Acer 2920 - Suspend doesn't work

Hi mates,
I have a problem with suspeding my NB to the RAM. It goes down fine, but when I try to wake up NB, it turns down like during restart and starts, but screen is black and there is no response on any actions, so I have to turn NB off. Any suggestions?:\

EDIT: Hibernation to HD works fine.

Gyus, ply help me! It’s important issue…

Which version of Opensuse do you use? Do you use KDE or GNOME?

Post more details about your hardware. For a start laptop brand and model may be helpful. Also graphics and network chipsets via
