Hello C Adams, it is very true I share Aaron's grip, you have to use an Original Apple keyboard with cable to be able to restart the SMC + PRAM + and + NVRAM, and any on the iMac or any Mac, greetings To reset your NVRAM, you use the very same strategy you once used to reset PRAM. Hold these keys until the computer restarts and you hear the startup sound for a second time. I used the PRAM reset and now when I press the power button I hear the laptop try to turn on but it doesn't have a chime and only stays a black screen with the front power light on. SMC Reset Won't Work on Macbook Pro Retina mid-2012 keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time
