Ben,

I remember two years ago, it seemed like the backlight of this laptop 
could be adjusted. At that time, I installed Ubuntu on this laptop and 
there seemed to be a directory called "acpi_video" in the 
"/sys/class/backlight/" directory. However, at some point, this 
directory no longer existed. At that time, I was not very familiar with 
Linux distributions and didn't know how to report bugs.

Regards,

larryw3i
