[jmk3@crux4.cit.cornell.edu (Jay Krell)]

Someone asked recently about the understressed IIGS power supply
problem. The repair program ended about 1.5 years ago,
but I'll post this message from GEnie anyway for the sake
of completeness:

APPLE IIGS POWER SUPPLY REPAIR EXTENSION PROGRAM
 
 
Cupertino, CA -- January 15, 1991 -- Apple Computer, Inc. today announced a
repair extension program for certain Apple IIGS  computers.  The program is
designed to accommodate the relatively small group of Apple IIGS customers who
have already or may experience premature failure of a certain model of Apple
IIGS power supply.
 
Apple IIGS computers are shipped with a power supply manufactured by either
Dyna Comp, Inc. or Astec.  Both have always met Apple s power supply
specifications.  However,  when Apple decreased its power requirements for the
Apple IIGS logic board,  this new low-load environment caused some Dyna Comp
power supplies to become overstressed, resulting in their premature failure .
Apple has determined that this premature failure was due to the changes Apple
made to the Apple IIGS Logic Board without making necessary revisions to the
Dyna Comp power supply.  As of October 1990, all new Dyna Comp power supplies
were corrected to compensate for the changes to the logic board.
 
After several months of evaluating the situation, Apple has created a repair
extension program that will allow Authorized Apple Service Providers to
replace failed DynaComp power supplies at no cost to the customer until
January 15, 1993.  The new plan also provides reimbursement to customers who
paid for out-of-warranty Dyna Comp Apple IIGS power supply repairs prior to
this program.

DETAILS OF APPLE IIGS REPAIR EXTENSION PROGRAM
 
 
 Q:  Which Apple IIGS power supplies qualify for the repair extension program?
A:  Any Dyna Comp power supply manufactured prior to October 1990.  These can
be identified by a dull, brushed metal case, a serial number beginning with
the letter  I , and the ABSENCE of a red dot on the top cover of the power
supply.
 
Q:  Can this power supply problem damage customer data or peripherals?  A:  As
with any power failure, customers could lose data if they had not recently
saved it to disk.  It will not harm peripherals.
 
Q:  How long will the service program be available? A:  Qualifying power
supplies will be covered by Apple at no charge to the customer until January
15, 1993.  At that time we will review the situation again.
 
Q:  If customers have any concerns or questions, who can they contact? A:
Customers should always first work with their Authorized  Apple Service
Provider.  If they have additional questions,  they can then contact the Apple
Customer Assistance Center directly at 1-800-776-2333.
 
Q:  How do customers obtain reimbursement for out-of-warranty Apple IIGS power
supply repairs incurred before this program was implemented? A:  Customers
must submit the following information by June 30, 1991 to qualify for
reimbursement:
