This might not be the best forum for this question but I don't
know quite where to look for an solution...
I have a program that uses the IO Power Manager API to queue a
wake request to fire about a minute and 15 seconds before cron is
scheduled
to fire ( at 3:15 in the morning).
Examining the system log I see that the system goes back to sleep
in about 3~4 minutes after the wakeup call. The Energy Saver panel
is set to sleep in 15 minutes of inactivity.
Why is there such a big discrepancy in the time? It appears to me
that a big backup might get timed out by the sleep mechanism...
I suspect there might be some watchdog timer set every time a key is
pressed or the mouse moves, at 3:15 there is no one about to jiggle
the keyboard/mouse.
Is there a software solution to this problem...would an Applescript
system event fake click do the job?
I guess one solution would be to point a photosensor at the screen so
that when the wakeup occurs, the sensor could cut power to a
electromagnet
holding a ball above the key board but that seems like overkill :)
