[ubuntu] Eee PC 1011CX Ubuntu 12.4.1 LTS: No hibernate option in power settings

view story

http://ubuntuforums.org – Hi, I have Eee PC 1011CX running Ubuntu 12.4.1 LTS. I do not see hibernate option in power settings. I can see only "do nothing" or "suspend". So the issue is that if I simply leave the computer with lid closed (I have set "closing the lid" to "suspend"), battery completely dies out after some time and I have to start recharging again though I may not have used it at all. How can i solve this? "Hibernate" is not highlighted in power options. (Hardware)
