** Description changed: + == 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.
