Hab gerade rausgefunden wieso, TemperatureMonitor mein Book nicht richtig unterstützt:
Temperature Monitor does not fully support the 3 new (Februray 2005) PowerBook series yet. Note that 12", 15" and 17" models use very different architectures and may not be capable of updating their temperature readouts. Support for the February 2005 models will be published as soon as possible, but this will take some time because not all models are actually available yet, and Apple did not release any technical documentation so far.
