On my macbook, on the left hand side, where the second screw from the front is, I'm able to push the plastic in. It's almost as if the screw is loose. Anyone else with similar experiences? Secondly, the left hand side at the top (near the magsafe) buzzes whenever it's plugged in, unless I have the isight or my mighty mouse on. Does anyone know what Apple is doing (if anything) to remedy the problem? Thirdly, how long does it usually take for the computer to recognize a bluetooth mighty mouse? Sometimes it's upwards of fifteen seconds for me. Thanks for any and all help.
