Help! New ASUS K53z laptop that has a fresh Ubuntu 12.04 install... However, sleep doesn't work... Tried to follow the manual process in this thread... http://ubuntuforums.org/showthread.php?t=1460790 The dropbox package was a 404, and my results are working... closing the lid of the computer shuts the wireless off, and the screen remains lit up. I'm a relative novice, but have been trying to work in terminal and follow instructions, but with this one I'm having little success.
