Basic knowledge of laptops
Mobile Processor:
Notebook processor is different from desktop processors to take into account the power to reach so the introduction of advanced technologies and manufacturing processes as much as possible, while reducing power consumption in order to achieve high performance. And various mobile processors have their own energy-saving technologies (power management) can work with the processor adjusts the processor frequency or voltage reduction in power consumption on 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 a Pentium III-M, K6-3, C3 and other mobile processors are breathing long products, users need to not on the selection a.
Pentium M processor with low power consumption, offering high performance, is designed in full and Intel developed for laptops, so that a qualitative leap in notebooks, but as a new product, a notebook processor This is high-end products, Prices are more expensive, it is a versatile product, and thus the positioning of the notebook has its shadow, ultra-light notebook seen, so it does not improve performance significantly.
Celeron M processor is the Pentium M processor, a simplified version, and the Pentium M uses the same core, targeted at the lower end. Therefore, the list Celeron M, Pentium M, so much of the original version of the high-end notebook computer also has a corresponding low-cost model, the same model with Celeron M processor, the product as the Pentium M Products usually around 2,000 yuan cheaper, and its performance are also fully able to meet the needs of users overall, so that the students, families, business users demanding performance requirements can not be as Celeron M model.
Pentium 4-M processor is a desktop processor through the improvement of mobile processors, due to its low price, performance is not bad, it is also his position in the market, the biggest drawback is that the energy consumption to be high. But because of the high frequency, and the latest version also supports Hyper-Threading technology, the multimedia processing is carrying out its tasks, it is still widely used for multimedia notebook, desktop, notebook alternative, if you must necessarily buy a notebook for use in the home computer with a Pentium 4-M product is a good choice, after all, this part of the current model at a high cost.
AMD Athlon XP-M is a new Pentium-M mobile processor presented, excellent his performance, inexpensive, relatively speaking, to compete but still a good heat and electricity and the Pentium M, but is due to low price performance is not bad is used so much more than the lower end of the 14-inch model. Many students, is cost of less than Athlon XP-M notebook is a good choice.
Transmeta Crusoe’s is an ultra-low-power mobile processors, such as using a software simulation of hardware, processing algorithms, greatly reducing the number of transistors for low power consumption control, but the same performance is also not high, but it has many mini-notebook computer is used, this type of notebook-5. 6-inch, 8 9 inches, which is not the product performance, ultra-portable, it follows that he also has a part of the market. In addition, Efficeon will soon have the latest version, and we look forward to this very low-power mobile processors, improvements in performance.
Chipset:
Motherboard chipset and the laptop is also very important components to control the performance of both the overall performance or power consumption and chip-sets relevant. The overall performance notebook computers, the best non-Intel Dell Latitude CPT S-Series Battery, nothing but motion, if it is memory, hard drive performance, and power management is the best, the other competitors in the field can not compete Intel’s notebook from one of the reasons is the field before. In addition, the laptop chipset in common SIS, Ali, Ali and Ati Northbridge + Southbridge, seem to others but also by, but usually in notebooks with AMD processors, the chips, while the market there, but in Indeed, very few products on the market share, often appeared in several low-cost notebooks.
Remember a couple of ultra-low-cost notebook chipset, processor and memory components are used in desktop machines, although these low costs, prices are cheaper, but the overall stability is questionable, and interior design aspects of Yiji Thermal concern, and there is no expansion slot notebook is very important – PC card slot, will not strictly be counted as a notebook computer, notebook users to buy a low-cost care.
Memory:
Notebook and desktop memory, memory is very different from the specifications of the average price of desktop memory, more expensive, but the small size is conducive to the interior design of the notebook. The latest notebook memory often used DDRAM, SDRAM Basic also outdated, and only older computers will be used to upgrade, so we buy laptops in the rule for details DDRAM memory, one for Shared memory SO DIMM Notebook are: systems for Micro-DIMM memory. Micro-DIMM memory commonly used in ultra-thin notebooks, instead of the standard SO-DIMM memory is less than half the price is too expensive. Notebook memory for speed is not high, it is a stable company is looking for, it now supports the highest standard notebook memory laptop only DDR333, but the speed limit for the hard drive notebook, notebook computer is a great confidence in the correct configuration of the memory and high memory capacity of the notebook overall speed upgrade will help, of course.
Hard Disk:
Laptop hard drives can say that the development of the slowest parts of laptop computers have long been a qualitative leap in the speed was currently not generally change specifications or 4200, adopted 5400 switch to a notebook models run number of high- end products from 7200 notebook hard drive is released, but by taking into account the maturity of the technology that is currently too small notebook. Currently, the size of a notebook hard drive split into two second 5-inch and 1 8 inch, 2 5-inch notebook hard drives have reached the maximum capacity of 80GB has is often widely used in notebook computers, and 1 8-inch notebook hard drive capacities up to 40GB, appearing speed only 4200, upgraded by some ultra-light notebook Dell Inspiron 9400 battery (eg R100 Toshiba, Sony X505 product of intense light), expensive, difficult to Auch.
Mobile Display Chip:
By increasing the power of notebook computers, a gaming entertainment notebook has become. ATi Mobile card on the field also remains the world, although catching the Rising Star nVidia, but overall power consumption and performance is slightly behind ATi. The current most powerful mobile graphics card came as a ATI Mobility Radeon 9700 and nVidia GeForce FX Go5650, although not the performance of two powerful graphics card, but the power consumption is small, often in mobile multimedia, centric notebook or desktop computer instead of product based computer, searching for 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 are good 4 Geforce Go440 mobile graphics chips, the performance of repairs: Mobility Radeon 9600>; Geforce Go5200> Mobility Radeon 9000> Geforce Go440> Radeon Mobility, strength, and performance is usually inversely proportional, so that they appear in different models of orientation.
In addition, show that the notebooks there is a place to be reckoned with, this integrated graphics, they are the lowest energy consumption, but also a good 2-D display, and so business-notebook, thin and light notebooks in general, when, or even the display area, the most important absolute. Recent major integrated graphics chips kind 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. 855GME chipset, Intel’s latest integrated graphics chip, performance is the level of the ATI Mobility Radeon 7500, is the leading integrated graphics chip chipset. You should also video memory are integrated graphics chip main memory as video memory to be checked by memory sharing, influence in determining the size, too small to power the display, too much is consumed leading to the main memory through main memory little impact on the overall performance.
Network Equipment:
Laptop Notebook Computer network equipment is one of the ultimate configuration will be, is the active promotion of its Centrino “unlimited wireless” (wireless LAN standard), but a huge success, now comes with a standard V92 modem, laptop and 10 / 100M Ethernet may bring adaptive map, the minimum requirement for the network equipment is standard notebook, the user has finished paying attention during the purchase of two facilities, or use a lot of future trouble. In addition, the popularity of Centrino, wireless LAN standard to a feature of the notebook, now most of the high-end notebooks are equipped with wireless cards, giving users a high degree of convenience, wireless networking, routing, many public seats are equipped with wireless LAN, a laptop with a wireless card, extreme comfort, the course is, wireless LAN standard machine brings to update the cover price, but for HP Pavilion zd8000 battery of future upgrades, standard wireless network card or a cost-effective.
Display:
Notebook display can be one of the most important part of the screen size directly affects the size of laptop-size, the current type of notebook will be divided: 8 9-inch mini-notebook, ultra-thin 10th 6-inch notebook, 12 1-inch thin and light notebook PCs, 14 1-inch notebook full size, 15-inch and 17-inch desktop replacement notebook computer. Therefore, the size of the screen the user decide to see a key factor in the notebook, what kind of laptop you need. Display or notebook computer consumes large, but also determines the power consumption of notebook usage time, and this directly affects the image quality notebook user emotions, so a good display laptop users buy when they watch their steps.
Notebook Purchase points:
was, in fact, many laptops buy on impulse when a friend threw buy to go, anxious to begin before the purchase and not to analyze their own needs, not understanding the various functions in notebook computers, feel what the future purchase of products is not as good in their own welfare, never regretted the decision below.
Rational purchase of notebook computers before a full assessment be made, is both for their own needs or characteristics of the product to a clear understanding and buy a lot of users if they do not, but listen to advertising or other persons side of the history, one-sided pursuit of model weight, appearance, brand, etc. Finally, Do not buy products for themselves and made unbearable problems.
The notebook computer products and everything else is not perfect, but the needs of each user is different, but each laptop position is not the same function, only understand fully their product requirements and product characteristics, the elections products Apple M7318 battery was purchased money specifically to buy the most reasonable best suited to their machines.
Ask yourself at the end do not need notebook
First, ask yourself what you want in a laptop? If you try to show it is still recommend that you immediately scrap the whole idea, updated notebook product very soon, maybe you buy your laptop in yuan is reduced after six months out of things, What can you regret your last million for the to pay costs.
If you are not completely familiar with computers, are used only at home, choose the laptop is acceptable, but you need a laptop half the price you can consider buying the outstanding performance of the other, not other aspects of the desktop, but also convenient future upgrades, so we think you should be the preferred desktop.
What kind of people for the purchase of the notebook? Of course, if you work your notebook, study and live more comfortable and pleasurable, you can not hesitate to choose him. For example, frequent business travelers, students in college, computer programmers and second family.
• understand their own needs
You at the end, what a notebook? Primarily for what it does use? You just know these two issues, you do not buy products aimless, confused. If you are a business person, often on the road, then a Wending light business notebook is the best choice is: If you are a student, you can pay more attention, but the style is in fashion from each favorite youth, so I is some low-end multimedia functions for a powerful laptop, the performance of all aspects of the book take good look is more stylish, but students do not need to bring to the laptop, so the weight can be a more robust, so prices have to require more decisions: If you choose an office or home with a laptop, with great comfort and total high-performance desktop replacement notebook is your ideal choice. Of course, everyone needs a complex and diverse, ultra-thin notebook, emphasizes multimedia notebook audio-visual features for various applications introduced, unless the user to consider seriously before buy this issue, I think you will have about the direction and then again in selected areas of the specific characteristics of each product, the best option for their products not be difficult.
Clear own budget
Laptop prices vary widely, even in the same position, configured essentially the same product, different prices for the brands have different phenomena Pole to choose, therefore, to its new budget laptop also very important to do, and not the budget then.
And the budget, the best prices of the two, is an ideal price, you would like a (CAN) afford the highest price. If the actual purchase, first used at great prices, and only really find the right model, but more expensive, it is the highest price, the Eee PC battery to assess in each case, be no more than their maximum price and not on the recommendation the sales staff and installation of open standards based, so the final product you can buy your load, because the function does not need to pay a high price.
And the determination of the model after purchase, preferably as far as possible to determine from various sources on the prices of goods on the market at a realistic price and then ask where to buy business, ask not to lose a few, at the end most are a bargain, the actual transaction price is typically lower than the price of the business 50-10%, depending on your ability to negotiate. If the price of quality can be fired if the price is not satisfied, no hurry shots, after all, the price of the notebook always fall, there is always more than a few times a surprise.
Summary:
Notebook computer has a wide range of products, users have to clear before buying their purchase intentions to keep the principles of good enough, do not blindly follow the latest technology, the next most fashionable style, the most efficient performance, and brand awareness to make a rational analysis, rational choice, their own choice in a satisfactory product.
In addition, the domestic notebook market is not ripe, notebook computer sales service is a headache. So before you buy, you must pay attention to the problem and treat it as an important factor when buying the machine, choose a good brand reputation, fill a clear time of purchase certificate, a great warranty to determine the time, so much as possible for the maximum duration of the warranty, so that the users use the notebook from the rest
