A computer keypad that doesn't work may be caused by hardware failure, driver issues, keyboard settings, or system conflicts. Hardware faults include keyboard damage or poor contact, driver problems that require checking whether the keyboard driver is installed correctly or needs to be updated, keyboard settings involving whether the Num Lock key (Num Lock) is activated, and system conflicts that may cause the keyboard to respond abnormally due to interference from other software. Keyboard settings are one of the common causes of failure. The inactivation of the Num Lock key is the most direct reason why the small keyboard cannot be used. Users can determine whether it is activated by pressing the "Num Lock" key and seeing whether the indicator light lights up.
When you encounter the problem of computer keypad not working, you should first conduct a basic check on the hardware.
Check the keyboard connection: Make sure the connector connecting the keyboard to the computer is not loose or damaged. If you are using a USB keyboard, try plugging it into a different USB port or using another computer to verify that the keyboard is working properly. Check the keyboard itself: If there is physical damage, such as a malfunctioning keypad caused by water splashing or dropping the keyboard, the keyboard may need to be replaced. Check the keyboard for any obvious signs of damage, such as detached or loose keys.Software and driver issues may also cause the keypad to malfunction.
Update drivers: Outdated or corrupt keyboard drivers can render your keypad unusable. Check if there is an available update for your keyboard driver through Device Manager, or download the latest driver from the keyboard manufacturer's official website. Check for software conflicts: Sometimes, software installed on your computer can conflict with the proper working of the keyboard. If there is a problem with the keypad after installing new software, try starting the computer in safe mode to see if the problem still exists. If the keypad can be used normally in safe mode, the problem may be caused by software conflicts.Incorrect keyboard settings are a common cause of computer keypads not working.
Num Lock key state: The Num Lock key is responsible for controlling numerical input in the keypad area. Confirming that the Num Lock indicator light is on indicates that the number lock state is activated. If you neglect to set the Num Lock key, you may mistakenly think that the keypad is damaged. Wrong keyboard layout settings: Check the keyboard layout settings in the control panel or system settings to ensure that the wrong keyboard layout is not selected, which may affect the normal use of the keypad and other keys.System-level issues may also prevent the keypad from working.
Perform system updates: Sometimes operating system bugs or bugs can cause hardware to not work properly, and performing system updates can fix these problems. Restore the system: If the keypad once worked, consider using the system restore feature to roll back to a previous state, which may resolve the issue in some cases.Virus or malware infections may interfere with the proper working of your computer, including keyboard functionality.
Perform a virus scan: Use safe and reliable anti-virus software to conduct a comprehensive scan of the system to ensure that no malicious software interferes with the normal operation of the computer. Testing in Safe Mode: Booting the computer into Safe Mode disables most non-core components, which can help determine if there is malware affecting the functionality of the keyboard.In addition to the above reasons, there are other factors that may cause the computer keypad to become unusable.
BIOS settings: In rare cases, the small keyboard function may be turned off in the BIOS settings. You can troubleshoot this problem by entering the BIOS and checking the keyboard settings. External influences: Static electricity, temperature changes, or electromagnetic interference may also temporarily affect the operation of the keyboard. In these cases, restarting the computer or disconnecting power from the keyboard for a while may help.By using the above methods to troubleshoot and solve the problem of computer keypad not working, you can usually find and solve most cases. If you still can’t resolve the issue after trying many things, it’s wise to contact a professional computer repair service for further assistance.
Why doesn't my computer keypad work?
There are many reasons why your computer keypad may not work. It may be a hardware problem or a software setting problem. Here are some common causes and solutions:
1. Is the keypad switch turned off?
Some laptops or external keyboards have a keypad switch. If your keypad doesn't work, first check to see if the switch is turned off. If so, open it and try using the keypad again.

The keypad may require specific drivers to function properly. Use Device Manager to check if an update is available for the keyboard driver. If so, it is recommended to update the driver in time.
3. Is the "Number Lock" feature enabled?
Sometimes the keypad's number keys don't work, possibly because the Num Lock feature is disabled. Look for the "Num Lock" key on your keyboard, press it and see if that fixes the problem. Additionally, some keyboards may require pressing the "Fn" key and the "Num Lock" key at the same time.
