[X4U] iMac G4's not waking up

[Spoolman Nancy]

Thanks Simon. Yes, we've done all the normal troubleshooting tips. Even 
did the tip in Mac Addict with the NVRAM. Ran DW, Norton, threw prefs. 
We're changing the battery today on one to see if it helps. The next 
step will be to run and loop the hardware diagnostics, I think. One 
other thing I thought about was to redo the entire system. Otherwise, 
we've tried it all. I'll send feedback if we find out what it is. I'm 
hoping the battery is the issue.
