Lenovo ThinkPad W Series :: W540 - Toggling WiFi Power On Mains Shifts To Airplane Mode

Each time I try to turn off the WiFi when connected to the mains, the unit goes into airplane mode.

1] Any work around so the WiFi is turned off IMMEDIATELY and still remain with the W540 connected to the power supply (mains)??

There has to be a way to quickly turn off the WiFi without going into battery mode.

2] Similarly, is there a way to turn off the WiFi during boot up or before the system is fully booted.

I checked the power setting Lenovo software, but I find it very convoluted for such a simple workstation task.

As an answer to the original post:  On long d/l's with slow lines, I have not found anyway to turn off the screen deliberately. Closing the lid does turn off the screen, but the screen turns on when the lid is opened.  Having the screen on in an hotel room is a nuisance, similarly when leaving the system on while away, and the cleaning people see the unit is turned on.  I gave up, and do not travel with the W540, as I have yet to find a workaround. I do manage with my other brand workstation.
