Keyboard or keys not working
Step 1: Check Physical Connections:
The first step is to ensure that the keyboard is correctly connected to your computer. If you are using a wired keyboard, check if the USB or PS/2 connector is firmly plugged into the corresponding port. For wireless keyboards, ensure that the batteries are not depleted and the wireless receiver is working correctly.
Step 2: Test on a Different Computer:
To determine whether the issue is with the keyboard or your computer, try connecting the keyboard to another computer. If it works on the other computer, the problem likely lies with your computer's settings or drivers.
Step 3: Clean the Keyboard:
Dust, debris, and spills can cause keys to become unresponsive or sticky. Turn off the computer and disconnect the keyboard. Use a can of compressed air to blow away dust and debris between the keys. If there are sticky keys due to spills, clean the affected area with a damp cloth and let it dry completely before reconnecting.
Step 4: Check for Num Lock and Scroll Lock:
If your keyboard has indicator lights for Num Lock and Scroll Lock, check if they respond when pressed. If they do not, it might indicate a hardware issue with the keyboard itself.
Step 5: Restart Your Computer:
A simple restart can often resolve temporary issues with the keyboard or the operating system. Restart your computer and check if the keyboard starts functioning correctly.
Step 6: Consider Hardware Replacement:
If none of the above steps resolves the issue and your keyboard is still unresponsive, it may be time to consider replacing the keyboard. Keyboards are relatively affordable and easy to replace.
