Automatically scheduled to go to sleep

[ancient]

For the past few days, I have been getting a message at about 12:30 that my machine is automatically sheduled to go to sleep in a few minutes. Now, a week or so ago I played around with the "scheduled sleep" setting, but I thought I had deleted the entry (and nothing shows up in the System Preferences|Energy Saver|Schedule pane).

Is there somewhere else I need to look, and how do I remove any lingering entries - it is getting somewhat annoying

You could try turning the option on and back off again.

I've already tried that - several times, to no effect.
