OptionDescription Suspend to RAM The system writes data to memory and shuts everything down while keeping the data alive with a minimum amount of power from the battery. Suspend to disk The system writes data to disk and shuts off completely; no power is used, so no data can be lost. Slow the processor The system is on but not involved in heavy-duty calculations. The processor slows down to a point where it can still handle the users needs, but does not waste energy trying to process data at an unnecessarily high rate. Advanced Power Management Options
