Edit Step 1 Glass Panel  ¶ 

  • Before beginning, unplug your iMac and lay it on a soft surface as shown.

  • Stick a suction cup near each of the two top corners of the glass panel.

  • To attach the suction cups we sell, first position the suction cup with the movable handle parallel to the face of the glass panel. While lightly holding the suction cup against the glass, raise the movable handle until it is parallel with the other handle.

  • If your suction cups refuse to stick, try cleaning both the glass panel and the suction cup with a mild solvent.

Edit Step 2  ¶ 

  • Gently lift the glass panel perpendicular to the face of the LCD enough to clear the steel mounting pins attached along the underside of the top edge of the glass panel.

  • Pull the glass panel away from the lower edge of the iMac and carefully set it aside.

  • During reinstallation, be sure to meticulously clean the inside of the glass panel and the face of the LCD as any dust or fingerprints trapped inside will be annoyingly visible when the machine is turned on.

Edit Step 3 Display  ¶

  • The last two pictures are detail shots of each side of the display.

Edit Step 6  ¶

Edit Step 7  ¶ 

  • Grab the plastic pull tab secured to the display data cable lock and rotate it towards upwards.

  • Pull the display data cable straight out of its socket on the logic board.

  • Do not lift up on the display data cable, as its socket is very fragile. Pull the cable parallel to the face of the logic board.

Edit Step 9  ¶

Hi guys, the tools arrived today and I did already chage the default harddisk against the WD Velociraptor 500GB. For now everything is working fine. The iMac is in the middle of restoring the time maschine backup. Everything worked out as described. Excellent! I was just a little surprised by the magnetic forces which one needs to overcome gently...

Is there a temp sensor that monitors the HD? I did the upgrade but now my fan is always on. I must've done something wrong.

Did you use the same brand hard drive? Did check the instructions about cable orientation on the hard drive? Did you double check the LCD thermal sensor cable?

Scott Dingle,

Take a glance at this page for full explanations:

I had the same issue here (after replacing the original HDD by a 1TB WB Caviar Blue) and it has been fixed by this utility.

HTH,

Jo Campos,

In response to the software, that does work, however, it can be taken care of hardware wise if our recommendations are followed.

Scott Dingle,

Hi, I'm no stranger to upgrading my Macs (been doing it since 1989). I've followed this guide too since the inside of my '11 iMac is a little less upgrade friendly and my fans spin up afterward as well even if the computer is just sitting there idle. I replaced my factory internal 500GB WD drive with a 2TB WD drive. It doesn't take long before my fans start to spin up. I've checked and rechecked all of the cable attachments. What else could I be doing wrong? What are your referenced recommendations that take care of this with a hardware solution? My best find so far is a donation based version of the above mentioned S.M.A.R.T. tool (http://exirion.net/ssdfanctrl/).

sash5,

Thank you iFixit, another successful repair. Upgraded 1TB hard drive to 2TB, no issues at all.

Im sorry to say, If it sparked when you touched it your motherboard s now fried. You need a new one.

Robert Wacker,

When putting the display down on the table, be careful not to kink the flat ribbon cable.

The replacement hard drive I used doesn't even appear to spin up and the Time Capsule restore process doesn't show it as available. It just stays at Searching for disks and never finds it.

I had to use Disk Utility to partition the drive and then it showed fine. Rookie mistake.

JRBv3,
