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...

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.

Before enabling hibernation, please try to test whether it works correctly by running pm-hibernate in a terminal. The system will try to hibernate. If you are able to start the system again then you are more or less safe to add an override.

To do so, start editing

sudo nano /etc/polkit-1/localauthority/50-local.d/com.ubuntu.enable-hibernate.pkla

Fill it with this

[Re-enable hibernate by default]

Save by pressing Ctrl-O and exit nano by pressing Ctrl-X

Restart and hibernation is back!

Some users will then need to run sudo update-grub to get the hibernate option to be available in the power menu..

Take this how-to from Hibernation
