To turn off the Fn lock, the most common method is to press and hold the Fn key and then press the Esc key. This combination toggles the Fn lock on and off on many laptops and keyboards. When turned off, the function keys (F1-F12) work normally without needing to press the Fn key.
If the Fn + Esc method does not work, another way is to change the setting in the BIOS or UEFI firmware:
- Restart the computer and enter BIOS/UEFI by pressing a specific key during boot (commonly F2, F10, Del, or Esc depending on the manufacturer).
- Locate the setting related to Function Key Behavior or Action Key Mode.
- Disable the Fn lock or set Function Keys to behave as standard function keys.
- Save changes and restart.
Additionally, some keyboards use Fn + Caps Lock or other key combinations to toggle the Fn lock, so checking the keyboard markings or manufacturer manual can help.
For some external or specialized keyboards, software or drivers from the manufacturer may be required to manage Fn key functions.
Summary of ways to turn off Fn lock:
- Press Fn + Esc together.
- Check BIOS/UEFI settings and disable Fn lock or change function key behavior.
- Try Fn + Caps Lock if available.
- Update or install keyboard drivers or software if needed.
These methods cover the most typical scenarios to disable Fn lock on keyboards and laptops.
