Hi guys, My Macbook 5,1 is not sleeping when i close the lid anymore? Is there a setting i am missing in ML? I have changed quite a few variables lately (installed a SSD in place of the old HDD which i put in a data doubler in the optical drive slot) and upgraded the ram to 8 gigs. i suspected that the data doubler might be the culprit, but "ejecting the disc" doesn't fix the problem. i can make the computer sleep manually, but just closing the lid doesn't do anything. doesn't even turn the screen off. any ideas? thanks!
