AHCI Link Power Management manages the various power management modes for disks and storage devices, which are connected to the main system via AHCI interface. The different modes of AHCI Link Power Management are:
- Active – Neither HIPM or DIPM is allowed. In this case, link power management is disabled.
- HIPM – HIPM stands for Host Initiated Link Power Management. For this mode, HIPM can be used only.
- DIPM – Device Initiated Link Power Management only can be used.
- HIPM + DIPM. Both HIPM and DIPM can be used.
- Lowest – HIPM, DIPM, and DEVSLP are activated. DevSlp or DevSleep are also referred to as SATA DEVSLP. This feature enables a SATA device to go to a low power sleep mode.
Based on your hardware, you can choose any one of the above modes.
