The Following list summarizes the differences and distinguishing features of a laptop Components in comparison to desktop personal computer parts:

Central Processing unit (CPU): Laptop CPUs have advanced power-saving features and Produce less heat than desktop processors, but are not as powerful. There is a Wide range of CPUs designed for laptops available from Intel (Pentium M, Celeron M, Intel Core, Core 2 Duo) and Intel Atom; AMD (Athlon, Turion 64, and Sempron); VIA Technologies, Transmeta and others. On non-x86 architectures, Motorola and IBM produced the chips for the former PowerPC-based Apple laptops (IBook and PowerBook). Most laptops have removable CPUs, although the A motherboard may restrict the processor to the specific models, limiting the Processors that are compatible. Some laptops use a desktop processor instead of The laptop version and have high performance gains at the cost of the potential For overheating problems, and less battery life. In other laptops the CPU is Soldered on the motherboard and is non-replaceable.

A SODIMM memory module

Memory (RAM): SO-DIMM memory modules that are usually found in laptops are about half the size of desktop DIMMs. They may be accessible from the bottom of the laptop for ease of upgrading, or placed in locations not intended for user replacement such as between the keyboard and the motherboard. Currently, most mid-range laptops are factory equipped with 3–4 GB of DDR2 RAM, while some higher end notebooks (usually mobile engineering workstations) feature up to 32 GB of DDR3 memory. Netbooks are commonly equipped with only 1 GB of RAM and generally only expandable to 2 GB, if at all, to keep manufacturing costs low.

Typical modern convertible laptops have a complex joint between the keyboard housing and the display permitting the display panel to swivel and then lay flat on the keyboard housing.

Typically, the base of a tablet laptop attaches to the display at a single joint called a swivel hinge or rotating hinge. The joint allows the screen to rotate through 180° and fold down on top of the keyboard to provide a flat writing surface. This design, although the most common, creates a physical point of weakness on the laptop.

http://www.chiptroniks.com

Some manufacturers have attempted to overcome these weak points by adopting innovative methods such as a sliding design in which the screen slides up from the slate-like position and locks into place to provide the laptop mode. Newer iterations of tablet laptops are of hybrid design. Hybrid tablets incorporate a removable keyboard base allowing the user to easily choose between functioning as a laptop with the keyboard attached or as a slate device utilizing the touch screen alone.

Although Tablets are touchscreen (with or without a stylus) they have the advantage to offer the keyboard and pointing device (usually a trackpad) of older laptops, for users who do not use the touchscreen display as the primary method of input.

A subnotebook or ultraportable is a laptop designed and marketed with an emphasis on portability (small size, low weight and often longer battery life) that retains performance close to that of a standard notebook. Subnotebooks are usually smaller and Laptop Repairing, weighing between 0.8 and 2 kg (2 to 5 pounds); the battery life can exceed 10 hours when a large battery or an additional battery pack is installed. Since the introduction of netbooks, the line between Subnotebooks and higher-end notebooks has been substantially blurred.

To achieve the size and weight reductions, ultraportables use 13" and smaller screens (down to 6.4"), have relatively few ports ( but in any case included two or more USB ports), employ expensive components designed for minimal size and best power efficiency, and utilize advanced materials and construction methods. Most Subnotebooks achieve a further portability improvement by omitting an optical/removable media drive; in this case they may be paired with a docking station that contains the drive and optionally more ports or an additional battery.

The term "subnotebook" is reserved to laptops that run general-purpose desktop operating systems such as Windows, Linux or Mac OS X, rather than specialized software such as Windows CE, iOS, Palm OS or Internet Tablet OS.

At Computex 2011 Intel announced a new class for ultraportables called Ultrabooks. The term is used to describe a highly portable laptop that has strict limits for size, weight, battery life, and have tablet-like features such as instant on functionality. Intel estimates that by the end of 2012, 40 percent of the consumer laptop market segment will be Ultrabooks.

The term "laptop repairing Course" can refer to a number of classes of Large Laptop Course

Chiptroniks: Full-size Laptop: A laptop large enough to accommodate a "full-size" keyboard (a keyboard with the minimum QWERTY key layout, which is at least 13.5 keys across that are on ¾ (0.750) inch centers, plus some room on both ends for the case). The measurement of at least 11 inches across has been suggested as the threshold for this class. The first laptops were the size of a standard U.S. "A size" notebook sheet of paper (8.5 × 11 inches), but later "A4-size" laptops were introduced, which were the width of a standard ISO 216 A4 sheet of paper (297 mm, or about 11.7 inches), and added a vertical column of keys to the right and wider screens. It can also be laid sideways when not in use.

Netbook: A smaller, lighter, more portable laptop. It is usually cheaper than a full-size laptop, but sometimes has fewer features and less computing power. The smaller keyboards of a notebook can be more difficult to operate. There is no sharp line of demarcation between netbooks and inexpensive small laptops; some 11.6" models are marketed as netbooks. Since notebook laptops are quite small in size and designed to be light and inexpensive they typically do not come with an internal optical drive. The Asus Eee PC launched this product class, while the term was coined later by Intel.

    Tablet PC: These have touch screens. There are "convertible tablets" with a full keyboard where the screen rotates to be used atop the keyboard, a "hybrid tablet" where the keyboard can be detached from the screen, and "slate" form-factor machines which are usually touchscreen only (although a few older models feature very small keyboards along the sides of the screen.)

    Ultra-mobile PC: An ultra-mobile PC (ultra-mobile personal computer or UMPC) is a small form factor version of a pen computer, a class of laptop whose specifications were launched by Microsoft and Intel in spring 2006. Sony had already made a first attempt in this direction in 2004 with its Vaio U series, which was only sold in Asia. UMPCs are smaller than Subnotebooks, have a TFT display measuring (diagonally) about 12.7 to 17.8 cm, and are operated like tablet PCs using a touchscreen or a stylus. This term is commonly (if inaccurately) used for small notebooks and/or netbooks.

    Handheld PC: A Handheld PC, or H/PC for short, is a term for a computer built around a form factor which is smaller than any standard laptop computer. It is sometimes referred to as a Palmtop. The first handheld device compatible with desktop IBM personal computers of the time was the Atari Portfolio of 1989. Other early models were the Pocket PC of 1989 and the Hewlett Packard HP 95LX of 1991. Other DOS compatible handheld computers also existed.

    Rugged: Engineered to operate in tough conditions (mechanical shocks, extreme temperatures, wet and dusty environments, etc.)

    Ultrabook: A very thin version of a laptop usually less than an inch thick. Most versions of Ultrabooks contain SSD, or Solid-State Drives, instead of the common Laptop Hard Disk Drives. Although this term (like Netbook) was coined and popularized by Intel, one of the most prominent examples is Apple's MacBook Air.

Desktop replacement[edit]

Main article: Desktop replacement computer

A desktop-replacement computer is a laptop that provides all of the capabilities of a desktop computer, with a similar level of performance. Desktop replacements are usually larger and heavier than standard laptops. They contain more powerful components and have a 15" or larger display. They are bulkier and not as portable as other laptops, and their operation time on batteries is typically shorter; they are intended to be used as compact and transportable alternatives to a desktop computer.

Some laptops in this class use a limited range of desktop components to provide better performance for the same price at the expense of battery life; a few of those models have no battery. In the early 2000s, desktops were more powerful, easier to upgrade, and much cheaper than laptops, but in later years laptops have become much cheaper and more powerful than before, and most peripherals are available in laptop-compatible USB versions which minimize the need for internal add-on cards.

History of laptops

Alan Kay with "Dynabook" prototype (5 November 2008 in Mountain View, California)
The Epson HX-20

As the personal computer (PC) became feasible in the 1970s, the idea of a portable personal computer followed. A "personal, portable information manipulator" was imagined by Alan Kay at Xerox PARC in 1968, and described in his 1972 paper as the "Dynabook".

The IBM Special Computer APL Machine Portable (SCAMP), was demonstrated in 1973. This prototype was based on the IBM PALM processor (Put All Logic in Microcode or 128 bits).

The IBM 5100, the first commercially available portable computer, appeared in September 1975, and was based on the SCAMP prototype.

As 8-bit CPU machines became widely accepted, the number of portables increased rapidly. The Osborne 1, released in 1981, used the Zilog Z80 and weighed 23.6 pounds (10.7 kg). It had no battery, a 5 in (13 cm) CRT screen, and dual 5.25 in (13.3 cm) single-density floppy drives. In the same year the first laptop-sized portable computer, the Epson HX-20, was announced. The Epson had an LCD screen, a rechargeable battery, and a calculator-size printer in a 1.6 kg (3.5 lb) chassis. Both Tandy/RadioShack and HP also produced portable computers of varying designs during this period.

The first laptops using the flip form factor appeared in the early 1980s. The Dulmont Magnum was released in Australia in 1981–82, but was not marketed internationally until 1984–85. The US$8,150 (US$19,390 today) GRiD Compass 1100, released in 1982, was used at NASA and by the military among others. The Gavilan SC, released in 1983, was the first computer described as a "laptop" by its manufacturer. From 1983 onward, several new input techniques were developed and included in laptops, including the touchpad (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 battery life of portable computers, and were supported by dynamic power management features such as Intel SpeedStep and AMD PowerNow! in some designs.

Displays reached VGA resolution by 1983 (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 the introduction of 3.5" drives in the late 1980s, and became common in laptops starting with the introduction of 2.5" and smaller drives around 1990; capacities have typically lagged behind physically larger desktop drives. Optical storage, read-only CD-ROM followed by writeable CD and later read-only or writeable DVD and Blu-ray, became common in laptops early in the 2000s

Laptop Repairing Course Detail and Laptop Details

A laptop is a portable personal computer with a clamshell form factor, suitable for mobile use. A laptop has most of the same components as a desktop computer, including a display, a keyboard, a pointing device such as a touchpad (also known as a trackpad) and/or a pointing stick, and speakers into a single unit. A laptop is powered by mains electricity via an AC adapter, and can be used away from an outlet using a rechargeable battery. Laptops are also sometimes called notebook computers or notebooks. Other terms, such as ultrabooks or notebooks, refer to specific types of laptop / notebook. Most of the modern day laptop computers also have a webcam and a mic (microphone) pre-installed.

Portable computers, originally monochrome CRT-based and developed into the modern laptops, were originally considered to be a small niche market, mostly for specialized field applications such as the military, accountants and sales representatives. As portable computers became smaller, lighter, cheaper, more powerful and as screens became larger and of better quality, laptops became very widely used for all sorts of purposes.
