What should I do first if my number pad is not working?
If your number pad is not working, start by checking if the Num Lock key is enabled. This key toggles the functionality of the number pad. If the Num Lock is off, it may cause the number pad to behave differently, such as requiring the use of the Shift or Fn key to type numbers. Press the Num Lock key once and see if it resolves the issue.
If enabling Num Lock does not fix the problem, try rebooting your computer. Sometimes, temporary glitches can cause peripherals to malfunction. Restarting your computer can refresh the system and potentially resolve any underlying issues with the keyboard. After the reboot, test the number pad again to see if it works.
What if the Num Lock key is enabled but my number pad still doesn’t work?
If the Num Lock key is enabled and your number pad is still unresponsive, check to see if there are any physical obstructions or debris under the keys. Dust and particles can sometimes inhibit the number pad’s functionality. Gently clean the area using compressed air or a soft brush to remove any debris that might be affecting the keys.
Next, consider whether the issue might be software-related. Update your keyboard driver to ensure you have the latest version installed. Go to the Device Manager on your computer, find the keyboard section, and check for any available driver updates. An outdated or corrupted driver can prevent the number pad from functioning correctly.

To proceed with a clean boot, follow the specific steps for your operating system to disable unnecessary startup applications.
If the number pad continues to malfunction in a clean boot environment, consider checking for malware or viruses that could be affecting your keyboard’s performance. Running a full system scan with up-to-date antivirus software could detect and eliminate any malicious software that might be causing the issue. Additionally, review any recently installed software or updates that could coincide with the keyboard issues and consider uninstalling them to see if it resolves the malfunction.
What operating system settings should I check if my number pad is not working?
If your number pad is not functioning properly, you may want to check your operating system’s keyboard settings. For Windows users, head to the Control Panel and navigate to the “Ease of Access” settings. Check if “Turn on Mouse Keys” is enabled, as this feature allows you to control the mouse pointer using the number pad, which can lead to confusion if you’re trying to use the number pad for input instead.
For Mac users, go to “System Preferences” and then “Keyboard.” Ensure that the “Key Repeat” and “Delay Until Repeat” settings are set to reasonable values. Additionally, check for any keyboard shortcuts that may have been inadvertently assigned to the number pad keys that could affect their functionality. Adjusting these settings may help in restoring normal function to your number pad.
