Power management system and method of displaying power management information in a computer
 A computer system capable of providing a visual display of a display power management signaling (DPMS) mode for user selection of different power save modes of operation. The DPMS mode is used to convert a power supply mode to a power save mode in a computer peripheral such as a monitor. The computer system includes a micro-computer installed in the monitor for determining whether the frequency of sync signals are within predetermined bands to set the power save mode, a switching element installed in the computer for controlling the power supply of a predetermined voltage under control of the micro-computer, and a luminance element installed at a predetermined location of a keyboard and powered by the operation of the switching element for providing a visual display of the DPMS mode for user selection of different power save modes of operation.
