Server Turns On Every Day At 1:00Pm

I have my backups scheduled to start at 11:00 pm, and the server does turn on then

and does the client backups.  It then hibernates until 1:00pm, turns on until LightsOut

again puts it to sleep.  I have searched all over for the setting that causes it to power

up at 1:00 and cannot find it.  I only want it to start up for the backups at 11:00pm.

Any ideas where to look for the setting that causes it to turn on in the afternoon?

Thanks,

Andrew
