In the past month, my usually trusty G5 has taken up a bad habit of refusing to sleep properly. About one time in twenty, it will shut down the displays but not (as far as I can tell) anything else (fans still spinning, pulsating light won't come on). And it will refuse to wake up: I'll be forced to shut it down by holding the power button.
I can't reproduce this reliably, so it's a little difficult to troubleshoot, naturally. Any hints of things I should look at or try doing?
Current peripherals are: Cinema display; Dell monitor; Logitech RF wireless keyboard / mouse; FW400 hard drive; USB2 hard drive; Logitech 2.1 speaker system; sometimes iPod mini.
(I don't think it's the iPod. It used to sometimes wake itself back up immediately after sleeping with the iPod plugged in, but this new problem has happened both with and without the iPod attached.)
