--- Comment #3 from Johannes P (johannes.pens...@gmail.com) --- When pressing the brightness keys in Windows, the value read out from the B9 register does not change. To me, it looks like the EC tries to control the backlight itself, and there must be some way to enable "ACPI mode" for it to generate ACPI events instead. -- You may reply to this email to add a comment.
