Hello Guys! I am running my first Hachintosh [Mac Lion] fairly good, but I have a problem with the sleep and brightness. The sleep doesn't work, the screen goes black and remains black even if I try to wake it up. I have to shutdown my laptop manually to get back to the desktop. The brightness doesn't work, I can't adjust brightness, the screen remains on 100% bright, which is killing my eyes and battery. Does anyone have the DSDT file to enable the sleep and brightness ? Or knows another way? Laptop specifications: [Acer 5750-9292] •Intel Core i7 2GHz •Built in INTEL HD Graphics 3000 •4 GB DDR3 RAM My Extracted DSDT file is attached. Thanks in advance!
