What should be noted when buying a laptop

What should be noted when buying a Asus laptop? like Asus Eee PC 8G(1G RAM) or Asus Eee PC

Part of ordinary card users This article is not very professional knowledge to understand the user to see, I have the following simple way to tell us The notebook graphics cards. Notebook and desktop graphics card difference is that it can not be replaced, unlike desktop graphics cards can be Arbitrarily removed. Notebook computers belonging to integrate, to replace the little equipment, the purchase must be considered when the notebook To all aspects of performance, not to say CUP strong, hard drive space, enough memory to your notebook's picture on the deal Strong in all areas has a different use, and different grades of graphics cards for what kind of work has superior performance, For the purchase of laptops for a good time to buy their own graphics cards is to the total. How to above were used for graphics This performance? You can see the following table. Simple classification of what kind of graphics cards for doing the work, to buy their own What is the most cost-effective. Business office: office with notebook users of notebook graphics cards on the need for high performance requirements, you can meet Many of these graphics cards, but can not spend money to buy a more powerful graphics cards to use the notebook. You just need a Man Foot office with the laptop, but the use of fever to buy a graphics-class notebook is not it worthwhile? All you need to To buy, such as the use of S3 Savage family and the above-mentioned type of motherboard integrated graphics, more than enough, tired of working time with Listen to music, look at the DVD, game play can cope with. And the use of such cards to the office of the notebook is no problem. Entertainment games: 3D Game notebooks can not play the argument has been broken and now there are a lot of notebooks using the n VIDIA GO series and the ATI Mobility Radeon series of 7500, and this type of graphics performance far beyond the type of integration Graphics, they have unique skills and characteristics. Important to use this type of notebook graphics cards can be a very good run now Popular 3D games, such as: Counter-Strike (Counter-Strike), Quake 3 (QuakeIII-arena), Warcraft Ends 3 (warcarftIII). But also the entertainment world. 3D fever: If you are really demanding 3D, and also go uncertainty often, you can now use A notebook. You can meet the requirements, I am afraid the only nVIDIA's GeForce4 440 GO's ATI and ATI Mobility Radeon 9000, they are a superior performance, and can be comparable to a desktop graphics cards. And And the use of this type of notebook graphics cards are used in Intel's most proud of the Pentium 4 processor, whether you used to play Most 3D games or use of the best 3D software will be able to do most perfect run. Business class of office S3 Savage series, Intel 830MG & Intel 815 motherboard integrated graphics, SIS 650 & 630 motherboard integrated graphics, ALI motherboard integrated graphics This type of graphics cards have in common is not very good 3D effects belonging to the low-end commercial-type aircraft and is used in this notebook only to see the work of learning to play DVD game users will have the best option Game entertainment Geforce2 GO ATI Mobility Radeon 7500 Graphics Since it is a 3D game entertainment, of course, the effect of this kind can not be inferior to the 3D graphics cards for ordinary fans can be said to be the first choice 3D-type fever GeForce4 440 GO GeForce4 420 GO ATI Mobility Radeon 9000 If you need to work on 3DMAX, and other large-scale 3D software for 3D games or your results is very high and do not want to play QUAKEIII any hesitation that your only option is to use this kind of notebook graphics As consumer demand for mobile PCs, notebook computers have long become the first choice for the minds of many people. But how to buy a good laptop? In fact, for those who do not understand the industry, the majority of it is quite at a loss. Below we try to explore several ways to find out what is the purchase of notebook computers what they should do, this is for your reference.

First, the brand notebook: Generally can be divided into the following categories:

1), an international brand. Mainly the United States and Japan brands, including IBM, Toshiba (TOSHIBA), DELL, Compaq (COMPAQ), Hewlett-Packard (HP), and so on. Its brand more outstanding product quality, market share is rather high price, of course, also the most expensive.

2) The Taiwan brand. Include Acer (Acer), Asustek (ASUS), Twinhead, and so on Compower. This type of notebook technology is mature, relatively cheap price, buy a lot of people.

3) domestic brands. There are Lenovo, Founder, and so on here. As the cheap, easy maintenance, more and more users enjoy. Second, to discuss the main components: 1, motherboard: the cornerstone of a strong Integration of notebook computers is very high. Some of the main functions are to focus on the motherboard, the board decided to direct the performance of the machine's performance. Intel's chipset performance and quality is the best, price is the most expensive; In addition, the most common is the SIS and ALI chipsets, low-cost machines are generally used two chips, stability Is very good, but in performance compared to Intel and there is a considerable gap.

2, CPU: healthy heart If strictly from the perspective of design, used in notebook computers on the CPU must be "laptop-specific processors", commonly known as "Mo  bileCPU". If the notebook computer using desktop CPU, will increase the burden on the cooling system of weights and machines. Therefore I do not recommend the purchase of desktop processors using the notebook. So, please purchase definitely the time wanted to make sure it is used in notebook computers dedicated processor. Here to teach you a way to differentiate: WINDOWSXP in the system, in the "My Computer" right-click and select "Properties", the system will be able to appear in the status bar, status bar systems have processors, as long as the laptop is a dedicated CPU , Will have two frequencies in the column processor speed, is a maximum frequency, a frequency now is because of special notebook CPU at that time you can run the actual demand to control the operation of the CPU frequency, so Reduce power consumption, while the desktop CPU frequency is only one of the show.

3, LCD screen: beautiful eyes In the purchase, the LCD screen of the need to pay attention to a few places, one problem Dead, and the other is the reaction time and the third is the level of liquid crystal screen itself. Dead is Chang also said that the LCD screen are bright or dark spots. Dead to avoid necessary to ensure that each tube and TFT liquid crystal devices not bad, in this process is very high on the request. Therefore, the state is less than seven qualified for the following items, it is necessary to test whether there is a Dead-screen liquid crystal display as long as a monochrome image, carefully observe any particular bright spot in it. Furthermore, the reaction time is. Reaction time is the system of receiving instructions input device, to reflect on the time display, that is, whether there is a smear study the phenomenon. The simplest way is to open the test page in the long text, press the down arrow Scroll down to observe on the screen know. Reaction time is as short as possible. In addition LCD screen that is the level of the problem. LCD screen, we can also called TFT display. General in the low-cost notebook computer using the XGA screen, the better it is SXGA, and UXGA targeted at certain sectors of machinery design (such as design, graphics, editing and the like on the resolution demanding the work of) the general home Do not need a computer. However, LCD is the price of notebook computers in the allocation of close to but a great difference.

4. Power adapter and battery life Notebook computer power adapter through ACAdapter (alternating current to direct current variable) and the battery. A variety of power adapters have their own input / output voltage and power ratings, using the process would be best not to pay attention to the different models of notebook computers equipped with the power adapter mix, so as not to burn the machine. In addition, when the purchase should be noted that in a long time to work, how the temperature of the power adapter, if not too normal. However, it can ask in advance to the dealer. At present, notebook batteries are mainly used by the Lion and two Ni MH battery. Lion (lithium) batteries are currently the mainstream for the general intelligent battery with a memory function and light, the use of longer, more expensive prices; Ni MH battery and a heavier weight, and often need to discharge the battery, Relatively inexpensive. Battery life about 2 to 3 hours, the need for a long time to use (for example, frequently engaged in outdoor activities or travel of staff), you can choose to use a longer period of time and battery power setting (Suspend) of the , Second or backup battery.

5. Hard disk capacity The hard drive capacity is increasing. In addition to capacity, we must also consider the thickness of the hard disk, speed, impatient tone, with an average seek time, whether in areas such as power parameters.

6. Expansion of the performance With each passing day in the future, should take full account of the expansion of product performance (for example, memory expansion, parallel port serial, PCMCIA slot, docking port, USB, etc.) and scalability (such as the CPU upgrade, etc.).

7. Design and other equipment The appearance of the machine, color, size, weight, etc. are all factors to be considered. Touch pad or mouse, check equipment and convenience, from the keyboard keys are reasonable, the use of function keys are in working order and how to handle these needs into account. Third, it is worth noting local Good after-sales service is very necessary and important; both from the practical point of view or from an economic point of view, should be suitable as a standard; in the selection of models, they should pay attention to personal preferences, such as product size, weight, the keyboard layout And the touch pad design, screen size, design and so on, as far as possible to meet their personal preferences, but also with the ergonomic and easy to operate. These are some of the purchase of machinery should have some background knowledge. Users can pre-purchase from a variety of media (including newspapers, television, Internet, etc.) and the manufacturers or vendors to obtain relevant information and prices.
