It seems like everytime I play any sort of graphically intense game on my MBP, it seems like I loose my battery power. I reboot into OS/X and I constantly have to recharge my battery. Is this normal: is the XP drawing more power then the A/C adapter can supply when I play some games? I haven't pulled out the battery when I play them yet, sort of because if I am drawing more power then I can supply with my power adapter, I want to make sure I'm giving it. But mostly because I'm bad about knocking out that magnetic power chord!
