1) Check the Physical Connections:

Ensure that all physical connections are secure as this is the first and simplest step:

a. For USB devices, unplug them from your computer and replug them into different ports.

c. To rule out any possible hub issues when utilizing a USB hub, try connecting the devices directly to your computer.

2) Reboot Your Computer:

Technical issues can frequently be fixed with a simple restart. Save your work, then restart your computer properly. The input devices may occasionally stop working due to transient software problems.

3) Use On-Screen Keyboard and Mouse:

You can use the on-screen keyboard and mouse accessibility features if your real keyboard and mouse are still not functional.

a. In Windows, select “Settings” > “Ease of Access” > “Keyboard” and enable “On-Screen Keyboard.”
a. Select “Mouse” under the same “Ease of Access” options for the on-screen mouse, then turn on “Mouse Keys.”

4) Check Device Manager:

To identify and fix hardware-related problems, Device Manager is a helpful tool. This is how you can get to it:

a. Right-click the “Start” icon and choose “Device Manager.”
b. Check out the “Keyboards” and “Mice and other pointing devices” categories.
c. Driver issues are shown by a red “X” or a yellow exclamation point next to your keyboard or mouse, respectively.

Misconfigured input devices can frequently be caused by outdated or corrupt drivers. Try these things:

9) Use System File Checker (SFC) and DISM:

System File Checker (SFC) and Deployment Imaging Servicing and Management (DISM) are built-in Windows utilities for scanning and repairing corrupted system files that may be causing input device issues.

  1. Open Command Prompt as an administrator.
  2. Run the command sfc /scannow and let it scan for and repair system files.
  3. After that, run the command DISM /Online /Cleanup-Image /RestoreHealth to repair the Windows image using online resources.
