Ok, I know the macbook comes with 60w power supply and I have read that 85w power supply is backward compatible with both MBP and MB. I have also read in a few places that it may charge the battery faster and the power supply to run cooler if using the 85w one. I have also noted that MB and MBP will run A LOT slower if one takes the battery out and run solely on power supply. Apple has quoted (and I don't really believe this) that the power supply does not have enough "juice" to keep the MB running at optimal performance if no battery is inserted. Since MB comes with 60w and this is not enough "juice", what if I use 85w power supply, and take the battery out? Theroetically, this should increase performace, right? Has anyone tried this and possibly have benchmark results?
