Question:

“Dear expert, I am encountering a recurring issue with my keyboard where it inadvertently types numbers when I am trying to input letters. This problem has arisen before, and I was able to resolve it by performing a certain action on my laptop, but I cannot recall the specific solution. Despite searching online and attempting various fixes, including uninstalling and reinstalling the keyboard drivers twice and rebooting my computer multiple times, the issue persists. I assure you there has been no spillage on my PC, nor do I consume food near it. I am at a loss for what further steps to take, as this problem hinders my ability to play games like Minecraft or compose essays. It is incredibly frustrating. For instance, when I press the key for ‘2’, it registers as ‘S’ and vice versa. Could you please advise me on how to rectify this malfunction?”

Answer:

Dear user,

I understand the frustration that comes with a malfunctioning keyboard, especially when it impedes your daily activities such as gaming and writing. The issue you’re describing sounds like a classic case of keyboard ghosting or a malfunctioning keyboard matrix. Here’s a step-by-step guide to help you troubleshoot and hopefully resolve the problem:

Sometimes, debris or dust can cause keys to register incorrectly. Turn off your laptop, unplug it, and try cleaning around the affected keys with compressed air.

Step 2: Check for Hardware Issues

Inspect the keyboard for any visible signs of damage. If your laptop has a removable keyboard, gently take it out and reseat it, ensuring all connections are secure.

Step 3: Update or Rollback Drivers

Since reinstalling the drivers didn’t work, try updating them to the latest version available. Alternatively, if the issue started after an update, consider rolling back to a previous driver version.

Step 4: Adjust Keyboard Settings

Check your keyboard settings in the control panel. Ensure that the correct language and layout settings are selected, and look for any options that might be causing the keys to behave incorrectly.

Step 5: External Keyboard Test

Connect an external keyboard to your laptop. If the external keyboard works fine, the issue is likely with the laptop’s hardware.

Step 6: System Restore

If you recall the issue being fixed previously, a system restore to a point when the keyboard was functioning correctly might solve the problem.

Step 7: Professional Help

If none of the above steps work, it might be time to seek professional help. A technician can diagnose whether the problem is with the keyboard itself or with the motherboard’s connections.

Remember, if your laptop is still under warranty, contact the manufacturer before opening up the device or making any significant changes.

I hope one of these steps leads to a resolution. Good luck!
