No you want no power to the laptop at all when you do it. Did you leave it plugged in the first time?

I dunno what to tell you, sorry. I had the exact same problem pop up after reinstalling and it fixed things when I did the NVRAM reset. There really is no more to it than shutdown, unplug, remove battery, and hold the power button down for 5 or more seconds. Then plug in battery and reboot.

Maybe someone else has other suggestions? Good luck!

It really should fix it... it's just something that happens if you update and specifically install the EFI patch, then reinstall the OS. Effin' Apple :p
