  • Resetting time-out for automatic power-off of a notebook computer upon placement of a stylus in a storage location
    Patent number: 7036026
    Abstract: A notebook computer has a display screen adapted to interact with a stylus and a storage location for storing the stylus when the stylus is not in use. The notebook computer also has a power control means for powering on the notebook computer upon removal of the stylus from the storage location and for powering off the notebook computer upon replacement of the stylus into the storage location. The power control means resets a time-out for automatic power-off to the notebook computer to a default value upon replacement of the stylus into the storage location. The power control means also increases a time-out for automatic power-off of the notebook computer whilst the stylus is removed from the storage location. The notebook computer may also include a power on-off switch and the power control means may also power on the notebook computer when the power on-off switch is operated. The power on-off switch when operated to power on the notebook computer may also release the stylus from the storage location.
