  • Dynamically controlling a power state of a graphics adapter
    Patent number: 6704879
    Abstract: A computer system includes a power source to provide either alternating current from an electrical outlet or direct current from a battery pack. The system also includes a graphics adapter having a clock device that may be regulated based on a power state of the power source. The clock device of the graphics adapter may be set to a high frequency to provide increased graphics performance when the power source is furnishing alternating current to the system. Alternatively, when the power source is providing direct current, the clock device of the graphics adapter may be set to a lower frequency to conserve power.

  • Alternative power for a portable computer via solar cells
    Patent number: 6445376
    Abstract: A system for prolonging the operational life of a battery-powered laptop or notebook computer. Solar cells are incorporated into the chassis or display screen of a notebook computer so that the solar cells can provide power to any component of the notebook computer and/or help with the charging, powering, and/or regulation of a battery used as a power source. In one embodiment, solar cells are mounted near the light source so that unused light energy from the light source can be captured.
