Simulate Fn+F11 key press

Question

Can you tell me how I can simulate key presses Fn + F11 on a laptop? Do I have to write a driver, or something like that?

The platform is Windo

Answer 1

Won't work. The Fn-F11 key combo on laptops isn't handled by the OS; it's processed in Systems Management Mode - a BIOS feature, essentially.

Answer 2

I recently had to simulate F5 press to cause a refresh in a web browser:

INPUT inp[2]= {0};
inp[0].type = INPUT_KEYBOARD;
inp[0].ki.wVk = VK_F5;
inp[1].type = INPUT_KEYBOARD;
inp[1].ki.wVk = VK_F5;
inp[1].ki.dwFlags = KEYEVENTF_KEYUP;

SendInput(2, inp, sizeof(INPUT));

To simulate the Fn + FX Key you might have to search for special codes.
