How to Turn off the Fn key on an HP Laptop?

Do you find yourself constantly hitting Fn instead of F1 through F12 when trying to use function keys on your HP laptop? Having to hold the Fn key to use these essential keys can get annoying. Luckily, there is a simple setting change to disable the Fn key on HP laptops.

The Fn key on laptops serves an important purpose by providing quick access to special functions like media playback controls, screen brightness, volume, and more. However, this also means you need to hold Fn to access the standard F1-F12 function keys on many compact laptop keyboards.

If you’d prefer to use these keys normally without holding Fn, HP laptops provide the option to turn off the Fn key through a BIOS setting change.

In this post, I’ll explain what the Fn key does, why you may want to disable it, and walk through the straightforward steps to turn off the Fn key on HP laptops so you can use the function keys as you normally would on a desktop keyboard.

With just a quick BIOS tweak, you can improve your workflow and use of the function keys.

What Does the Fn Key Do on Laptops?

The Fn key is found on most laptops and serves an important function. While a desktop keyboard has dedicated keys for controls like volume, brightness, play/pause, etc., laptops lack the physical space for so many extra keys.

This is where the Fn key comes in – it acts as a modifier that gives access to special functions by holding it and pressing a function key like F2 for screen brightness. So on a compact laptop keyboard, the Fn key essentially enables an extra layer of controls.

According to HP, holding the Fn key also allows you to use the standard F1 through F12 function keys. Without it, tapping F2 would increase your laptop’s screen brightness for example. Having to use Fn to type F2 or other function keys can disrupt workflow for some users.

Why Would I Want to Turn Off Fn Key on My HP Laptop?

Here are more detailed explanations for why you may want to turn off the Fn key on an HP laptop:

1.    Avoid accidentally activating special functions when trying to use F keys

Pressing F1-F12 keys triggers special functions like brightness or volume instead of standard functions like refresh or save, which can be disruptive. Turning off Fn prevents accidentally triggering media keys when you intend to use a function key shortcut.

2.    Eliminate the need to hold Fn when pressing F1 through F12

Having to hold down Fn and press F5 to refresh is less efficient than just pressing F5 by itself. Disabling the Fn key eliminates the need to use two hands or shift your grip, allowing seamless use of function keys.

3.    Prefer function keys to work as expected without modifier

Many users are accustomed to function keys working normally on desktop keyboards. Needing to hold Fn on a laptop is an unfamiliar extra step they’d rather avoid. Turning off Fn provides consistency.

4.    Find constant use of Fn tedious for certain workflows

Some applications or workflows rely heavily on function keys like F5. Having to hold Fn repeatedly can cause hand fatigue over extended usage. Disabling Fn streamlines these use cases.

5.    Personal preference for improved typing ergonomics

Based on hand size and typing position, some users find frequently holding Fn puts strain on their hands. Turning it off creates a more ergonomic typing experience and prevents muscle cramps or fatigue.

In summary, disabling Fn improves efficiency, prevents mis-presses, reduces hand strain for frequent function key users, and aligns with user familiarity – giving a better overall experience.

How to Turn Off Fn Key on HP Laptops?

The process to disable the Fn key on HP laptops is simple and straightforward through the BIOS settings:

  1. Restart your HP laptop and as soon as you see the HP logo, rapidly tap the F10 key to enter BIOS setup.
  2. Using the arrow keys, go to the “System Configuration” menu.
  3. Scroll down and find the “Action Keys Mode” setting.
  4. Change this from “Enabled” to “Disabled” using F5/F6 or the spacebar.
  5. Press F10 to save changes and exit BIOS.

Once these steps are complete, the Fn key will be disabled and function keys F1-F12 will work normally without needing to hold Fn. Keys like F2/F3 for brightness will then require holding Fn to activate their special feature.

What Happens When You Disable Fn Key on an HP Laptop?

With the Fn key turned off in BIOS, here is how your keyboard will operate:

1.    F1 through F12 will function normally without holding Fn

The most direct impact is that the F row keys like F5 refresh will work normally like on a desktop keyboard, without needing to hold Fn first. This makes using frequent function key shortcuts more seamless.

2.    You’ll need to hold Fn to use special features like play/pause media

Keys like F2 brightness and F3 volume will then require holding the Fn key to activate their special function. This is the reverse behavior, so you don’t trigger them accidentally.

3.    An Fn lock key allows you to quickly toggle between modes

HP provides a dedicated Fn lock key that lets you temporarily return to standard Fn behavior when you need access to the special functions. This convenient toggle caters to both use cases.

4.    Improved keyboard ergonomics for frequent Fn key users

For users who heavily rely on function keys, not having to constantly hold Fn reduces hand strain and fatigue. It provides a more comfortable long-term typing experience.

HP provides an Fn lock feature that lets you quickly switch between standard Fn behavior and disabled mode as needed. This gives you the best of both worlds, catering to your current needs.
