　　How to buy laptops
　　Since many people ask me how to buy a digital camera, recently many of my friends started asking me to buy a notebook computer (hereinafter referred to as notebook) something that actually I am not an expert friends, the time is not long with the best Best Laptops, tentatively summarize some of their own experience into 11 points to share with you.
　　1, the difference on the laptop CPU
　　Buy laptop, the first and most need to know the CPU, the current common notebook CPU from low to high is divided into the following categories:
　　? Intel Pentium Dual Core Series: the Pentium Dual Core T2xxx series, 32-bit CPU, high cost, but for the general Internet, word processing people, more than adequate.
　　? Intel Core 2 Duo T5 Series: the Core 2 Duo T5xxx series, is 64-bit CPU, cache higher than the previous series, with frequency, the more powerful.
　　? Intel Core 2 Duo T7 series: the Core 2 Duo T7xxx series, compared with the previous series, running a complex program, there will be advantages.
　　? Intel Core 2 Duo T8/T9 series: the Core 2 Duo T8xxx or T9xxx series, using 45nm technology, higher performance, smaller and more energy-efficient heating.
　　Before the dual-core series, as well as Celeron M series, Pentium M and AMD series, which followed the Celeron M and AMD notebook choosing the less, I do not consider them. There are still low-cost notebook with Celeron M and Pentium M series CPU, the former still barely make browsing the web, may open a few pages or pconline Taobao page is very painful, do not take into account. If, for funding, the Pentium M series has been able to meet most of the Internet, word processing requirements, but that is out of product, if it is to buy new, or have dual-core or more series. As for what specific version of the dual -core, depends on your specific needs may be, and continue to look down.
　　2, XP or Vista
　　What operating system is installed to another depends on factors you. XP 32-bit operating system, Vista 64-bit operating system. For most people, you can not feel the difference between them, but Vista will consume more system resources, that's for sure. So, if it is for the principle of giving priority to efficiency, should choose XP. If you select XP, then the CPU T2x actually capable of performing most of the work has, on more than T5, the number is a bit wasteful. Of course, the same XP system, a grade lower than a CPU or grade run faster. If Italian is Vista, at least to choose T5 series, otherwise it will be very painful.
　　3,1 G or 2G
　　Said here is that memory, if the general office or home, 1G can be, if it is running Vista, or have to run a large program, added to the 2G right now is still very cheap laptop memory.
　　4, or the set alone was significantly
　　This is good solution, depending on whether you play games, play games, then selection alone was not playing on the set was. You may set was more concerned about is whether to meet the needs. The main set was two points GMA950 and X3100 series, which is relatively new, some strong performance. GMA950 is very reluctant to see high definition movies, and will account for a large CPU resources, which could lead to increased heat. If the Pentium M series, with the GMA950 graphics, some systems also need to close the program, barely able to ensure smooth playback. The X3100 series, watch high-definition film is no problem with dual-core CPU is more than enough. As for playing games, GMA950 basically does not consider, X3100 World of Warcraft, the lowest quality but also to have 25 or more, is not too bad, but the other, the new game, it basically is not considered.
　　5, screen size
　　This weight is associated with the notebook, under normal circumstances, the smaller screen, lighter weight. If it is 12 inches, and the current general in 1.8KG below; if 13-inch, usually in the following 2KG; if it is 14-inch, generally 2.4KG below. If the notebook does not require frequent moves, and you do not go carrying, such as driving the car, it is still selected in the 14-inch notebook it. After all, the screen bigger, closer to the desktop, Ye Hao eyes a little. If it is 12 inches, suitable for carrying around on the go. 13 inch is relatively modest. I belong to people who walk around carrying a laptop, so I chose 12 inches. As less than 12 inches, I think too small, with up tired. Greater than 14-inch ... ... than to buy the desktop, not the person that weight back.
　　6, widescreen or normal screen
　　Currently, the new laptop out, most widescreen. Widescreen (16:9) to facilitate the movies, the normal screen (4:3) to facilitate office (especially the brothers developed to do programming). Personally like the normal screen, a number of practical. Watching movies is better to see the desktop on the big screen, 22-inch called cool. Moreover, some people buy widescreen, is similar to using Vista's sidebar. I said, ah, the sidebar stuff, and expensive resources, and distract your attention, or do not use as well.
　　7, mirror or matte surface
　　Mirror feels more beautiful, a lot of people like the mirror. However, reflective mirror is easy, if long-term fixed in place and there is no reflective light source using a laptop, consider the mirror. If business use, laptop everywhere need to move, or choose a good face scrub, or you will be very crazy. In addition, the matte surface with the advantage that the screen's viewing angle is narrow, the next person is not easy to see what you are doing, have some privacy. Choose matte or glossy surface, it depends on your needs.
　　8, not to drive
　　If you choose a 12 inch or less laptops, the need may be faced with a choice of optical drive. I chose not to, because unless it is to reinstall the system, in fact, the current drive usage has been low, Han can not download it?
　　9, heat and noise
　　13 inch or less in the choice of laptop, notebook cooling to seriously consider the issue, because the laptop in a highly integrated environment, smaller machines, the greater the heat dissipation more difficult. If you select a good cooling machine, hand on the notebook above, not to mention the burning, even if the temperature was also very uncomfortable. As for noise, with the fan, generally laptop fans are with the temperature, that is, the higher the temperature, the fan turn faster, the noise will be greater. Notebook in a large program to run a race under, test to see if you can accept.
　　10, other details
　　Other details to consider such as: vents, if you are a right hand mouse, do not consider the outlet on the right side of the notebook. USB distribution, as much as possible about the choice of the three sides after the laptop has a USB interface, and the interface as much as possible instead of lining up. Keyboard is comfortable, is used to the Fn key with the CTRL key position (some laptops this is the location of two key exchange, such as IBM's and HP's not the same). Battery, if used often to go out, the battery is one of your primary consideration, some notebook will be an optional add-cell battery, while Sony is in flight capacity by doing the best.
　　Basically, the detail is to consider these. Taken together, up to you to buy the laptop to be doing. If it is for the general Internet, word processing, on the choice of T2 Series CPU, with 1G of memory, integrated graphics, the screen size depends on your preferences. If the business model, you need to walk around carrying a laptop, you choose 12 or 13 inch. If the manual is good, or not around the back of the laptop, choose 14-inch. Need to play the game, you have to buy the single display, while the T5 series CPU with significant independence has been able to play most games, then high-end, you still buy a desktop bar.
　　In addition, there is a very important, is the brand of choice. Support domestic products, with the Divine, the price is cheap, but you may want to buy a laptop signs affixed to cover; pursuit of cost, you can choose Dell, but Dell's making my work is to be commended; fashion, choose Sony, and the performance is superior, but make sure there is enough pocket money; pursuit of light, you can see the Fujitsu, but expensive, Toshiba is also the same situation. Neutral point, you can choose Samsung, but I do not like his right outlet. Business type, you can choose HP to design the atmosphere, and very practical. There pursuit of high quality, select Lenovo Thinkpad, although it is not IBM's brand, but the Thinkpad T series and X series is really a classic business machine, the kind of quality, the kind of workmanship is really addictive, And vanity also can be greatly satisfied, so I am using is X61. If the pursuit of Petty, to attract the eye, to buy Apple's notebook, said the latest MBA can be a thin kitchen knife knives to injure, but the old heavy one level than other computers, very unhappy.
　　Finally, Section 11: mainstream, parallel or Used:
　　? licensed: refers to the mainland to buy are genuine, have a warranty.
　　? parallel: refers to the goods is outside the Mainland, Hong Kong is a common line, Singapore line, etc., the price will be cheaper part of it. Trouble is the warranty, to send out. If you choose to own a good quality notebook, for example, ThinkPad, failure rates are low, general computer problems, you are often used improperly. And commitment on behalf of the repair business generally, you can rest assured that purchase.
　　? Second-hand: do not explain. Proposed to select some good quality personal brand, such as ThinkPad, HP, Sony, even if used, can then Shanghao a long time, these machines are worth second-hand priority. Among the most commonly used in the ThinkPad's, because the quality is really good. And Sony's hand is not common, people have quickly grabbed. Basically, the second-hand Pentium M series, and T2 series of machines, for most people, has more than enough, and low cost, is worthy of priority.
　　Of course, parallel imports or to buy second-hand, is more important is to choose a reliable business. This regard, I have some experience, but to avoid any advertising too, not here publicly.
