Solution: Find the driver disk for installation, which is in the correct status during installation.

 

 

 

 

2. the laptop keyboard may not be used as a USB or keyboard set in the BIOS. It is accidentally disabled.

3. Recently? Use of USB disabled with illegal software

 

Solution: click "Start, Run", enter the "Regedit" command in the run dialog box, press enter, and the Registry Editor is displayed. Expand "HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ usbstor" in sequence ", find the "Start" Key, double-click it, change its value to "2", click "OK", and restart the system "start", which is the work switch of the USB device, by default, "3" indicates manual, "2" indicates automatic, and "4" indicates disabled.

 

 

 

 

 

 

 

4. the keyboard of the laptop is the same as that of the USB. The EC chip is broken.

 

Solution: Find a chip-level service. You can remove the keyboard of the notebook and try it with a USB keyboard. I think it may also be caused by a short circuit of the notebook keyboard that makes those keys unusable.
