Abstract
Disclosed is a portable information processing apparatus that can detect a remaining battery charge level quickly and comparatively accurately while it eliminates the influence of noise that can be caused when a remaining battery charge is to be detected, that can prevent a battery pack from being mistakenly identified as abnormal by delaying the timing for detecting the unbalanced state of the voltages at each voltage row, which can occur temporarily during the charging of a secondary battery pack when a plurality of cells are connected in series and parallel, that changes power control procedures for each different suspend mode so that it can control with no problem the supply of power to a unit, such as a printer unit, that consumes a large current, even when a remaining battery charge is comparatively low and that can match the phases of the individual units to ensure rebooting is actually performed when a power supply SW is turned on or off at an arbitrary time.
