* 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. 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. Another notable computer was the Cambridge Z88, designed by Clive Sinclair, introduced in 1988. About the size of an A4 sheet of paper, it ran on standard batteries, and contained basic spreadsheet, word processing, and communications programs. Although it anticipated the future miniaturization of the portable computer, as a ROM-based machine with a small display it can — like the TRS-80 Model 100 — also be seen as a foreruner of the PDA. * Sager - NP series * Averatec * Gateway * Improved liquid crystal display design, in particular active-matrix display technology, and increasingly, color screens. Early laptop screens were black and white or grayscale passive-matrix LCD displays prone to heavy shadows and blurry movement (some portable computer screens were sharper monochrome plasma displays, but these drew too much current to be powered by batteries). Improvements in production technology meant displays became larger, sharper, had higher display resolution, and could display color with great accuracy, making them an acceptable substitute for a traditional CRT monitor. 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.

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. * 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. * Panasonic - Toughbook,Let's Note(Available only in Japan)

* Notebook processor: There are a wide range of notebook processors available from Intel (Pentium M (with Centrino technology), Celeron, Intel Core Duo and Centrino Duo) and from AMD (Athlon, Turion 64, and Sempron). Motorola and IBM develop and manufacture the PowerPC chips for Apple notebooks. Generally, notebook processors are less powerful than their desktop counterparts, owing to the need to conserve electricity and reduce heat output. However, the PowerPC G3 and G4 processor generations have been able to offer almost the same performance as their desktop versions, limited mostly by lower performance in other parts of the system bus bandwidth and peripheral units) in Apple's notebooks; recently, though, with the introduction of the G5s, they have been far outstripped. At one point, the Pismo G3, at up to 500 MHz, was faster than the fastest desktop G3 (then the B&W G3), which ran at 450 MHz. 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:
