See if the Volume/Mute/Brightness works if you hold the "Fn" key simultaneously. There's an "Fn Lock" setting in the BIOS and/or software-accessible that gets toggled inadvertently. Just this week, I had customers complaining their Wifi keeps getting turned off, and their F8 is no longer working like it used to, and that was the cause.

I have a Dell Precision 5520 laptop (basically an XPS 15). The volume,

Something has changed in the last week or two, and the keys no longer
have any effect (except that the brightness increase key now toggles
the maximized state of terminal windows).
Anyone else seen this recently?
Assuming no, anyone have any hints on how to debug this? I'm not really
sure how these function keys work (i.e. are they keypresses, ACPI
events, something else?).
Any thoughts appreciated. Thanks!
