XPS 13 9360: BIOS 1.3.2 - "Fn Lock Options", the 2 Config Options are Switched **UPDATED: still here in BIOS 2.2.1**
In the Dell XPS 13 (9360). Using the latest BIOS 2.2.1 (but the old previous BIOS version was the same).
If you go to the "Fn Lock Options" under BIOS, there are 2 options, they are listed as:
Lock Mode Disable/Standard = The F1-12 Keys behave as function keys
Lock Mode Enable/Secondary = The F1-12 Keys control the secondary functions.
These options are Swapped. If you disable the "Fn Lock" and set the mode to "Lock Mode Disable/Standard", log into Windows, and Press F1, it will then MUTE the system. Even though it should act like an "F1" Key.
If you go back into BIOS, set the mode to "Lock Mode Enabled/Secondary", log into the system and Press F1, then the Help comes up.
The options are swapped on these two configure options. Please update the text in the BIOS to match the appropriate configuration. Thanks. I've included a ScreenShot of the BIOS options. "Fn Lock" does do what it describes (disables Fn-Esc). Doesn't matter if u turn this on or off. If you have it set up as I do below, the Fn Keys are set for the proper Function (F1-F12) operation. However, the text says it should do its secondary functions in this mode.
