I have tried updating from 10.7.2 to 10.7.5 sleepenabler deleting and restoring permissions and not working to me. Just get to start it with-F. I get an error unsupported kernel Fintek chip in the log. I tested with 10.7.3 applesmc.kext for me but neither works. I'll reinstall and see what happens.
I had an fintek 718x generating logs, I removed the plugin from the package(as the package comes with 4 or 5, not all boards have them) and resent the kext with a kext tool. being using 10.7.5 for a while now, all good...
