Abstract
The present invention is a method and apparatus for reducing power consumption of a computer system in a suspend mode. When the computer system enters a suspend mode, the main clock is turned off and the internal oscillator is used to refresh the memory. This internal oscillator is designed such that it is only operating when the computer system is in a suspend mode. The internal oscillator is further designed such that during suspend mode, it operates only to properly refresh the memory and enter or exit the suspend mode.
