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:

  • Notebooks smaller than a A4 sheet of paper and weighing around 1 kg are sometimes called sub-notebooks or subnotebooks.
  • Notebooks weighing around 5 kg are sometimes termed desknotes (desktop/notebook).
  • Powerful laptops (often heavy) designed to compete with the computing power offered by a typical desktop are sometimes known as desktop replacements.
  • Computers larger than PDAs but smaller than notebooks are also sometimes a called palmtops.

Laptops usually run on batteries, but also from adapters which also charge the battery using mains electricity.

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.

History

The Macintosh Portable, Apple's first attempt at a laptop.

Before laptop computers were technically feasible, similar ideas had been proposed, most notably Alan Kay's Dynabook concept, developed at Xerox PARC in the early 1970s.

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.

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.)

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.

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).

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.

1983 also saw the launch of what was probably the biggest-selling early laptop, the Kyocera Kyotronic 85. Although it was at first a slow seller in Japan, it was quickly licensed by Tandy Corporation, Olivetti, and NEC, who saw its potential and marketed it as the Olivetti M-10, NEC PC-8201, and [1] Radio Shack TRS-80_Model_100_line or Tandy 100. The machines ran on standard AA batteries. The Tandy's internal programs, including a BASIC interpreter, a text editor, and a terminal program, were supplied by Microsoft, and are thought to have been written in part by Bill Gates himself. The computer was not a clamshell, but provided a tiltable 8×40-character LCD screen above a full-travel keyboard. With its internal modem, it was a highly portable communications terminal. Due to its portability, good battery life (and ease of replacement), reliability (it had no moving parts), and low price (as little as US $300), the model was highly regarded, becoming a favorite among journalists. It weighed less than 2 kg (4 lb) with dimensions of 30 x 21.5 x 4.5 cm (12 x 8.5 x 1.75 inches). Initial specs included 8 kb of RAM (expandable to 24 kb) and a 3 MHz processor.

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.

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.

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 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 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.

Later PowerBooks introduced the first 256-color displays, first true touchpad, and first built-in Ethernet networking.

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:

  • 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.
  • 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 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.
  • Improved hard disk technology. Early laptops had only floppy disk drives. As thin, high-capacity hard disk drives with higher reliability and shock resistance and lower power consumption became available, users could store their work on laptop computers and take it with them.
  • 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.
A concept render of the $100 laptop

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.

Parts

Many parts for a laptop computer are smaller, lighter, or otherwise adapted from the corresponding part in a desktop computer:

  • 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 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.
  • 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.

Some parts for a modern laptop have no corresponding part in a desktop computer:

  • 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.
  • 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.
  • 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."

Upgradability

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.

Upgradability is severely limited: typically only the RAM and hard drive can be upgraded. Often the CPU can also be replaced, and sometimes video card modules are upgradable too. Many laptops also include a MiniPCI slot inside, however it is usually not intended to be utilized by the end user. Because nearly all functions are integrated into the proprietary-design mainboard theoretically to save space and power, laptops are difficult to repair and upgrade. Outright replacement of faulty parts can include the display screen, drives, daughterboards, modem, storage devices and other components, but repair costs can be high, even when feasible (low upgradability). There is not a standard for A4-size laptops.

Performance

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 tranfer 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.

Misconceptions about laptops

Despite their name, using a laptop on one's lap can be both unpleasant (due to heat from the computer, particularly from its CPU) and possibly even dangerous to the laptop, as it may overheat. It is sometimes preferable to use a laptop on a desk.

The word laptop is often spelled incorrectly as "labtop," "lab top," or "lap top."

Some computer novices assume that laptops are constantly connected to the Internet, even (for example) while located on moving vehicles. This is a myth perpetuated by many commercials, where a person is shown using the company's website from a laptop with no wires plugged into it. This is possible via Wi-Fi or related technologies, but most laptops do not maintain a constant connection to the Internet. The growth of Metropolitan area networks may render a constant connection possible in the future. However, most modern mid-range laptops have integrated WiFi, so only require a wireless router to connect to the internet; or a wireless hotspot.

However, most modern mid-range laptops have integrated WiFi, so only require a wireless router to connect to the internet; or a wireless hotspot. Within the Trust's holdings, HE&R (including the Park), is part of the Milton Hershey School Trust. The growth of Metropolitan area networks may render a constant connection possible in the future. The Park is currently run by Hershey Entertainment, a division of Hershey Entertainment and Resorts (HE&R), which is in turn wholly owned by the Hershey Trust Company. This is possible via Wi-Fi or related technologies, but most laptops do not maintain a constant connection to the Internet. Main article: Hershey Entertainment and Resorts Company. This is a myth perpetuated by many commercials, where a person is shown using the company's website from a laptop with no wires plugged into it. Groups (mostly companies) can pre-arrange catering in one of six private picnic areas inside the park.

Some computer novices assume that laptops are constantly connected to the Internet, even (for example) while located on moving vehicles. Food is available inside the park at a plethora of stands and restaurants, though prices are generally high. The word laptop is often spelled incorrectly as "labtop," "lab top," or "lap top.". A causal sitdown restaurant is located just outside the park called Tudor Grill. It is sometimes preferable to use a laptop on a desk. Bringing in food from outside isn't allowed in the park, but is allowed outside the gates, such as in the parking lot (where picnic tables are available). Despite their name, using a laptop on one's lap can be both unpleasant (due to heat from the computer, particularly from its CPU) and possibly even dangerous to the laptop, as it may overheat. In Hersheypark there are many dining options.

This still existent difference in performance continues to be minimized. Sunshine laws apply to township meetings. While desktops continue to outperform notebooks at the high end, both types of systems generally offer sufficient performance for the mainstream. Another reason is because approval must be given by Derry Township, Dauphin County, PA to build other rides in the park. These new technologies take time to tranfer over to the laptop market because of its smaller package. Several plans have been released: usually to promote the park for the following season. Desktops have outperformed mobile computers because new technologies expend more heat. Future plans for Hersheypark remain closely guarded secrets of the company.

Laptop performance has been inferior to desktops for the same price. Besides the coasters, Hersheypark has other rides ranging from kiddie rides to thrill rides. There is not a standard for A4-size laptops. Hersheypark also had three other coasters that are no longer existing. Outright replacement of faulty parts can include the display screen, drives, daughterboards, modem, storage devices and other components, but repair costs can be high, even when feasible (low upgradability). Hersheypark has ten roller coasters of varying types. Because nearly all functions are integrated into the proprietary-design mainboard theoretically to save space and power, laptops are difficult to repair and upgrade. The week of Christmas, the park is open every day of the week 5-9.

Many laptops also include a MiniPCI slot inside, however it is usually not intended to be utilized by the end user. Christmas Candylane: Usually starts the Friday before Thanksgiving, and is open Thursday, Friday, Saturday and Sunday, with the exception of the day before Thanksgiving. Often the CPU can also be replaced, and sometimes video card modules are upgradable too. Halloween in Hershey: Open various hours, Friday, Saturday, and Sunday the last three weekends in October. Upgradability is severely limited: typically only the RAM and hard drive can be upgraded. Some weekdays: 9-8 Some Fridays: 5-10 Some Saturdays: 9-10 Some Sundays: 9-8.

In addittion, guests can "preview" the park by coming with pre-purchased tickets two hours before close; tickets are stamped but can be used again for a full day at a later date. The pricing goal is to start at $100 and then steadily decrease. Multi-day, package, and half-day admission plans are also available.

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. Carousel Circle, the initial redevelopment of the 1970s renovations of Hershey Park into HersheyPark, was remodeled into Founders Circle, in honor of the founder, Milton S.

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. In 2005, Giant Wheel was removed and replaced by two classic, rides Balloon Flite and Starship America. Among them were:. A 65-foot spinning pendulum ride called The Claw was added in 2003. Several developments specific to laptops were quickly implemented in their design, improving their usability and performance compared to desktop computers. This brings the park’s roller coaster count to ten. As technology improved during the 1990s, the usefulness and popularity of laptops increased while prices went down. In the new millennium, three coasters were added to Hersheypark – Lighting Racer (2000), Roller Soaker (2002), and Storm Runner (2004).

Later PowerBooks introduced the first 256-color displays, first true touchpad, and first built-in Ethernet networking. These include the Merry Derry Dip Fun Slide, Music Express, Chaos, and the Frog Hopper. The following year, IBM released its Thinkpad series, offering similar miniaturization. Four other new rides were added in 1999. 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). A Ferris wheel and Whip ride were added in 1997. 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. In 1994the water plunge ride the Tidal Force opened.

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. Several rides were also added during this decade. 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). Wild Mouse opened in 1999. Truly the size of a notebook, they had hard drives and standard-resolution screens. The Great Bear opened in 1998, the park's most expensive single ride to date. The first notebook computers with standard drives were the Compaq LTE series, introduced toward the end of that year. In 1996, the wooden coaster The Wildcat was added and was named after The Wild Cat that previously operated from 1923 to 1946.

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. Sidewinder, a Vekoma boomerang coaster, was added in 1991. By the end of the 1980s, laptop computers were becoming popular among business people. Four roller coasters were added to Hersheypark in the 1990s. 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. The Flying Falcon replaced Himalaya, and three kiddie rides replaced the Coal Shaker. About the size of an A4 sheet of paper, it ran on standard batteries, and contained basic spreadsheet, word processing, and communications programs. The old penny arcade was replaced by a massive three-story building, housing the Minetown Arcade, Minetown Restaurant, and games.

Another notable computer was the Cambridge Z88, designed by Clive Sinclair, introduced in 1988. The 1990s started off with the creation of Minetown. 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. Canyon River Rapids was added in 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. They include Cyclops (replaced by The Claw), Pirate, Wave Swinger, Conestoga (since removed), and Timber Rattler (replaced by Rodeo). Among the first commercial IBM-compatible laptops were the IBM PC Convertible, introduced 1986, and the Toshiba T1000 and T1200, introduced 1987. Smaller sized rides were added during the 1980s.

Initial specs included 8 kb of RAM (expandable to 24 kb) and a 3 MHz processor. Twin Toboggans was removed in 1978. It weighed less than 2 kg (4 lb) with dimensions of 30 x 21.5 x 4.5 cm (12 x 8.5 x 1.75 inches). The first steel looping roller coaster on the East Coast called the Sooperdooperlooper opened on July 4, 1977. Due to its portability, good battery life (and ease of replacement), reliability (it had no moving parts), and low price (as little as US $300), the model was highly regarded, becoming a favorite among journalists. A one-price admission plan eliminated the pay-as-you-ride policy. With its internal modem, it was a highly portable communications terminal. A five-year redevelopment plan was started in 1971 to convert the regional amusement park Hershey Park into a large theme park called Hersheypark.

The computer was not a clamshell, but provided a tiltable 8×40-character LCD screen above a full-travel keyboard. The Dry Gulch Railroad was added in 1960. The Tandy's internal programs, including a BASIC interpreter, a text editor, and a terminal program, were supplied by Microsoft, and are thought to have been written in part by Bill Gates himself. Twin 66-foot-high Ferris wheels were added in 1950. The machines ran on standard AA batteries. In 1946 the wooden roller coaster The Comet replaced The Wild Cat. Although it was at first a slow seller in Japan, it was quickly licensed by Tandy Corporation, Olivetti, and NEC, who saw its potential and marketed it as the Olivetti M-10, NEC PC-8201, and [1] Radio Shack TRS-80_Model_100_line or Tandy 100. The Dentzel carousel was replaced in 1945 by a carousel built by the Philadelphia Toboggan Company in 1919, which still operates in the park today.

1983 also saw the launch of what was probably the biggest-selling early laptop, the Kyocera Kyotronic 85. More attractions were added to Hershey Park each season, and by 1945 the park contained more than two dozen rides. Both had LCD displays, and had optional printers that attached to their cases. Renovations were made to the Wild Cat roller coaster in 1935 to build up the dips and to more steeply bank the curves. 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. A penny arcade, a fun house called The Bug, and The Mill Chute log flume ride were added in 1933. 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. A small Ferris wheel, the Aeroplane Swing, and the Skooter were added to the park during the 1920s.

Two other noteworthy early laptops were the Sharp PC-5000 (1983) and the Gavilan SC, announced in 1983 but first sold in 1984. A new roller coaster called The Wild Cat was added in 1923. GRiD Systems Corp was later bought by Tandy (RadioShack). Added to the park were the dance pavilion Starlight Ballroom, a new stage for big bands, a new Convention Hall (now the Hershey Museum), the Hershey Park Cafe, and the Hershey Zoo. The GRiD company subsequently earned significant returns on its patent rights as its innovations became commonplace. Several structures were built from 1913 to 1923. military, and was used on the Space Shuttle during the 1980s. The carrousel was described as the “most magnificent and up-to-date carousel in this part of the country as well as one of the largest.”.

However, it was used heavily by the U.S. The carousel was 50 feet in diameter and featured 53 carved animals that included lions, bears, giraffes, pigs, rabbits, an ostrich, goats, and deer along with two chariots. It was not IBM-compatible, and its high price (US$ 10,000) meant that it was limited to specialized applications. Dentzel of Philadelphia was added to the park. The computer could be run from batteries, and was equipped with a 320×200-pixel plasma display and 384-kilobyte bubble memory. In July 1912, a carousel built by William H. Enclosed in a magnesium case, it introduced the now familiar clamshell design, in which the flat display folded shut against the keyboard. Guests could also enjoy a relaxing scenic ride on the Scenic Railroad.

However, arguably the first true laptop was the GRiD Compass 1101, designed by Bill Moggridge in 1979, and released in 1982. The entrance sign proclaimed, “Ye who enter here leave dull cares behind.” The park was expanded in 1909 with the addition of a tennis court, two bowling alleys, a large band shell, and a photography gallery. While it was made to be used upon one's lap, it weighed 150 pounds, and therefore could not be deemed truly portable. A 1,500-seat tiered amphitheatre was built next to the pavilion. Another claim to be the "first laptop" was made by a novice programmer Thomas Kelly in 1982. A merry-go-round was installed and opened on July 4, 1908. (IBM's own later Portable Computer, which arrived in 1984, was notably less IBM-compatible than the Compaq.). Vaudeville and theatre productions were performed on a rustic bandstand and pavilion.

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. The beautifully landscaped park was an ideal spot for picnicking, boating, and canoeing. 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. Hershey Park opened on April 24, 1907, with a baseball game played on the new athletic field. However, it was not possible to run the Osborne on batteries; it had to be plugged in. In 1903, he surveyed a site along Spring Creek that would be suitable for his park. The Osborne was about the size of a portable sewing machine, and importantly could be carried on a commercial aircraft. Hershey, founder of the Hershey chocolate company, wanted to create a park for Hershey employees to relax when they weren't on the job.

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. Milton S. 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. . The first commercially available portable computer was the Osborne 1 in 1981, which used the CP/M operating system. Both Chocolate World and ZOOAMERICA are able to be accessed from outside the park boundaries, with Chocolate World offering free admission. Before laptop computers were technically feasible, similar ideas had been proposed, most notably Alan Kay's Dynabook concept, developed at Xerox PARC in the early 1970s.

Junior (ages 3-8): $23.95. 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). Regular (ages 9-54): $40.95. Improved liquid crystal display design, in particular active-matrix display technology, and increasingly, color screens.

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. Power-saving processors. 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. Improved battery technology.

Computers larger than PDAs but smaller than notebooks are also sometimes a called palmtops. Powerful laptops (often heavy) designed to compete with the computing power offered by a typical desktop are sometimes known as desktop replacements. Notebooks weighing around 5 kg are sometimes termed desknotes (desktop/notebook). Notebooks smaller than a A4 sheet of paper and weighing around 1 kg are sometimes called sub-notebooks or subnotebooks.
