Notes on Auto Acoustic Management (AAM) and APM support
AAM and APM settings are vendor-specific and not all intermediate values may be valid. If you set an invalid APM value you will be notified that it failed - when setting an AAM value you should check the output of ataidle <device> to see if it has been updated. If it hasnt, the value isnt supported and you should try a higher or lower setting.
Meaning of AAM values:
0 Acoustic management disabled. 1 Minimum noise. 2-126 Intermediate noise levels. 127 Maximum performance, maximum noise.
Meaning of APM values:
0 APM disabled 1 Minimum power usage with Standby (spindown). 2-127 Intermediate power usage with Standby. 128 Minimum power usage without Standby (no spindown). 129-253 Intermediate power usage without Standby. 254 Maximum performance, maximum power usage.
