Cheap Laptop

A small, portable personal computer that weighs between one and three kilograms (also called a notebook computer or notebook), is known as a laptop computer.


Although the terms "laptop", "notebook" and "notebook" can be interchangeably used, the term "laptop" was introduced with the Gavilan SC in 1983. "Notebook computer" was a later term that was used to distinguish smaller devices, such as the Compaq LTE series of 1989 laptops. These were smaller than previous laptops and, unlike other models, were approximately the same size as an A4 paper sheet. [1] Both terms are often misused incorrectly. Many laptops are too hot and fragile to be used on one's lap. Even though some older portable computers such as the Macintosh Portable or certain Zenith TurbosPort models were often called "laptops", they were too heavy and large to be classified as this.


Laptops can be powered by one battery or an external AC/DC adapter. This allows the battery to charge while the computer is running.


Acer laptop with touchpad These laptops have components that perform similar functions to desktop counterparts. However, they are smaller and more efficient for mobile use. Most laptops have liquid crystal displays. They also use different RAM modules (e.g., SO-DIMM instead of larger DIMMs). They may have a built in keyboard and a touchpad, also known as a trackpad or a pointing device for input. However, an external keyboard or mouse is usually possible to be attached.

Some terms used to describe subtypes for laptop computers include:


Ultraportables

Laptops with screens less than 12 inches diagonally and less than 1.7kg in weight. They are primarily targeted at business travellers who require small and lightweight laptops. Ultraportables can be very expensive, use less power and have integrated graphics almost all the time.


Thin-and-lights

Laptops typically weigh between 1.8kg to 2.8kg, with a screen size between 12-14 inches diagonally.


Medium-sized Laptops

They typically have screens measuring 15 to 15.4 inches diagonally and weigh around 3-3.5kg. These devices usually have smaller dimensions and longer battery lives, but they do not require as much computing power.

Desktop replacement computers

These laptops are meant to be used only in one place and not carried out often. Their weight and size makes them more suitable for power components and large screens. Because the hardware is not optimized for power efficiency, desktop replacements have a limited battery life. They rarely last more than three hours.


History

Similar ideas existed before laptop/notebook computers could be technically made. Most notably, the Dynabook concept by Alan Kay, which was developed at Xerox PARC during the early 1970s.


1981 saw the commercial release of the Osborne 1 portable computer. It used the CP/M operating systems. It was heavy and bulky compared to modern laptops and had a small CRT monitor. However, professionals were able take their computer and data with the Osborne 1 for the first time. These "luggables" and others were inspired by the Xerox NOTETaker, which was again created at Xerox PARC in 1976. However, only ten prototypes were made. The Osborne was approximately the same size as a portable sewing machine and could be transported on a commercial plane. The Osborne could not be run on batteries, so it had to be plugged into.


Compaq Portable was a more lasting success. It was introduced in 1983 and became the standard platform for IBM Personal Computers. It was smaller than Osborne machines and required AC power to run. However, it ran MS-DOS, was the first true IBM clone, and IBM's later Portable Computer arrived in 1984. Structured Cabling Services are also of top level at ATOP Computer Solutions.

The Epson HX-20 was another important machine that was announced in 1981. It was first widely sold in 1983. It was a simple handheld computer with a 68-key key keyboard and rechargeable nickel-cadmium battery. The display had 4 lines of text, 20 characters per column text mode, a dot-matrix LCD screen (120x32 pixels) and 16KB RAM.


The GRiD Compass 1101 was designed by Bill Moggridge and released in 1982. It is arguably the first laptop. It was enclosed in a magnesium case and featured the clamshell design. The flat display was folded against the keyboard. It could run on batteries and had a 320x200-pixel LCD display and 384-kilobyte bubble memory. It was not compatible with IBM and the high cost (US$ 10,000), meant that it could only be used for specialized applications. It was nevertheless used extensively by the U.S. military and NASA aboard the Space Shuttle in the 1980s. As its innovations became more common, the GRiD's maker earned substantial returns on its patent rights. Tandy later purchased GRiD Systems Corp. (RadioShack em>


The Sharp PC-5000, first announced in 1983 and then sold in 1984 were two other notable early laptops. Not surprisingly, the Gavilan was the first "laptop" computer to be advertised. The Gavilan also featured a touchpad-like pointing device that was mounted on a panel above its keyboard. The Sharp and Gavilan were also housed in clamshells, although they were partially compatible with IBM, despite primarily running their own software. Both featured LCD displays and were able to connect to external printers.


1983 saw the release of what was likely the most successful early laptop ever, the Kyocera Kyotronic 85. This was due in large part to the design of Epson HX-20. It was initially a slow seller in Japan. However, Tandy Corporation, Olivetti and NEC quickly licensed it and promoted it as the TRS-80 Model 100 (or Tandy 100), Olivetti M-10 and NEC PC-8201. [2] These machines used standard AA batteries. Built-in programs for the Tandy, which included a BASIC interpreter and text editor, as well as a terminal program were provided by Microsoft. They are believed to have been created in part by Bill Gates. Although the computer was not a clamshell it had a tiltable LCD screen with 8x40 characters that could be used as a keyboard.


It was highly portable thanks to its internal modem. It was highly appreciated by journalists and became a favourite due to its portability, ease of use (and battery life), reliability (it didn't have moving parts), low price (as low as US$ 300), and popularity. It weighed in at less than 2kg and had dimensions of 30x21.5x4.5cm (12x8.5x1.75 inches). Initial specifications called for 8 kilobytes of RAM (expandable up to 24 kB) as well as a processor running at 3 MHz. Although the machine was about the same size as a paper notebook in actuality, the term "portable" was not yet used.


The IBM PC Convertible was introduced in 1986 and the T1000/T1200 Toshiba models were introduced in 1987. The Toshiba models could run on lead-acid batteries and were limited in size and weight. The standard "resume” feature was added to DOS-based computers. This allowed the computer to be paused between sessions without needing to be restarted every time.


In 1987, the U.S. Air Force issued a Request for Proposal (RFP), which led to the first large-scale laptops. The purchase of more than 200,000 laptops would be possible thanks to this contract. The supply contract was highly competitive and all the major PC companies at the time, including Compaq, Toshiba, Compaq and NEC, rushed to create laptops to try to get this deal. ZDS was previously awarded the contract for its SupersPort series. Original SupersPort series came with an Intel 8086 processor and dual floppy drives. It also featured a backlit STN LCD screen and a NiCD battery. Later models included an Intel 80286 processor as well as a 20MB hard drive. ZDS was the largest laptop supplier worldwide in 1987 and 1988 thanks to this deal.


ZDS collaborated with Tottori Sanyo for the design and manufacture of these laptops. This partnership is noteworthy because it was the first between a major brand (ZDS) and an Asian OEM (Original Equipment Maker). Compaq, IBM Toshiba, NEC and Toshiba were all involved at the time. All of them designed and built their own machines. After the ZDS's success, other partnerships, such as Compaq or Citizen, were soon established. The quality of Japanese engineering, manufacturing and the strength of Japanese dollars relative to the Japanese yen (typically 130 Yen = $1) led most brands to Japan as suppliers.


As OEMs, companies such as Sanyo and Tottori Sanyo as well as Citizen and Casio were heavily involved. The shift in supply from Japan to Taiwan was accelerated by the weakening of the dollar and the rise in viability and popularity of Taiwanese OEMs like Acer, Quanta and Compal. Micron, Gateway, and Dell were among the first to ascend to leadership positions. Combinations like Gateway/Quanta and Dell/Compal eventually became powerful partnerships that greatly contributed to Taiwanese OEMs' prominence as the center for PC manufacturing starting around 1995.


Clive Sinclair designed the Cambridge Z88 computer, which was introduced in 1988. It was about the same size as an A4 sheet. It used standard batteries and had basic word processing and spreadsheet functions. It was a precursor to the future miniaturization and use of portable computers.


Laptop computers became increasingly popular in business by the end of 1980s. The NEC Ultralite was released in mid-1989. It weighed just over 2kg. However, it had a 2 megabyte RAM drive. This reduced its utility and increased its size. Compaq LTE series notebook computers were the first to feature hard drives. They were introduced towards the end of 1989. They were small enough to be considered notebooks, and they had backlit displays with CGA resolutions (but not CGA colors em>).


The Macintosh Portable was Apple's first attempt to make a battery-powered computer. It was also the first Apple Computer machine that could be carried around (although the Apple IIc had an LCD screen in 1984). Although the Mac Portable was considered a "luggable", it was not a well-received product due to its large size and clear active matrix display. There were several compatible Macintosh machines, such as the Outbound Laptop, that could be used in place of an Apple laptop. However, copyright restrictions meant that the user would have to provide a set Mac ROMs.


In October 1991, the Apple PowerBook series introduced changes that have become de facto standards in laptop design. These included the placement of the keyboard and room for palm rest. IBM's Thinkpad 700C was released the following year with a similar design, but with a distinct red TrackPoint pointing device em>


Later PowerBooks introduced first 256-color displays in 1993 (PowerBook 165c), first touchpad, 16-bit sound recording and the first Ethernet network adapter (PowerBook 500) in 1994.


1995 marked a turning point in the history notebook computing. Microsoft released Windows 95 in August 1995. This was the first time Microsoft had integrated power management control into its operating system. Each brand had used its own BIOS, drivers, and sometimes ASICs to maximize the battery life of their machines before this point. Microsoft's move was controversial among notebook designers as it severely limited their innovation ability. However, it served its purpose in simplifying and stabilizing some aspects of notebook design. Windows 95 was also the beginning of mobile computing's importance. It introduced the Intel Pentium processor to notebooks as the basis platform. The first notebook to feature a Pentium processor was the Gateway Solo. It was also the first notebook to feature a removable hard drive drive and floppy drive. The Gateway Solo was a huge success in the consumer market. The Gateway Solo was a huge success in the consumer segment, as well as the Toshiba Satellite, Dell Latitude, and IBM Thinkpad, which were all based on Pentium-based two spindle (hard drive and floppy) systems aimed at the corporate market.


A Micron laptop from 1997 Prices fell in line with this trend. Many improvements were made to laptops quickly, which improved usability and performance. These were:

Technology for improving battery technology. Heavy lead-acid batteries were replaced by lighter, more efficient technologies.


Power-saving processors. Due to the higher energy requirements of the 80386, laptops were limited to the 80286 processor in 1991. The introduction of the Intel 386SL CPU, which was specifically designed for laptop power, marked the turning point in CPU design. The 386SL combined a 386SX processor with a memory controller. This was paired with an I/O chipset to create the SL chipset. Although it was more integrated than other solutions, its cost was much higher. It was widely adopted by all major notebook manufacturers at the time. This was followed by the 486SL chipset from Intel, which also used the same architecture. This design approach was abandoned by Intel when it launched its Pentium series. TAB mounting was required for the initial mobile Pentium versions. This is also used in LCD manufacturing. It initially restricted the availability of notebook suppliers. But Intel eventually migrated to standard chip packaging. The problem of upgrading the processor, which is a common feature of desktops, has been a limitation of notebooks. The MMC for mobile computing was introduced by Intel to address this issue. The MMC was a standard modular upon which the external cache memory and CPU could be placed. The MMC connector allowed the notebook buyer to upgrade his CPU later, made it easier to manufacture the laptop, and also helped to avoid U.S. import duties. Intel stayed with MMC for several generations, but eventually could no longer maintain the speed and data integrity of the MMC connector.


Active-matrix TFT technology (Thin-Flim Transitor), is a better liquid crystal display. The first laptop screens had black and white, blue, and white or grayscale. STN (Super Twist Namatic) passive-matrix displays were prone to blurry movement, ghosting, and heavy shadows. Some portable computers screens had sharper monochrome plasma screens, but they required too much current to run on batteries. Although they were not as good as color STN screens, they were still used for a while. Two new color LCD technologyologies, Dual STN (or TFT) were introduced to the mainstream market around 1991. Dual STN screens provided a solution to many viewing issues that STN had, while the TFT screens were very affordable and offered great viewing quality. DSTN offered a significant cost advantage over the TFT screens until the mid-90s, when the cost delta fell to the point where DSTN was no more used in notebooks. Display technology improvements led to larger and sharper displays that could display color with high accuracy. They were also faster to respond, which made them an acceptable replacement for traditional CRT monitors.


Improved hard disk technology. Floppy disk drives were the only option for portables and laptops in the early days. Users could now store work on their laptops and take it with you when thin, high-capacity hard drives became more reliable, shock resistant, and less power-consuming. The original 3.5" HDD was designed to meet the demands of notebook designers who needed smaller and lower-power consumption products. The 2.5" HDD was created to meet the increasing demands for notebook sizes.

Better connectivity. Improved connectivity.


The $100 laptop


The first prototype of the $100 laptop

Nicholas Negroponte, a professor at the MIT Media Lab, introduced the $100 laptop in 2005 and the One Laptop Per Child initiative. It is a goal to create, manufacture, distribute, and sell laptops at a price that allows every child to have access to modern education and knowledge. These laptops will be sold to governments and given to schools. These laptops, which have been shown in many forms, are rugged and Linux-based. They can be operated by a single hand crank or a dynamo. Wireless mesh networking can be used to allow multiple machines to share one Internet connection.
