subject: The most common of these models is the first choice for most notebook users potential [print this page] Notebook Computer, referred to as the NB, also known as notebook computer or laptop, is a small, portable personal computer, usually weight 1-3 kg. The current trend is smaller and smaller, more light weight, and functions have become more powerful. In order to reduce the size, notebook computers usually have liquid crystal display (also known as LCD screen LCD). In addition to the keyboard away, and some also equipped with touch pad (touchpad) or touch point (pointing stick) as a positioning device (Pointing device).
Similar words are portable computers (the Internet), more mainstream, including Asus and easy access of the PC, Acer's Aspire one, Lenovo S9, S10, Fujitsu U2010, Jin Weier of K98, Superman S30, Core Pacific's PC -210, Malata, etc.

Notebook Categories
According to cheap laptop the notebook size, weight and positioning, can generally be divided into the notebook desktop replacement, mainstream type, thin, ultra-portable, mini-notebooks and tablet PCs (Tablet PC) six.
Desktop replacement
Most laptops have this kind of performance, hardware configuration from the point of view, comparable with the high-end desktop processors are generally the use of frequency over the 3GHz Pentium 4, Mobile Pentium 4 processor, Or is the latest high-frequency Pentium M processor (2GHZ above).
G-level memory; 80G more high-speed hard drive; the highest standard notebook with a dedicated graphics card (such as: ATi Mobility Radeon X800 or nVidia Geforce go 6800Ultra, etc.); 15-inch or larger LCD screen display; one or more built-in optical drive, etc. .
But for performance improvements, the user is required to pay at a price, so the attendant is the large volume, large weight and high heat, and as large in size and weight of the heavy's sake, but also caused the portability of such models relatively poor.
Such models are not uncommon in the Chinese market: Sony A59, TCL S800, HP ZD8003, DELL I9300, etc., but in foreign countries, VOODOO PC, DELL XPS, XPS2 are typical desktop replacement. For such models, and graphics computing power for very high performance requirements of game players, or professionals in the graphic design is more suitable.
Mainstream
The most common of these models is the first choice for most notebook users potential. Speaking from the configuration to meet various needs, business, office, entertainment, video and other functions of the integration is already very mature. From the portability point of view, the relative weight and mature appropriate development die, allowing users more convenient.
With the mainstream configuration, and in size, weight, battery life will find a balance area to meet the diverse needs of everyday applications. On the screen, these laptops are generally equipped with 12 inch -15 inch screen (widescreen, non-widescreen). , The external drive can be selected.
Such models for calculating the combination of performance and portability point of moderation is better, but considering the overall price-performance factors, performance will naturally be compared with the high-end models, which still need to remind you to buy the various considerations, their needs is the most important.
Thin
Such models have many major brands, do not do too much in this introduction. Such models, mainly for the pursuit of cost or performance and portability for demanding business users.
This is between mainstream models and types between the mini-notebook, from the Chinese market, this level is still very market models. Thin body, long time life, decent entertainment business performance, excellent design process, has attracted many white-collar class.
Admittedly, the cost of portable notebook overall performance is reduced. Under normal circumstances the class notebook with processor manufacturers are less than the mainstream products specially designed low-voltage processors, frequency will be relatively low, but the power consumption and heat is entirely suitable for ultra-thin notebook design .
While in other parts, in order to meet the design requirements, such as memory, hard disk manufacturers like accessories will choose a lower power consumption and product specifications. And very few of these laptops have built-in optical drive, if the user needed to be equipped with external products. Screen in general, most of these models is equipped with 11-inch -14 inch LCD display.
ASUS S5N, Amoi T30, T31, Sony TX series notebooks are the representatives of these, although their laptop computer respective position, parameter, process, ideas are different. Thin portable is its greatest advantage, but the performance is relatively weak and relatively poor scalability. Mainly for notebook users who just handle e-mail, Internet browsing and simple document / data processing extensively and is often full of carrying notebooks business users running everywhere.
As the name suggests, mini notebook. Such a compact body makes wonder its application, in fact, nothing to worry about in the daily operations and basic business operations, mini-notebook market is still very large.
Internet
This class has a super-small notebook size, performance of basic and ultra-thin notebooks the weakest performance of the products are equivalent, but the relative ultra-thin and light notebooks lighter weight, generally with a 12-inch LCD screen below the market now see the largest screen of 12.1 inches; when the size of less than 10 inches, called the UMPC; less than 5 inches, called MID. Most netbooks come with Intel Atom N270/N280 CPU, some will choose other core Atom and VIA's China.
Portability is definitely the biggest advantage of such a notebook, but the relatively poor performance and poor scalability, let in a rather awkward position. PDA and ultra-thin notebook mini notebook before and after the attack to some frustration.
More buyers will use it as a similar function to use the PDA, ASUS S200N, SONY U8C, Fujitsu P1120, are all representatives of such products. Note that, although the overall performance is not good, but the design process and the positioning of these are high-end, the price comparable with high-end mainstream notebooks.
Tablet PC
This is the joint 7 BILL GATES known notebook manufacturers, and predicted that the Tablet PC will become the mainstream, still has not completed its intended target. Then the notebook alternative, what is the extent of the market potential?
Tablet PC hardware itself has two basic styles, one for keyboard with integrated rotating type, commonly known as Variable Tablet PC; the other is flat-plate (may need to select whether to use the keyboard), commonly known as flat Tablet PC. Both the variable type or a flat-screen Tablet PC's are supported by full-screen handwriting, which not only can be used for normal text input, but also can be achieved through it to create, edit, organize, and search is often recorded on paper handwritten notes and drawings.
In size, variable-style Tablet PC with touch LCD screen ranging from 10 inches -14 inches, while the flat type are commonly used Tablet PC 10-inch -12 inch touch LCD screen. Support handwriting, using a laptop computer that lets users change the way, with flat and variable in two ways for users to choose, and the function and mobility are not any less.
While the future of TPC Tablet PC is not very clear, and the price does not have any advantage. But its easy to use user-friendly design concept or to attract a large number of high-end business users. LG LT20, Fujitsu T4010, are all typical.
Composition notebook
Shell
Shell in addition to outward appearance is more for the desktop computer to play the role of the internal protection devices. More popular shell material: plastic, magnesium alloy, carbon fiber composite materials (carbon fiber reinforced plastic). Which the carbon fiber composite shell extension of both engineering plastics and magnesium alloy low density and high stiffness and shielding, the shell material is more excellent. General hardware vendor indicated that the shell material is the surface material on the laptops, hand care and the bottom part of the customary use of engineering plastics.
LCD screen (LCD)
Beginning from the birth of laptop LCD screen to start using as its standard output device, the classification generally are: STN, TFT liquid crystal display (TFT) and so on. Present a more civil level of the LCD screen has excellent Sharp (SHARP) the company's "super-black crystal" and Toshiba's "low-temperature polysilicon," and so on, these two are the thin film transistor liquid crystal display (TFT) LCD screen. In addition to off-screen LCD screen is also very important light-emitting devices, low-quality LCD screen lamp will make the color temperature deviation very serious (mostly yellow or red.)
Processor
Microprocessor (or CPU) works in conjunction with the operating system to control the operation of the computer. It's like the computer's brain. CPU will generate a lot of heat, so the desktop through the air circulation fan and heat sink (from the floor, consisting of channels and cooling fins system for take away the heat generated by the processor) to cool the temperature of various components. Since very little room inside the laptop can not use these cooling methods, so it's CPU is usually:
* Has a lower operating voltage and clock frequency - this can reduce the heat, while reducing power consumption, but also reduce the processor speed. In addition, plug in an external power supply, the most notebook computer to a high voltage and laptop computers clock frequency operation is used when the use of low battery voltage and frequency.
* Do not install through the pins to the motherboard - desktop machine pin and socket take a lot of space. In some notebook computer motherboard, the processor installed directly on the motherboard, do not use sockets. Other motherboards use the Micro-FCBGA (flip chip ball array network), which is used instead of the ball pin. This design saves space, but in some cases also means that the processor can not be removed from the board to replace or upgrade.
* A sleep or slow-running mode - If the computer is idle or processors do not need to run fast, computers and operating systems will complement each other to reduce the CPU speed. Apple G4 processor, the priority will be determined to maximize the data save battery power.
