How to identify your iMac

On the bottom of your iMac stand, you'll find a label with the serial number printed on it:

Serial Number Macbook Pro 2007

This label also provides the computer configuration and an "EMC" number (EMC No.). The EMC number for the iMac (24-inch) computer is 2111. The EMC number is unique for different iMac models.

To confirm the configuration from the Apple menu, choose About This Mac. The Processor listing will show the speed of the processor followed by the processor type.

The iMac (24-inch) has several features that distinguish it from earlier iMac models:

  • 2.16 GHz or 2.33 GHz Intel Core 2 Duo processor
  • Mobile Express Module (MXM) type II video card: NVIDIA GeForce 7300 GT, 128 MB or NVIDIA GeForce 7600 GT, 256 MB
  • 24-inch TFT 8:5 aspect ratio flat panel display (1920x1200 native resolution)
  • 250 or 500 GB hard disk with serial ATA 150 MB/s interface
  • Up to 3.0 GB system memory

Note About Images in This Manual

Because a pre-production model was used for most of the images shown in this manual, you may notice small differences in appearance between the image pictured and the computer you are servicing. However, the steps and sequence are the same unless noted.

Tools Required

The following tools are required to service the computer:

  • ESD-safe workstation and mat
  • Soft, clean towel or cloth (to protect the display and removed parts from scratches)
  • Access card (Apple part number 922-7172)
  • Black stick (or other nonconductive nylon or plastic flat-blade tool)
  • Phillips #1 screwdriver
  • Phillips #2 screwdriver
  • Torx T6 screwdriver (magnetized)
  • Torx T8 screwdriver (magnetized)
  • Torx T10 screwdriver (magnetized)
  • Flat-blade screwdriver
  • Needlenose pliers
  • Permanent ink felt-tip pen


For most repairs, the unit should be placed screen-side up, with the bottom facing toward you. Most photos in this manual reflect that orientation. The SO-DIMM slot is located beneath the front bezel and is more easily accessed with the unit laying down on a soft, clean cloth.

Serial Number Location

The computer's serial number is located on the bottom of the computer stand.

Serial Number Underneath The Stand Imac


Warning: When the computer is under power, be aware that the power supply contains high voltages that pose a potential hazard to your personal safety. Never work on or near the power supply with the unit powered on; and as a further precaution, always make sure the unit is unplugged when working on it with the front bezel removed.


Text or photographs marked by this symbol indicate that a potential hazard to your personal safety exists from a high voltage source.

The AC/DC power supply board is a high-voltage source with the unit under power, and remains powered up whenever the system is plugged in, whether or not the system is turned on. Use extreme caution when troubleshooting the system with the front bezel removed.

  • Disconnect power to the system before performing maintenance.
  • Don't work alone. In the event of an electrical shock, it is important to have another individual present who can provide assistance.
  • Keep one hand in your pocket when working on any computer that is plugged in. This will help ensure that your body does not provide a path to ground in the event that you accidentally make contact with the line voltage.
  • Don't wear jewelry, watches, necklaces, or other metallic articles that could present a risk if they accidentally make contact with the power supply circuitry.
Zoll Lcd With Small Bezel

Opening the Computer

Only Apple authorized, desktop certified technicians should ever remove the front bezel on the computer. When the front bezel is removed, be sure to always ground yourself and follow ESD-safe repair practices.

EMI Shielding

The rear cover of the computer is wrapped in EMI shielding that is easily torn and damaged. To maintain a properly shielded unit, you must repair all accidental tears and cracks to the shielding by covering them with EMI tape that can be found at your local electronics supplier.
