* Clevo Another claim to be the "first laptop" was made by a novice programmer Thomas Kelly in 1982. While it was made to be used upon one's lap, it weighed 150 pounds, and therefore could not be deemed truly portable. * Compaq - EVO, Armada, LTE, and Presario * Alienware - Area 51m, Sentia and Aurora m series * PDA However, arguably the first true laptop was the GRiD Compass 1101, designed by Bill Moggridge in 1979, and released in 1982. Enclosed in a magnesium case, it introduced the now familiar clamshell design, in which the flat display folded shut against the keyboard. The computer could be run from batteries, and was equipped with a 320×200-pixel plasma display and 384-kilobyte bubble memory. It was not IBM-compatible, and its high price (US$ 10,000) meant that it was limited to specialized applications. However, it was used heavily by the U.S. military, and was used on the Space Shuttle during the 1980s. The GRiD company subsequently earned significant returns on its patent rights as its innovations became commonplace. GRiD Systems Corp was later bought by Tandy (RadioShack). Laptops usually run on batteries, but also from adapters which also charge the battery using mains electricity.

* Clevo * PDA * Notebook * Improved battery technology. The heavy lead-acid batteries were replaced with lighter and more efficient technologies, first nickel metal hydride (NiMH) and then lithium ion and lithium polymer. Laptops are capable of many of the same tasks that desktop computers perform, although they are typically less powerful for the same price. Laptops contain components that are similar to those in their desktop counterparts and perform the same functions but are miniaturized and optimized for mobile use and efficient power consumption. Laptops usually have liquid crystal displays and use SO-DIMM (Small Outline DIMM) modules (rather than the larger DIMMs used in desktop computers) for their RAM. In addition to a built-in keyboard, they may utilize a touchpad (also known as a trackpad) or a pointing stick for input, though an external mouse or keyboard can usually be attached. However this may not remain a misconception for long. Some newer laptops, for example Sony VAIO ultraportables, come with GSM cellphone-based wireless networking capablities, and it is possible to buy add-on PC card GSM modems which provide the same functionality for machines not so equipped. With these, a form of wireless broadband networking is available wherever there is cellphone coverage. Although this is much touted as an ideal business solution, the 'broadband' speeds are low compared to wired connections and the service is prohibitively expensive for most users at the time of writing (1Q 2006). In the US, wireless broadband offered by Cingular and Verizon starts at around $500 for a year with a minimum 2-year contract and each block of data transferred attracts a charge. Unlimited data plans are available but they would normally only appeal to corporate users. * iQon - Qompanion

Laptop performance has been inferior to desktops for the same price. Desktops have outperformed mobile computers because new technologies expend more heat. These new technologies take time to transfer over to the laptop market because of its smaller package. While desktops continue to outperform notebooks at the high end, both types of systems generally offer sufficient performance for the mainstream. This still existent difference in performance continues to be minimized. A laptop computer (also known as notebook computer) is a small mobile personal computer, usually weighing from 1 to 3 kilograms (2 to 7 pounds). Terms for subtypes of notebooks (and related computer types) include: Some parts for a modern laptop have no corresponding part in a desktop computer: * Bacoc * Relion In 2005, faculty members from the MIT Media Lab including Nicholas Negroponte introduced the $100 laptop as part of the One Laptop Per Child project. The aim is to design, manufacture, and distribute laptops that are sufficiently inexpensive to provide every child in the world access to knowledge and modern forms of education. The laptops will be sold to governments and issued to children by schools on a basis of one laptop per child. These machines will be rugged, Linux-based, and so energy efficient that hand-cranking alone will generate sufficient power for operation. Ad-hoc wireless mesh networking may be used to allow many machines Internet access from one connection. The pricing goal is to start at $100 and then steadily decrease. By the end of the 1980s, laptop computers were becoming popular among business people. The NEC Ultralite, released in mid-1989, was perhaps the first notebook computer, weighing just over 2 kg; in lieu of a floppy or hard drive, it contained a 2-megabyte RAM drive, but this reduced its utility as well as its size. The first notebook computers with standard drives were the Compaq LTE series, introduced toward the end of that year. Truly the size of a notebook, they had hard drives and standard-resolution screens. * Improved battery technology. The heavy lead-acid batteries were replaced with lighter and more efficient technologies, first nickel metal hydride (NiMH) and then lithium ion and lithium polymer.

* Current models use lithium ion batteries, which have largely replaced the older nickel metal-hydride technology. Typical battery life for most laptops is two to five hours with light-duty use, but may drop to as little as one hour with intensive use. Batteries gradually degrade over time and eventually need to be replaced, depending on the charging and discharging pattern, from one to five years. The first commercially available portable computer was the Osborne 1 in 1981, which used the CP/M operating system. Although it was large and heavy compared to today's laptops, with a tiny CRT monitor, it had a near-revolutionary impact on business, as professionals were able to take their computer and data with them for the first time. This and other "luggables" were inspired by what was probably the first portable computer, the Xerox NoteTaker, developed at Xerox PARC in 1976; however, only ten prototypes were built. The Osborne was about the size of a portable sewing machine, and importantly could be carried on a commercial aircraft. However, it was not possible to run the Osborne on batteries; it had to be plugged in. * LG - XNOTE * iQon - Qompanion * iQon - Qompanion * Gericom * Notebook
