i just acquired a new mbp (2,33ghz, 160gb, glossy) i am wondering about two things: Is it normal that i hear the hard drive making minor noise (like little "working" scratches)? It makes these noises even if i am doing no operation at all. A technician at the mac store told me it is because it is such a big hard drive but i never heard of something like that and i have quite some experience with computers... Battery. the first thing i did when i got the computer is to callibrate the battery. When i am plugging the power cable out for five minutes, it takes 45 minutes to get back to 100%. And anyway it takes a huge amount of time to get back to full. Often it stays at 99% for 15 minutes (without that the little LED becomes green). I am used to other standards. Again... is this normal? Third thing: a friend of mine came to my place yesterday. He packed his powerbook out and it struck me how small the transformator of his powercable is. Why did they get back to such huge blocks with the mbp? I am looking forward to read you guys's answers.
