A laptop is powered by mains electricity via an AC adapter, and can be used away from an outlet using a rechargeable battery. Laptops are also sometimes called notebook computers or notebooks.

3 History As the personal computer became feasible in the early 1970s, the idea of a portable personal computer followed. A "personal, portable information manipulator" was imagined by Alan Kay at Xerox PARC in 1968, and described in his 1972 paper as the "Dynabook". The IBM SCAMP project, was demonstrated in This prototype was based on the IBM PALM processor. The first laptops using the flip form factor appeared in the early 1980s. The Dulmont Magnum was released in Australia in 1981–82, but was not marketed internationally until 1984–85. The $8,150 ($19,630 today) GRiD Compass 1100, released in 1982, was used at NASA and by the military among others. Displays reached VGA resolution by 1988 (Compaq SLT/286), and colour screens started becoming a common upgrade in 1991 with increases in resolution and screen size occurring frequently until the introduction of 17"-screen laptops in 2003.

4 Major brands and manufacturers There are a multitude of laptop brands and manufacturers; several major brands, offering notebooks in various classes, are listed in the box to the right. The major brands usually offer good service and support. Some brands are specializing in a particular class of laptops, such as gaming laptops (Alienware), selling high-performance laptops (HP Envy), netbooks (EeePC) and laptops for children (OLPC). Many brands, including the major ones, do not design and donot manufacture their laptops. Instead, a small number of Original Design Manufacturers design new models of laptops, and the brands choose the models to be included in their lineup. In 2006, 7 major ODMs manufactured 7 of every 10 laptops in the world, with the largest one (Quanta Computer) having 30% world market share. Therefore, there often are identical models available both from a major label and from a low- profile ODM in-house brand.
