After copying DSDT.aml to the APCI folder and restarting the computer. After the computer is turned on, I press the F12 button to increase the screen brightness, it works fine, but when I press the F11 button, my computer turns off the black screen and then I press the power button twice and the computer turns on. My computer works properly again and displays the screen to enter the password. How to fix button F11. Thanks.
