iMac Intel 21.5" EMC 2889 Hard Drive Replacement

Introdução

Follow the steps in this guide to upgrade or replace the hard drive in the iMac Intel 21.5" EMC 2889. Note that if you are upgrading your drive, you will need to clone your existing hard drive onto the replacement prior to performing this upgrade to keep your files and operating system.

O que você precisa

  1. iMac Intel 21.5" EMC 2889 Hard Drive Replacement, Display Assembly: 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 are fast and easy with an iMac service wedge, but can be completed without one.

    • 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.

    • 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.

    • Continue along the top of the display.

    • You may want to run the tool back and forth through what you've already cut a few times, to ensure you get as much of the adhesive separated as possible.

    • Finish pushing the opening tool to the bottom of the right side of the display.

    • At this point, you'll want to run the tool back around the entire display, to ensure you cut as much adhesive as possible.

    • 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.

    • Gently twist the plastic card sideways to create a gap between the display and frame.

    • Move slowly and be careful not to stress the display glass too much—you only need to make a gap of about 1/4".

    • Slide the card toward the center of the display to cut any of the remaining adhesive along the top right corner of the iMac.

    • Be sure to stop before the iSight camera, or you may damage it.

    • Wedge the plastic card into the top right corner once again, and leave it there to prevent the adhesive from resticking.

    • Gently twist the card upward, slightly increasing the space between the display and frame.

    • As with the other side, twist slowly to allow the adhesive time to separate, and be careful not to over-stress the display glass.

    • 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.

    • 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").

    • Hold the display with one hand while using your other hand to unplug the display power cable.

    • Continuing to support the display with one hand, flip up the metal retaining bracket on the display data cable.

    • Carefully pull the display data cable from its socket on the logic board.

    • Be sure to pull the display data cable connector straight out of its socket, keeping it parallel to the motherboard, to avoid damaging it.

    • Lift the display up to a near-vertical position.

    • At this point there is still a strip of adhesive along the bottom of the display that will hold the display to the frame like a hinge. You can loosen this adhesive by working the display up and down a few times.

    • 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.

    • Lift the display up from the frame and remove it from the iMac.

    • It may be necessary to slowly lift from one side to peel against the remaining adhesive.

    • Be very careful handling the display—it's big, heavy, and made of glass.

    • After the adhesive is cut, it cannot be used to re-seal the display in place. Follow this guide to replace the adhesive strips that secure the display to the rear enclosure.

Well done and thank you for this very precise description to access the hard drive. After that, reconnecting the hard drive or SSD is difficult because the very short SATA connector wires do not allow it to be presented well in the axis of the drive connector and it is impossible to hold it firmly with your fingers. Space is very small.

Thank you SO MUCH for this guide. I bought my iMac used from someone who was upgrading to a newer SSD model, and once I got it home and reset, I was understood all too well why he upgraded. So I ordered the kit here and followed these directions. With my iPad propped up next to the iMac on my table, I was able to follow it right through. As others have commented, the drive cable is very short, but I held back the rubber bumpers until I got it connected, and then everything else went smoothly. Now my iMac is like a new machine (minus the newer Thunderbolt ports and other newer amenities). Thanks again!

I was just looking at the dismal trade in options for all my old apple products, and just assumed Id be buying a new computer every 2-3 yrs at retail whenever apple decided mine was out of date, but after stumbling on this site i love the mission, and am actually excited to try some of these articles on my old products and maybe learn a few things. Thank you for all this work its awesome and appreciated.

Can someone explicitly answer if the Temperature Sensor is need for this model? The internet says yes, but the space inside says no.

Thurston - Responder

I’ve the same question Thurston made. I’m planning to upgrade to a SSD but I’m worried about thermal sensor and the kernel_task issue some that some people mention. Is there a solution? This should be a concern?
