1, check the package
To get your favorite notebook, you must first look at whether the packaging is intact and whether the relevant accessories are complete. There is always a list of accessories (accessories) in the box of regular brands;
2. Check the appearance
Check for scratches, paint loss, intact appearance, shaft damage or looseness. If it is a notebook, it is also necessary to check whether the mold has problems such as loose bite or fine seam;
Step 3 check the serial number
The fuselage, battery and charger, outer packaging box and warranty book, generally, the fuselage, outer packaging box and warranty book will have the same serial number;
4. Check the details
Whether the relevant interfaces are clean and dust-free and whether there are traces of use, if so, be careful, and it is best to ask clearly;
Here is mainly to check whether it is a prototype, a refurbished machine or a rework machine;
5. Screen detection
Here, it is very important to use special software to detect the color quality displayed on the screen (such as DisplayX, Nokia Test, Master Lu, etc.). ), whether there are bad lighting points, etc.
6. Configuration detection
Check whether the configuration parameters are the same as those on official website or related professional websites. There is always a configuration list at random (this is very important), so it needs to be checked correctly. Sometimes the configuration parameters will be slightly improved with the update (the configuration list of the machine and the random tape should be the same).
7. Testing of each interface
Such as USB, RJ45 network port, card reader, E-SASA, VGA port, earphone port, microphone port and video head.
8. Systems and software
For example, if you want to change another system or install any software, the general merchants will try their best to satisfy it. (If there is a genuine system, ask if there is a serial number, and some will be posted on random paper attachments or directly sent to the CD).
9, machine performance testing and inspection
All the above steps are fine, and you need to take them home (you can also test them in the merchant if you have the conditions); If you have difficulty, you can directly ask the merchant for a PCMark2005 or directly use Master Lu's performance test, run it again, and check it with the online data, and the difference is not too much. The focus is on the performance test results of the hard disk, whether it is normal (such as reading and writing speed, random access time, health status, etc.). ).
10, Temperature and pressure test of computer copier
The temperature and pressure were measured by Master Lu at 10 min, 20 min and 30 min respectively. Generally, it is safe within 80℃, but the lower the better. If it is extremely abnormal, you should contact the dealer. If the temperature can be controlled, it shows that the heat dissipation performance of the computer is very good and the service life will naturally be longer.
1 1, professional copying software test of computer copier
Here you can basically detect whether there is a problem with the hardware. After this step of testing, your laptop is stable and reliable, and you can use it with confidence. You can choose which copy software to use, and the best copy time is 1 hour.
12, battery capacity test of the machine
Please pay attention to your power scheme. Mainly screen brightness and processor power management, the battery life will be significantly improved after setting! Also, don't wait for the battery to run out in the future. It is not good for the battery when charging. Fully charge the machine, and then take the notebook to read web pages, chat, watch movies, work and other normal use (can cooperate with the next network test).
13, wireless network test
Use it in every room. Go online to see the stability of wireless network connection. Here, all the inspections have been completed, and all that remains is to have a good habit.
Question 2: I want to buy a computer now. What do I think about computer configuration options? Keywords cpu, graphics card, memory, cache speed,
Question 3: How to check the configuration of the host? Security software generally has this function.
There are also optimization experts.
Look at the test results of my QQ computer housekeeper.
Question 4: How to see whether the computer is running and configured mainly depends on the hardware parameters. The key is to match the computer according to your own needs. When looking at the hardware, you should pay attention to the following aspects:
Look at the motherboard: the motherboard is also called the motherboard, and its performance directly determines the stability of the computer.
Look at CPU: Now it is generally more than four cores, depending on its running frequency and power consumption.
Look at the memory: more than 4G. Theoretically, the larger the memory, the faster the machine will run, which must be supported by the corresponding CPU and operating system.
Look at the graphics card: now they are all independent graphics cards, with memory above 1G, depending on the bit width and frequency.
Look at the hard disk: Now the solid-state hard disk is beginning to occupy the market, the speed is ten times that of mechanical hard disk, and the budget is enough to install solid state.
Question 5: How does used computers view the real configuration of its software such as EVEREST and CPU-Z?
Software is not allowed, so take it apart and look at the hardware, or go into CMOS to see why software is not allowed.
Question 6: What do you think of the desktop configuration "My Computer" in my computer properties-> "Properties", where you can directly see the CPU manufacturer and main frequency, and click the "Hardware" tab to see the memory->; If the relevant hardware drivers have been installed, you can further view other hardware-related properties. It is recommended to obtain the windows optimization master directly, so that you can view other properties, such as sensors, in more detail.
Question 7: How to check the newly bought computer? After you get a new computer, you should check it according to the following 13 steps.

Question 8: How to check whether the computer accessories are new? It's not a renovation or anything . . . To be honest, if the computer doesn't turn on, I really can't tell if it's new. Any label outside can be faked. As long as the machine is in hand. You can see everything. You can talk to him about cash on delivery. And see if it's new.
Question 9: What do you think of the computer configuration/computer configuration list and the price? If you want to know the hardware information of the computer, it is very convenient for some software to directly check the hardware information in the computer. For example, Tencent computer housekeeper is good. Open Tencent Computer Manager and click to see the hardware information you want.
Question 10: How to assemble the computer to see if the configuration is second-hand? Download a master Lu software, mainly to check whether the hard disk and memory are brand-new and whether the reading and writing times are zero. If the CPU and graphics card are other, you can take the machine apart and see if there are any indentations on the CPU and obvious scratches on the gold finger of the graphics card. If you use the motherboard, you can check the BIOS, but generally it is not necessary to look at other hardware.
