ABSTRACT:
Two cooling functions are provided: one being reduction in operation speed of a CPU, and the other being rotation of a motor fan. The two cooling functions are selectively used in accordance with a cooling mode set by a user. When a "Quiet" mode is selected by the user, a mode giving a priority to low power consumption is set to make the battery operation time as long as possible. In this case, the motor fan is not rotated and only the CPU operation speed is lowered. On the other hand, when a "Performance" mode is selected by the user, a mode giving a priority to performance is set. In this case, the CPU operation speed is not lowered, and only the motor fan is rotated. The "Performance" mode and "Quiet" mode can be freely set by the user on a setup screen.
