Consider replacing batteries with new ones to eliminate a low battery issue.
If using a Bluetooth keyboard, confirm that Bluetooth is enabled on your computer. Check the Bluetooth settings to see if the keyboard is paired and connected. Sometimes, unpairing and re-pairing the keyboard can resolve connection problems. Also, make sure no other devices are interfering with the Bluetooth signal.
How can I restart my computer using only the mouse if my keyboard is disabled?
If your keyboard is completely unresponsive, you can utilize the on-screen keyboard provided by your operating system to initiate a restart. In Windows, access the on-screen keyboard by clicking the Start button, then navigating to Settings > Ease of Access > Keyboard, and toggling the “Use the On-Screen Keyboard” option to “On.” Once activated, you can use the on-screen keyboard to click the Start button, then the Power icon, and finally select “Restart.”
On macOS, you can enable the Accessibility Keyboard through System Preferences > Accessibility > Keyboard > Enable Accessibility Keyboard. This will bring up an on-screen keyboard that allows you to navigate to the Apple menu and select “Restart.” Be patient as navigating with the mouse only can be slower.
What are keyboard drivers and how do I update them?
Keyboard drivers are software programs that enable your operating system to communicate with your keyboard. They translate your keystrokes into signals that the computer can understand. Outdated or corrupted drivers can cause keyboard malfunctions, including complete failure to respond. Updating to the latest drivers is a common troubleshooting step.
To update your keyboard drivers in Windows, open Device Manager (search for it in the Start menu). Expand the “Keyboards” category, right-click on your keyboard, and select “Update driver.” Choose “Search automatically for drivers” to allow Windows to find and install the latest available drivers.

Replace the batteries with fresh ones to rule out this cause. Check the connection between the keyboard and the receiver or Bluetooth. The receiver should be securely plugged into the computer. Verify that Bluetooth is enabled if it’s a Bluetooth keyboard.
If the issue persists, try re-pairing the keyboard with your computer. Put the keyboard into pairing mode (refer to your keyboard’s manual for instructions) and search for it in your computer’s Bluetooth settings. Remove the existing pairing and create a new one. Interference from other wireless devices can also disrupt the signal, so try moving away from potential sources of interference.
How can I test if my keyboard itself is broken?
The most reliable way to test if your keyboard has a hardware issue is to try it on another computer. If the keyboard fails to function properly on a different computer, it is likely a hardware problem with the keyboard itself. You can also try a different keyboard on your current computer to check if the issue is with the computer or the keyboard.
Another method is to use an online keyboard testing website. These websites allow you to press keys on your keyboard and see if they are being registered by the website. If certain keys consistently fail to register, it suggests a hardware fault within those specific keys or the keyboard’s internal circuitry. This, combined with testing on another machine, can solidify the conclusion of a hardware failure.
What are Filter Keys and how can they disable my keyboard?
Filter Keys is an accessibility feature designed to ignore brief or repeated keystrokes, intended for users with hand tremors or similar difficulties. When enabled, it can make it seem like the keyboard is not responding or is extremely slow to register key presses. It essentially filters out what the system perceives as accidental or unintended keystrokes.
To disable Filter Keys in Windows, go to Settings > Ease of Access > Keyboard. Ensure the “Use Filter Keys” toggle is set to “Off.” Similarly, in macOS, go to System Preferences > Accessibility > Keyboard and then click on the “Hardware” tab. Make sure the “Slow Keys” option is not selected. Accidentally enabling this feature can drastically affect keyboard performance and make it appear as if the keyboard is malfunctioning.
