Hello, first I'm sorry about my english but I'm French.
I successfully installed Lion 10.7.2 via iAtkos L2 with QE/CI working on a Lenovo G570 (Intel Core i3-2310m with HD 3000 Graphics)
I can set brightness following this post : http://www.insanelymac.com/forum/index.php?showtopic=236835&st=0 but I have a problem.
The brightness steps aren't good : when the slider is on 0, screen goes black but if I put slider on 1 position, brightness is at 50/60%, which is too high.
I think we can fix this with DSDT but I don't know how.
Also I need LID fix, a FAN fix because they never stop, and verify if power management option are correctly implemented.
There is my DSDT : http://www.mediafire.com/?9vkjbj8nw1qh73s
Thanks for your replies.
