Let's clarify one by one= : =20 + For the Fn key you said:=20 + key combos not working=20 =20 That a bit strange for at least the volume control (normally on Acer machine are Fn+up/down) should work because it direct send out useful scan code.=20 Please help to capture the scan code by showkey: - Add atkbd.softraw=3D0 kernel parameter and reboot system. - Switch to console and login with root account, then run: # showkey -s press Fn key and monitor the showkey output. + For we want to make sure acer-wmi causes any problem: Please add acer-wmi to the blacklist of modprobe (e.g. /etc/modprobe.d/blacklist), then try to reproduce all issues on your machine. (Fn key, AC power...) + For brightness control: Please check does there have /sys/class/backlight/acpi_video0 folder on your machine. If you found it, please try to change the backlight by= : # echo 3 > /sys/class/backlight/acpi_video0/brightness If you didn't see acpi_video0, please try 'acpi_backlight=3Dvendor' kernel parameter. Then /sys/class/backlight/intel_backlight should show up on your machine if it used Intel graphics Adapter. + For the AC power problem: Per your DSDT, the EC _Q37 is mapping to AC unplug and _Q38 is AC plug= =2E In _Q37 and _Q38, they notify AC, Battery and Processor acpi devices, but I didn't see it changed backlight. Did you set S3 suspend when lid close? Thanks a lot!
