IV. Troubleshooting Software Issues
A. Update or Reinstall Keyboard Drivers
Press the Windows key + X and select “Device Manager” from the menu.
Locate and expand the “Keyboards” category.
Right-click on your Dell keyboard and select “Update driver.”
Choose “Search automatically for updated driver software” and follow the on-screen instructions.
If updating the driver does not resolve the issue, try uninstalling the keyboard driver by right-clicking on it and selecting “Uninstall device.”
Restart your computer, and Windows will automatically reinstall the keyboard driver.
B. Check Keyboard Settings
Press the Windows key + I to open the Settings app.
Click on “Time & language.”
Select “Keyboard” from the left panel.
Ensure that the correct keyboard layout is selected for your Dell keyboard.
If you are experiencing issues with specific keys, check if any keyboard shortcuts or hotkeys are interfering with their functionality.
C. Boot into Safe Mode
Booting your computer into Safe Mode can help determine if conflicting software or malware is causing your keyboard to malfunction.
Press the Windows key + R to open the Run dialog box.
Type “msconfig” and hit Enter to open the System Configuration utility.
Click on the “Boot” tab and check the “Safe boot” box.
Choose “Minimal” and click “Apply” followed by “OK.”
Restart your computer to boot into Safe Mode.
Test your keyboard in Safe
Mode.
If your keyboard works correctly in Safe Mode, the issue may be related to conflicting software or malware.
To identify and resolve the conflict, disable non-essential startup programs and services one by one and restart your computer in normal mode each time to see if the keyboard issue persists.
To disable startup programs and services, press the Windows key + R, type “msconfig” and hit Enter to open the System Configuration utility.
Click on the “Services” tab, check the “Hide all Microsoft services” box, and click “Disable all.”
Next, click on the “Startup” tab and click “Open Task Manager.”
In the Task Manager, disable non-essential startup programs one by one by right-clicking on them and selecting “Disable.”
Restart your computer in normal mode and test your keyboard after disabling each program or service until the issue is resolved.
If you identify the conflicting software, either remove it or update it to a compatible version.

Click on “Update & Security.”
Select “Windows Update” from the left pane.

Type “rstrui” and hit Enter to open the System Restore utility.
Follow the on-screen instructions to choose a restore point and complete the System Restore process.
Restart your computer and test your keyboard.

If all other troubleshooting steps have failed, you may need to reset your PC to resolve the keyboard issue.
Press the Windows key + I to open the Settings app.
Click on “Update & Security.”
Select “Recovery” from the left pane.
