3) How to use: After reinstalling the system, update the driver in the device manager.
Right-click the win icon to enter the device manager, or search for "Device Manager" in the search bar to enter.
If the device driver is missing, there will be a yellow exclamation mark in front of it. Double-click the icon with the yellow exclamation mark to enter the driver interface and click Update Driver.
Copy the previously backed up driver to the reinstalled computer and select Browse My Computer to find the driver.
Simply select the entire folder of the backup drive and the system will automatically search for it. Pay attention to keeping the computer fully charged. The computer will automatically restart after some drivers are installed.
Note: When loading the driver, if wifi and Bluetooth are not disabled on the BIOS page, the wifi and Bluetooth connections will be automatically restarted. If you want to ensure a network-free environment, remember to disable it.

2. Huawei Computer: Physical solution to Huawei computer’s touch screen and sound card failure after reinstalling Win11 system.
(1) Solutions that cannot be connected to the Internet
If this problem is determined to be no physical problem with the computer itself, then the failure of the touch screen and sound card is most likely caused by the driver failure after erasing and reinstalling the computer.
Therefore, as shown above, if you need to be under human supervision during the whole process and cannot connect to the Internet to solve this problem, you can check the corresponding notebook model through Huawei's official website, check whether there is a computer of the same model at your work / Huawei after-sales point, or sales store , and back up Copy the corresponding driver to the corresponding computer and load it.
Huawei computer model search:
1) Enter Huawei's official website: Driver List-Huawei Commercial Customer Service
2) Enter the serial number and model number on the back of the notebook to find the driver
(2) Solutions that can connect to the Internet
If you can connect to the Internet, the solution is to download the corresponding computer manager from Huawei's official website and let the computer manager connect to the Internet to solve the driver problem. (Only a small part of the drivers are provided on Huawei's official website. If you completely erase the computer and reinstall the system, and only load the sound card, it will most likely not have any effect.)
2. One-click installation
Baidu search: Just reinstall the win11 system. There is a system home that you can check out for one-click installation. They are basically non-toxic.
After right-clicking to extract it to the folder, just run the one-click installation .exe. This process can be carried out without being connected to the Internet. It is best not to connect to the Internet, because this one-click installation package comes bundled with many other 360, wps and other software. If you do not need it, just delete and uninstall it from the control panel.
