Sure, you can trigger an SMC reset with the SmcFlasher tool. (1) Grab the appropriate SMC firmware update for your machine from Apple. (1) Locate and extract the SmcFlasher.efi from the firmware update package and tuck it somewhere on your system drive. The Pacifist tool is of great help here. (1) Next boot into an EFI shell such as the one included in the rEFInd boot manager, navigate to where you put the SmcFlasher.efi and run it with the parameters -reset 1 Let's say I put it in a folder named "smc" on the root of the system drive, I would then fs1: cd smc ./SmcFlasher.efi -reset 1 Voila.
