Abstract

A computer system may include a main display and an external display coupled, for example, to the computer system through a universal serial bus digital visual interface link. In response to the detection of an indication of a suspension of the system to a reduced power consumption state, such as the S3 sleeping state, the external display may be automatically repainted. In addition, the current image layers and coordinates may be automatically stored to a frame buffer.
