I follow this document, but looks like "kernel not translating the ACPI event to an input event".
"sudo /lib/udev/keymap -i input/event4" not shown any reaction to Fn+F4 and Fn+F5 in my case.
Also I see the two other possible problems:
1. Fn+F3 (button for switch between laptop LCD and external monitor) generate same scancode like "p" button.
2. PrtScr and Fn+PrtScr generate same scancode, but Fn+PrtScr must generate SysRq scancode.
When I test I found the BIOS of this laptop have "key release" event problem. Desktop sticks many times while testing. If it possible to fix using BIOS update, what I can exactly request from this laptop manufacturer for fixing in next BIOS update? I mean there is any description of the problem in technical language?
