This is normal.  Every laptop I've used (even in Windows) expects to be woken
from sleep states with the power button - if your laptop had a dedicated sleep
button, you might use that instead, but the lid switch is never, ime, used for
wakeup.

This, however, seems wrong.  What you should get when you wake with the power
button is a power button event immediately followed by a lid switch event - and
then any other events.
