Having trouble with a SMC reset I'm having trouble with my built in iSight and I'm trying to reset the SMC. My MBP has a non-removable SMC, so the instructions ask me to press CMD-SHIFT-ALT-POWER at the same time, release it at the same time and then press the power button to power on the machine.

Trouble is that, the machine power ons when I press CMD-SHIFT-ALT-POWER and I dont think that resets the SMC. What should I be doing to correct this?
That is the incorrect key combination. You are pressing Command instead of Control.

To reset the SMC on portables with a builtin battery, press (left side):

ShiftControlOption + Power Button

Subsequently, release them at the same time. Then power on your computer.
