An old how-to, but still useful- Laptops are different from desktops/towers. They use certain hardware such as PCMCIA cards, infrared ports, batteries, docking stations. Often their hardware is more limited (e.g. disk space, CPU speed), though the performance gap is becoming smaller. In many instances, laptops can become a desktop replacement. Hardware support for Linux (and other operating systems) on laptops is sometimes more limited (e.g. graphic chips, internal modems). Laptops often use specialized hardware, hence finding a driver can be more difficult.
