After some more tests, I've found that if I move the mouse during the time the 
computer goes to suspend (just after clicking suspend in the systray), it 
doesn't supend at all but stay in the same states than after suspend/wake up 
(blank screen). May be this information can help to trouble shout this 
problem.
