Abstract
A novel method of power management is provided in a computer system having a network interface module including a buffer memory and a MAC block. The method includes determining whether the system is inactive during a predetermined time period. If so, activity of the MAC block is checked. If the MAC block is idle, the status of the buffer memory is determined. The system is placed into a power-down mode if the buffer memory is empty.
