Sleep and re-activation

[anonprivate]

When I set KUBUNTU to sleep I tried to reactivate it by pressing keys. But it did not re-activate. I needed to press the off button quickly once to re-activate the OS. Is there a key I can use?

Thanks

I just move the mouse a bit; the computer is like a person, sometimes we wake up a little slow and need a shaking.
