almost every day with friends, or friends of friends ask us about the purchase of notebook computers, of course, everyone's needs are different Ibm Thinkpad T500 Battery, but we found these consumers before buying is widespread doubts, asked questions are also very straightforward--I want to buy a laptop, what to buy? We cannot directly give our views on a different user, if you have such a problem exists, you may wish to take a look at some of these simple suggestions:
1. Want to better your needs and working environment--is often carry, or 2.1 lines dell vostro 1000 battery, or simply placed in the home; is only used to typing, or do you want to play the game; is focused on multimedia performance, and appearance is more important. After that in mind, it identifies you to look at what kinds of products.
2. According to our experience, the vast majority of consumers buy notebook just for the basic word processing, Web browsing, sending and receiving mail, notebooks are capable of this task now, but at least 30GB per cent of the hard drive.
3. Best has 512MB of memory. More memory can better improve performance under the premise of low-cost.
4. Consider a rewritable CD drive, CD-RW or DVD-RW will do. If you want a rewritable DVD optical drive, it is best to select multiple format support both DVD-R and DVD+R Flash drives, but higher price of such products.

7. As for second hand laptop, domestic markets are not as foreign as standard, so try to dispel the idea, but if the person who sold you the computer is your friend, and understand the degree of performance of the machine and the old and new, can also be considered.
8. Before purchasing laptop must inspect the product after-sales service provisions, possibly longer service can be purchased, DELL does a good job in this.
9. For some products Dell Inspiron 9400 Battery, with the port adapter or docking station will facilitate many, but these attachments are not cheap, wise to choose as needed, not to spur on the Pocket.
10. If so requested, may wish to consider the annex to the standing offer, such as an external mouse, safety locks and automotive power DC-AC converters and manufacturers present annex must take. Do not underestimate the computer package, manufacturers will provide specially designed computer packages according to their own products, it will provide the most comprehensive protection to laptop
first, first thing to do: read specification sheets.
read specification sheets
we have prepared a veryRepresentative specifications of table here as an example (see right):
in this specification in the table, from top to bottom is divided into 4 parts, respectively, is the recommended configuration, technical specifications, the bundled software and optional accessories.
recommended configuration was adopted for the product name and model of the main part, such as "platform" column cheap laptop batteries, you can see this product adopts the Centrino (Centrino) dual-core mobile technology, which used the latest Napa platform, in the Napa is also listed in the specifications table of notebooks with the processor, chipset and wireless network specific model. In some of the other specifications of the product table, may also put the processor, chipset and wireless network list.
in recommended configuration column in, usually also will contains screen, and display card, and optical drive, and hard drive, and memory, and battery, and weight and so on information, this which need note of is "can selected", and "maximum support", and "most long can up", words and data Hou brackets within of content, because these things is most with confused sexual of, it representative with you may get, but in current price Shang may does not provides of things, or is you in a species situation Xia only to get, is not always so. Strict Manufacturers Association in these uncertainties on the data with the number of labels, and in the specifications table below in accordance with the detailed description and interpretation of numerical index. To we of experience view, notebook computer of battery life and weight data is most has dispute of part: usually notebook computer manufacturers by standard out of battery life, is in accordance with the must of standard test came of, this standard often is in the province electric mode full, and screen brightness adjusting to more dark state, therefore its numerical representative has you may get of battery life of maximum value, if you of using load is heavy, operation is frequently, notebook computer no opportunities sleep and standby, and processor no opportunities for drop voltage and frequency, and close cache, province electric action, and you need keep screen brightness maximum, so you may get of battery life only nominal value of one-second JIU one-third. In the latter article, we will provide you details of how we tested the battery life. In weight this a item in the, manufacturers numerical callout often also has many skills: first is match different capacity of battery, will zxcsky32645 caused weight of changes, 3 core battery will than 6 core battery light 150g around, 8 core battery is will than 6 core battery heavy 100g around, even some manufacturers by standard out of weight is does not containing battery of; second, optical drive is Assembly on weight also has obvious effect, removed battery for Shang a a reduction heavy device (Weight Saver, actually is a bezel), also will makes machine weight reduce 150g to 200g. To give you a more accurate understanding of the weight of the product, in our tests will use high-precision electronic scale to actual weighing each product, weighing, contains a standard configuration of the battery and optical drive (non-optical drive external models).
next we'll take a look at technical specifications: in this section, usually is more detailed and some of the items listed, usually, the 90% of which many users have not seriously. However we believe that this part is equally important, only tell you what parts are used in the recommended configuration, while technical specification tells you in these parts is good or bad. Such as a hard disk, 100GB configure tables only tell you, but you do not know the interface type and speed of motor, and in the technical specifications in the table, you can see the words SATA-150, 5,400 rpm, which represents the hard disk using the latest interface, and is a mainstream speed, performance is guaranteed. Another example interface section, you may be concerned about whether it has several USB 2 interface, IEEE1394, s-video output, you can find the answer here. Could you also care whether the machine has Bluetooth, wired and wireless networks support what speed specifications, responsible manufacturers are listed in the technical specifications of the above projects.
in part of the bundled accessories, you can usually see what software this laptop preinstalled, some manufacturers will put the preinstalled operating system versions in this part (in this case is on the recommended configuration section). Famous brand of notebook computer usually equipped with following type of software: media play class (as PowerDVD), and CD burn class (as Nero, and RecordNow!,), and anti-virus software (for example Norton Anti Virus), and eBook reading software (Acrobat Reader), and audio graphics, multimedia processing software (Image Ready, and Power Producer,), in addition also may has and with brand other device of communications management software (for example Sony VAIO notebook computer, on provides has and DV, and carry listen to and so on consumption electronic device related of software). A unique preinstalled laptop software, is the product of value, such as a laptop that comes with ThinkPad laptop management and setup software, you can greatly improve the efficiency and management level of equipment.
in addition to the software, some hardware annexes may also be included in the bundle columns, such as power adapters, extension card, remote control, and so on.
in the specification sheet of the last, the manufacturer also tends to give a list of optional accessories, often including extended base port replicator an external optical drive, second battery, hard drive, floppy drive, mouse and even backpacks. These parts are not standard, if you have additional needs, you can also purchase.
on the LCD screen-how to buy, I give you my opinion here, at the time of purchase it is important to use some software test test highlights, yet of a liquid crystal display manufacturers guarantee that no bright spots on the LCD, only is the ASUS, but to his products on the Forum to see, problems with a bunch of LCD products. So guarantee can only be described as empty words, this is determined by the characteristics of the LCD is itself. Generic test result of less than three is acceptable, if three or more I advise you to hurry to leave or change machine.
next to on an important electoral experience, number of profiteers take some computer city now return machine and sold again after renovating machine packaging consumption (one word, is raped) to deal with this situation you have to take a look at the following aspects:
actually purchase notebook has many aspects of factors to consider:
first to know own buy of notebook to with in which aspects, as see film can consider screen is light screen of, also has sound card quality to superior; is Office supplies, so first to consider to battery of continued using time, wanted to wanted to, if power occurs in important of conference room in, suddenly power, and you next to told of things also has many, this will you the do? Then if it is to play the game, requires the video card, memory and CPU to have the ability to phase.
1. Laptop with the battery model to be consistent, otherwise most likely to change the battery.
2�� Keyboard light without light, which are generally effects of dust on it cleaned.
3�� Fans near the visible dust, this is the effect of the notebook spent over a week.
4�� Notebook pad below if there is dust, general production workshop is not a dust.
5�� Attention to screws, and whether there is a gap between notebooks with screens, optical drive and whether there are gaps, appears above, change machine, and needless to say.
