I've included the reply that explained the problem best.  A few other responses
confirmed this message.  I sure hope Apple devises a repair program soon.
Apparently, this problem was discussed in this group before.  Thanks to all
who replied.

Lloyd,

The following text is from TidBITs (a Hypercard stack with articles on
the computer industry) which seems to describe your problem:


The second problem is a bit stranger. Robin Goldstone reports that some IIcx and
IIci machines will sometimes fail to turn on with either of the switches. The
probability of experiencing startup problems is higher if the system has been
turned off overnight, strangely enough. The simple fix is to unplug the power
cord from the Mac for more than 10 seconds and then plug it back in. Apple says
that if the Mac doesn't start up properly after the unplugging trick, the power
supply should be replaced. If you are having these problems and you have a power
supply in one of the following ranges, you should give your friendly local Apple
dealer a call and sound pitiful. According to the posting, the serial number
ranges are RGE924xxxxxxx through GE953xxxxxxx AND/OR GE001xxxxxxx through
GE023xxxxxxxS [sic]. Of course, there may be others as well.

Apple has fixed the problem ("Oh, yeah, we should've put a resistor across
capacitor C9 and jumper wire on the control board. Details, details.") and all
the good power supplies now have a white dot adjacent to the Molex output
connector, should you happen to know what a Molex output connector looks like. I
wouldn't if it hit me in the nose. Apple is working on a Customer Satisfaction
Program, so if you have this problem but don't have one of the above serial
numbers please call your dealer and ask for satisfaction. This is the sort of
thing that Apple should replace because it is mind-numbingly frustrating and an
opportunity to win some customer loyalty with good service. 


I hope this helps.

							Bryan
