I just got my first Mac yesterday, 13" MacBook Pro. I LOVE IT! I've been trying to find out some info on the battery calibration that I can't find anywhere. I have tried Apple's website, Google and MRoogle before I made a new thread about it, so here we go... After the two hour rest and I remove the power adaptor at which point I am running off the battery... If for some reason I need to enter sleep mode, does it interfere with the calibration process, or do I need to leave it on full time?
