If your keyboard or mouse is not responding, it may be caused by loose connections, driver issues, USB port problems, or hardware faults. Follow the troubleshooting steps below to identify and fix the problem.

Step 1: Check Physical Connections

1. Ensure the keyboard or mouse USB cable is properly connected to the computer.

2. If you are using a wireless keyboard or mouse, check that the USB receiver (dongle) is properly inserted.

4. Make sure the device cable is not damaged or bent.

Step 2: Restart Your Computer

Step 4: Test with Another USB Port

1. Disconnect the keyboard or mouse.

Connect your keyboard or mouse to another computer.

• If it works on another computer, the issue may be with your system settings or drivers.
