it seems that the older AppleACPIPlatform.kext supplied by EDP and the boot packs is failing on 10.9.2
causing sleep issues for some and broken restarts.
personally tested by me on a D630 nvidia many other models are also affected. solution is to use the supplied 10.9.2 version located in System/Library/Extensions version 2.0 dated 1/16/14 i have attached it incase it has been removed from S/L/E you can add it to and run it from E/E if it has been removed from S/L/E run a my fix quick afterwords.
