Safety
Warning: When the iMac 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.
WARNING: HIGH VOLTAGE  Text or photographs marked by this symbol indicate that a potential hazard to your personal 
safety exists from a high voltage source.
The 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 even
•  t 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 iMac 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.

Opening the Computer
Apple authorized, desktop certified technicians only should ever remove the front bezel on the 
iMac. When the front bezel is removed, be sure to always ground yourself and follow ESD-safe 
repair practices
Removing the front bezel requires using a special access card (part 922-7172) to release latches 
located inside the upper corners of the front bezel. Slightly bending the upper quarter  of the 
access tool card will help engage the latch more securely. 
As you are inserting the card to disengage the latch squeeze the top of the bezel, that will help 
take pressure off of the latch and enable it to open easier. Note: If the bezel won’t open, read the 
next topic, Access Tool Modification.
Once the card has been released it is safe to open the bezel. See the Front Bezel Take Apart 
procedure for more information.
