Is it possible for the 5:30 Mac Maintenance task to turn the display on?

I have my G4 iMac (10.4.8) display configured to sleep after fifteen minutes of inactivity. From time to time when I get up in the morning between 5:00 AM to 5:30 AM I notice that the display is turned on, even though most of the time it is still sleeping. Is it possible for the 5:30 Mac Maintenance task to turn the display on?

Thank you.

Yes, if just the display is sleeping, the processor can still run the maintenance tasks.

It could simply bee that your mouse is a laser mouse resting on a surface (or has dust in the lens area) that causes it to shift slightly one way or another intermittently, causing the computer to think you moved the mouse and wake up the display.
