This set of patches/makefile can be used to patch your Lenovo Y50-70 DSDT/SSDTs. There are also post install scripts that can be used to create and install the kexts the are required for this laptop series.
Although older versions of the repo had scripts to automate patching of DSDT/SSDTs, the current version does it all via config.plist hotpatching and SSDT-HACK.
