My Macbook Pro has a couple of problems which seem to be related. I'm wondering if anyone else has these problems and if they have any advice for me.
1) After a day or so of use, my laptop refuses to sleep or shutdown. I have to do a HARD shutdown by holding down the power button.
2) Again, after a day or so of use, my laptop loses track of my 2 HP network laser printers. The print jobs go to the cue, but don't print. Upon rebooting, they print from the cue. I'm using Bonjour, so I don't understand why this is happening.
