just have some questions about the bluetooth keyboard... i have a powerbook and i was going to use an external monitor and run the powerbook in clamshell mode.. i just need a keyboard and mouse to complete my setup.. if you turn the power off on the keyboard.. do you have to re-pair it with the laptop.. just wondering incase i put my pb to sleep and turn the keyboard off, i dont want to have to open the lid to re-pair it.
