I see a dsdt for an EP35-DS3L, but not P35-DS3L, worth a shot?

The last few restarts have been good, but still no sleep on idle. Could it be because I have no DVD drive connected? I know some drives are causing issues, so what about having none, like I do? haha maybe I'm just hoping for a quick fix.

Edit:
In your guys' experience, if GFX is enabled through DSDT, is it simply a matter of it working or not working? I.e. QE/CI on or off. OR, can it be something where like it looks like QE/CI is on, but can still get graphical glitches that can mean something is wrong with dsdt implementation? I hope this makes sense.
Basically, my issue is that every now and then my display color profile isn't loaded @ login.
