Many parts for a laptop computer are smaller, lighter, or otherwise adapted from the corresponding part in a desktop computer: * Relion * Toshiba - Dynabook, Equium, Portege, Tecra, Satellite, Qosmio, Libretto Misconceptions about laptops 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). * 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. 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: * Relion * Apple Computer - iBook, PowerBook and MacBook Pro

Similarly it is often possible to wirelessly connect a laptop using a cellphone as a modem. Infra-red, USB and Bluetooth solutions are available. The same caveats regarding price of service apply. Laptops usually run on batteries, but also from adapters which also charge the battery using mains electricity. A more enduring success was the Compaq Portable, the first product from Compaq, introduced in 1983, by which time the IBM Personal Computer had become the standard platform. Although scarcely more portable than the Osborne machines, and also requiring AC power to run, it ran MS-DOS and was the first true IBM clone. (IBM's own later Portable Computer, which arrived in 1984, was notably less IBM-compatible than the Compaq.)

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: * Power-saving processors. While laptops in 1991 were limited to the slower 80286 processor because of the energy demands of the more powerful 80386, the introduction of the Intel 386SX processor, designed for the specific power needs of laptops, marked the point at which laptop needs were included in processor design. Among the first commercial IBM-compatible laptops were the IBM PC Convertible, introduced 1986, and the Toshiba T1000 and T1200, introduced 1987. Although limited floppy-based DOS machines (the operating system was stored in ROM), the Toshiba machines were small and light enough to be carried in a backpack, and could be run off lead-acid batteries. These also introduced the now-standard "resume" feature to DOS-based machines; the computer could be paused between sessions, without having to be restarted each time. As technology improved during the 1990s, the usefulness and popularity of laptops increased while prices went down. Several developments specific to laptops were quickly implemented in their design, improving their usability and performance compared to desktop computers. Among them were:

The Apple PowerBook series, introduced in 1991, heralded many changes that are now standard on laptops, including ergonomic improvements such as the placement of the keyboard at the back of the machine, thus creating a palm rest, and the inclusion of a built-in pointing device (a trackball). The following year, IBM released its Thinkpad series, offering similar miniaturization. * Most modern laptops use an active matrix display with resolutions of 1024 by 768 pixels (XGA) and above, screen sizes 10 inch (250 mm) or larger, and have a PC-Card expansion bay for expansion cards, formerly called PCMCIA. Internal hard disks are physically smaller—2.5 inch (64 mm) compared to the standard desktop 3.5 inch (90 mm) drive—and usually have lower performance and power consumption. Display adapters and sound cards are integrated. Modern laptops can often handle sophisticated games, but tend to be limited by their fixed screen resolution and display adapter type. 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. A more enduring success was the Compaq Portable, the first product from Compaq, introduced in 1983, by which time the IBM Personal Computer had become the standard platform. Although scarcely more portable than the Osborne machines, and also requiring AC power to run, it ran MS-DOS and was the first true IBM clone. (IBM's own later Portable Computer, which arrived in 1984, was notably less IBM-compatible than the Compaq.) * Lenovo - IBM ThinkPad Two other noteworthy early laptops were the Sharp PC-5000 (1983) and the Gavilan SC, announced in 1983 but first sold in 1984. The Gavilan was notably the first computer to be marketed as a "laptop." It was also equipped with a pioneering touchpad-like pointing device, installed on a panel above the keyboard. Like the GriD Compass, the Gavilan and the Sharp were housed in clamshell cases, but they were partly IBM-compatible, although primarily running their own system software. Both had LCD displays, and had optional printers that attached to their cases. * Voodoo PC - Envy

* Averatec The first Apple Computer machine designed to be used on the go was the 1989 Macintosh Portable (although an LCD screen had been an option for the transportable Apple IIc in 1984). Another "luggable," rather than laptop, the Mac Portable was praised for its clear active matrix display and long battery life, but was a poor seller due to its bulk. In the absence of a true Apple laptop, several compatible machines such as the Outbound Laptop were available for Mac users; however, for copyright reasons, the user had to supply a set of Mac ROMs, which usually meant having to buy a new or used Macintosh as well. 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. Similarly it is often possible to wirelessly connect a laptop using a cellphone as a modem.
