Hello Shibaagro,

Thank you for posting your concern,

Troubleshooting Keyboard Issues on HP EliteBook 840 G10 Notebook PC

If you're experiencing issues with the "G," "H," and "Backspace" keys not working consistently on your HP EliteBook 840 14 inch G10 Notebook PC, here are some steps you can take to troubleshoot and resolve the issue:

1. Check for Debris:

   • Ensure there is no debris or dirt under the keys. You can gently clean the keyboard with compressed air.

2. Update Keyboard Driver:

   • Go to the HP Support website, enter your serial number or product name, and check for any available driver updates, particularly for the keyboard.

3. BIOS Update:

   • Ensure your BIOS is up to date. Updates can fix potential bugs affecting keyboard functionality. Follow this guide to find and install the latest BIOS update.

4. Test Keyboard in Different Environments:

   • Boot into the BIOS or a different operating system (if possible) to see if the problem persists outside of Windows. This can help determine if it's a hardware or software issue.

5. Hardware Diagnostics:

   • Run HP’s hardware diagnostics tool to check if there are any hardware issues. This tool can typically be accessed by pressing the F2 key during startup.

6. External Keyboard Test:

   • Connect an external keyboard to verify if the issue is isolated to the built-in keyboard.

If the problem persists after trying these steps, it might indicate a hardware issue, and you should consider contacting HP Support or visiting an authorized service center for further assistance.
