ABSTRACT:
An apparatus and method for controlling power management enable a computer system to have minimum power consumption during a rest mode. The power management system in the computer system allows the contents of the main memory to be maintained when the system proceeds to the rest mode. The apparatus includes a microcontroller which receives a first operating voltage from the power supply and controls power distribution based on the power management program stored in a BIOS ROM. The microcontroller generates a control signal when the system proceeds to the rest mode. Further included are: a main memory receiving a second operating voltage from the power supply and having a self-refresh function in the rest mode; a memory controller receiving a third operating voltage from the power supply and generating memory control signals supplied to the main memory; and a buffer receiving a second operating voltage from the power supply and located between the main memory and the memory controller for interrupting memory control signal lines in response to a control signal generated by the microcontroller. The microcontroller interrupts the third operating voltage when the buffer is inactivated by the control signal from the microcontroller.
