Ok before I dive into testing platform id's should I try all of these or only the mobile ones? These are categorized as being for Broadwell.

The platform id values that lack an LVDS connector will not likely work with your internal display.
(look at the connector list of each)

UPDATE* My EliteBook 850 G3 arrived today. I did a heart/brain transplant and just moved the SSD over from the G2. I re-patched added a new SMBIOS and everything seems to be working perfectly including wake from sleep. It must be HD 5500 graphics with the G2 and other included laptops. Hopefully the issue will eventually be solved. Do you think it's possible that Apple is phasing out support for HD 5500? I'm moving on and selling the G2. The 850 G3 is a big upgrade with 32GB max ram support and other performance upgrades. Happy holidays and thanks again to you and Sniki for all of the tips and suggestions.
