Last month, my iMac G5 at work started rebooting randomly. (If didn’t have my Energy Saver system preferences set to restart automatically after a power failure, I suspect it would probably be shutting down instead of restarting.) Looking through system.log, I came across this:
Aug 29 17:59:26 localhost kernel[0]: AppleSMU -- shutdown cause = -110
Searching Google revealed very little about this error number. As the week went on, the reboots became more frequent. When I finally brought it into the Apple Store, it wouldn’t even turn on for them.
As it turned out, my problem was solved with a power supply replacement. Even though this iMac wasn’t covered under AppleCare, the local Apple Store replaced the power supply free of charge.

Thanks for this! I am just having this error show up in my log after a couple of spontaneous shutdowns. So relieved to know its an easy fix.
This problem is covered under an Apple repair program.

Geoff, my iMac didn’t fall in the range of serial numbers that that Apple extended repair program covers. FWIW
