Bug description:
== SRU Justification ==
Impact:
Buggy ACPI table causes brightness unable to be adjusted, which means
certification testing also fails.
Fix:
Quirk this model so that it no longer follows the Win8 AML path.
Testcase:
Test brightness adjustment on the machine. Already verified by test
kernel on LP#1231305.
--------
CID: 201304-13196 Dell Inspiron 5537
Unable to adjust the screen brightness on this system.
Tested with 3.8.0-29 and 3.8.0-30 kernel.
Step:
1. Install 12.04.3 and boot to desktop.
2. Try to adjust brightness with the brightness keys.
2. Try to adjust brightness in "Brightness and Lock" of System settings.
Expected result:
Brightness could be adjusted by using the brightness keys and by adjusting in
"Brightness and Lock" of System settings.
Actual result:
1. Brightness keys events (keycode 224/225) were captured, but the brightness
cannot be adjusted. Brightness level indiciator only changes between Max and
Max - 1
2. Brightness cannot be adjusted in "Brightness and Lock" of System settings.
