How Do You Troubleshoot Keyboard Problems?

Troubleshoot keyboard problems by checking underneath the keys for crumbs or other types of debris, checking the computer’s drivers to ensure they are up-to-date, testing the keyboard with different programs, and restarting the computer. Some wireless or wired external keyboards may also have issues with the connecting ports, wireless signal or the batteries.

One common source of an unresponsive keyboard is a physical blockage underneath the keys, which prevents it from depressing fully and thus registering the appropriate keystroke. Some keyboards may have enough space under the keys to remove debris with a cotton swab or small brush, while others with tight casings around the keys may require the use of compressed air. Another common cause of keyboard issues is an outdated or corrupted driver, which is the software that tells the computer how to communicate with the keyboard. Check the computer’s drivers to ensure they are up-to-date through the driver-management program or by downloading the latest version from the manufacturer’s website.

In some cases, the problem may only appear in a specific program. In these cases, check multiple programs to isolate the issue and research the keyboard and driver options of the offending software. Wireless keyboards also frequently experience issues due to connectivity issues, such as the Bluetooth reception being off on the computer or the wireless dongle disconnecting. Some wired keyboards may also need driver updates or experience issues with the USB port.
