After having exchanged for the 15" 2.66 before being able to open up the 2.53 received last week, now I am having my 2.66 in my room. However, now I am confused on what I need to do first to my new laptop before being able to normal operate it. First question, do I need to charge the battery before I first startup the laptop for certain long period of hours? Second question, if I need to charge the battery for certain long hours before I can start to use it, how do I do the calibration of the battery and also how to do the screen calibration? Third question, after doing all those software updates and some of the applications installation, I am planning to install XP via bootcamp. I heard that all the drivers needed for the XP are included in the OS X DVD, is that true? Or I have to install other drivers in order to let XP operates normally? That's about it before I startup my new laptop. Need helps from you guys. Thank you.
