  • If the device shows errors or warnings, try updating the driver by selecting **Update driver**. Choose the automatic search option to let Windows find the latest version.
  • For macOS, keyboard drivers are integrated into the operating system, so ensure your system is updated via **System Preferences > Software Update**.

If updating the driver does not resolve the issue, consider uninstalling the keyboard device in Device Manager and restarting your laptop. This forces the system to reinstall the driver, which can correct corrupted files or settings.

Cleaning and Physical Inspection

Physical issues such as debris, dust, or spills can impair keyboard performance. Carefully inspecting and cleaning your keyboard can sometimes restore functionality without the need for repairs.

To clean your keyboard effectively:

  • Power off your laptop and disconnect any external power sources.
  • Use compressed air to blow away dust and particles from between the keys.
  • For sticky or unresponsive keys, gently clean around the keycaps using a cotton swab dipped in isopropyl alcohol (at least 70% concentration).
  • Avoid excessive moisture and do not remove keycaps unless your laptop manual specifically allows it.

If a liquid spill has occurred, immediate action is crucial:

  • Turn off the laptop and disconnect power.
  • Remove the battery if possible.
  • Tilt the laptop to drain the liquid.
  • Allow the device to dry completely for at least 24 hours before attempting to power it on.

In cases where cleaning does not help, inspecting the keyboard for physical damage such as broken key mechanisms or loose ribbon cables may be necessary. Such issues often require professional repair or replacement.

Using External Keyboards and Diagnostic Tools

To isolate the problem, testing with an external keyboard can determine whether the issue lies with the laptop hardware or the software.

Connect a USB or Bluetooth external keyboard and check if it responds correctly. If the external keyboard works perfectly, this indicates a hardware issue with your laptop keyboard. If it also fails, the problem is likely related to your operating system or settings.

Many laptops come with built-in diagnostic tools that can help identify keyboard problems:
