There can be a number of reasons why a mouse or keyboard is not working correctly. The following are some of the most common issues that may arise and how to troubleshoot them:
1. Check Your USB Ports: Many mouse and keyboard problems can be due to faulty connections within the USB ports on your computer. Make sure all cables are securely connected, and if possible, try plugging in the device into a different port. Also, check to make sure your ports aren’t damaged.
2. Check Your Drivers: If your mouse or keyboard isn’t working, then make sure you have the latest drivers installed. You can find your driver downloads on the manufacturer’s website.
3. Use the Correct Settings: Your mouse and keyboard may not be responding correctly because you’re using the wrong settings. Go into the device manager, and check to see if the settings are optimized for the particular device you’re using.
4. Rule Out Hardware Issues: A hardware issue can also cause the mouse and keyboard to malfunction. To check for any hardware issues, you can open up the device and clean any debris or dust out of the inside.
5. Swap Out Parts: If the issue persists, try swapping out parts. This could be swapping the mouse and keyboard, switching out the cables, or replacing the batteries.
6. Reset the Device: Finally, try to reset the mouse or keyboard. This can be accomplished by pressing a reset button that may be located on the bottom of the device.
If none of these solutions work, then it’s likely that the mouse or keyboard is defective and needs to be replaced.
