Your previous work to support DEVSLP works well on SATA SSDs, so I am asking you the issue I am facing:
Once a laptop has a HDD installed, the power consumption during S2Idle increases ~0.4W, which is quite a lot.
However, HDDs don't seem to support DEVSLP, so I wonder if you know to do proper power management for HDDs?
