For a user, fn-lock is similar like caps-lock, scroll-lock or num-lock. Also fn-lock is provided by other laptops and therefore I would expect that kernel provide fn-lock state for all laptops (thinkpad / latitude / ...) via same interface. And not via dell-specific interface or general-vendor-message interface. Wrong power adapter sounds like something related to power subsystem. Adding Sebastian to the loop, maybe he can provide some useful ideas about it. And plugged dock into wrong port. This is probably dell-specific event and some interface for "vendor" messages from kernel to userspace would be needed to deliver such things.
