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 file
2: 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/Contents
and handOff+5GHz support with this wireless_bcm9435-110-v4.0c.command
3: your display, it is LCD TN, or IPS?

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.
