As prices continue to fall, many friends have had the intention to buy a laptop. But how to choose one suited to their laptop, and not every friend is very clear. The following hardware configuration I have to talk about buying laptop should pay attention to several questions, hoping to tell you, before purchasing any help laptop. Sony VGP-BPS2 Sony VGP-BPS2A
1, the CPU is good enough OK
Now available in consumer notebooks processor market is mainly used in the Core series of Intel, the latest Centrino platform has four available, but many, and more mobile AMD CPU, but the request was not more. But he now uses the “G-LU Soe,” products with low CPU consumption also increased. Notebook Case, CPU is not the sooner the better, if your laptop is used as the common software Typical Office, 1.2Ghz and above CPU is more than sufficient, and making excessive high frequency, power-hungry, but to bring the high heat and so on. We choose the most critical is that we need to know Moblie CPU if the CPU (notebook processor specific), there are vendors to reduce manufacturing costs, on laptops used high heat and the power of desktop processor, although after special treatment, it is still difficult to ensure a long and stable, but also a very formidable power consumption and heat is not recommended to buy a laptop with this processor. When you buy, you can use the dedicated Intel “Intelprocessor Frequency Utility ID “to test the processor type and detailed technical parameters. Sony VGP-BPS2B Sony VGP-BPS2C
2, the screen size must be properly
TFT as current ordinary income, other types of products such as basic DSTN and others have been eliminated, the advantage is the TFT high brightness and contrast, the response speed of display, viewing angle, the such rich colors, TFT is also frequent, low-temperature polysilicon, Super Black Crystal various types of TFT. When you buy your first, we determine its size, at present mainly 12.1,13.3,14.1,15 few inches and so on. Choose the size of the typical house can be 12.1,14.1, but it should be noted that the standard should support a resolution of 1024×768. No particular purpose then does not continue too. Too much screen means more weight, power consumption and price.
In the selection screen when the laptop to share the size, should pay attention to watch the screen brightness and contrast of the ability of response time display is normal, indicating if colors bright and so on. Of course, should also observe the situation of dead pixels on the LCD, usually not more than 3 dead pixels. Sony VGP-BPS8 Sony VGP-BPS8A
3, the display performance can not be ignored
The display performance of laptop computers is also essential to affect the overall performance and decided to present the results of the main factors is the use of the display chip and memory size, type and so on.
At this stage, used in laptops, graphics chips are generally used ATI MOBILITY 7500.8500 and GF4 GO graphics and NVIDIA 8400M GS and so on, their 3D performance even more remarkable. Of course, the selection of graphics chips mainly depends on the specific use of mood laptop you buy, except that the general text processing, Internet and so on, then the high-performance graphics chips made in a higher power, but bad.
At present the finished product the most integrated high around 64 MB of memory, while low-end PCs are mostly 16 MB or 32 MB of shared system memory and even the performance of natural ventilation. The proposed purchase to make friends, do not choose less than 32 MB of video memory and a shared main memory, laptop computers, to ensure proper display performance. Sony VGP-BPL8 Sony VGP-BPL8A
4 chipset motherboard is very important
Integration of laptops is very high, the type of advice on the impact of overall performance are particularly important. This step, the ordinary mobile motherboard with an Intel chipset used in the 945EM, 965PM, etc., in which the Intel 830 series chipset supports 133MHz FSB and other characteristics and excellent stability and compatibility have been widely used in the High-end laptops P Ⅲ. Intel 815EM chipset to support high-frequency-doubling of the CPU, 4 x AGP technology and integrated in the i752 graphics chip, mainly used for laptop Celeron. SiS630S design into a single chip, sound SIS7018 integration, graphics SiS300, SiS900 10/100M Ethernet, the price of highly integrated products were relatively cheap in low-end laptops are widely used, but in terms of performance and compatibility are actually some worse.
5, hard disk and memory as large Sony VGP-BPS9 Sony VGP-BPS9/B
And the CPU is not the continuation of the high frequency, laptop hard drive and memory size, I think it would be great. In general, the capacity of hard disk should not be less than 15GB, but the memory must not be less than 128 MB, the capacity current mainstream notebook hard drive would be 120 ~ 240 GB or more memory n is not less than 1G. Also at a time when buying a laptop laptop should consider the modernization and capacity expansion, where extra memory slots, CPU can upgrade hard drives and all greater support for future improvements or expansion of computer hardware do a good job preparing.
6, the volume must be light
The reason why laptops are welcome, a very important reason for it is in its portability. Notebook computer multi-away travel, presentations and so on when to use them. Therefore, I do not recommend you buy a laptop too. The best choice 2KG below Guangruanhuhuan of ultra-thin more appropriate.
7, the performance of the battery of tests of attention Sony VGP-BPS9/S Sony VGP-BPS9A
Batteries for laptops are mainly used in nickel-metal hydride batteries and lithium twofold. The Ni-MH batteries are cheap, but there is memory effect, but also in the same capacity under the weight ratio of a large number of lithium batteries, but lithium batteries are not normally of memory effect, and light weight, power for a long period has become a standard notebook computer batteries. When you buy a laptop, we must not only focus on the types of batteries, but should also pay attention to the battery capacity and the actual use of time, generally more than 3000 mAh of capacity in use time, preferably 3 hours to meet our daily outdoor. Currently, the laptop battery is 3000mAh to 4500mAh generally, there is very little 6000mAh, and its highest value in the same configuration using the longest.
8, other factors to consider
For example it’s good or bad. Economics cheap laptops are mainly used in the sound card AC \ 97 sound card soft, with speakers cheap, sound effects are naturally some differences. While high-end laptops will be used Maestro2E ESS, the CMI8738 sound chip and other hardware, and stereo speakers with 3D effects of a natural product. In addition, should also consider whether to feature a wireless network, the BIOS or not to support the USB device at startup and so on. Sony VGP-BPS9A/B Sony VGP-BPS10
