BugLink: https://bugs.launchpad.net/bugs/1801875 It leads to the power consumption raises to 2.2W during s2idle, while it consumes less than 1W during long idle if put SK hynix nvme to D3 and then enter s2idle. From SK hynix FE, MS Windows doesn't put nvme to D3, and uses its own APST feature to do the power management. To leverage its APST feature during s2idle, we can't disable nvme device while suspending, too. BTW, prevent it from entering D3 will increase the power consumtion around 0.13W ~ 0.15W during short/long idle, and the power consumption during s2idle becomes 0.77W.
