Many different reasons can make the keyboard to underperform or even completely stop functioning. These causes are as a result of either human-generated errors or computer-based software issues altogether. However, with the correct guide, you can troubleshoot and solve the malfunction.
Remember that some of the malfunctions can be caused by hardware failure while other reasons can arise from the Windows 10 software issues.
The main reason that causes the keyboard to malfunction in Windows 10 is the driver incompatibility issues. Other reasons like damaged cable, broken button connectors and disabled keyboard also play a significant role.
In this article, we will look at all the reasons (both hardware and software) that cause keyboard malfunction in Windows 10 and all the ways of troubleshooting the issues.
Common causes of keyboard malfunctions
There are four common causes of keyboard malfunctions.
1. Hardware issues
- Faulty connection cables
- Broken keys/button plugs
a) Faulty cable connectors
A faulty cable connector is a common hardware-related issue that causes a keyboard to malfunction. You should first check the connector before considering other troubleshooting methods.
Steps to follow.
- Using the correct tools, carefully unscrew your computer using a step-by-step guide.
- Access the cable connector (it is usually a wide cable with white or black connector plugs)
- If the plugs are disconnected, you should manually reconnect them.
- Note that when operating with the keyboard connectors, you should be keen not to damage the cables.
- If the connectors are securely in place, you should clean the plugs or any other joining pieces with a dry cloth/cleaning solution and check if the keyboard works after rebooting the computer. DO NOT screw back the computer before confirming whether the keyboard is working appropriately.
Quick Fix: Before unscrewing the computer, you can restart it before detaching the keyboard and check if the issue has been resolved.
b) Broken buttons/connector plugs
Broken buttons and plugs are also common issues that cause keyboard malfunction. Hence, to check whether that is the issue, you should physically check the keyboard keys by following the steps below.
- Unscrew the computer
- Detach the keyboard from the computer’s motherboard
- Physically check underneath the keyboard to see whether there are broken keys
- If there are broken buttons, you should replace then immediately to help resolve the issue.
2. Software issues
- Driver incompatibility
- Locked or disabled keyboard
a) Driver incompatibility or Windows 10 corrupt updates
All keyboards are configured to match with the BIOS settings automatically. However, when there is a driver incompatibility issue that arises from different reasons, the keyboard will malfunction or behave unusually.
There are two procedures involved to solve this issue – the manual update and automatic driver update.
You should follow the steps below.
- Right-click the Start button
- Go to Device Manager
- Check and see whether there is a yellow exclamation mark on the keyboard command.
- If there is a yellow exclamation mark, right-click it.
- Alternatively, you can click the keyboard command to expand it. Right-click the Standard PS/2 Keyboard
- You can then either “update the driver” or even “scan for hardware changes” and click OK.
Alternatively, you can go via the manual update method to resolve the malfunction issue.
- Visit the official manufacturer’s website.
- Check for the recent keyboard driver.
- Follow all the required steps and install the update.
b) Locked or disabled keyboard
This situation often occurs unintentionally. You can accidentally lock your keyboard by pressing the Ctrl+Alt+L keys to turn ON the filter keys.
To unlock the keyboard, you need to press the SHIFT key for approximately 5 seconds (or longer in some cases).
Testing the keyboard after troubleshooting
You can test the keyboard by following a few steps to confirm that it is working precisely.
There are three ways of testing the keyboard.
- Online keyboard testing
- Testing via the control panel
- Testing using a downloadable program
Here are the steps to follow while using the control panel.
- Click the Start button.
- Navigate to the control panel then system
- Open Device Manager
- Open the browser
- Type “Keyboard test.”
- A list of related links should appear after clicking the search button.
- Choose any working link and test the keyboard.
- If the keys are configured correctly, the online tester will notify you.
Using a downloadable program is also another alternative for testing the keyboard or webcam on Windows 10. The advantage of using a downloadable program is the advanced features and automatic functionalities available.
Using the downloadable program.
Once you have downloaded the application, you should install it and precisely follow all the required steps.
Here are three of the best keyboard software testers to pick.
- Pass Mark Keyboard Test
- Aqua Key Test
- Kb Tester
Note that testing the keyboard on the word processor or any other typing-enabled application on Windows 10 will not tell if the keyboard has additional technical issues.
Adjusting keyboard settings
Incorrect Windows 10 keyboard configurations can also cause the keyboard to stop working. Thus, by following the steps below, you can solve the issue.
- Click the Action Center icon (usually located at the bottom right corner of the computer’s screen)
- Navigate to All Settings
