Yeah, I have ... and I get this after a resume: > intel_pmc_core INT33A1:00: CPU did not enter SLP_S0!!!

Hibernate works, and I do that when I know I won't be using it for a while, but going from a laptop that would give me nearly a week in S3 to this one where I can lose ~20-35% overnight sucks and I've been pulling at any straw trying to reduce s2idle power draw. -Kenny -- Kenneth R.
