Adjust the level of brightness
Hi all I would like to start a new topic so as to be useful to all those who are in my condition. I installed OSX 10.8.2 on my tab but the brightness level is too low. I would like to raise the bar but do not know how .....
I read method _BCL _BCM and values to be changed in order to obtain the desired level even someone can help me? Code:
Method (_BCL, 0, NotSerialized)
{
Store (0xB0, BSUP)

what's your system anyway? I had installed hackintosh in acer 4745 (it my memory serves me right) and it is accessible via keyboard shortcut. Fn+f12 going up and Pause/Break for low. If you have keyboard with function key in it, better try to experiment.
