  • Idle detection system
    Patent number: 5355501
    Abstract: A method and apparatus for idle detection in a computer system. The operating system of the computer includes an idle kernel which performs idle detection to detect idle states when application program processes are idle. To check for idle states, the idle kernel monitors operating system functions which are typically used by application programs when they are otherwise idle. The operating system includes an idle driver which controls idle operations in response to idle states detected by the idle monitor. The idle driver causes the system to enter the power saving mode with frequent, sometimes short idle intervals.
