Basic knowledge of laptops
Mobile Processor:
Notebook processor is different from desktop processors, which take into account power consumption, therefore the introduction of more advanced manufacturing processes and technologies to achieve as much as possible, while reducing power consumption to achieve high performance. And different mobile processors have their own energy-saving technologies (power management) can work with the processor adjusts the processor frequency or voltage reducing power consumption to DELL INSPIRON 2600 SERIES battery. The current mainstream mobile processors - Pentium M, Celeron M, Pentium 4-M, Athlon XP-M and Transmeta Crusoe, and as Pentium III-M, K6-3, C3 and other mobile processors are breathing has been long products, users do not need to consider when choosing a.
Pentium M processor with low power consumption, high-performance features, is Intel completely designed and developed for laptops, so that a qualitative leap in notebook, but as a new product, so a notebook with this processor are high-end products, prices are more expensive, this is a more versatile product and, therefore, positioning of the notebook will see its shadow, ultra-light notebook so that it substantially improves performance.
Celeron M processor is the Pentium M processor, a simplified version, and the Pentium M uses the same core, targeted at the low end. Therefore, the listing Celeron M, Pentium M, so a lot of the original version of the high-end notebook computers also have a corresponding low-cost model, the same model with Celeron M processor, the product than the Pentium M's products generally around 2,000 yuan cheaper, and its performance also fully able to meet the needs of general users, so the students, families, business users demanding performance requirements can not be considered Celeron M models.
Pentium 4-M processor is a desktop processor by the improvement from the mobile processors, due to its low price, performance is not bad, it has also its market position, its biggest drawback is that power consumption than high. However, due to the high frequency, and the latest version also supports Hyper-Threading technology, the multimedia processing performance of its office there, so it is still widely used in multimedia notebook, desktop, notebook alternative, if You totally have to buy a notebook for use in the home computer, with Pentium 4-M product is a good choice, after all, this part of the current models have a high cost.
AMD Athlon XP-M is introduced for a new Pentium M mobile processor, its performance excellent, cheap, relatively speaking, but still a good heat and power consumption and the Pentium M can not compete, but due to low price performance is not bad, so many more than in the low end of the 14-inch models were used. Many students, inexpensive volume is less than the Athlon XP-M notebook is a good choice.
Transmeta's Crusoe is an ultra-low-power mobile processors, like using a software simulation of hardware, processing algorithms, thus greatly reducing the number of transistors for low power consumption control, but the corresponding performance is also not high , but it has many mini-notebook computers are used, this type of notebook 5.6-inch, 8.9 inch, it is not asking for the performance of products, ultra-portable is its pursuit, he also has its part of the market . In addition, the Transmeta Efficeon processor will soon release the latest, and we look forward to this ultra-low-power mobile processors, improvements in performance.
Chipset:
Motherboard chipset and the laptop is also very important components, the performance of both the performance or the overall power consumption of the control, and chip set are related. Overall performance in the notebook computer, the best non-Intel DELL LATITUDE CPT S SERIES battery, none other than moving, whether it is memory, disk performance, or power management are the best, the other competitors in this field also can not compete, which is Intel in the notebook one of the reasons the field ahead. In addition, laptop chipset in common are SiS, Ali, and Ati North Bridge + Ali South Bridge, the other also VIA, but generally appear in notebooks using AMD processors, these chips while there in the market, But in reality very few products in the market share, often appeared in some low-cost notebooks.
Note of certain ultra-low cost notebook chipset, processor and memory are used the desktop machine parts, although this low cost, the price is cheaper, but overall stability is questionable, and interior design Yiji heat aspects of concern, and there is no expansion slot notebook is very important - PC card slot, in the strict sense can not be counted as a notebook computer, notebook computer users to buy cheap to pay attention to this.
Memory:
Notebook and desktop memory, memory is completely different specifications than the average price of desktop memory, much more expensive, but the small size is conducive to the internal notebook design. The current notebook memory also commonly used DDRAM, SDRAM basic also outdated, and only older computers will be used to upgrade, so we buy laptop computers are generally for the DDRAM memory specifications, one for the more common SO DIMM Notebook memory; way for the Micro-Dimm memory. Micro-Dimm memory normally used in ultra-thin notebooks, than the standard SO DIMM memory is smaller than half the price is also very expensive. Notebook memory for speed is not high, it seeks a stable operation, it now supports the highest standard laptop notebook memory only to DDR333, but the speed limit because notebook hard drives, notebook computers is a great reliance on the memory and proper configuration of high capacity memory of the notebook's overall speed upgrade will obviously help.
Hard Disk:
Laptop hard drive can be said that the development of the slowest laptop computer parts, has long been a qualitative leap in speed are not currently widely adopted specifications or 4200 switch, 5400 switch to the beginning of the notebook models in a number of high-end products appear 7200 notebook hard drive though has been released, but due to taking into account the maturity of the technology, currently very little notebook. At present, the size of a notebook hard drive is divided into two 2.5-inch and 1.8 inch, 2.5-inch notebook hard drives have reached the maximum capacity of 80GB, is often widely used in notebook computers; and 1.8-inch notebook hard drive capacities up to 40GB, rotational speed only 4200 turn up, by some extreme light notebooks Dell Inspiron 9400 battery (for example: TOSHIBA R100, SONY X505 product of extreme light), expensive, difficult to upgrade too.
Mobile Display chip:
With the increasing performance of notebook computers, gaming has also become an entertainment notebook. Mobile ATi cards in the field also remains the world, although the rising star of nVidia catch up, but the overall power consumption and performance to be slightly behind the ATi. The current most powerful mobile graphics card comes as ATI Mobility Radeon 9700 and nVidia Geforce FX Go5650, although the performance of two powerful graphics card, but power consumption is not small, generally used in mobile multimedia-centric notebook or desktop computer instead of product-based computer, users for playing games of course, is the best option. There are also some other independent also have strong 3D graphics performance, Mobility Radeon 9600, Mobility Radeon 9000, Geforce FX Go5200, Geforce 4 Go440 mobile graphics chips are good, the performance of arrangement: Mobility Radeon 9600> Geforce Go5200 > Mobility Radeon 9000> Geforce Go440> Mobility Radeon, its power and performance is generally inversely proportional to, so they appear in different models of orientation.
In addition, the notebooks show that there is an area to be reckoned with, they are integrated graphics, they are the lowest power consumption, but also a good 2D display, and therefore business notebook, thin and light notebooks in general when, or even move the display area The absolute main. Current mainstream integrated graphics chips sort of performance chipset: Intel 855GME Chipset> ATI IGP7000 Series Integrated Chipset> Intel 855GM Chipset> ATI IGP300 Series Integrated Chipset> Intel 852MG chipset> SIS650M> Intel 830MG chipset. Intel's 855GME chipset latest integrated graphics chip, performance is equivalent to the level of ATI Mobility Radeon 7500, is the most outstanding integrated graphics chip chipset. Moreover, you should video memory, integrated graphics chips are the main memory as video memory through shared work in the use of memory to consider when setting the size, too small to affect the display performance, too much is consumed leading to the main memory through main memory small impact overall performance.
Network equipment:
Laptop notebook computer network equipment has become one of the ultimate configuration, Centrino is to vigorously promote its "unlimited wireless" (wireless LAN standard is), but a smash hit, now comes standard with the V92 laptop modem and 10 / 100M adaptive Ethernet card, which is the minimum requirement for network equipment notebook standards, the user must pay attention to the time of purchase the two facilities are complete, or future use might bring a lot of inconvenience. In addition, with the popularity of Centrino, wireless LAN standard has become a characteristic of the notebook, now most of the high-end notebook computers equipped with wireless cards, giving users a great deal of convenience, with the wireless network laying, many public places are covered with wireless LAN, which is a notebook with a wireless card tremendous convenience, of course, wireless LAN standard machine will bring the price to upgrade, but for the HP pavilion zd8000 battery of future upgrades, standard wireless network card or a more cost-effective.
Display:
Notebook computer display can be one of the most important parts of the display size directly affects the size of laptop sizes, the current notebook type can be divided into: 8.9-inch mini-notebook, ultra-thin 10.6-inch notebook , 12.1-inch thin and light notebook PCs, 14.1-inch notebook full size, 15-inch and 17-inch desktop alternative notebook computers. Therefore, the screen size is the user choose an important factor in the notebook to see what kind of laptop you need. The display or notebook computer consumes large, it also determines the power consumption of notebook usage time, and it directly affects picture quality notebook user's feelings, so a good buy laptop display is user when to watch their step.
Notebook purchase points:
In fact, many laptops to buy on impulse when a friend is rushed to go buy, before buying and do not analyze their own needs, not to fully understand the various features on the notebook computer anxious to start, leading to feel the future purchase of products is not as good in their own good, never regretted the decision under.
Rational purchase of notebook computers is to be done before a full analysis, both for their own needs or characteristics of the product to be a clear understanding of, and many users to buy when they do not do this, but listen to advertising or other people's side of the story , one-sided pursuit of models of weight, appearance, brand, etc. Finally, do not buy products for their own, and made trouble unbearable.
The notebook computer products and everything else, are not perfect, but each user's needs are different, but each laptop position, function is not the same, only fully understand their product needs and product characteristics, the election targeted products APPLE M7318 Battery be purchased with money to buy the most reasonable best suited to their machines.
Ask yourself in the end do not need notebook
First, ask yourself what do you want a laptop? If you're trying to show off, it still advise you to immediately scrap the whole idea, notebook computer products updates out too fast, maybe you bought your laptop on the yuan has been reduced after six months out of the object, that is what you will You pay for your last million regret the expense.
If you are not completely familiar with computers, but only used at home, choose the laptop is acceptable, but you need to consider a laptop half the price you can buy a superior performance of the various aspects of the desktop, but also more in future upgrades convenient, so we think you should be the preferred desktop.
What kind of person for purchase of notebook computer? Of course, if your notebook computer work, study and life convenient and enjoyable, then you can not hesitate to select him. For example: frequent business travelers, college students, programmers, and the family's second computer.
Understand their own needs
You in the end to a what kind of notebook? Mainly used for what it does? You only find out these two issues, you will not buy products aimless, confused. If you are a business person, often in the road, then a Wending lightweight business notebook will be your best choice; if you are a student, you may pay more attention to price, but fashion style is that each by young people favorite, so you can choose some low-end multimedia functions for a strong notebook, the performance of all aspects of these books are good, looks are more fashionable, but because students do not need to carry the laptop, so weight may require less harsh, so prices have more choices; If you choose is an office or home with a notebook, with good comfort and overall high performance desktop alternative notebook is your good choice. Of course, everyone's needs are complex and diverse, ultra-thin notebook, emphasizing multimedia notebook audio-visual features are introduced for different users, as long as the user to seriously consider before purchasing this issue, I believe you will have an approximately direction, and then again in the selected areas of specific characteristics about each product, the best options for their products would not be tough.
Clear their own budget
Laptop prices vary widely, even if the same position, configured essentially the same product, different prices for the brand will have poles other phenomena, therefore, choose to do their budget before notebook is also very important, and do Do not amend the budget after.
And this budget, the best two prices, one is your ideal price, you would like a (can) afford the highest price. When the actual purchase, first used at good prices, and only really found the right model, but its more expensive, it will consider the highest price, Asus EEE PC Battery in any case not exceed their maximum price, and not to rely on the recommendation of sales staff and the induction of the open standards, so the final product you buy may be your burden, as the function does not need to pay a high price.
And in determining the model after the purchase, preferably as much as possible from various sources about the price of the product market to determine a more realistic price and then ask where to buy the business, ask a few will not lose out, in the end most is a bargain, the actual transaction price can often lower prices than the business 5 to 10%, that depends on your capacity for bargaining. If the price satisfaction can be shot, if the price is not satisfied, do not rush shots, after all, the price of notebook computers always drop, there is always more than a few times a surprise.
Summary:
Notebook computer is a wide range of products, so users must be clear before buying their purchase intention, adhere to the principle of good enough, do not blindly pursue the latest technology, the most fashionable style, the most robust performance, and not brand awareness too, a reasonable analysis, rational choice, so that will make their own choices to a satisfactory product.
In addition, the domestic notebook market is not mature, notebook computer sales service is a headache. Therefore, before buying you should pay attention to this problem and treat it as an important factor in buying the machine, choose a good brand reputation, fill out a clear time of purchase warranty certificate, a good warranty to determine the time, as much as possible for the longest warranty period, so that users can use the notebook from the peace of mind
