What function keys do and why you might want to disable them

Function keys are the row of keys labeled F1 through F12 at the top of your keyboard. On HP laptops, they often control things you did not ask for — volume, brightness, airplane mode, or media playback — instead of doing what older software expects them to do. When you press F5, you might want to refresh a spreadsheet, but your laptop dims the screen instead.

Most HP laptops have two modes for these keys. In one mode, they act as media controls. In the other, they work as traditional function keys for programs. You can switch between these modes, or lock one mode permanently so you do not have to hold an extra key every time.

The method depends on your HP model and whether you have a physical Fn key (usually bottom-left of the keyboard, next to Ctrl). Some newer HP models do not have a dedicated Fn key at all, which changes how you access the setting.

Key Takeaways

  • Most HP laptops let you swap function key modes through the BIOS setup screen, which you enter by restarting and pressing a specific key during startup.
  • If your HP has a physical Fn key, you can usually hold it while pressing a function key to get the opposite behavior without changing any settings.
  • Some HP models have a setting in Windows itself under keyboard or device settings that controls function key behavior.
  • If you cannot find the setting in BIOS or Windows, your laptop model may require a driver update or may not support changing this behavior.

Entering BIOS to change function key behavior

The most reliable way to disable function key media controls is through your laptop's BIOS — the low-level software that runs before Windows starts. Restart your HP laptop and watch the screen carefully as it boots. Within the first few seconds, you will see a message saying something like "Press Esc for Startup Menu" or "Press F10 for Setup." The exact key varies by HP model.

If you see "Press F10 for Setup," press F10 when ready. If you see "Press Esc for Startup Menu," press Esc first, then look for an option labeled "System Setup" or "BIOS Setup" in the menu that appears. You have only a few seconds before the laptop continues to Windows, so be ready.

Once you are in the BIOS setup screen, look for a section called "System Configuration," "Onboard Devices," or "Advanced." Inside that section, find an option with a name like "Function Key Behavior," "Fn Key Behavior," "Action Keys Mode," or "Multimedia Keys." The exact wording differs between HP models.

When you find this setting, you will usually see two choices: one that says "Multimedia" or "Media Keys" (the current behavior), and one that says "Function Keys" or "Standard." Select "Function Keys" or "Standard," then save and exit. Your laptop will restart, and the function keys will now work as traditional F1–F12 keys instead of controlling volume and brightness.

Using the Fn key as a temporary workaround

If you do not want to enter BIOS, or if your HP model does not have a BIOS setting for this, you can use the physical Fn key on your keyboard. On most HP laptops, this key is in the bottom-left corner, next to the Ctrl key. When you hold Fn and press a function key, it does the opposite of what it normally does.

So if F5 normally dims your screen, holding Fn and pressing F5 will refresh your spreadsheet instead. This takes an extra keystroke every time, but it works without changing any settings. If you use traditional function keys often, this becomes tedious quickly — which is why changing the BIOS setting is usually worth the effort.

Some HP models have a physical button or key combination that locks the Fn key into "function key mode" so you do not have to hold it. Look for a key labeled "Fn Lock" or try pressing Fn and Esc together — on some models, this toggles Fn Lock on and off. If it works, you will see a small light turn on near the Fn key or in your system tray.

Checking Windows settings for keyboard options

Newer HP laptops sometimes put this setting in Windows itself rather than in BIOS. Open the Windows Start menu and type "keyboard settings" into the search box. Click the result that says "Keyboard settings" or "Keyboard" under Settings.

Scroll down and look for an option that mentions "Function Keys," "Fn Keys," "Action Keys," or "Multimedia Keys." If you see one, click it and look for a toggle or dropdown that lets you switch between modes. Some HP models label this as "Change what your function keys do" or similar.

If you do not see this option in keyboard settings, try opening Device Manager. Right-click the Start button and select "Device Manager," then look for "Keyboards" in the list. Expand it, right-click on your keyboard, and select "Properties." Check the "Advanced" or "Driver" tab for any settings related to function keys. Not all HP keyboards have this option, but some do.

Updating or reinstalling your keyboard driver

If you cannot find the setting in BIOS or Windows, your keyboard driver may be outdated or missing. Open Device Manager again, find your keyboard under "Keyboards," right-click it, and select "Update driver." Choose "Search automatically for updated driver software" and let Windows search for a newer version.

If an update is found, install it and restart your laptop. After the restart, check keyboard settings again — the function key option may now appear. If no update is found, try right-clicking the keyboard again and selecting "Uninstall device." Restart your laptop, and Windows will reinstall the driver automatically. This sometimes restores missing settings.

You can also visit the HP support website, enter your laptop model number, and read the latest keyboard or chipset driver directly. Install it and restart. This is more reliable than letting Windows search, especially on older HP models.

What to do if your HP model does not support this change

Some HP laptop models, particularly older ones or budget models, do not allow you to change function key behavior through BIOS or Windows. If you have searched BIOS thoroughly and found no option, and Windows settings show nothing, your model likely does not support it.

In this case, your best option is to use the Fn key workaround — hold Fn whenever you need a traditional function key. Alternatively, many programs let you remap keys. For example, if you use a spreadsheet program that needs F5 to refresh, you can often set it to use a different key combination instead. Check your program's settings or preferences for a "Keyboard Shortcuts" or "Hotkeys" section.

You can also use third-party remapping software like AutoHotkey (free, Windows only) to reassign function keys globally across all programs. This requires some setup, but it works on any HP model. Search for "AutoHotkey function key remap" to find guides specific to what you need.

Frequently Asked Questions

Will changing function key behavior affect other programs or settings?

No. Changing the function key mode in BIOS affects only how those keys behave — it does not change anything else on your laptop. If you change it back later, everything returns to normal. The Fn key workaround also does not affect other settings.

How do I know which key to press to enter BIOS on my specific HP model?

Restart your laptop and watch the screen during startup. You will see a message in the first few seconds that tells you which key to press — usually F10, Esc, or Del. If you miss it, restart and try again, watching more carefully. If you still cannot see the message, try pressing F10 or Esc repeatedly as soon as you see the HP logo.

Can I change function key behavior back to media controls if I change my mind?

Yes. Go back into BIOS using the same method, find the function key setting, and select "Multimedia" or "Media Keys" instead. Save and exit. Your function keys will return to controlling volume and brightness. You can switch back and forth as many times as you want.

What if I accidentally changed something else in BIOS and my laptop is not working right?

Restart and enter BIOS again. Look for an option called "Load Defaults," "Restore Defaults," or "Reset to Factory Settings." Select it, save, and exit. This puts all BIOS settings back to how they were when you bought the laptop. Then you can make just the function key change again.

Does disabling function keys use less battery power?

No. Changing how function keys behave does not affect battery life. The keys work the same way internally — only what they do changes.
