One more thing, I hope the landlord will consider the second ASUS I recommended, which is really cost-effective. I put it in the second recommendation only because his screen is a little bigger ~ ~ ~ ~ ~
As for the problem that should be paid attention to when buying a laptop, that is to prevent profiteers from playing tricks. Hehe, first of all, you should look after the computer at home, find your favorite computer information on the Internet, especially the price, and don't fight unprepared! The profiteers use this ~ ~ or use it to charge and sell it to you with a refurbished machine, not a new one. I attach a notebook inspection method at the end of this paper, which can basically prevent this problem ~ ~ ~ or they can deduct gifts (such as antivirus software and keyboard cover). This is easier to prevent, just ask a few more questions. The last one is the blackest ~ ~ Some merchants know the price of the machine very well after you quote the model you want to buy, so it is difficult for them to make a big profit, so after asking you to pay, they give you a machine that makes you dissatisfied (that is, a faulty machine) and then recommend a machine that you are not familiar with. At this time, you have already paid the money, so it is obviously impossible to ask him for a refund. As a result, you know it's a complete set and you have to. ! ! Also, when buying a laptop, you'd better bring a friend who knows more about laptops ~ ~ ~

New Year's Day discount is inevitable ~ ~ If you want to buy on New Year's Day ~ ~ Don't forget what I said ~ ~ Ask what gift to give ~ ~ lest you be deducted by profiteers ~ ~

Inspection method of notebook computer
I. Unpacking inspection:
A brand-new machine will have a complete and regular packaging box, and some brands of products will also have multi-layer packaging. The bigger dealers are very strict and must pay before unpacking. Don't complain, to some extent, you can guarantee that the machine you bought is not left over by others. The screen, keyboard and other parts of the new notebook computer are covered with protective film or other forms of packaging. You need to check whether these packages and protective films are perfect and clean to ensure that you must buy a brand-new machine.
Second, the parts inspection:
After unpacking, first check whether the machine model and all accessories (such as instruction manual, warranty card, system recovery CD, power adapter, patch cord and other attached software CD) on the packing list are in line with the actual situation. It should be noted that in the new laptop packaging, the battery and the machine are packaged separately, so you need to pay attention to whether the metal contacts of the battery are scratched. If there are scratches, the battery has probably been used/replaced.
Third, the appearance inspection:
Appearance requires careful inspection of the surface for scratches, breakage, cracks and other defects. The inspection process should be comprehensive, and the front, back, side, keyboard, touch pointing device and even various interfaces should be carefully inspected. Need to be reminded that you need to check the information on the self-adhesive label on the laptop base, which is generally printed with information such as origin, model, date and serial number. Pay attention to whether it is the model you specified. If the factory date is too early, it is necessary to check more carefully whether it is a prototype or a refurbished machine (exhaust port, foot pad, rotating shaft, keyboard gap, optical drive, battery compartment metal film, metal contact with dust/traces). The appearance manufacturing process can not be ignored, such as checking the close connection between the optical drive and the fuselage; Open and close the display screen several times to see whether the axis of the screen rotates flexibly and correctly, and whether the seam between the LCD screen and the frame is tight.
Fourth, screen check:
LCD screen is an important part of notebook computer, which is expensive and fragile. First, observe whether there is dirt, scratches or cracks on the screen surface. After confirming that the screen is in good condition, open the wordpad that comes with the operating system and check whether the brightness of the whole screen is uniform under different brightness, paying special attention to the four corners and borders. Generally, the central brightness is normal and the four corners are dark. Then open a self-contained color picture and check whether the color of the LCD screen is off color. A simple way to check the bad spots of LCD screen is to set the desktop background to white, black, red and other monochromatic colors in turn. If you find that a point is not bright (black) or always shows a certain color, it is a bad point. It is best to use DisplayX and other software to check whether there are any display defects such as bright spots or bad spots (no more than three) on the screen of all white, all black or all red, all green and all blue. Also check whether the brightness and contrast adjustment of the laptop is available. In addition, "water ripple" is also one of the problems worthy of our attention. We can gently press on the top cover side of the LCD screen to see if water ripples are easy to appear. If it is easy to appear, it means that the shell strength is not good.
Verb (abbreviation of verb) View configuration: (Attached with Lenovo notebook configuration parameters, you'd better take it with you when buying, so as to view it)
After checking the appearance, you need to check whether the configuration of the machine is consistent with the nominal product. The simple way is to check the "general" properties of the "system" in "My Computer" after booting, and the information of memory, graphics card, CPU and hard disk will be displayed. Another way is to enter the BIOS of the machine and check the details of the laptop configuration. There is a serial number on the body of any notebook computer (usually a small label marked with serial number is attached to the bottom of the machine). Copy this serial number down and enter the BIOS to see if the serial number in the BIOS is consistent with the serial number on the back of the machine. In the BIOS, you should also pay attention to an option called "UUID" (not all laptops have it). The number after this option is the serial number of the motherboard. If the serial number is found to consist of a long string of 0s, it means that the motherboard of the notebook computer has been repaired or replaced. You can also use software such as Everest to test whether it is different from the published data parameters. Through CPU-Z 1.22 software, you can check the CPU main frequency, system front-end bus frequency and other parameters. Power adapters must not ignore their original compatibility.
Six, check the performance:
Don't bother to check the performance of the machine. Run the software commonly used in XP to see if it is smooth. Check the play/burn function of the CD-ROM drive to see if the CD-ROM (violent and colorful movie) is smooth; Display color pictures to check the performance of the graphics card; Play your familiar MP3, listen to it with headphones and stereo respectively, and see the performance of the sound card; Fan operation (the notebook fan of Centrino CPU should be started every 20 to 30 minutes and stopped for about five minutes to save energy), noise and machine heat dissipation; Whether the interfaces are in normal use.
Seven, warranty procedures:
When purchasing, you should not only know the contents, terms and years of warranty, but also keep all kinds of stamped documents, such as invoices and warranty cards. In addition, you need to know whether the supplier of machine warranty service is a manufacturer or a distributor.
I hope you are satisfied with my answer ~ ~ ~ Finally, I wish you an early purchase of your favorite computer ~ ~ ~ Hehe ~ ~
