Fix 1: Confirm Shortcut Keys Don’t Disable Function Keys<\/h2>\n\n\n\n

Keyboards with an Fn key allow two sets of actions on the function keys. For instance, the F8 key can have a secondary action of music playbacks apart from the default one. But sometimes, the Fn key combination may not work, and you must check if it’s locked.<\/p>\n\n\n\n

Step 1: <\/b>Check if any of the keys have a lock icon<\/strong> (usually available with the Esc key).<\/p>\n\n\n\n

Step 2:<\/strong> If yes, long-press the Esc key<\/strong> to lock or unlock the key and check if the Fn keys are working as expected.<\/p>\n\n\n\n

Step 3: <\/strong>If there are no keys with a lock icon, some keyboards allow users to disable or enable them by long pressing<\/strong> the Fn key. <\/p>\n\n\n\n

If none work, you must go through the Keyboard manual and check how to do it or if the feature is available. <\/p>\n\n\n\n

Fix 2: Enable Function Key Through the BIOS or UEFI Settings<\/h2>\n\n\n\n

An update or error in the BIOS settings can affect the workings of the function keys. To fix disabled keys<\/a>, visit the BIOS settings and enable the functions. Here’s how to do it.<\/p>\n\n\n\n

Step 1:<\/strong> Restart and boot into your PC UEFI or BIOS using the Del<\/strong> or F2 <\/strong>key.<\/p>\n\n\n\n

Step 2: <\/strong>Go to Advanced options<\/strong> or the section that allows you to change keyboard behavior. <\/p>\n\n\n\n

Step 3: <\/strong>Locate Function Key Behavior<\/strong> and click on it. Select the Function key<\/strong> as default.<\/p>\n\n\n\n

\"BIOS<\/figure>\n\n\n\n

Step 4:<\/strong> Save the changes and restart your computer. Confirm if the function keys now work correctly.<\/p>\n\n\n\n

Fix 3: Activate Human Interface Device Services<\/h2>\n\n\n\n

Another reason the keyboard function may stop is if the HID services have stopped. To enable the service, visit the Windows Service’s controls.<\/p>\n\n\n\n

Step 1:<\/b> Type services.msc<\/em><\/strong> in the Run <\/strong>prompt (Win + R) and press Enter.<\/strong><\/p>\n\n\n\n

Step 2:<\/strong> Locate the Human Interface Device<\/strong> services and double-click<\/strong> to open its property window. <\/p>\n\n\n\n

Step 3:<\/strong> Under the General<\/strong> tab, click on Start<\/strong> next to the Service <\/strong>section<\/p>\n\n\n\n

Step 4:<\/strong> Move back up, locate the Startup type<\/strong>, and set it to Automatic<\/strong>.<\/p>\n\n\n\n

\"HID<\/figure>\n\n\n\n

Step 5:<\/strong> Click Apply<\/strong>, then OK <\/strong>to apply the changes.<\/p>\n\n\n\n

Step 6:<\/strong> Restart your PC and confirm the function keys work correctly.<\/p>\n\n\n\n

FAQs<\/h2>\n\n\n\n

1. Are Fn Keys on the Keyboard Dependent on the Human Interface Device Services on Windows?<\/h3>\n\n\n\n

The HID service manages communication between Windows and input devices. Fn keys on keyboards activate multimedia functions like volume control or brightness adjustment<\/a>, i.e., translate the Fn key combination into the appropriate command.<\/p>\n\n\n\n

2. HID Service Is Set to Manual, But the Fn Keys Are Working. Why?<\/h3>\n\n\n\n

Fn keys may still work even if the HID service is set to Manual<\/strong> for reasons such as BIOS activation, third-party program managing the critical responses, or the driver pre-loading the OEM combinations. <\/p>\n\n\t\t\t
