How to test the computer when you buy it, and how to test the computer after it is assembled?

When buying a computer, testing is one of the essential links. Here are a few steps to test the machine:

1.Boot check: Check whether the system starts normally and whether there is any abnormal prompt after booting.

2.Touch screen: For PCs with touch screens, you can test the response of the touch screen to check if it is smooth and stable.

3.Operation shortcuts: Test some common actions, such as keyboard speed

Steps of computer test method:

1. View hardware information: right-click "My Computer", select "Properties", click the "Hardware" tab, click "Device Manager" in the Device Manager bar, and view the various hardware windows installed on the computer that appear.

2. Check the model and frequency of the CPU: click "Start" and "Run" to enter "DXDIAG", and then press Enter, it will open a "Direx Diagnostic Tool", where the model and frequency of the CPU will be displayed in the "System Information" line of the "Handling Instrument" of the draft.

3. Check the memory size branch: right-click "My Computer", select the "Properties" item, and the memory size will be displayed in the "General" column.

4. Check the size of the hard disk: Open "My Computer", then check the properties of each hard disk drive separately, and add their respective capacity to get the capacity of the entire hard disk.

5. Check the size of the video memory: Click the desktop with the right mouse button, and then select "Properties" in the pop-up menu, and then select "Settings, Advanced, Adapters", here you can view the size of the video memory.

After the computer is assembled, in order to ensure that there is no problem with the hardware, it is necessary to conduct a test machine on the macro.

Here are the test steps:

1.Check whether the hardware components are installed correctly, especially whether the CPU and memory modules are inserted correctly, and whether the power connection is normal.

2.Plug in your monitor, keyboard, mouse, and power cord.

3.Depending on your operating system, select the appropriate display output on the motherboard to connect to your monitor.

4.Turn on the power and observe whether the electric fan is running normally.

5.If you have a disc or USB stick, plug it into your computer.

6.Enter the BIOS or UEFI through the keyboard or mouse, and check whether the hardware device is correctly recognized, and check whether the CPU frequency, temperature, and other information are normal.

8.Finally install your operating system and make sure it will boot up and running smoothly.

If you encounter a problem, you can eliminate the test situation one by one, find the problem, and fix it. Before attempting anything, make sure that you have backed up your important data to avoid losing yourself by mistake.

When buying a computer, verifying the SN code is very necessary for Shiyuan.

The SN code is located on the outer packaging of the notebook, the back of the notebook, and the battery of the notebook.

After the inspection is completed, the diggers will help you install the system, and after debugging the system, ask the staff to install a hardware detection software (everest, Master Lu, etc.) for you, and check whether the configuration of your machine is the same as the configuration sheet on the spot.

It's easy to check parallel goods, just observe and see how the notebook looks. Look at the letters on the notebook keyboard, the warranty card generally has the authenticity of the electronic talk check on the phone, just do it.

However, Lenovo's credibility is still very good.

If it is 4099 before the supplement, this machine is very cost-effective, and you can start it. If it's made up,Then the money to make up is to make Gome earn,Three Kingdoms month ago, I bought this configuration of the machine is 4050 with an official invoice,It's Lenovo Z460,Consider it yourself,In our case, let them earn,It's better to buy it cheaper in a store!

Check the machine, I feel that you should be the next Master Lu, with Master Lu can check the hard disk use time, configuration and manufacturer and other information.

Another note: to install it in advance on the USB flash drive, and click "Performance Test" to install the performance test software, and look at the hard disk usage time, battery wear and other information in the "Hardware Health". In addition, test the graphics card in the "performance test", look at the fluency and other information, this can only be a reference, Master Lu is not too good now, can only be used as a reference, but the information in the hardware health can be seen, in addition, look at the hardware information in the hardware overview, and compare it with the packing list.

The most important point is to look at the serial number, on the chassis, on the back cover of the computer, BIOS (press F2 to enter at the moment of boot, you can see the serial number) The three serial numbers are the same, under normal circumstances, as long as the serial number is matched, it will be fine. When choosing a machine, we must see whether the box has been opened, if it has been opened, we must let him change, there is no negotiation, there are many ideas for profiteers, we can't prevent it, only this.

It is recommended to try it with Master Lu, I tried it and thought it worked well.

There is also how the keyboard and mouse feel, after all, you want to use it.
