The power buttons on both of my Aura HDs have always been flaky when it comes to powering on after a complete power-off. This behaviour has been there from new (at which time they were running firmware 2.something). The power button has to be slid sideways and held several times before power-up happens.
No problems at all with a quick flip of the power button to go into sleep mode or come out of sleep mode - that always works first time.
