - Antwort

    2x2 GB 1333 MHz RAM were installed as delivered. I couldn’t manage to get those two out of their slots. I don’t want to damage anything. So, I put 2x8 GB RAM 1333 MHz RAM bars in the other two empty spare slots to have 20 GB RAM in total. The iMac runs fine with it. As described above, make sure to push RAM until they ‘click’ in completely.

    Another comment on DATA & LCD Temp. Sensor cables: I had to remove the vertical sync, and the backlight cable, however, if you have an assistant or/can carefully rotate the screen clockwise/and then have it held up about 5" to 6" at a slight angle, you do not need to remove LCD data cable or LCD thermal cable, however - IMPORTANT: you must have a second pair of hands/or way to securely prop up the LCD. Also, don't rotate too much, since then you will pull out LCD data cable, and it renders the whole exercise moot, or can damage the cable or connector.

    You don't need suction cups. The screen, held by magnets, can simply be pried off using a very thin blade such as a screw driver and fingers.

    Deepsurvival - Antwort

    That's a bad idea. using a metal tool to pry off glass is likely to end with an expensive broken front glass.

    Suction cups are common. Find a couple and do it the safe way. I use some cheap ones that came with iPhone repair kit.

    max damage -

    No need for suction cups, I just stuck my nails (short like guys usually have) between the top part of the screen and body, and it came off easily. I've never done it before, so it seems to be very easy.

    Just completed the replacement of the optical drive with an SSD using an OWC Data Doubler kit. Attempted to remove the optical drive without disconnecting any cables but found it a bit fiddly to orient the screen for good access. I bit the bullet and disconnected them and found the process less daunting than I imagined. Reconnecting them was similarly straightforward if you're careful.

    Tip: you can skip the step for removing the optical drive thermal sensor connector from the motherboard. Still need to remove the sensor from the optical drive but you can leave that hanging and reattach it to the SSD later.

    osienna - Antwort

    I use Garmin GPS suction cup. Work very well

    jc3Dcx - Antwort

    I’ve just successfully installed a 1TB SSD in place of my optical drive thanks to the information here- thank you to everyone who has contributed!

    3 comments- the procedure described here seems to vary between HD replacement and dual HD/optical drive replacement. This can be confusing at times.

    Expect there to be minor differences between the layout described and what you find when you open up your iMac. There are also, surprisingly, differences between the HD enclosure description, and the article provided by ifixit.

    I was able to replace the DVD/HD enclosure single-handedly without fully removing the LCD, or deconnecting any of the cables (steps 5-11). It’s a bit cramped, and fiddly, but I was not happy removing any of the cables despite watching videos, etc., since they all seemed to involve applying more force than I was comfortable with. A more detailed description of how to release them might have helped, but even here, there may be minor variations even within the 2389 model.

    Good luck!

    ivan birks - Antwort

    I did it several times with one suction cup at the end of a kitchen brush. Once with the blade of a swiss army knive, also ok. And i’m pretty sure it works with fingernails too

    Tai - Antwort

    Fingernails are all you need to free the glass from its magnetic hold. If you don’t have them, slip something thin and plastic, like a spudger, at a top corner.

    I can’t get my glass to budge. I’m replacing a cracked one and now it’s about to shatter.

    jamboxmitchell - Antwort

    I know that I'm replying really late but I advise to use clear tape over any cracks so the cracks don't get bigger

    Jace Holmes -

    Check for chips in the glass BEFORE you do this step. If there is a chip when you pull up with the suction cups you will wind up with a jagged mess. If you do have a chip I would advise covering the screen near the chip with clear tape of some kind before lifting out. Mine shattered right at the chip and the resulting glass dust cloud got all over. My solution was buying a new glass screen.

    Wearing Nitrile or regular surgical gloves helps prevent finger prints if you accidentally touch the glass.

    amiller770 - Antwort

    I use a Swiffer duster from above at the last moment before I let the magnets grab the glass cover. This has worked so well the last dozen or so times I’ve replaced a glass cover since I never have access to a “clean room” and don’t wear a “bunny suit”.

    Also, more dust will shed from your skin if you’ve just taken a shower, so I like to finish these repairs in the morning before a shower.

    The metal near the screws is VERY magnetic. Honestly, the hardest and by far most frustrating step was trying to put these screws back in.

    seancourtney - Antwort

    I ran into the same problem - easily the most frustrating part of this process. To help deal with it, I took a drinking straw, cut it to be about 2 inches long, and used it as a chute to guide the screw to the hole. Dropping the screw down the straw, it'd still stick to the side due to the magnets, but using my screwdriver, it was easy to push the screw down to where it needed to go, and the straw kept the screw from being pulled out of place by the magnets.

    josh -

    +1 for the straw tip. Worked a treat!

    osienna - Antwort

    Hmm… yes, the magnets sucks - literally. But if you use a normal screwdriver or a bit, the screwdriver tip or the bit can be “loaded” by the magnets too. Just move the screwdriver (or bit) over one of the magnets and then “plug” the screw onto the screwdriver’s tip (or bit). It will be held by magnetic force. Just enough to move the screw vertically and very slowly into the whole.

    There are some special screwdriver on the market with “claws” to hold screws, but they are hard to find/to buy and expensive. I sometimes use superglue (a LITTLE) to temporary fasten the screw at the screwdrivers tip. This technique can be used with destroyed screw heads too to optimize adhesion.

    • Hebe es nicht zu weit hoch. Mehrere Kabel verbinden das Display noch mit dem Logic Board. Wenn du am Display mit angeschlossenen Kabeln drehst oder ziehst, kann dein iMac beschädigt werden.

    You can use one hand to hold the edge up while reaching with the other hand to disconnect cables. You may want to have a prop handy (like a small book) or an extra person to hold the edge up while you disconnect cables.

    kctipton - Antwort

    Use the teardown guide for your iMac to familiarise yourself with the layout of everything before you dive in. I was able to get an idea of how much clearance there was once the display is unfixed from the frame, where the optical drive was relative to the base etc

    osienna - Antwort

    The harddisk can be removed WITHOUT the next steps. The opening angle of the partially lifted LCD display gives enough room to untighten the two Torx T9 screws of the hard disk bracket, to unplug the two SATA connectors and to carefully lift out the harddisk. There is absolutely no need to dismantle the whole thing.

    All you need is a screwdriver which fits into the room. I’ve used the “Pro Tech Toolkit” from iFixit. The screwdriver with Torx T9 bit fits perfectly.

    The other “tool” you need is either someone who holds the LCD plate or the inner leftover of a kitchenroll, a scrunched paper, a small towel or similar which has to be stuffed between the logic boards and the LCD plate to keep the LCD at its lifted place (careful! don’t unplug any of the cables).

    I’ve opened and changed the harddisks of those 21,5 iMacs a dozen times with the help of the “Pro Tech Toolkit” and a kitchen roll.

    Udo - Antwort

    If i want to replace the HD with a SSD, can i still skip the next steps? I think i can’t because i need to change the termal censor, but i would like an other opinion please.

    Danois -

    “Kitchen Roll” - paper towel core.

    kyoder11 -

    You can absolutely replace the drive without removing any cables. It's a little tight, you need your torx driver to be short enough to fit in the limited space. Be careful not to put any pressure on the cables (the one nearest the front is a good guide of how much space you have to play with). It's helpful to have another set of hands to hold it up while you remove the drive, but I just did it by holding the display up with one hand and it wasn't that hard to remove and replace the drive.

    I wouldn't install any thermal sensor, just use something like Macs Fan Control (free) to adjust the fans so they don't race out of control.

    Hia,

    thx to IFIXIT and 20+ years of computer repair and building experience (all PC) there was no problem at all to remove a 500 Gb HDD from a mid 2011 iMac and replace it with an 500 Gb SSD Drive (with help from Comtec EDV, where i bought the upgrade kit).

    Skip the steps where people are advised to remove the display. Due to my experience it is def better to leave cables and plugs where they are. I lifted the display 12 cm and fixed this position w/ one pencil in each front corner of the case where the other end of the pencil sticked in ascrew hole of the display-frame. Very easy to operate afterwards! No probs w/ the screws of the hdd-frame.

    Some care-taking of static electricity is advised - wear a wrist cable. And don’t forget to press start button after having removed power chord. I had an Android Tablet on the right side, where i could watch these ifixit pages :-)

    thx to IFIXIT!

    w/ regards from cantbtroo from Berlin

    Hans- Peter - Antwort

    Thank you ifixit for the guide. Like so many others I jumped from step 4 to step 10 and left all the cables intact. Felt much safer doing so. Papertowel cores secured the LCD to higher position. There was enough room to remove the old HDD and replace it with a SSD drive.

    Cheers!

    I also was able to proceed with rest of instructions, after skillping steps 4-10, just have to be very gentle, i think it would help to have a second set of hands to hold screen above while other hands are uninstalling and installing hard drive, but i was able to do it on my own

    jacob d - Antwort

    If you have trouble lifting the LCD or accessing the connectors, check if you have removed the right screws. There are a lot of identical Torx screws that are accessible without removing the LCD that have nothing to do with the screen, I learnt that by nearly breaking mine xD

    jinnifer douglass - Antwort

    I agree with everybody that this is the critical step in this fix. Removing it is not that difficult, the description is quite accurate, but I would highlight that the “rotate” part of the step could be detailed: the black plastic tab is attached to the metal lock (golden colored) , which should rotate into the direction of the cable almost 180 degrees to unlock the connector. After doing this you can pull the cable out of the connector, PARALLEL to the board and away from the connector. It travels a very short distance to disconnect. After going through the rest of the steps to remove the display, take some time to examine closely the connector and understand what you have to do to reconnect it on assembly. It helps to fully visualize beforehand, since on reassembly it is difficult to see properly.

    Fernando Walker - Antwort

    Magnifying glasses are needed for this step. Carefully study the cable and how it attaches to the connector. Take a few pictures to help. This is the most difficult step.

    I managed to damage the LCD thermal sensor socket in the logic board. Now the connector won’t stay in place. I know the missing thermal sensor should cause the fans to spin up (they do spin up after a while), but the screen is blank.

    I connected an external monitor and it works fine, so it doesn’t seem to be a graphics or logic board issue. I also replaced the LED driver board with one from a working iMac, to no effect.

    Can the missing thermal sensor be causing this?

    At the end of the job it was even possoible to clean the fan that sucks cool air into the iMac (w/ a paintbrush and a controllable vaccuum cleaner). After that, it’s also a good opportunity to clean the air inlet that is part of the aluminium case (behind the stand - it’s always dusty).

    The thermal sensor connector shown in the red box is the one for the hard drive, not the optical drive. The optical drive sensor attaches to motherboard near bottom left of optical drive fan.

    Reiner Friedel - Antwort

    The guide was correct in my case that this is the Optical Drive sensor. The board has “ODD Temp” written on it. Original HD has it’s own built in temperature sensor without a separate cable to the Motherboard, which is why OWC sells a special “In-line Thermal Sensor” SATA cable with a Temp. sensor that attaches to any new hard drive itself.

    When I was removing the optical drive cable sensor the connector came loose from the board. Is there any way to repair this?

    • Hebe die innere Kante des optischen Laufwerks etwas an und manövriere den Stecker durch den GPU Rahmen am Logic Board.

    • Ziehe das optische Laufwerk vorsichtig aus den Befestigungsstiften auf der rechten Seite des Gehäuses. Du schaffst dadurch Platz, um das Kabel des optischen Laufwerks zu lösen.

    • Lasse das optische Laufwerk hängen und führe den Stecker des Thermosensors vom optischen Laufwerk hinter dem Kühlkörper der GPU heraus.

    On the reassembly, I found threading the optical drive cable back under the GPU frame trying. Here’s some advice: Take some dental floss, form a loop, and feed that loop under the GPU frame. Put the cable into the loop of floss, tighten the loop, and pull the loop back through. This is much easier, faster, and far less frustrating.

    I have already installed the second SSD drive, but due to the size of the drive I need to change it with another SSHD 1 TB drive. Am I right that I have to follow the instructions up to Step 18? Because The SSD is already behind the optical drive, so what I need to do is remove it and install the new SSHD drive and put everything back again. Please confirm.

    This was my only error on reassembly. The SATA cable must be under the black plastic prong. I did not want to pull to logic board again. I managed to bend the black plastic bits and get the cable in the right place.

    Amen. Having been jolted twice from 2 different spots on the power supply, I would recommend covering the power supply with a small microfiber cloth, handling it by the edges and keeping the cloth in place. Cheap insurance. It will also protect the power supply if it touches something conductive on the hard disc when you flip it over to remove the DC-out cable (next step).

    Robert - Antwort

    I did this dismantlte more than 20 times without removing the AC board. The main board still comes out, can be winkled out in the right direction, clearing the bottom of the AC. A lot safer than fiddling around with the AC board IMO.

    • Ziehe das Logic Board leicht von der Rückseite des Gehäuses weg, hebe es dann etwas nach oben, so dass die untere Frontblende des Gehäuses frei wird.

    At this point on reassembly, make sure the optical drive SATA cable is under the black plastic wall prong. The connector must be low to reach the optical drive.

    Terry Creasy - Antwort

    YES to Terry above. The optical drive cable actually pretty much floats loose when the connectors are pulled off. It needs to stay below the transverse wall which is right under the person’s right hand in the photo above.

    Additionally, it would help to take a picture here to remember where the cables all go. You will have some open sockets at the end and it’s a little confusing. There is a good diagram of their locations here: Screenshot #1 at ++https://drive.google.com/drive/folders... Thanks to Timothy in comment for step 41 for this link.

    HI,

    I just replace the dead GPU Card on an Imac 21.5 Mid 2011,

    Got 2x2Gb 1333 sodim in the top of slot.

    When i finish the repair, the mac start normally but except the right memory slot ,When looking at the front of the Imac , (The top and bottom Right Slot memory ) (Dimm Ch B )

    I search on the net and found that i properly knocked the motherboard when I put it back in.

    I think the power Filter, behind the motherboard ,is what cause that.(Because when you fight to put back cable behind the motherboard)

    You need to mention that, next time.

    I’m not sure about that but I think the part C3230. (I do not disasembly it again to verify (It’s so Fragile)

    Can someone confirm that,( And what do i need to do to repair it.??

    Or Do someone have the same problem, (Right slot (Top & Bottom ) Not working.??

Changed the processor in my 2011 iMac 21.5 to the i7 2600 and although the system fires up and works, the system runs at only 46% thermally throttled at 1.6Ghtz. It would appear the higher voltage is detrimental to performance. I had the 2600 in a different machine so didn't cost anything to try, now looking at getting a 2600S as this appears to be the highest speed option for this machine.
