Hello,
since the the HD3000 chips do work pretty much OOB in 10.7 it's no real handicap to ignore one's powerful discrete GPU for OSX. But one major downside is the vast amount of precious battery power being wasted by the turned on, but unusable NVIDIA GPU in an optimus setup.
i have been trying to disable the NVIDIA GPU by copying the respective function from the SSDT into the DSDT in order to call it somewhere, but it turns out to be rather tricky for my particular setup. it seems the DSDT/SSDT are widely programmed in a whole different approach than most of the old ones for which i saw some results on this matter.
is there anyone who has experience in this and who would be willing to point me in the right direction here?
it's an i7-2670QM built into a dell vostro 3750 with a hd3000 and the gt 525m.
i'm considering downgrading the bios, since the version distributed by dell is older than the one mine was shipped with. and the dsdt on this one are pretty buggy.
thanks in advance for any hints
