But they cannot do both at the same time. If you want to use the F1-F12 keys for their secondary functions of controlling multimedia or your screen settings, use the steps here to disable them on the laptop. The behavior of the Functions keys can be controlled by the Function Lock (Fn Lock) found under BIOS or UEFI settings.

On the right, select the check box for Fn Lock if it’s unchecked. The Fn Lock has two options which are self-explanatory: Lock Mode Disable/Standard: The F1-12 Keys behave as function keys. You must hold down the Function key and any of the F1-F12 keys to trigger a command.Lock Mode Enable/Secondary: The F1-12 Keys control the secondary functions.

How Do I Disable the Fn Key
There is no dedicated Fn Lock key on most Dell laptops to disable the F1 to F12 Function keys. The Function Lock is enabled/disabled by pressing the Escape key (on the top row next to the F1 to F12 keys) and Function key (on the bottom row next to the Windows button) together like a toggle switch.

Increasing the playback volume could be the secondary function of the F5 key, as indicated by a small icon below the F5 label. Enabling Fn Lock allows you to execute any standard functions tied to the F1 through F12 keys without pressing the Function key always.
