What is a Laptop PC?

A small portable computer light enough to carry comfortably, with a flat screen and keyboard that fold together. Laptops are battery-operated, often have a thin,backlit or sidelit LCD display screen, and some models can even mate with a docking station to perform as a full-sized desktop system back at the office. Advances in battery technology allow laptop computers to run for many hours between charges, and some models have a set of business applications built into ROM.
