I was wondering what everybody does with their MacBook at night. The first night I had it I shut it down and booted up in the morning no problem. Last night I put it to sleep and I just felt weird leaving it plugged in and on all night. When I opened it from its sleep my dock was gone and I could not retrieve it so I rebooted it and everything was back to normal. Any suggestions as to what is the best mode for my MacBook at night?
