I usually resume from suspend by pressing the space bar or other random keys on the keyboard, but I have also tried resuming by pressing the power button. (This laptop has a visible switch to suspend when the lid closes, but it does not resume when the lid opens.) As always, the laptop-s display is unusably scrambled after resume EXCEPT while the processor is near 100%.
