Frequently asked questions and dispel doubts laptop purchase
Frequently asked questions and dispel doubts laptop purchase
Multi-user when friends do not like to buy books over split sealing machine is mainly worried about experience repairing machines or dealer manipulated replacement parts. Dell Inspiron 6400 Battery But in fact, no demolition had closed the books often encounter, such as the prototype only put a few days, such as open to other users just seen the goods, etc., does not mean that these machines have a problem, is entirely feel comfortable buying the machine. Good care of those letters was inside did not open the books are not necessarily over, because a hairdryer can be solved completely seal packaging books, without leaving any trace. Therefore, the time to buy books, buy a new machine, but it does not mean that a good seal also must be close to the books on the new machine, it does not mean split-off boxes of books can not buy. The key is whether the books are not new machines. Below and we said a few identification books is not new machine tips:
1, see the serial number. Most of the notebook body and the battery should be affixed to the same serial number and, if the battery serial number and serial number of the host are inconsistent, books most likely to be replacement battery; In addition, the procurement of foreign brand products, notebook computers, whether the body and the battery and the serial number on the packaging line to test whether the product is a very important parallel basis, to be known abroad, parallel notebook is not in the country enjoy the warranty.
2, see security keyhole. If there is imprinting, indicating insertion of notebook security lock, most likely done prototype;
3, the bottom feet. If there are worn and dirty, indicating been used, the production line of table not that dirty;
4, see the Cooling Fan. If the blade has a thin dust, and shows up for a week or more using the As;
5 to see the production date. Three months ago the factory's books are still sold in the market, we should pay attention. Fast electronic product sales update, can not get a press books for so long in the channel in the.
6, looking at the keyboard. The keyboard is very clean, new books, but not shiny. Used books will dust the keyboard gap, often a few key sub will be worn shiny;
7, see the screw. This is not to say it? Screw demolished over? It was U-turn Fujitsu Lifebook T4020 Battery on the go!
8, to see cracks. Was renovated in the books dealing with, such as the gap is generally difficult to deal with the new, such as books screen small gap between the AB surface, such as optical drive slot, and PCMCIA cards MODEM even inside these interfaces, if you can find the fouling , you can be sure whether it is to be put off prototype, and not sealed. What? Also found a clean cotton silk fat used books? It is also used then I asked how you should do?
In short, read books is not new machine, it can not be generalized outside the box was opened. Are not opened are not necessarily good books, on the contrary, are generally the most reliable sample books. Daoshi good package of books, we must be careful to distinguish them. When selecting the most important is careful.
Second, bad points - the number of operators more ah?
A good tool for detecting dead pixels screen-NOKIA Ntest
LCD screen, buy a notebook the most headaches is dead pixels, after all, no one was willing to buy your new notebook there is some big bright spot, right? Vendors promise but hardly no dead pixels. ASUS notebook vendors, only promises no bright spots, but we can go to ASUS forums to see, it is just word games, more terrible dark spots, also can not stand ah! And they point to a color as color, either bright spot can not protect, so now the standard by doing we highlight what is really hard to tell.
Problems LCD's dead pixels LCD industry a long time, due to manufacturing their own reasons, LCD's dead pixels is difficult to avoid, but the number of dead pixels is normal for it. Current LCD manufacturing sector has never given an explanation, in the end the number of dead pixels is normal, in fact, there is the bad points of the body of a single crystal liquid crystal display does not work, there may be red, blue, green, different defects.
Bad points are rooted in the emergence of production, if problems with transportation or use for a long time to answer all appeared in the stall. Because of dead pixel LCD screen in crystal form had doomed the moment, only some of the time did not appear at the factory, or some of the problem is not serious, and only after a period of time in the use of dark spots gradually turned into (light dark) . In other words, bad points less likely to produce the day after tomorrow. So get a dead pixel in the books, do not have to worry about dead pixels would be spread.
LCD screen for dead pixels, it is helpless in the topic, in general, buy the books of the time, had three dead pixels on LCD screens, especially in A, there is dead pixel, you can refuse to HP pavilion ZV6000 Battery buy. When in the selection of books, here proposed we can take some screen test software to conduct detailed tests on the screen, be sure to choose carefully before you buy to avoid unnecessary trouble in the future.
Third, the fan - it should not turn in the end of the?
Notebook Cooling tools - fan
Notebook and desktop computers is not the same fan is temperature controlled by the laptop (some individual other than the desktop CPU notebook). In other words, high temperature, the faster the fan will run, low temperature will slow down and even the fan does not work. One advantage of this power, and second, noise reduction, third, can be extended fan life. In general, the Notebook Fan speed can be set in COMS adjusted by adjusting the power saving mode. Some notebook COMS setting the more the whole, can set the temperature and Fan Speed. Some friends too noisy laptop fans, fan always want to stop working, the fan start temperature adjustment is very low, it would be overheating CPU and system temperature, leading to crashes and reduce the service life of related components, is no good, So, Notebook Fan, frequently turn bad, do not work too negative, need to acquire a degree.
General experience is at room temperature 20 degrees, when a well-ventilated room, Internet browsing, Centrino notebook CPU Fan should be separated from 20 to 30 minutes in the start time, working for five minutes stopped saving. When playing the game, about ten minutes once started. If the normal operation of the work has been crazy, you should check for a set or COMS is not a problem with temperature control circuit.
4, the keyboard - Sha is the feeling?
Notebook keyboard with a Chinese label
Many friends and some media tests in the evaluation room will say so and so's keyboard feel to how, in fact, this is the most difficult to measure word of. Laptop keyboard key way short compared to typical desktop keyboard a lot, in itself is very uncomfortable. So do not feel too good. And each person the flexibility of software and hardware for the keyboard keys have different preferences, so simply use their own feelings of how to handle the keyboard is not objective.
A good laptop keyboard, in order to:
1 foot gap, generally below 12-inch notebook, the keyboard often with tight design, close proximity between the keys, playing word uncomfortable.
2, key prison, some bad laptop keyboard keys, according to a corner, another corner or even turn up to, so playing word, key rickety, it is difficult to bear.
3, the overall level, notebook keyboard, thin, often installed with the following notebook Dell Inspiron 8600 Battery memory, Hard Drive and other accessories, laptop keyboard below the design of some irregular in some places there are accessories, some areas are empty, plus the keyboard itself is lined thin, when typing the bottom where there will be no settlement accessories feel not only uncomfortable, or even felt by fall, according to the horrors of bad feeling. Those from low-angle head-up the past, and even can see the keyboard is the wave-shaped, very smooth. This keyboard is more frightening is that books high temperature work, the keyboard will muster up a little, but together on screen after shut down, summon the keyboard has not returned in situ, but friction LCD screen, resulting in LCD screen and keyboard layout printed on the same scratch and can not repair, will also affect the warranty. As very serious consequences.
4, poor layout, lack of a small number of key notebook keyboard, where it is compact, so the keyboard layout is different, some very unreasonable laptop keyboard layout, a number of function key settings all over the place, hard to find, type and use of inconvenient time. I used a WIN button to move to the upper right corner of the Toshiba laptop, and it felt extremely awkward the.
5, configuration - smoke and mirrors.
Smoke and mirrors of the notebook configuration Single
Many friends often ask me, certain types of notebook memory frequency is the number, how many rpm Hard Drive, motherboard chip, etc. What is the specific configuration, this really is powerless, unable to answer. Now the notebook production, due to the arrival of the upstream parts manufacturers are inconsistent, while the production line can not be expected to stop work, so basically without violating the commitments and below the configuration information based on the use of existing parts to assemble. So if you encounter the low-end notebook hard drive to install the 4200 switch to early arrival for high-end books are not installed to 5,400 RPM drives, and high-end books have been produced on the line, only a thin disk, then the 4200 RPM drives will be installed to high-end notebook, the lower end of the late 5400 books but were using high-speed hard drive. Memory also do so. This will give the various batches of different products, the configuration may change phenomenon. For there is no public commitment to the Hard Disk speed, memory frequency and size of the notebook Motherboard Chipset, manufacturers can make a configuration according to the actual circumstances of adjustment, for consumers, could feel a headache, but in the absence of a better solution Until that time, only as far as possible subject to the actual configuration of the spot, in particular, the configuration should not have to listen to media evaluation, and to its commitment as a manufacturer.
6, the battery - how can how long?
Laptop battery
Laptop battery life is a big problem, if no batteries, notebook we do, do not buy a desktop LCD computer such as what to buy books, to have a mobility. Then use the standard battery is it? Under what circumstances how long regarded as normal? The maximum life time of the so-called standby time are what mean? Laptop now, are basically using the lithium battery, the benefits of the answer is very clear. However, the number of cell batteries, laptop power saving mode configuration and the circumstances of the battery are greatly affected. In general, a laptop, the battery is fully activated case, at full speed under the circumstances, should be able to ensure supply of more than two hours to be normal. Note that the battery life of the battery charge and discharge by the number of very serious impact. Therefore, to minimize the frequency of battery charge and discharge, for extending HP Pavilion ZD8000 battery the battery life of notebook computers is very good.
7, lower frequency - it ye on the down-out?
Using Speedstep Pentium M processor energy saving technology
Some of our friends in the purchase of laptops equipped with mobile processors when there are often plagued by a problem that is often not achieve the nominal processor frequency, the frequency is always lower than the nominal speed of operation, some friend on his laptop that is a problem, in fact, this phenomenon is not much tension. As the notebook product is different from desktop processors processor, notebook processors for these energy-saving considerations, most used, such as Intel's "Speedstep" and AMD's "Powernow" technology energy-saving technology, the processor can be used by state analysis automatically reduce the frequency of use, so as to achieve energy saving. If the status of the use of low frequency words, use your influence, you can turn off the power saving features inside the BIOS to set the options and to adjust the Power Options properties has been open, so even in the battery case, the processor will run at full speed, of course, battery life will shorten the response, after all, can not have both fish and bear's paw Well.
