How to Add or Remove "AHCI Link Power Management - Adaptive" from Power Options in Windows


The AHCI Link Power Management - HIPM/DIPM setting in Power Options allows users to configure the link power management mode for disk and storage devices that are attached to the system through an AHCI interface. AHCI Link Power Management is a technique where the SATA AHCI controller puts the SATA link to the internal HDD and/or SSD disk into a very low power mode when there.

The AHCI Link Power Management - Adaptive setting in Power Options specifies the period of AHCI link idle time in milliseconds before the link is put into a slumber state when Host-Initiated Power Management (HIPM) or Device-Initiated Power Management (DIPM) is enabled.

By default, AHCI Link Power Management - Adaptive is set to 0 (Only use partial state).
