[0046] Now, the computer device 10 shown in FIG. 2 as a first embodiment will be described. The computer device 10 contains a system unit 11 corresponding to the system unit 2 in the electronic device 1 described above, a power control unit 12 corresponding to the power control unit 3 in the electronic device 1, and a secondary battery 13 , which corresponds to the secondary battery 4 in the electronic device 1, as shown in FIG. 2 .
[0047] In the system unit 11, the arithmetic processor 14 contains a central processing unit (CPU) and a signal transmission circuit called a so-called north bridge, and the signal processor 15 contains a signal transmission circuit called a south bridge. The devices are interconnected by a bus such as a peripheral component interconnect (PCI) bus.
[0048] Also, the system unit 11 contains various semiconductor memories such as random access memory (RAM) and read only memory (ROM), a hard disk drive for recording / reproducing information on a ma...

[0079] Next, a computer device 20 shown in FIG. 6 as a second embodiment of the present invention will be described. Compared with the computer device 10 according to the first embodiment described above, the computer device 20 is mainly different in that, as shown in FIG. 20 has the same or equivalent structure as other parts of the computer device 10 . Therefore, in this embodiment, descriptions of parts that are the same as or equivalent to those of the first embodiment described above are omitted, and in the drawings, they are denoted by the same reference numerals.
[0080] Embodiments exemplified and described hereinafter can be implemented as the same or equivalent in configuration as the computer device 10 according to the first embodiment. Therefore, in these embodiments, descriptions of parts that are the same as or equivalent to those of the first embodiment described above are omitted, and in the drawings, they are denoted by the same reference numerals.

[0089] Next, a computer device 30 shown in FIG. 7 as a third embodiment will be described. As shown in FIG. 7, the computer device 30 is similar in configuration to the computer device 10 shown as the first embodiment.
[0090] In this embodiment, it is assumed that the computer device 30 has a basic structure designed in accordance with the ACPI standard described in the second embodiment. The computer device 30 has a mechanism for switching to the power saving mode when the remaining amount of power of the secondary battery 13 decreases. In many computer devices used in recent years, such a mechanism is provided, and it is premised that a basic input output system (BIOS) and an operating system (OS) installed in the system unit 11 can accept this mechanism.
[0091] This embodiment differs from the computer device 20 explained in the second embodiment in that the power control unit 12 falsely reports not the temperature of the CPU but the remaining amount of power of the se...
