Hi guys! I really need your help.
I have notebook ASUS N750JV with windows 10 on the board.
I've encrypted my system drive and everything went successfully.

When I am entering my password in UEFI (black screen) with embedded laptop's keyboard - its always wrong. I am sure that entered it correctly!
But when I am using external USB keybord - computer starts and password is correct!

Password contains only english letters and numbers, without any exotic characters.

looks like EFI treating some characters from those keyboards in different way.
What can be wrong? And how I can start use my laptop normally with its own kayboard?
