To help isolate the problem, try suspending from a root command line (s2ram)
or use the desktop environment menus. I find this reliable. Just closing the
lib often puts it in a state where it won't wake up. I don't think I've seen
the wakeup while closed, but I'm not possible.
This is on OpenSuSE 1.31 and a T520.
P.S. I'll try closing and opening the lid, then look at the system logs.
Thanks for noticing the multiple events.
