I'm rumbling along with Vista Home Premium, and having the joy of seeing the screen blanker not kick in the way it should.

For instance, "Change when the computer sleeps" ... I can set this for 15 minutes, and it will work ... several times. I can leave the laptop and come back in an hour and the "sleep mode" has not kicked in and consequently the screen is still active.

Any ideas as to how I can overcome this thrilling snag?
