Is your AHCI Link Power Management viewable from the Power Options Console?

If you can’t see your AHCI Link Power Management from the Power Options, there is a way to add it.  Always backup your computer before modifying the registry.

You can add the GUID to the registry by going opening the registry (regedit) and creating  a key under the following key -0012ee47-9041-4b5d-9b77-535fba8b1442

The easiest way is to copy the information in italics to notepad or notepad++ and save as AHCI.reg.

After saving this, double click on the .reg file and reboot.

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\0012ee47-9041-4b5d-9b77-535fba8b1442\0b2d69d7-a2a1-449c-9680-f91c70521c60]
