Hello!
Again I am kindly asking for assistance with DSDT preparing for my Lenovo m57 Core2Duo E8400, 4GB RAM, Radeon hd 5450 512 MB low profile card with DMS-59 single connector (with 2 VGA or 2 DVI splitter cable). A little background: this card was working OOB without custom made DSDT, with Inject ATI in clover, in HP dc7800 sff box. However, in Lenovo m57 it does not, i.e. the card is recognised with Inject ATI, but 5MB of memory and no QE/CI video acceleration. I think the reason might be in how the card is described in HP bios.aml and LENOVO bios.aml (obviously differently) or, perhaps, the way Lenovo manages video memory between internal adapter and PCIe graphics, because there's an option to tweak DVMT in BIOS of Lenovo and no such option in HP dc7800 sff.
Also, starting from OS X 10.11 and onwards, shutdown works ok, restart isn't working (power button should be pushed in order to reboot), sleep is not working.
I would really appreciate your help. I attached the output of RunMe and RunMe IOJones.
