[G4] Mirror Drive on/off Button - Prone to Failure? - SUCCESS!

[jonny]

Success!  Thank you for two approaches.

As it turned out, using the power button on an apple cinema provided 
a way for me to get this puppy up and running.  I went through 
several routines of unplugging, battery out, PMU switch held for 8 
seconds, machine rested for an hour, battery back in, power cord.  So 
it was good to learn and may have helped overall.

I also ordered the CD - "REPAIR & UPGRADE Manuals for Apple PowerMac 
G3 G4 G5" from ebay (about $10.50 delivered), suggested by <I must 
have deleted the email, sorry> which will be a good resource as I 
learn about this machine...and enjoy it.  It's pretty zippy.

Many thanks!

Jonny
