General Information
Overview
Some of the key features that distinguish this computer from the earlier iMac (Flat Panel)
models include:
• This computer uses double-data rate (DDR) memory. Memory from previous iMac
models is not compatible with this computer. Do not use older SDRAM DIMMs or SODIMMs even if they fit into the slot.
• There is an audio line in jack.
• Bluetooth and AirPort Extreme Card are CTO options.
New Procedures
If you are familiar with taking apart iMac (Flat Panel) computers, the procedures haven’t
changed much; however, you will notice some difference with this model:
• The diagnostic test points have moved on the bottom of the logic board. They are now
located near the AirPort card. Refer to the topic, “Diagnostic Test Points” in this
chapter for more information.
• The neck extension is different. The inverter, speaker, and fan cables are part of the
neck extension cables, replacing the blind mate connector.
• There are separate data cables for the optical and hard drive.
• A clutch assembly was added to the door so it closes slower now.
• The Pangea heatsink on the logic board is about two inches longer.
• The diagnostic tool kit (cables), 076-0897, is not required anymore. The cables reach
the logic board when the computer is in the open position; however, you may want to
place something underneath the bottom housing (to prop it up) when the unit is open
to give the cables some slack.
Tools
The following tools are recommended for the take apart procedures.
• The service stand (076-0898)
• Thermal paste (922-4757)
Torque driver (076-0899)
•
• 1.5 mm hex driver (for LCD bezel screws)
• #0 Phillips screwdriver)
• Torx screwdriver set (6, 8, 10, 15)
• Plastic flatblade screwdriver or stylus (922-5065)
• Needlenose pliers
• ESD wriststrap and mat

Page 14
Procedure
1. When opening the bottom housing, rotate the base so the optical drive door is on the
right. (This position is less stressful on the internal cables when the bottom is open).
2. Remove the four torx screws.
Replacement Note:
not have a torque driver, you will have to make sure these screws are tightened by hand
FIRMLY, BUT NOT FORCIBLY. Or, purchase the service tool (076-0899) in order to ensure
the thermal pipe is firmly mated with the top base. If the bottom housing is not securely
attached to the base in this fashion, the CPU may overheat and become damaged. For
more information, refer to “Thermal Paste Application’” in this chapter. Rotate the base so
that the optical drive door is on the right.
These torx screws must be tightened to at least 17 in.-lbs. If you do

and reapply thermal paste to the mating surfaces on the thermal pipe.
2. You must tighten the four torx screws on the bottom housing to a minimum of 17
in.-lbs. Use a torque driver (service tool 076-0899) to ensure that the thermal pipe is
firmly mated with the top base. If you do not have a torque driver, you must make
sure the screws are tightened by hand FIRMLY, BUT NOT FORCIBLY.

unnecessary contact with either side of the thermal pad as dirt and body oils reduce
the thermal pad's conductivity.
