The junior college that I attend (Portland Community) does shut down their PCs at night, however, they ALL turn on (in class rooms, labs,offices, etc..) at 7:30 in the morning, regardless of whether or not the PCs will be used in the morning. Furthermore they are not configured to go into sleep mode ever.
Bah.. I think that I'm going to have to write the IT Department an email!
