The present invention comprises the steps of: detecting a change in a power control signal (e.g., a CPU internal clock control signal, a supply clock control signal to a CPU from the outside, an interrupt signal relative to a CPU (e.g., an CPU SMI# signal (CPU system management interrupt signal)), or a low power control signal to each component) and storing the result of the detection in a storage device, wherein the power control signal represents a control instruction associated with the power consumption to a component of a computer; and periodically measuring either a first signal concerning the power consumption by a specific computer component or a second signal concerning power consumed by the entire computer, or both the first and the second signals, and storing the result of the measurement in the storage device. The computer components are internal computer components, including a battery, but are also such externally connected components as a CD-ROM, an FD drive or a docking station.
