Abstract: A method and system for enhancing the life of a battery within a portable or otherwise battery operated electronic device. The method and system provide user selectable display modes, e.g., from color to monochrome, that can be changed in order to enhance the life of the device's battery. The monochrome display mode can be selected by the user when the battery level is detected below a predefined threshold. In one embodiment, the electronic device is a hand held computer system with a display device. When the battery level is detected as below a preselected level, a message is generated on the computer display screen. The message informs the user that the display mode of the screen can be changed to enhance the battery life. If selected, the display mode can change from color to monochrome thereby saving power because the monochrome display does not utilize a back-lighting element. In one embodiment, color sequential techniques are used to provide a flat panel color display.

Operation G allows the user to browse respective data classified for each sheet label. The new functions of the single-unit input/output pen-tablet device can be intuitively operated by a user not versed in the functions. This consequently mitigates the load of complex input operation which interrupts thinking of the user and which hinders diagnosis mitigated in medical treatment.
