iMac Intel 21.5" EMC 2544 Blade SSD Replacement

Introdução

Use this guide to replace Apple's proprietary blade SSD (AHCI/SATA).

This guide is intended for the higher spec iMac Intel 21.5" EMC 2544 models that are equipped with an SSD (Fusion Drive or blade SSD configurations).

O que você precisa

  1. iMac Intel 21.5" EMC 2544 Blade SSD Replacement, Display: passo 1, imagem 1 %32
    Ferramenta utilizada nesse passo:
    iMac Intel 21.5" Cardboard Service Wedge
    $4.99

    • With the hinge free to move, the iMac will be unbalanced and hard to work on. Repairs can be completed as shown, but are faster and easier with an iMac service wedge.

    • If you are using the iFixit cardboard service wedge, follow these assembly directions to put it together.

    • Before beginning any work on your iMac: Unplug the computer and press and hold the power button for ten seconds to discharge the power supply's capacitors.

    • Be very careful not to touch the capacitor leads or any exposed solder joints on the back of the power supply. Only handle the board by the edges.

    • Starting on the left of the display, near the power button, insert the iMac Opening Tool into the gap between the glass panel and the rear enclosure.

    • The hub on the iMac Opening Tool will keep you from pushing the wheel in too far. If using a different tool, insert no more than 3/8" into the display. Otherwise, you risk severing antenna cables and causing serious damage.

    • Be gentle! The glass may crack if pried too much. Use a hairdryer to heat the edges and loosen the tape if the room temperatures are low.

    • Use the tool like a pizza cutter—roll it along through the gap, and it will cut the foam adhesive through the center.

    • Be sure to always push with the handle behind the cutting wheel. If you pull, the wheel might get pulled out of the handle.

    • Run the tool up along the left side of the display.

    • While the opening tool cut most of the adhesive, the display will still be slightly adhered to the case. A plastic card will be necessary to free up the last of this adhesive.

    • Set the iMac face-up on a table.

    • Starting from the top right corner of the iMac, wedge a plastic card between the display and frame.

    • Be careful not to insert the plastic card more than 3/8", or you may damage internal components.

    • With both plastic cards inserted as shown near the corners, gently twist the cards sideways to increase the gap between display and case.

    • If there are any sections that seem to stick and won't separate, stop twisting and use one of the cards to cut the remaining adhesive.

    • Begin to lift the top of the display up from the frame.

    • Only lift the display a few inches—the display data and power cables are still connected to the logic board.

  19. iMac Intel 21.5" EMC 2544 Blade SSD Replacement: passo 19, imagem 1 %32 iMac Intel 21.5" EMC 2544 Blade SSD Replacement: passo 19, imagem 2 %32

    • While holding the display up with one hand, use the other hand to unplug the display power cable. Make sure that you pull the cable out from the plastic tab, and not by pulling on the color wires.

    • Lift the display up enough to have easy access to the connector, but not so much that you stretch the cables and stress their connections (about 8").

    • Be very careful not to touch the capacitor leads or any exposed solder joints on the back of the power supply (boxed in red).

    • Grasp the small tab at the end of one of the bottom edge display adhesive strips and pull the adhesive toward the top of the iMac to remove it.

    • Repeat this step with the other adhesive strip and remove it.

    • If either adhesive strip breaks before it's removed, use a plastic card to slice through the remaining adhesive.

Which kind of SSD can I install? Is this the normal M.2 connector?

Thanks in advanced..

Remember guys: the base model that did not ship with SSD is completely missing the M.2 connection soldered on the board from the factory, and will not be able to mount one. The main HDD can still be swapped for one though.

I have an iMac 21.5 Late 2012 (2.7GHz i5) and I was thrilled to find a vacant Apple SSD slot!

I have since installed an SSD and I am creating a Time Machine backup.

A fusion drive will then be created and the data migrated.

Also really nice to know the RAM can be upgraded to 16GB at some point :)

At first glance I was sure this iMac would not be upgradeable but it just goes to show, you should always physically check!

Early 2.7 GHz models did not have the slot on the motherboard.

Later ones did.

OWC Aura 6G fits...
