*During periods of drive idle, some offline activity may occur according to the S.M.A.R.T. specification, which may increase acoustic and 
power to operational levels.
**Typical notebooks will pull power to the drive when entering S3 and S4; while in the S3 and S4 states, drive sleep and drive standby modes 
will not contribute to battery power consumption.
