How to enable DIPM for SSDs on Windows 7:

NOTE:
this won't work if your SSD isn't connected to an AHCI controller


1. Run Registry Editor (type "regedit" in the search field on the Start Menu).

2. Navigate to "HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Power\PowerSettings\0012ee47-9041-4b5d-9b77-535fba8b1442\0b2d69d7-a2a1-449c-9680-f91c70521c60".

3. Change value "Attributes" to 2. At this step you won't have modified ANY functionality in Windows (except for a tiny detail in the power management USER interface), so it's 100% safe.

4. Reboot.

5. Now go to "Power Management" in Control Panel and click "Change plan settings" of your power plan, then click "Change advanced power settings".

6. Expand the "Hard Disk" settings tree. You'll see that now there is and ADDITIONAL setting: "AHCI Link Power Management - HIPM/DIPM". Expand this one.

7.1. If you have a LAPTOP: change "On battery" and/or "Plugged in" to "HIPM+DIPM" as you like. Intel recommends that DIPM be enabled at all times for its SSDs. If that's your case, change both.

7.2. If you have a DESKTOP: change "Setting" to "HIPM+DIPM".

Voilá. There's a small impact on drive performance (which I could only notice after running a benchmark). My system "felt" quite the same.

NOTE:
For Intel SSD owners only): now Intel SSD Toolbox does the job, but does it another way around, bypassing the Windows shell
