The 747 has multiple electrical systems and many fall back systems in case something goes wrong.Turning the GENerator CONTrol buttons ON will allow the engines generators to provide electrical power to the system.
I believe all of the procedures and information here to be factual, though it is often overly simplified and not necessarily in the correct order.
When set to OFF, only a few systems will be powered by the battery.
AUTO allows the electrical system to draw the power from the best available power source. Ensure that the Hydraulic DEMAND pump switches are set to OFF. The ELEC ENG CONTROL switches allow the electrical system to operate the engines.
I WILL NOT ANSWER STUPID QUESTIONS THAT ARE ANSWERED ELSEWHERE.
