I'm sorry if this subject allredy exists, but I really don't feel like reading all this.
The machine: HP compaq 6715s (never gonnna buy hp again!)
So the problem is simple: When I close the lid of my laptop or just click Shut down->Suspend,
and than try to return from stand by, the machine hangs(crashes).
I allredy saw that on some other computer(running Ubuntu), so I think it's the core(Ubuntu)'s problem.
By the way ... your green product is the best - high above everything else !
