OK, well, this is odd... I shortened it to 5 seconds after setting (APM?) to S3 only. So that was a bit odd. Why would that matter when I never hibernated it?
Still have this problem, even with my new Gigabyte P55-USB3 motherboard.
So it wasn't my previous P7P55D-E that was the problem. Could it be a P55 chipset issue?
