The present invention provides a laptop computer including a keyboard on which keys for data input are arranged. The laptop computer includes a charging device in which a battery pack is charged when a key for data input is pressed. The charging device includes: a current generation unit which generates current when a key is pressed; a current rectification unit which rectifies the current generated by the current generation unit and prevent a countercurrent; a current smoothing unit which smooths the current generated by the current generation unit; one or more battery packs in which the currents from the current generation unit, the current rectification unit, and the current smoothing unit are stored; and a power path control unit which is programmed to supply current to the battery packs. |
