I just sold my 15" unibody macbook pro and did a time machine backup before selling it. Upon receiving my new 13" MBP I did a full restore in leopard. After everything was complete and a restart done I started experienceing problems. First the unit ran very slow, then the sound didn't work at all. My unit registered no sound card attached at all. The battery life was horrible as well. Instead of attempting to return the unit I figured i'd wipe it clean and try to start from scratch. After doing all this the unit started working perfectly again. Battery was great, sound worked, and performance seemed on par with a 2.26Ghz machine. Anyone else experience similar problems?
