A workaround to prevent auto-sleep after scheduled wake System
When the computer wakes up from sleep mode to the authentication screen (i.e. when someone accidentally moves the mouse), it goes back to sleep after 30 seconds if no one authenticates. This is good design. However, if the computer is set to a scheduled wakeup -- for instance, you want the computer to wake up first thing in the morning (long before you get there) to resume background processes -- it will still go to sleep after 30 seconds.

Solution? Well, there's not a great one yet, but a only workaround is to create a dummy account with no rights and set to wake up to a logged-in desktop. Then switch users to this account before sleeping. That way, the scheduled wake will be into this benign account, and your account will still be running in the background. Waking into an open account doesn't cause the machine to go back to sleep.

The obvious solution will have to come from Apple: If it's a scheduled wake to an authentication screen, don't go back to sleep. Maybe in Leopard -- fingers crossed.

A workaround to prevent auto-sleep after scheduled wake

I had the same problem on my home computer, except that I don't usually log out when I put it to sleep. The simple solution: I set a iKey shortcut to press the Escape key when waking (any other key could would work as well).

Better to switch to the login window before sleep, not a "dummy account".

Neither of the above comments get what's going on here. Once a machine goes to sleep, whether the machine is logged on or the desktop is locked, it will wake up to the authentication screen if in security you have "Require password to wake..." set . If no one enters a password, it will go back to sleep in 30 seconds. Having it wake up to an account that does not require authentication, is the only way to avoid it going back to sleep. No?

Actually, "Derivatize" does have it right. When you go to the login window first (from the fast user switching menu) and then click the "sleep" button from there, it will just return to the login window the next time it wakes. It will NOT go back to sleep after 30 seconds. (I suspect it reverts to the usual energy saver settings.)

I use this method every day to connect to a remote Mac that I have set to wake up every morning and sleep every night.
