1. A computer system comprising:
- a battery unit;
a charging unit which outputs a charging current to the battery unit; and
a first temperature compensating unit which selectively adjusts the level of the charging current so that the temperature of the charging unit is substantially within a predetermined range, wherein the charging unit comprises;
a switching part electrically coupled to the battery unit; and
a switching controller which controls the switching part so that a voltage of the battery unit reaches a predetermined target value.
