Hi Pavel,
I'll try to test this weekend.

Out of curiosity, what did you change compared to the original version
of the driver? Did you just disable the set up code?

Also, how do you try free fall? Did you try also with the lid opened?

Why a special case if the lid is opened and the laptop unplugged? Is it
a special behaviour of the hardware, or simply some kind of basic user
behaviour guess?

See you,
