Hello. I have updated to the latest BIOS release for my machine, but the screen brightness still does not change when I use the brightness controls (the onscreen brightness "slider" moves, but the actual screen brightness does not change).
The output from the "dmidecode" command is; R0170D6 03/13/2012 Regards, David Peck. On 9 August 2013 03:23, Christopher M.
