12.5.6Initial Power Mode at Power On

After power on the device goes to IDLE mode or STANDBY mode depending on the setting of the Power Up in Standby Feature set

12.6 Advanced Power Management (Adaptive

Battery Life Extender 3) Feature

This feature provides power saving without performance degradation. The Adaptive Battery Life Extender 3 (ABLE-3) technology intelligently manages transition among power modes within the device by monitoring access patterns of the host.

This technology has three idle modes; Performance Idle mode, Active Idle mode, and Low Power Idle mode.

This feature allows the host to select an advanced power management level. The advanced power management level is a scale from the lowest power consumption setting of 01h to the maximum performance level of FEh. Device performance may increase with increasing advanced power management levels. Device power consumption may increase with increasing advanced power management levels. The advanced power management levels contain discrete bands, described in the section of Set Feature command in detail.

This feature set uses the following functions:

A SET FEATURES subcommand to enable Advanced Power Management

A SET FEATURES subcommand to disable Advanced Power Management

The Advanced Power Management feature is independent of the Standby timer setting. If both Advanced Power Management level and the Standby timer are set, the device will go to the Standby state when the timer times out or the device’s Advanced Power Management algorithm indicates that it is time to enter the Standby state.

The IDENTIFY DEVICE response word 83, bit 3 indicates that Advanced Power Management feature is supported if set. Word 86, bit 3 indicates that Advanced Power Management is enabled if set.

Word 91, bits 7-0 contain the current Advanced Power Management level if Advanced Power Management is enabled.

12.6.1Performance Idle mode

This mode is usually entered immediately after Active mode command processing is complete, instead of conventional idle mode. In Performance Idle mode, all electronic components remain powered and full frequency servo remains operational. This provides instantaneous response to the next command. The duration of this mode is intelligently managed as described below.

12.6.2Active Idle mode

In this mode, power consumption is 45-55% less than that of Performance Idle mode. Additional electronics are powered off, and the head is parked near the mid-diameter of the disk without servoing. Recovery time to Active mode is about 20ms.

12.6.3Low Power Idle mode

Power consumption is 60%-65% less than that of Performance Idle mode. The heads are unloaded on the ramp, however the spindle is still rotated at the full speed. Recovery time to Active mode is about 300ms.
