Dell's best-selling computer in the 5,000 to 6,000 yuan price range Price 5600 yuan

Reiterating a nagging word, I hope the owner to consider my recommended second Asus, cost-effective really high, the reason why it put it into the second recommended, just because his screen is slightly larger ~~~~~~~

As for the purchase of laptop computers to pay attention to the issue of well That is to prevent the treacherous business The first thing you can do is to look at your computer at home, and get the information you want on the Internet, especially the price, not to fight the battle of the unprotected! Adulterer's tactics used to go is that kind of ~ ~ ~ either this is good, with refurbished machines instead of new machines sold to you, this I will attach a laptop inspection method at the end of the content to do in accordance with that can basically prevent this problem ~ ~ ~ or is the withholding of freebies (such as antivirus software, keyboard covers and so on) to prevent this is easier to ask more than a few people on the good. The last kind of blackest ~ ~ ~ some merchants after you reported that you want to buy the model, see you on the price of the machine is very understandable, so it is difficult for them to have a big profit, so they let you pay money to give you a machine that you are not so satisfied (that is, there is a problem with the machine), and then recommend you a machine you are not familiar with, at this time you have already paid money, ask him to return the money is obviously impossible, the results! You know that this is a full set and had to jump, for this tactic, you just insist on the first inspection and then pay money can be avoided ~ ~ to always take the initiative in their own hands ~ ~! Also, you'd better bring a friend who knows more about laptops when you buy one ~~~~~

------- ---------- ---------- ---------- ---------- ---------- ---------- ---------- -------

Discounts on New Year's Day are a given~~~If you want to buy on New Year's Day~~~Don't forget what I said about asking a few more people~~~Ask what freebies you're getting. ~~ Ask what freebies are being given ~~ lest you be deducted by unscrupulous traders ~~~

------- ---------- ---------- ---------- -----

Laptop inspection methods

One, open the box to check:

A brand-new machine will have a complete and neatly packed box, some brands of products will also have a Multi-layer packaging, some of the larger dealers are very strict requirements, you must pay money before you can open the packaging, you can not complain, which to a certain extent to ensure that you buy the machine is not someone else to pick the "leftovers" under the. New laptops in the screen, keyboard and other parts of the protective film or other forms of encapsulation, you need to check these encapsulation and protective film is perfect and clean, to ensure that you buy must be a brand new machine.

Two, accessories check:

After opening the box should first check the packing list of the machine model and randomly attached to all the accessories (such as manuals, warranty cards, system recovery CD-ROM, power adapter, adapter cable and other software CD-ROM attached to it) is consistent with the actual situation. It should be noted that new laptop packaging, the battery and the machine are packaged separately, you need to pay attention to observe the battery's metal contacts have no scratches, if there are scratches, the battery is likely to have been used / switched.

Three, appearance check:

Appearance need to carefully check the surface for scratches, breaks, cracks and other defects, the inspection process should be comprehensive, front, back, side, keyboard, touch pointing device and even a variety of interfaces should be carefully checked. Need to be reminded that you need to check especially after all the information on the sticker on the base of the laptop, usually printed with the origin, model number, date, serial number and other information, pay attention to is not the model you specify, the date of shipment is too early to be more detailed check to see whether it is a prototype or refurbished machine (air vent, foot pads, near the spindle, the keyboard gap, the CD-ROM drive port, the battery compartment, the metal film, the metal contact with or without dust/prints). ). Appearance of the manufacturing process can not be ignored, such as checking the optical drive and the body of the joint degree of tightness; open and close the display a few times to see if the screen spindle rotation is flexible and appropriate,, the LCD screen around the border with the joints are not relatively tight.

Four, screen check:

LCD display is an important part of the laptop, expensive and relatively fragile. First observe the screen surface with or without dirt, scratches or cracks, to determine the screen is intact, open the operating system comes with a writing pad, in different brightness to view the brightness of the entire screen is uniform, pay special attention to the corners and borders of the part, the general center of the brightness of the normal and the corners of the darker cases. And then open a self-provided colorful pictures, check the color of the LCD screen whether there is color cast. LCD screen to check the bad points of the simpler method is to set the desktop background in turn to white, black, red and other monochrome, if you find a point does not light (black) or always show a certain color, the point that the bad points. It is best to use software such as DisplayX to check for bright or bad dots (no more than 3) and other display defects in all white, all black or all red, all green, all blue screens. Also check to see if the laptop's brightness and contrast adjustments are available. In addition, "water ripples" is also one of the problems worthy of our attention, we can be in the LCD screen top cover side of the light hand pressure, to see if it is easy to appear water ripples, such as very easy to appear, said the shell strength is not good.

Fifth, check the configuration: (with Lenovo notebook configuration parameters, it is best to bring in the purchase, in order to check)

After checking the appearance, you need to check the configuration of the machine is the same as the product labeling, a simple method is to start the machine, in the "My Computer" view "System" of the "General" properties, will display memory, graphics card, CPU, hard disk information. Another method is to enter the machine's BIOS, check the laptop configuration details, any laptop computer body has a serial number (labeled with the serial number of the small label is generally affixed to the bottom of the machine), the serial number copied down, and then enter the BIOS, check the serial number in the BIOS and the back of the machine whether the serial number is the same as the back of the serial number. In the BIOS, should also pay attention to the name of a "UUID" option (not all laptops have), the option behind the number of the motherboard serial number, if you find that the serial number consists of a long string of 0, it shows that the laptop's motherboard has been repaired or replaced. You can also use EVEREST and other software tests to see if there is any difference with the published data parameters. Through the CPU-Z1.22 software can view the CPU main frequency, system front-end bus frequency and other parameters. The power adapter must not be neglected in its original configuration.

Sixth, check the performance:

Check the performance of the machine do not be afraid of trouble, in XP to run commonly used software to see if it is smooth; check the optical drive playback/burning and other functions, play the CD-ROM (action is more intense, colorful film) is smooth; display colorful pictures to check the performance of the graphics card; play their own familiar MP3, respectively, the use of headphones and Audio listening to see the sound card performance; fan operation (Centrino CPU laptop fan, should be in every twenty to thirty minutes to start once, work about five minutes to stop working energy saving) conditions, noise, the machine's heat dissipation; whether the various interfaces are normal use.

Seven, warranty procedures:

We not only need to understand the content of the warranty, terms and conditions, years, etc., but also need to retain a complete seal of the various documents, such as invoices, warranty cards, etc., in addition, you need to be able to clarify the machine warranty service provider is the manufacturer or distributor.

I hope you will be satisfied with my answer~~~Finally, I wish you to buy your favorite computer soon~~~Ho~~~
