howoarang Posted January 10, 2016 Author Share Posted January 10, 2016 problems may be with this: 1: my SSDT.aml is for CPU i7-4800mq, yours is i7-4810mq I think, so try it without this file2: to work my wifi Dell Wireless 1550 I must insert device and vendor ID to Info.Plist here: /System/Library/Extensions/IO80211Family.kext/Contents/PlugIns/AirPortBrcm4360.kext/Contentsand handOff+5GHz support with this wireless_bcm9435-110-v4.0c.command3: your display, it is LCD TN, or IPS? wireless_bcm94352-110-v4.0c.command.zip Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted January 10, 2016 Moderators Share Posted January 10, 2016 Add fakeID for full GPU graphics and install FakePCI + FakePCIID_Intel_HD_Graphics key>FakeID IntelGFX 0x04128086 Link to comment Share on other sites More sharing options...
howoarang Posted January 10, 2016 Author Share Posted January 10, 2016 I tried this method day last day. I got full GPU with Intel HD4600, but with this method I lost HDMI and DP video output and I needed it, because usually work on external 24"LCD display.

Moderators Jake Lo Posted January 10, 2016 Moderators Share Posted January 10, 2016 Hmm, I'll need to test this config on my M6800 and see if it's the same behavior. Do you have to plug in power adapter when waking up the system? I get a black or blank screen if it's not plugin in prior to waking it up. Edit: Try ACPIPoller.kext with Rehabman's LIDP patch, see if sleep with LID works. Link to comment Share on other sites More sharing options...
howoarang Posted January 10, 2016 Author Share Posted January 10, 2016 If I try to wake up on battery power, it goes to hibernate mode I think and from this mode laptop can't be wake up. I must cancel hibernate mode during boot in Clover.If I try to wake up on AC power adapter, wake up works normally. Link to comment Share on other sites More sharing options...
