* Takashi Iwai -- Saturday 30 April 2011:
I remember vaguely that the value zero could be interpreted as the max.
Also, with the patch, does the backlight level can be adjusted correctly to different values? I wonder whether LBPC adjustment really works or not on your machine.
if (!lbpc)lbpc = 0xff; /* max value */
This change does *not* work on my machine. The screen stays black again.
Yes, backlight adjustment generally works on this notebook, but only with "acpi_osi=Linux" on the command line.
