Laptop Keyboard: If the laptop keyboard suddenly stops working, the first thing that comes to mind is that you will have to go to the service center. But every time the reason for keyboard failure is not due to hardware. In many cases, the keyboard stops responding due to minor settings or software glitches. Therefore, before going to the technician, some easy solutions should be tried.
Try restarting the system once
This method may sound simple, but many times it proves to be most effective. The keyboard driver may get stuck due to the laptop being on for a long time or an app crashing. By restarting the system, the software is loaded again in a fresh manner and the keyboard starts working again.
Check keyboard lock or accessibility settings
Sometimes keyboard lock or accessibility features like Filter Keys get activated by mistake. Due to this, some or all the keys of the keyboard stop working. Go to settings and check these options and turn them off if not needed. The problem of many users ends here.
It is also necessary to update or reinstall the driver
Problems also arise when the keyboard driver is bad or outdated. Update the keyboard driver by going to Device Manager or uninstall it once and restart the system. The system automatically reinstalls the driver so that the keyboard starts working properly.
Test with external keyboard
If you have a USB or Bluetooth keyboard, try connecting it to the laptop. If the external keyboard is working fine then it means there is a problem with the internal keyboard itself. This will give you an idea whether the problem is software or hardware.
Dust and dirt can also be the reason
If dust, dirt or food particles get stuck in the laptop keyboard, there is no response when pressing the keys. Gently shake the keyboard upside down or use compressed air. Sometimes the keyboard becomes fine again just by cleaning.
When should you go to the service center?
If the keyboard still doesn’t work after trying all the methods mentioned above, there may be a hardware malfunction. In such a situation, it would be better to show it to a technician. But by adopting these measures first, you can avoid unnecessary expenses.
