I spend a great deal of time myself attempting to figure out the u43jc dsdt, and I was able to find the _PS0 and _PS3 methods.

Since _PS3 is the method for powering off devices, and it was the only occurrence of _PS3 in the entire DSDT.dsl, I figure this is correct.

(It appears at \_SB.PCI0.RP00.VGA). I have no idea if this is right or not, but this is the best I can do.

I also attached the isolated _PS3 method. I looked through it myself, and was unable to find any discernible method that would shut off the GPU...

Any help would be greatly appreciated, I am willing to try test commands posted.
