How to get my laptop to go into sleep or hibernate mode

English Install/Boot/Login

Installed openSUSE into my Thinkpad T410 and noticed that when I closed the laptop lid, the moon icon does not light up.

Reopening the lid and will see a screensaver password screen immediately.

Does this means that the laptop does not have Sleep (or is it called hibernate) mode enable? How can I enable it?

This also happens with Debian that this laptop is dual booted with.

Managed to found out what I’ve done wrong :\

For KDE users, go to the menu
-> Power Management
-> Chose the Profile as Power-Save
