Patent ID: 8325051

Claim:
An information processing apparatus comprising: a rechargeable battery that is electrically connected to a charging electric power generating device; a switch that is disposed to electrically connect the charging electric power generating device and the rechargeable battery; an electric power measuring unit that measures electric power produced by the charging electric power generating device; a charge controller that controls the switch to be turned OFF when the electric power measured by the electric power measuring unit is smaller than a first electric power threshold; and an indicator, wherein the charge controller operates to: (a) turn OFF the indicator and turn ON the switch when the electric power is equal to or larger than the first electric power threshold and smaller than a second electric power threshold that is higher than the first electric power threshold while a charging operation is not completed; (b) turn ON the indicator and the switch when the electric power is equal to or larger than the second electric power threshold while the charging operation is not completed; and (c) turn OFF the indicator and the switch when the charging operation is completed.
