Power Mac G5 (Late 2005) Repair Extension Program for Power Supply Issues 
Power Mac G5 (Late 2005) 
Repair Extension Program
The Power Mac G5 (Late 2005) Repair Extension Program (REP) for Power Supply Issues covers 
repairs for Power Mac G5 (Late 2005) computers exhibiting power-related issues due to specific 
component failure within the computer’s power supply. If a Power Mac G5 (Late 2005) computer 
fails to start up after the power button has been pressed and the computer’s serial number is 
within the ranges noted below, the computer may be eligible for repair, free of charge to the 
customer. There are no known safety issues caused by this component failure.
Program Overview
The Power Mac G5 (Late 2005) REP for Power Supply Issues covers Power Mac G5 (Late 2005) 
models with a 1 KW AcBel power supply that exhibit one of the following power symptoms:
Computer will not start up after the power button is pressed
No LED activity
The computers must also fall within the eligible number ranges noted below. If these conditions 
are met, the power supply should be replaced under this program.
The REP covers affected Power Mac G5 (Late 2005) computers for up to two years from the 
original date of purchase, even if a computer is out of warranty. This worldwide Apple program 
does not extend the standard warranty coverage of a computer. Apple will continue to evaluate 
the repair data and will provide further repair extensions as needed.
Note: Customers are responsible for the repair cost of any damage caused by accident or misuse, 
or for issues that do not relate directly to the specific power supply issues covered by this REP.
Eligible Products
The program is available for Power Mac G5 (Late 2005) computers that were sold between 
approximately October 2005 and August 2006 and have a 1 KW AcBel power supply. 
Eligible computers must meet the following conditions:
The computer exhibits one of the symptoms described in “Program Overview.”
The computer’s serial number falls within a specific range.
The power supply label lists AcBel as the manufacturer.

Power Mac G5 (Late 2005) Repair Extension Program for Power Supply Issues 
Serial Number Identification
To identify an eligible Power Mac G5 (Late 2005) computer, first check the computer’s serial 
number. Eligible computers have serial numbers with the first five digits falling within one of the 
ranges noted below:
CK539xxxxxx – CK608xxxxxx
G8539xxxxxx – G8608xxxxxx
YM539xxxxxx – YM608xxxxxx
RM539xxxxxx – RM608xxxxxx
All Power Mac G5 (Late 20005) computer serial numbers are located directly below the air 
deflector inside the side access panel.
Power Supply Identification
If the computer’s serial number falls within the eligible range, you must then inspect the power 
supply itself to determine if it is an AcBel power supply. After removing the power supply from 
the enclosure, check the label on the bottom of the power supply. 
Important: Before removing a power supply, inform the customer that a more thorough 
inspection will be required to determine if the computer qualifies for the REP. If the computer 
does not qualify, contact the customer for resolution.

The AcBel label looks like this. Make sure the label lists both “AcBel” and “1000W.”
Excluded Repairs
Customers are responsible for the repair cost of any damage caused by accident or misuse. For 
example, computers that show signs of having been dropped or of liquid spills into the case are 
not eligible for the Power Mac G5 (Late 2005) REP.
Customers are also responsible for issues that do not relate directly to the specific power supply 
issues covered by this program. For example, if a Power Mac G5 (Late 2005) computer is taken 
to an Apple service provider with a power supply failure eligible under the program and a hard 
drive issue, Apple will cover the power supply repair, but the cost of repairing the hard drive is 
the customer’s responsibility.
