If the CPU is indeed 64bit the laptop company made an awful mistake.
Not necessarily, it could be a 64-bit cpu but the rest of the machine might not support 64-bit. I have a Toshiba laptop like that. It originally came with 32-bit Vista installed. I tried an inplace upgrade to 7, which didn't work. I finally managed to clean install 7 but I couldn't install 64-bit, so it's stuck on 32-bit.
