From the info page:
The affected Power Mac G5 models were sold between approximately October 2005 and August 2006 and feature Dual 2GHz, Dual 2.3GHz or Quad 2.5GHz PowerPC G5 processors.
If Apple or an Apple Authorized Service Provider (AASP) determines that your Power Mac G5 computer is eligible as part of the program, the power supply repair will be covered by Apple for up to two years from the original date of purchase even if your Power Mac G5 is out of warranty. This worldwide Apple program does not extend the standard warranty coverage of the Power Mac G5.
Affected systems will exhibit one of the following power-related symptoms:
- System will not start up after the power button is pressed
- No LED activity
- Note: If your Power Mac G5 is not experiencing any of these symptoms, you do not have to contact Apple or any Apple Authorized Service Provider.
Serial Number Ranges
CK539xxxxxx - CK608xxxxxx
G8539xxxxxx - G8608xxxxxx
YM539xxxxxx - YM608xxxxxx
RM539xxxxxx - RM608xxxxxx
By the way, if you've been bitten by this bug and already paid for out of warranty repairs that would now qualify under this program, Apple or the AASP that did the repair should be contacting you about starting the reimbursement process - but you might want to contact them first to get the ball rolling.
If you're a G5 owner, leave us a comment and let us know if your system is one of the ones affected!
