4.3 Device Sleep Feature
Device Sleep (or DevSleep/DEVSLP) is the latest feature aligned with Intel® 4th Generation Core™-based
Ultrabook™. Ultrabook™ has stringent power requirements for SSDs and as such requires an ability to put the drive
in a low power state. Although Link Power Management allows some control over power consumption, both
methods still require the SATA link to remain online. The DevSleep pin is an “Enable” (High) pin which is pulled up
by the drive.
