Just got my MBP through the post. Q1 Whats the deal with the batteries? I would normally just read through the instruction manuals, but I have heard there is a special way to calibrate the battery when you first receive the laptop hence I am anxious to even start up the new MBP yet. ??? Q2 Also for battery longetivity is it better if i don't keep the power in the laptop when im using it and just charge it each time it dies or should i always keep the power adaptor attached when i can?
