-# When on AC, the machine either wakes up from sleep before being asked to

-# But the machine actually sleeps and resumes reliably when tlp is disabled
-# fully or partially.  Disabling RUNTIME_PM and AHCI_RUNTIME_PM appears to be
-# enough to allow it to work when tlp is active.  This will negatively effect
-# battery life.  I couldn't figure out a more granular way to get it working,
