Hello Two days ago I received my new Inspiron 1520 Notebook. Due to the fact that I don't like the pre installed version of Windows Vista Home Premium and the partition layout I reinstalled Windows Vista Home Premium. Now my problem is that regardless which Power Profil in Windows Vista (Maximum Speed, Save energie, or balanced) I choose, the processor speed stays the same. Is there a specific driver I have to install? Is somebody experiencing the same problem? regards Moewe
