Suspend and hibernate does not work.

[CProgramming]

Hello .. I need help guys.
I have Ubuntu 11.10 on Asus k53e .
When I try suspend or hibernate the laptop ,
I got black screen until I turn off the computer manually (by pressing ~10 secs on the power button).

There is some fix or solution for this problem?

Note: when I had widnows 7 , the sleep (which called "suspend" in ubuntu) and hibernate worked as well. But win7 crash every 2 secs so I don't wanna use it. And this howTo topic : http://ubuntuforums.org/showthread.php?t=471855 did not help me :\ The problem still exist.
Thanks !

Have a look at the solution listed here: http://thecodecentral.com/2011/01/18...ot-working-bug. According to the comments, this procedure worked on a similar system.
