1. Is there any harm in removing the battery of my 17 inch macbook pro and using only AC power? Of course I understand that with the magsafe I have a higher chance of cutting the power completely, but any other concerns to take into account? 2. I have heard that the processor only runs at 1ghz without the battery. Is this true and where can I find official documentation of this? 3. Does anyone know where I could find a "dummy" battery to place in the gaping hole if I decide not to run the computer with the battery installed?
