HP 350 Compact Wireless Keyboard – F10 and Down Arrow Keys Not Working

[saptaswa99]

I am experiencing an issue with my HP 350 Compact Wireless Keyboard.
Device: HP 350 Compact Wireless Keyboard

The F10 key and the Down Arrow key are not functioning, while the other keys work as expected. The issue persists across multiple applications (including Visual Studio and Notepad).

Troubleshooting performed:

• Reconnected the keyboard.
• Replaced/rechecked the batteries.
• Tested in different applications.
• Restarted the PC.
• Verified that the issue is with the physical keyboard.

Hi @saptaswa99, Welcome to the HP Support Community.
 

Thank you for providing such a detailed description of the issue and the troubleshooting you've already completed. Since you've confirmed that the F10 key and the Down Arrow key on your HP 350 Compact Wireless Keyboard do not work, while all other keys function normally, we can narrow down the possible causes.
 

The F10 and Down Arrow keys are unresponsive across multiple applications, including Visual Studio and Notepad, even after reconnecting the keyboard, replacing the batteries, and restarting the computer.
 

When only a small number of keys stop responding while the rest of the keyboard functions normally, the issue is typically related to one of the following:

• A keyboard function mode or Fn lock setting.
• A driver or keyboard configuration issue.
• A hardware fault affecting the individual keys.

Since you've already verified the behavior in multiple applications, the problem is less likely to be application-specific.
 

1. Verify Function Key Behavior

On compact keyboards, some function keys may perform secondary actions unless the Fn key is used.

1. Check whether the F10 key works when pressed together with the Fn key.
2. Try pressing Fn + Esc to toggle Fn Lock, then test the F10 key again.

Why this helps:
Some compact keyboards allow switching between multimedia functions and standard function keys, which can affect how the F1–F12 keys respond.

2. Confirm the Keyboard Layout

1. Inspect the keycaps for any secondary symbols printed on or near the F10 or Down Arrow keys.
2. If alternative functions are shown, test them using the Fn key combination.
    

Why this helps:
Compact keyboards often combine multiple functions on the same keys to reduce the keyboard size.

3. Update or Reinstall the Keyboard Driver

1. Open Device Manager.
2. Expand Keyboards.
3. Right-click your HP keyboard and select Update driver.
4. If the issue persists, select Uninstall device, then restart the computer to allow Windows to reinstall the default driver.

Why this helps:
Reinstalling the driver refreshes the communication between Windows and the keyboard and can resolve corrupted driver configurations.

4. Check Windows Keyboard Settings

1. Open Settings > Accessibility > Keyboard.
2. Verify that features such as Sticky Keys, Filter Keys, or other accessibility options are disabled unless intentionally enabled.

Why this helps:
Certain keyboard accessibility settings can affect how keystrokes are interpreted.

5. Verify HP Software (If installed)

1. If your keyboard uses HP software or a keyboard management utility, ensure it is installed and updated.

Why this helps:
HP software can manage keyboard behavior and function key assignments. Updating it helps ensure compatibility with the latest Windows updates.

6. Check BIOS/UEFI Function Key Settings (If Applicable)

1. Some HP systems allow the default behavior of the function keys to be changed in the BIOS.
2. Restart the computer, enter the BIOS setup, and look for any Action Keys Mode or Function Key Behavior settings.
    

Why this helps:
Changing the function key mode can restore expected F-key functionality if the behavior was modified.
 

If the issue is caused by keyboard configuration or software, these steps should restore normal operation of the F10 and Down Arrow keys.

If both keys remain non-functional after completing these steps and especially if they do not work on another computer, it is likely that the keyboard has developed a hardware fault affecting those specific keys.
 

To help determine whether this is a software or hardware issue, could you please confirm the following?

• Have you tested the HP 350 Compact Wireless Keyboard on a different computer, and do the F10 and Down Arrow keys behave the same way?
• Are you using the keyboard with the included USB wireless receiver or via Bluetooth?

Have a great day!
