Windows 7 Ultimate on DV6-2044CA
So brightness works well when i turn on the cmoputer from shut down.
I can change it, use mobility center to change it, use power options to change it, use FN + Fx keys to change it.
Then i go to sleep mode as i travel around (laptop) and when i turn it back on, the brightness is much dimmed (about 60%) and i cannot change it.
In fact, the brightness box in Mobility Center has disappeared..
Power options, whenever i use the brightness slider, no effect...
FN + Fx keys do not work, also.
The solution is to either enter hibernation mode, and turn it back on or to Shut Down, then turn it back on...
Possible workaround ways???
