/* Aggressive Link Power Management (ALPM) */
== Aggressive Link Power Management (ALPM) ==
* It's a mechanism where a SATA controller can put the disk into a very low power mode during periods of zero I/O activity and into an active power state when work needs to be done. Tests show that this can save around 0.4 Watts of some power and decrease mSATA average temperature.
* Create text file /etc/pm/power.d/sata_alpm
#!/bin/sh
* Make it executable
$ sudo chmod +x /etc/pm/power.d/sata_alpm
* Reboot, check that SATA power management policy have has been changed
$ cat /sys/class/scsi_host/host*/link_power_management_policy
