Hi,

if I try to change the Backlight Brightness of my Laptop, the System is rebooting.

Here is what I've try to set the Brightness.

Code:

echo 3 > /sys/class/backlight/acpi_video0/brightness


I've also found a "[Firmware Bug]: ACPI _BQC method ..." Message in the dmesg

Please find the attached File, wich contains any logs I found.
