This thread is getting so vague that I dont know if we are talking about the 200 300 400 or NG.
Anyway the 400 had two switches above the P3 seat that switched off the performance management computer but the engines were still connected via the FADEC, or was that the 300?. As far as I am aware if you had a total electrical failure then the engines continued to turn so the FADEC/PMC was more for fine tuning than an absolute necessity.
I don't know how the NG is connected but if we get back to the basic question, how do you get back on the ground if the engines are out of control? I don't know the scenario he has in mind but don't forget that pulling the fire handles on a 737 will still shut off the fuel and the engines will shut down. I know it is not an ideal plan but if all else fails then it might help to get the aircraft down given a long enough runway and a lot of luck. Perhaps if the questioner can be more specific then he may get a better answer.
