From Wikipedia, the free encyclopedia

A laptop computer, or simply, a laptop is a small mobile personal computer that has components that are similar to their desktop counterparts but are optimized for mobile use and efficient power consumption. Laptops usually have a built-in keyboard and typically employ liquid crystal displays (LCD). There are several categories of laptops like Ultra-Mobile Personal Computers (UMPC), Ultra-portables, Thin-and-Lights and Mainstream.

Laptops are also known as notebook computers or simply notebooks. A laptop generally runs on a single main battery and is capable of doing the same tasks as a desktop computer can. For a given price range, laptops are generally less powerful than a desktop computer as they prioritize their compactness and energy efficiency over absolute performance. Thanks to advances in dual-core processors and perpendicular recording, laptops are giving tough competition to PCs.

A laptop computer, or simply laptop (also notebook computer or notebook), is a small mobile computer, which usually weighs 2-18 pounds (around 1 to 8 kilograms), depending on size, materials, and other factors.

Laptops usually run on a single main battery or from an external AC/DC adapter which can charge the battery while also supplying power to the computer itself. Many computers also have a 3 volt cell to run the clock and other processes in the event of a power failure.
