First, that's a bizarre thought, but you certainly could be right.

My thoughts, also unlikely:
- attach the power connection before powering on (connection glitch issue)
- attach charger and fully charge before powering on
   ("Battery fully charged pop-up issue)
- repeat the test in 32 bit (Live-CD, not reinstall)

I'm happy to offer thoughts, but happier that I don't have the problem.
