Once locked, you can press single F-keys (e.g., just F1 ) and they will behave as hotkeys (volume, brightness, etc.). To use standard F1–F12 while locked, hold Fn + the F-key.
To lock the Function (Fn) key on a Dell laptop, the most common method is using a keyboard shortcut. This toggles whether the top row of keys (F1–F12) acts as standard function keys or multimedia keys (like volume and brightness). Method 1: Keyboard Shortcut Press simultaneously.
Some older Dell models or those running specific Dell drivers allow you to change this setting directly within Windows.
Fn + Esc only works on built-in laptop keyboards. For external Dell keyboards, use BIOS or dedicated software.
