Difficulty: Moderately Easy
Step1
Power off your computer before troubleshooting. Verify that the keyboard is securely plugged in to your computer. Try another PS/2 or USB port if your computer has more than one, or try the connections on another computer, if applicable. If the keyboard still doesn't work, then it may be defective and needs to be replaced.
Step2
Confirm that the driver software was installed correctly. Some keyboards, especially if they're wireless, require drivers in order to function properly. Follow the instructions to install any software that came with the keyboard.
Step3
Update the driver for your keyboard, if necessary. Open the control panel on your computer, check the hardware settings and then follow the commands to update the driver.
Step4
Turn the keyboard upside down to remove any dust, debris or food crumbs. These particles can also prevent the keyboard from working properly. Clean out hard-to-reach areas of the keyboard with an air compressor or a "static-safe" vacuum cleaner.
Step5
Fix the keyboard layout if the characters on screen don't match what you type. Select an input language on your computer, then choose the keyboard layout that matches that language.
