Evaluation criteria

1, CPU, this mainly depends on the frequency and level two cache, the higher the frequency, the level two cache is bigger, faster, the future CPU will have a level three cache, the level Four cache etc., all influence the response speed.

2, the memory, the memory access speed depends on the interface, particle number and storage size ( including memory interface, such as: SDRAM133, DDR233, DDR2-533, DDR3-800 ), in general, the more memory, data processing ability is stronger, faster.

3, motherboard, mainly processing chip, such as: processing capacity of more than i945 chip i965, i945 than i910 chip ability in data processing and stronger, and so on.

4, the hard disk, hard disk in daily use, consider less, but also has some influence, first of all, hard drive speed (: high-speed hard disk and low speed hard disk, hard drive speed is generally used in large server, such as: 10000, 15000; low speed hard disk used in general computer, including notebook computer ), desktop computer with 7200 rpm, notebook computer with 5400 rpm, which mainly considers the power consumption and heat dissipation causes.

Hard drive speed because of different interfaces, different rates, in general, IDE and SATA ( which is often said that the serial port ) interface, the earlier disk is IDE interface, by contrast, access speed is slower than the SATA interface.

Hard disk with the development of the market, the cache rose by the previous 2M to 8M or more, like the CPU, the larger the cache, speed will be faster.

The fourth. Follow the trend is not necessarily wrong, fire performance prominent type usually sell, and feedback the problem, you can have a better understanding of the advantages and disadvantages of the products.

Fifth. Concern for easy to use models, pay attention to elegant details. If you can buy in the store, you must have a good experience it makes you feel ( appearance feeling ) make reference to choose other books is good for you

The six, pay attention to some online evaluation. Reflect the problem many things one-sided (after all, only drawback is often used to reflect ) but you can know this kind of machine common or possible problems, understand the solution of this problem, is of benefit to the maintenance of the machine.

Finally, computer and won't have too big difference, often to find the most cost-effective most popular computer is not necessarily the best. In general for you, but the price you can afford in inside is a good choice. Do not blindly buy expensive ( after all, when a lot of computer performance is really wasting )

Some selected computer methods, have a look.

The configuration of the computer, mainly to see the CPU, graphics card, motherboard, memory, hard drives, monitors, notebook, and then look at its brand on the line. The HP, apple, Panasonic, Toshiba, but customer reputation and quality of hard DELL and HP these two brands; domestic: Acer, Thunis, Tsinghua Tongfang, Shenzhou, Haier, Lenovo, eight hundred million space-time.

In answering questions about notebook purchase issues. Do a simple summary of the hand.

One, buy Computer preferences, preferences are generally two, but well distinguished in buying computer when you first consideration: 1 use: when you choose the relatively wide in the economy, pay more attention to the notebook can meet the requirements of your application, especially the performance of work or game. Then is to choose the appropriate price in the performance of computer. 2 price: when you have identified the economic budget, and the Dell XPS M1330 PA-21 Adapter

specific use directions on the unknown when the computer (for example, just know what to play games, have a look the movie ) then in the price line for upgrading performance dominant potential computer.

Second: product upgrade issues often not easy to upgrade. Many related parts replacement is not easy ( card and the like ) and Intel seems to pay attention to this aspect, in the same series is given in different grades of isomorphism frame selection ( I3, i5, i7 etc.) in the same series of upgrades to easier.

Third. Pay attention to the brand and price characteristics. Different brands have different emphasis. Such as the recent Lenovo products focused on the popularity and popularization. While the Dell is customer service and quality of the old factory. China, went high configuration line. There will be a skill in the selection, such as the budget is not much attention to brand China. The quality requirements of high, can choose the Dell series. Often in the brand had some configuration similar price is almost as we called competitive products. Often this kind of product is the manufacturer attach great importance to the products, cost-effective in general will be relatively high, and better use of popular group, problem feedback. Is worth paying more attention to.

even the world of Warcraft also need 128M memory can be, even the core requirements are not. But the United States of America single is not the same, as long as the general 512M of memory is enough, and some extraordinary transformation requires 700+M memory ( had to buy 1G memory .).

4 ) hard disk. The hard disk directly determines how much can you put on your computer, as far as possible to buy big, even buy small does not matter, also can change, is now floods in Thailand, a lot of hard drives are washed away by water, so the price, if you want to change the hard words, it now.

5 ) operating system. In fact, this is not a big matter, they can be installed, it is important that is most important to give full play to the hardware capabilities. If a smoothly and the loss of performance is greatly worth. The new hardware is always the latest operating system design.

2 ) performance. As computer performance, CPU is very important, it directly affects the working efficiency of the computer, such as the boot speed, win7 quad-core boot speed of 25 seconds, and the duo is 40 seconds, there are more difference required two minutes. So choosing CPU, the higher the frequency, the higher the efficiency, the core technology of CPU is high, efficiency is high, and the latter also preferred. Second is the memory, to ensure efficiency, memory is certainly not too bad. XP 512M if possible can run very well, but the win7 and Vista 1.5G, 64 plus 0.5G, or use the experience will be greatly reduced.
3 ) video. Here is not only the media file, and the video game. This card will occupy more important position. Now the card has three giant, NVIDIA, ATI, INTEL, the former two are the main. NVIDIA is good at the game rendering, while the ATI is to pay attention to the projection and production of media files. Graphics should first see production process, while the core is the same, but different brands, the effect will be different. NVIDIA brands for cable and GALAXY, ATI and Dataland in a sapphire. Then look at the core and interface, usually first look at the core, but in the algebra of similar circumstances, priority watch width. Width of general 128bit is game entry level. Then the memory, the general online games of cards required is small

In general, the host in the various parts of the full-load power add up, and the maximum value is lower than the rated power supply, power and power to the more room, so that it can. In addition, the display is independent power supply, has nothing to do with the host power supply, so it don't count display power consumption time.

A little more professional look at 12V output power supply adequacy. 12V is the power supply to the CPU and graphics card, which is the two largest parts in the host power consumption, which accounted for most of the host load power consumption, so as long as the 12V power output power can drive CPU and graphics card is almost. Because the 12V power output power is lower than the rated power, so only the rated power is not insurance, which is why I said above rated power to some reason to set aside.

12V output power is relatively good, formal power will mark the 12V maximum current in the power plate, 12V multiplied by the maximum current value 12V output power is the power of the. For a 12V power supply ( the most common is the dual 12V ), must be calculated by manufacturers, given 12V combined with maximum output current to if not, there is no way.
Computer power now popular through the 80plus certification, the certification through the formal power, conversion efficiency is high, can give you save a lot of electricity, and support for 100-240V full voltage, can deal with the voltage instability problem. If the budget is not very nervous, try to choose through the 80plus certification of products. Hello computer does not like you want to change 1 configuration can accelerate the speed of the main overall configuration you like 1 people walked on 2 legs and 2 legs to general long ( at least about ) 1 long 1 short or long leg length is not going fast machine is the same network. See you the bandwidth is the number of 1M and 2M of course not the same computer is receiving relationship is not large unless you are a virus or other software

Tiny spots of bright light will influence the user experience, caused by the user's visual interference, may be misleading heavy users of graphics and image error of judgment, and even cause irreparable economic loss to the customer.

Aiming at the problem of consumer, ASUS notebook computer manufacturers in 2003 March 1 to sell the full range of notebook computer LCD screens provide no guarantee of bright spots. Where in March 1 in the purchase of ASUS notebook computer user, if it is found that the notebook screen window, can hold purchase invoices to the purchase within 30 days from the date of the ASUS customer service line ( 800-8206655 ) was the replacement of non-bright LCD screen service. This service will guarantee the purchase of notebook computer users can enjoy the best display quality

Based on the investigation of the consumer, we see that the notebook computer users on the LCD display quality attention is that they rarely common needs, directly caused decline in display quality is bright screen, the user is very hate highlights on the LCD screen and can not tolerate people who have occupied 87.41% of the total sample. The quality of visual effects has become a lot of notebook computer users evaluate an important indicator of quality. Highlight the issue of the notebook has become a prominent issue for more on consumer notebook. Dell Latitude D520 AC Adapter

Notebook computer filled with personality has gradually entered public life, as a high degree of technology integration products, in the purchase process, there will be a how to choose, choose problem. Now we buy notebooks have focused on the frequency, distribution. In addition to these performance indicators, and other details of the notebook is more worthy of our attention.

First is the visual experience. In fact, whether the frequency of notebook computer or configuration or notebook computer, all belong to the internal parts, they are mainly performance of notebook computer, only one application of the concept, as long as the user selects one to meet the needs of their own configuration can be, and we usually the largest man-machine dialogue LCD showed a factor the screen is not to be ignored. Before the user or remain in the color images show the effects of the pursuit, now elevated to the height of the display quality. Dell Inspiron e1705 ac adapter

Proposal to buy Lenovo notebook, I bought three, feel good

Personal feeling to buy computer don't consider price, cost-effective high performance computer is only temporary, followed by a phase of the problem came out, the most common is the hard disk bad or notebook cooling do not, this will make you very entanglements. It is best to consider the life of the hardware, the hardware of the combustion, the cooling machine.Dell Laptop AC Adapters
