Patent number: 7528577Abstract: An information processor of an electronic apparatus includes a power manager managing power of a secondary battery, and has major functions and a supplementary function. The power manager initiates restriction of the supplementary function, when detected present remaining battery power of the secondary battery is below a threshold. The power manager computes the threshold for the secondary battery or a set operating time for the major functions according to the remaining battery power at the threshold, in accordance with received user input information and power consumption rates corresponding to the major functions. The power manager computes an operating time available for the major functions in accordance with detected remaining battery power of the secondary battery and the power consumption rates corresponding to the major functions.Type: GrantFiled: May 31, 2006Date of Patent: May 5, 2009Assignee: Fujitsu LimitedInventors: Yasushi Hara, Yoshiyasu Nakashima, Satoshi Kazama, Koichi Yokota, Akira Shiba
