I own a TiBook 1 GHz (10.3.2) and I've had the same problems since 10.2.5. Last summer I sent it to service (unfortunately I live in Mexico) and they returned it (after 1 month of service!) they reported that everything was okay. I´ve reinstalled, run the same tests and the problems always return. I've never been able to "sleep" the computer and also I have "distortion" problems with the display. I got accustomed to it. Although sometimes I need more than 20 minutes to get it to work.
