See also * 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. * Improved interconnectivity. Internal modems and standard serial, parallel, and PS/2 ports on IBM PC-compatible laptops made it easier to work away from home; the addition of Ethernet networking ports and, from 1997, USB, and from 1999, Wi-Fi, made laptops as easy to use with peripherals as a desktop computer. * Docking stations may be used for expanding connectors and quickly connecting many components to the laptop, although they are falling out of favour as laptops' integral capabilities increase and USB allows several peripherals to be connected through one plug. * Compaq - EVO, Armada, LTE, and Presario * Rock Direct * Most laptops are powered or recharged from an external AC converter that usually takes the form of a plain black rectangular box. These devices weigh about 500 g (about 1 lb) and often take the name "power brick."

* Averatec * iQon - Qompanion * Relion 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. 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. * Power-saving processors.

* Docking stations may be used for expanding connectors and quickly connecting many components to the laptop, although they are falling out of favour as laptops' integral capabilities increase and USB allows several peripherals to be connected through one plug. * Tablet PC 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. * Zyrex * Fujitsu Siemens - Lifebook, FMV - BiBlo Laptops generally cost more than a desktop computer of similar specification. Performance is usually lower than that of a comparable desktop because of the compromises necessary to keep weight and power consumption low. * Samsung - Sens 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.

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. * Sharp - Mebius See also Laptops usually run on batteries, but also from adapters which also charge the battery using mains electricity. * 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. * Relion 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.
