purchase portable eight-note
as prices continued to decline, many friends have a plan to purchase notebook computers. But how to choose one suitable for my laptop, not every friend are very clear. Let me from the hardware configuration on to laptop purchase should pay attention to several problems, hope to help members in the purchase of notebook computers.

1, enough CPU line

now on the market of mainstream notebook CPU is Intel p-III, and Celeron series, current Mobile P4 is listed, but not much, in addition, AMD and VIA C3 notebook CPU, but rarely use. But now use "grams of paddle-shuttle" power CPU products also on the rise. Laptops, CPU is not faster, the better, if your notebook is used to run popular Office software, PIII and Celeron 800Mhz already has more than enough, excessive pursuit of high frequency lead to high power consumption, high fever and other problems. When we purchase must figure out whether the CPU is the most critical for the Moblie CPU (notebook dedicated CPU), some manufacturers to reduce the manufacturing cost, using heat and power consumption in a laptop desktop CPU with higher Hp Pavilion Dv6700 Battery, despite special treatment, it is still difficult to ensure that stable operation for a long time, power and heating is very ill, do not recommend buying with this class of CPU laptop. When you purchase, you can use the dedicated procedure Intel "Intelprocessor Frequency ID Utility" test your CPU type, and detailed technical parameters.

2, should be appropriate to

TFT display screen size is the current mainstream products, other types of products, such as DSTN basically has been eliminated, the advantage is that the brightness and contrast TFT high reaction speed gateway laptop batteries, Visual angle of the screen, rich colors, TFT has the normal type, black crystal and low temperature polycrystalline silicon TFT, a different type. Purchase we should first determine its size, currently mainly 12.1, 13.3, 14.1, 15 inches. General Home Select 12.1, 13.3 size on it, however important to note that you should support the standard resolution of 1024x768. No special-purpose, not too much excessive pursuit of display. Display of excessive means greater weight, power consumption, and price.

select except when the display size of a laptop, should take a look whether it is appropriate the brightness and contrast of the display, the response time is the normal of the display, display color is bright, and so on. Course should also observe the pixel on the LCD, in general bad point must not exceed three.

3 displayed, not neglect performance

notebook display is also affect the overall performance of key, decided to show performance of main factor is the display chip and memory size, type, and so on.

notebook display chip used in General is at the present stage of ATI RAGE MOBILITY 128, and SAVAGE/MX, using MOBILITY notebook is 7,500 and 8,500 Hp Pavilion Dv1000 Battery, and GO meet with you, their 3D performance better. Of course, mainly to see how to choose the display chip specific uses you buy notebook, if is the General word processing, Internet access, high-performance display chip to higher power consumption instead of sorts.

at present most of the high-end zxcsky32645 products integrated in 16MB of memory, and low-end computer is 4MB or 2MB or even a shared system memory, naturally less performance. Recommended friends to buy try not to select memory below 4MB notebooks and shared system memory, to ensure that a sufficient number of display performance.

4, motherboard chipset is important

notebook integration is very high, its Board type effect on performance is especially important. Of the current mainstream notebook motherboard chipset Intel 815EM, 830MP, 830M, 830MG, SIS 630S, series of the Intel 830 chipset due to support features such as 133MHz FSB and excellent stability of p-�� and compatibility and are widely used in high-end laptops. Intel 815EM chipset CPU, 4xAGP supports the high frequency technology, and built-in I752 display chip, mainly for the Celeron laptop. SIS630S single chip design, integration, SIS300 SIS7018 sound card graphics, SIS900 10/100M network card, this high level of integration of product price is cheaper, is widely used in low-end notebook, but less on the performance and compatibility.

5, hard drives, and memory

and different CPU does not have to pursue high frequency, laptop hard drives and memory size, I think it should be as large as possible. In General hard drive size should be no less than 15GB, and memory should be not less than 128MB; current mainstream laptop hard drive size should be at about 20~40GB, memory not less than 256MB. Also in the purchase of notebook computersWhen should know something about the upgrade and expansion capabilities of a laptop, do you have a spare Bank of memory, the CPU can be upgraded, the maximum supported much of the hard disk, ready for upgrade or extension of computer hardware in the future.

6, volume, weight and light

notebook is welcomed, a very important reason is its portability. Notebook computer out of his suit, presentations, and other uses. So I do not suggest that you buy too much too big laptop. Best choice in 2KG, ultra thin light soft swap is appropriate. Attention

7, battery performance testing

notebook computer battery used nickel-hydrogen battery and lithium battery in two ways. Ni-MH batteries are inexpensive, but there is a memory effect and weight than the lithium batteries in the same capacity in many, and virtually no memory effect of lithium batteries, power and light weight, long has become a notebook computer battery standard. When we buy laptop not only to pay attention to the types of batteries should also note that the battery capacity and the actual use of time, the General capacity of more than 3000 mAh, used preferably in about 3 hours in order to meet the needs of our daily activities in the field. At present, the laptop battery is generally between 3000mAh, there are very few 6000mAh, its higher value, in the same configuration using a longer.

8, other considerations

such as acoustics is good or bad. Cheap cheap notebook sound card are mostly AC\97 soft sound, combined with cheap speakers, sound effects will naturally less. While high-end laptop will use ESS Maestro2E, CMI8738, hard sound card chips, coupled with the natural outstanding 3D stereo speakers effect. Should also consider whether it has wireless networking capabilities, BIOS of the motherboard supports USB devices and other factors
