Function keys F1-F12 Laptops often work differently than desktop PCs. Instead of the usual commands (save, search, page refresh), they launch multimedia functions by default: adjusting volume, screen brightness or playback control. This feature is due to the compact layout of the keyboard and the desire of manufacturers to simplify access to popular settings.

If you need to use F1-F12 in their standard mode - for example, to work in Excel, Photoshop or games, you will have to temporarily or permanently disable the multimedia layer. Activation methods depend on the laptop model, BIOS version and operating system. In this article we will look at all possible methods, including hot combinations, BIOS settings and software solutions for Windows, macOS And Linux.

Why don't the top keys work as expected?

Laptop manufacturers (HP, Lenovo, Asus, Dell etc.) save space on the keyboard by assigning keys F1-F12 double function:

  • 🔊 Multimedia mode (default): adjust volume, brightness, turn Wi-Fi on/off.
  • 🖥️ Standard mode: functions F1-F12 (help, search, update, etc.).

Switching between modes is carried out using the key Fn (Function) or a special combination. However, on some models the multimedia layer is constantly activated, which interferes with work in professional programs. For example, in AutoCAD key F2 is responsible for panning, and in games F5 often used for quick saving.

An additional complication is the differences in implementation between different brands. Yes, on laptops Lenovo may require settings in the BIOS, and MacBook — changing parameters in macOS. Below we will look at universal and specific ways to solve the problem.

📊 What brand is your laptop?
  • HP
  • Lenovo
  • Asus
  • Dell
  • Acer
  • Apple
  • Other

Method 1: Temporarily switch using the Fn key

The fastest way to force the keys F1-F12 work in standard mode - hold the key Fn when pressed. For example, to use F5 to refresh the page in the browser:

  1. Clamp Fn (usually located in the lower left corner of the keyboard).
  2. Press the desired function key (for example, F5).

This method is suitable for one-time actions, but is inconvenient for frequent use. In addition, on some laptops (Dell XPS, HP Spectre) key Fn may be blocked or require additional settings.

💡

If the key Fn does not work, check if the mode is activated Fn Lock. On some models (Lenovo ThinkPad) to do this you need to press Fn + Esc.

Method 2: Permanently disable multimedia mode in BIOS/UEFI

If you need the keys F1-F12 always worked in standard mode, change the setting in the BIOS. This method works for most laptops. Windows And Linux:

  1. Reboot your laptop and enter the BIOS by clicking Del, F2 or Esc (depending on the model).
  2. Find a section System Configuration or Advanced.
  3. Look for the parameter Function Key Behavior, Hotkey Mode or Action Keys Mode.
  4. Set value Disabled (for standard mode) or Legacy.
  5. Save changes (F10) and reboot.

On laptops Lenovo the path might look like this: Configuration → HotKey Mode → Disabled. On HP — System Configuration → Action Keys Mode → Disabled.

What to do if the BIOS does not have the required setting?

On some budget models (for example, Acer Aspire or Asus Vivobook) option is missing. In this case, use the software methods (see Method 3) or update the BIOS to the latest version.

Laptop brand Option in BIOS Recommended value
Lenovo (ThinkPad, IdeaPad) HotKey Mode Disabled
HP (Pavilion, Envy, Omen) Action Keys Mode Disabled
Dell (Inspiron, XPS, Latitude) Function Key Behavior Function Key
Asus (ZenBook, Vivobook) Function Keys Mode Normal
⚠️ Warning: Changing BIOS settings may cause system instability if incorrect settings are selected. Before making changes, write down your current settings or take a photo of the screen.

Method 3: Programmatic control of function keys in Windows

If you don't want to go into the BIOS, use the built-in tools Windows or third party utilities. For example, on laptops Lenovo And Dell There is proprietary software for controlling the keyboard:

  • 📥 Lenovo Vantage (for Lenovo): section Input → Keyboard → Function Key Mode.
  • 🖥️ Dell QuickSet (for Dell): tab Function Keys.
  • 🔧 HP Hotkey Support (for HP): setting in Control Panel → Devices and Printers.

For a universal solution, the utility is suitable SharpKeys (free). It allows you to reassign keys at the registry level:

Download the utility from the official website|Run as administrator|Add a rule for reassignment (for example, F1 → F13)|Apply changes and restart PC-->

Alternative - AutoHotkey. Script for automatic retention Fn:

#NoEnv

SendMode Input


SetWorkingDir %A_ScriptDir%



; Отправляет F1 с зажатой Fn


F1::Send {Fn down}F1{Fn up}


; Повторите для F2-F12
⚠️ Attention: Reassigning keys through the registry (SharpKeys) may conflict with keyboard drivers. Before making any changes, create a system restore point.

Method 4: Features on Apple laptops (MacBook)

On MacBook keys F1-F12 by default they perform system functions (brightness adjustment, Mission Control, etc.). To return to standard behavior:

  1. Open System Preferences → Keyboard.
  2. Activate the option Use the keys F1, F2, etc. like standard function keys.
  3. For one-time use, hold Fn (on new MacBook — Globe).

On MacBook Pro with Touch Bar Function keys only appear on the screen in certain applications (for example, Final Cut Pro). To ensure they are always available:

  • 🔄 Go to System Preferences → Keyboard → Keyboard Shortcuts.
  • 🖥️ Select App Shortcuts and add the required combinations manually.

On a MacBook with an M1/M2 chip, the F1-F12 keys may not work in Windows via Parallels or Boot Camp due to missing drivers. In this case, use a virtual keyboard or reassign the keys through utilities like Karabiner-Elements.

Method 5: Solution for Linux (Ubuntu, Fedora, Arch)

In distributions Linux Function key control depends on the keyboard driver. For most laptops, setup via xmodmap or setkeycodes.

First determine the key codes with the command:

xev | grep keysym

Then create the file ~/.Xmodmap with lines:

keycode 67 = F1 F1 F1 F1 F1 F1 XF86Switch_VT_1

keycode 68 = F2 F2 F2 F2 F2 F2 XF86Switch_VT_2


; Повторите для F3-F12

Apply changes:

xmodmap ~/.Xmodmap

For permanent effect, add the command to startup (~/.xinitrc or ~/.config/autostart/).

On laptops Lenovo may need to be disabled ideapad-laptop module:

echo "blacklist ideapad_laptop" | sudo tee /etc/modprobe.d/ideapad.conf

Common problems and their solutions

Even after key settings F1-F12 may not work correctly. Let's consider typical situations:

  • 🔌 Keys don't respond at all: Check the keyboard driver in Device Manager (Windows) or through lsusb (Linux). Update or reinstall the driver.
  • 🔄 Functions are mixed up: For example, F5 turns on highlighting instead of page refresh. This indicates a driver conflict. Try rolling back the system to a previous restore point.
  • 🖥️ Only works in BIOS: If the keys function in the BIOS but not in the OS, the problem is in the software. Install original drivers from the manufacturer's website.

On laptops with hybrid graphics (NVIDIA Optimus) keys F1-F12 may conflict with video card drivers. Solution:

  1. Update your driver NVIDIA to the latest version.
  2. B NVIDIA Control Panel turn off Optimus for the current application.
💡

If the keys stop working after updating Windows, try rolling back the keyboard driver through Device Manager (RMB → Properties → Roll Back).

FAQ: Answers to popular questions

  • Disable the media layer in BIOS (see Method 2).
  • Reassign keys via SharpKeys or AutoHotkey.
  • Use external keyboard with default behavior F1-F12.
Why do the F1-F12 keys work as multimedia keys again after reinstalling Windows?

The reason is resetting the BIOS settings to factory settings or installing standard Windows drivers instead of proprietary ones. Solution:

  1. Install the keyboard driver from the official website of the laptop manufacturer.
  2. Check your BIOS settings (maybe Action Keys Mode activated again).
  3. For Lenovo And Dell install proprietary software (Lenovo Vantage, Dell QuickSet).
How to turn on the keyboard backlight if F5 is reassigned to the standard function?

If you have disabled multimedia mode, use alternative methods:

  • Click Fn + Space (on some models HP And Asus).
  • Use proprietary software (for example, MyASUS for Asus).
  • Set up hotkeys via Windows Settings → Devices → Keyboard.
Does this method work on gaming laptops (ASUS ROG, MSI, Alienware)?

Yes, but with nuances:

  • On ASUS ROG use the utility Armoury Crate to control the keys.
  • On MSI And Alienware the setting is available in the BIOS under the name Function Key Lock.
  • Gaming laptops often have additional Fn-mode that is activated by a combination Fn + Caps Lock.
Is it possible to customize individual keys (for example, only F5 as the default)?

Yes, but only programmatically:
