73-565: The ThinkPad E Series (formerly ThinkPad Edge ) is a notebook computer series produced since 2010 by Lenovo . It is the most affordable sibling in the ThinkPad family and is aimed at small business users as well as education markets. The Edge series of ThinkPad computers was introduced at the 2010 International CES in Las Vegas and became available for sale in April of the same year. It
146-447: A hard disk drive (HDD) for storage; since then, solid-state drives (SSD) have gradually come to supplant hard drives in all but some inexpensive consumer models. Solid-state drives are faster and more power-efficient, as well as eliminating the hazard of drive and data corruption caused by a laptop's physical impacts, as they use no mechanical parts such as a rotational platter. In many cases, they are more compact as well. Initially, in
219-406: A laptop or notebook , is a small, portable personal computer (PC). Laptops typically have a clamshell form factor with a flat-panel screen on the inside of the upper lid and an alphanumeric keyboard and pointing device on the inside of the lower lid. Most of the computer's internal hardware is fitted inside the lower lid enclosure under the keyboard, although many modern laptops have
292-417: A separate graphics processor were limited in their utility for gaming and professional applications involving 3D graphics, but the capabilities of CPU-integrated graphics have converged with the low-end of dedicated graphics processors since the mid-2010s. For laptops possessing limited onboard graphics capability but sufficient I/O throughput, an external GPU (eGPU) can provide additional graphics power at
365-414: A broad range of devices, which combined features of several previously separate device types. The hybrids , convertibles , and 2-in-1s emerged as crossover devices, which share traits of both tablets and laptops. All such devices have a touchscreen display designed to allow users to work in a tablet mode, using either multi-touch gestures or a stylus / digital pen . Convertibles are devices with
438-429: A built-in webcam at the top of the screen, and some even feature a touchscreen display. In most cases, unlike tablet computers which run on mobile operating systems , laptops tend to run on desktop operating systems, which were originally developed for desktop computers . The word laptop , modeled after the term desktop (as in desktop computer ), refers to the fact that the computer can be practically placed on
511-446: A device by means such as USB ; some of these may include keys not found on a standard numpad, such as a spacebar or a 00 (or 000 ) key. Sometimes it is necessary to distinguish between a key on the numpad and an equivalent key elsewhere on the keyboard. For example, depending on the software in use, pressing the numpad's 0 key may produce different results than pressing the alphanumeric 0 key. In such cases,
584-458: A few high-end models intended for gaming do as well. As of 2021, 8 GB RAM is most common, with lower-end models occasionally having 4 GB. Higher-end laptops may come with 16 GB of RAM or more. The earliest laptops most often used floppy disk for storage, although a few used either RAM disk or tape, by the late 1980s hard disk drives had become the standard form of storage. Between 1990 and 2009, almost all laptops typically had
657-405: A full-featured desktop OS like Windows 10 , and have a number of typical laptop I/O ports, such as USB 3 and Mini DisplayPort . 2-in-1s are designed to be used not only as a media consumption device but also as valid desktop or laptop replacements, due to their ability to run desktop applications, such as Adobe Photoshop . It is possible to connect multiple peripheral devices, such as
730-592: A laptop and provide display output over one USB-C Cable. Most laptop displays have a maximum refresh rate of 60 Hz. The Dell M17x and Samsung 700G7A, both released in 2011, were among the first laptops to feature a 120 Hz refresh rate, and more such laptops have appeared in the years since. A laptop's CPU has advanced power-saving features and produces less heat than one intended purely for desktop use. Mainstream laptop CPUs made after 2018 have at least two processor cores, often four cores, and sometimes more, with 6 and 8 cores becoming more common. For
803-516: A mouse, keyboard, and several external displays to a modern 2-in-1. Microsoft Surface Pro-series devices and Surface Book are examples of modern 2-in-1 detachable, whereas Lenovo Yoga -series computers are a variant of 2-in-1 convertibles. While the older Surface RT and Surface 2 have the same chassis design as the Surface Pro, their use of ARM processors and Windows RT do not classify them as 2-in-1s, but as hybrid tablets. Similarly,

#1732802582336876-742: A number of hybrid laptops run a mobile operating system , such as Android . These include Asus's Transformer Pad devices, examples of hybrids with a detachable keyboard design, which do not fall in the category of 2-in-1s. A rugged laptop is designed to reliably operate in harsh usage conditions such as strong vibrations, extreme temperatures, and wet or dusty environments. Rugged laptops are bulkier, heavier, and much more expensive than regular laptops, and thus are seldom seen in regular consumer use. The basic components of laptops function identically to their desktop counterparts. Traditionally they were miniaturized and adapted to mobile use, The design restrictions on power, size, and cooling of laptops limit
949-476: A numpad. To compensate, most such keyboards include Num Lock integrated into a function key (typically F6 or F8 ) and then press keys like 7 to produce their numpad counterpart. Ten key speed is measured in Keystrokes per Hour (KPH). The minimum required speed for many data entry jobs is around 9000 KPH with good accuracy. A speed of 12,000 is considered excellent. The numeric keypad
1022-485: A small niche market , mostly for specialized field applications, such as in the military, for accountants, or travelling sales representatives. As portable computers evolved into modern laptops, they became widely used for a variety of purposes. The history of the laptop follows closely behind the development of the personal computer itself. A "personal, portable information manipulator" was imagined by Alan Kay at Xerox PARC in 1968, and described in his 1972 paper as
1095-496: A standard for memory cards in PCs. The specification for PCMCIA type I cards, later renamed PC Cards, was first released in 1990. Displays reached 640x480 ( VGA ) resolution by 1988 ( Compaq SLT/286 ), and color screens started becoming a common upgrade in 1991, with increases in resolution and screen size occurring frequently until the introduction of 17" screen laptops in 2003. Hard drives started to be used in portables, encouraged by
1168-488: A wide range of CPUs designed for laptops available from both Intel , AMD , and other manufacturers. On non- x86 architectures, Motorola and IBM produced the chips for the former PowerPC -based Apple laptops ( iBook and PowerBook ). Between around 2000 to 2014, most full-size laptops had socketed, replaceable CPUs; on thinner models, the CPU was soldered on the motherboard and was not replaceable or upgradable without replacing
1241-398: Is a concept for a laptop that can be easily disassembled. The terms laptop and notebook both trace their origins to the early 1980s, coined to describe portable computers in a size class smaller than the contemporary mainstream units (so-called "luggables" ) but larger than pocket computers . The etymologist William Safire traced the origin of laptop to some time before 1984;
1314-407: Is also useful on Windows PCs for typing alt codes for special symbols; for example, the degree symbol, °, can be typed on these computers with the sequence Alt + 0 + 1 + 7 + 6 . To maintain their compact size, most laptops do not include a numeric keypad on their keyboard (though they can sometimes be found on larger models); even some desktop keyboards designed for compactness omit
1387-480: Is mounted, although, as of 2021, an increasing number of models use memory soldered to the motherboard, either alongside SO-DIMM slots or without any slots and soldering all memory to the motherboard, but a new form factor, the CAMM module , is slated to fix the size and timing limitation. Before 2000, most laptops used proprietary memory modules if their memory was upgradable. In the early 2010s, high end laptops such as
1460-429: Is no clear dividing line in minimum or maximum size. Machines small enough to be handheld (screens in the 6–8" range) can be marketed either as very small laptops or "handheld PCs", while the distinction between the largest laptops and "All-in-One" desktops is whether they fold for travel. Having a higher resolution display allows more items to fit onscreen at a time, improving the user's ability to multitask, although, at
1533-430: Is not unknown as of 2022, but since around 2010, the practice has been restricted to small-volume gaming models. Laptop CPUs are rarely able to be overclocked ; most use locked processors. Even on gaming models where unlocked processors are available, the cooling system in most laptops is often very close to its limits and there is rarely headroom for an overclocking–related operating temperature increase. On most laptops,

Numeric keypads are useful for entering long sequences of numbers quickly, such as in spreadsheets , financial/accounting programs, and calculators. Input in this style is similar to a calculator or adding machine . A numpad
1679-512: Is on, digit keys produce the corresponding digit. On Apple Macintosh computers, which lack a Num Lock key, the numeric keypad always produces only numbers; the Num Lock key is replaced by the Clear key. The arrangement of digits on numeric keypads with the 7 - 8 - 9 keys two rows above the 1 - 2 - 3 keys is derived from calculators and cash registers . It
1752-1848: Is powered by second and third generation Intel Core processors with Intel HD Graphics or Nvidia Graphics. Battery life is increased with Nvidia's Optimus power management technology. Dedicated keys for controlling audio and video functions, Dolby Advanced Audio rated speakers, and an optional 720p camera were added to improve the experience for users of VOIP.

The development of memory cards was driven in the 1980s by the need for a floppy-disk-drive alternative, having lower power consumption, less weight, and reduced volume in laptops. The Personal Computer Memory Card International Association (PCMCIA) was an industry association created in 1989 to promote
2482-509: The 2011 Samsung 700G7A have passed the 10 GB RAM barrier, featuring 16 GB of RAM. When upgradeable, memory slots are sometimes accessible from the bottom of the laptop for ease of upgrading; in other cases, accessing them requires significant disassembly. Most laptops have two memory slots, although some will have only one, either for cost savings or because some amount of memory is soldered. Some high-end models have four slots; these are usually mobile engineering workstations, although

It's available with the 2nd gen and
2701-569: The Edge 15 fares much worse". Reviews of the E220s and E420s were more positive, citing better build quality than other models in the Edge line. The ThinkPad Edge series uses processors from both AMD and Intel. AMD processors offered include the Athlon II dual-core, the Turion II Dual-core, Phenom II Triple-core and Ryzen 2nd, 3rd, 4th and 5th Generation mobile Accelerated Processing Units (APUs). Intel processors used include

This was introduced by Intel with the Core i-series of mobile processors in 2010, followed by similar AMD APU processors in January 2011. Before that, lower-end machines tended to use graphics processors integrated into the system chipset , while higher-end machines had a separate graphics processor. In the past, laptops lacking
2847-470: The ability to conceal a hardware keyboard. Keyboards on such devices can be flipped, rotated, or slid behind the back of the chassis, thus transforming from a laptop into a tablet. Hybrids have a keyboard detachment mechanism, and due to this feature, all critical components are situated in the part with the display. 2-in-1s can have a hybrid or a convertible form, often dubbed 2-in-1 detachable and 2-in-1 convertibles respectively, but are distinguished by
2920-465: The ability to run a desktop OS , such as Windows 10 . 2-in-1s are often marketed as laptop replacement tablets . 2-in-1s are often very thin, around 10 millimetres (0.39 in), and light devices with a long battery life. 2-in-1s are distinguished from mainstream tablets as they feature an x86 -architecture CPU (typically a low- or ultra-low-voltage model), such as the Intel Core i5 , run

Higher-end laptops intended for gaming or professional 3D work still come with dedicated (and in some cases even dual) graphics processors on the motherboard or as an internal expansion card . Since 2011, these almost always involve switchable graphics so that when there is no demand for the higher performance dedicated graphics processor, the more power-efficient integrated graphics processor will be used. Nvidia Optimus and AMD Hybrid Graphics are examples of this sort of system of switchable graphics. Traditionally,

The numpad's keys are digits 0 to 9 , + ( addition ), - ( subtraction ), * ( multiplication ), and / ( division ) symbols, . ( decimal point ), Num Lock , and ↵ Enter keys. As smaller keyboards such as those found on laptops often lack a number pad, many companies sell separate numpads that can be connected to
3285-769: The higher resolutions on smaller screens, the resolution may only serve to display sharper graphics and text rather than increasing the usable area. Since the introduction of the MacBook Pro with Retina display in 2012, there has been an increase in the availability of "HiDPI" (or high Pixel density ) displays; as of 2022, this is generally considered to be anything higher than 1920 pixels wide. This has increasingly converged around 4K (3840-pixel-wide) resolutions. External displays can be connected to most laptops, with most models supporting at least one.

From 1983 onward, several new input techniques were developed and included in laptops, including the touch pad ( Gavilan SC , 1983), the pointing stick (IBM ThinkPad 700 , 1992), and handwriting recognition (Linus Write-Top, 1987). Some CPUs, such as the 1990 Intel i386SL , were designed to use minimum power to increase the battery life of portable computers and were supported by dynamic power management features such as Intel SpeedStep and AMD PowerNow! in some designs. Some laptops in

In general, laptop components are not intended to be replaceable or upgradable by the end-user, except for components that can be detached; in the past, batteries and optical drives were commonly exchangeable. Some laptops feature socketed processors with sockets such as
3942-479: The most compact laptops, there may be no upgradeable components at all. The following sections summarize the differences and distinguishing features of laptop components in comparison to desktop personal computer parts. The typical laptop has a screen that, when unfolded, is upright to the user. Laptop screens most commonly employ liquid-crystal display (LCD) technology, although use of OLED panels has risen substantially since 2020. The display interfaces with

The panels are mainly manufactured by AU Optronics , BOE Technology , LG Display or Samsung Display . Externally, it can be a glossy or a matte (anti-glare) screen. In the past, there was a broader range of marketing terms (both formal and informal) to distinguish between different sizes of laptops. These included Netbooks , subnotebooks , Ultra-mobile PC , and Desktop replacement computers ; these are sometimes still used informally, although they are essentially dead in terms of manufacturer marketing. As of 2021, mainstream consumer laptops tend to come with 11", 13" or 15"-16" screens; 14" models are more popular among business machines. Larger and smaller models are available, but less common – there
4088-428: The motherboard. Since 2015, Intel has not offered new laptop CPU models with pins to be interchangeable, preferring ball grid array chip packages which have to be soldered; and as of 2021, only a few rare models using desktop parts. In the past, some laptops have used a desktop processor instead of the laptop version and have had high-performance gains at the cost of greater weight, heat, and limited battery life; this

4380-481: The release of the NEC UltraLite in 1988. Notebooks and laptops continued to occupy distinct market segments into the mid-1990s, but ergonomic considerations and customer preference for larger screens soon led to notebooks converging with laptops in the late 1990s. Today, the terms laptop and notebook are synonymous, with laptop being the more common term in most English-speaking territories. Since
