Hi Samuel, Could you please help to test Chris Chiu's patch to check if this issue is fixed on your machine? [PATCH v2] acer-wmi: Inform firmware that RF Button Driver is active http://www.spinics.net/lists/platform-driver-x86/msg10465.html Thanks a lot!
Totally forgot about this. But since I've recently reinstalled all the laptops and didn't run into this, I consider it fixed.
