Abstract
An arrangement, system, and method to allow a computer system to have a normal operating mode with full display capability and a low-power operating mode with reduced display capability is provided. The computer system automatically switches to the low-power operating mode from the normal operating mode following a programmable period of inactivity. While display data is retrieved from an external DRAM in the normal operating mode, display data is retrieved from an internal SRAM in the low-power operating mode. The computer system switches back to the normal operating mode when one of the predetermined activities is detected.
