Thinkpads are the rare exception. Most of (all of?) the screws are simple Phillips, and the manual provides good instructions on how to disassemble. I've worked on other laptops from other manufacturers; IIRC, I had a Toshiba with Torx screws. No manual, and it also took me forever to find the last two screws as one had a rubber stopper glued over it (that you had to half destroy to get out) and the other had a sticker placed over it.

MBPs have the weird "pentalobe" screws, AIUI.
