Thank's for your testing, it's help to confirm our value write to EC register. Unfortunately, I have no idea why the EC didn't change brightness level even the BLVL register was changed. I will try to trace DSDT hope can dig more information. This issue MIGHT not related to acer-wmi driver. I wonder how does the brightness control key works on Windows 7, I thought we need EC expert's help. On the other hand, For detect wireless/bluetooth device state and killswitch support, I need more time to clear up current acer-wmi source code to support your machine. I will attached on acer-wmi patch for support your machine ASAP. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. ------------------------------------------------------------------------------ Simplify data backup and recovery for your virtual environment with vRanger.
