Claim 4:
5. A method for controlling an information processing apparatus that includes control circuitry and an operation unit with a display and switches between a normal mode and an energy-saving mode with less power consumption than the normal mode of the information processing apparatus, the method comprising:
writing change information indicating change of an operation mode of the information processing apparatus in response to switching between the normal mode and the energy-saving mode, into a first device having a first limit to a number of times of writing and into a second device having a second limit to a number of times of writing,
counting the number of times of writing the change information to the first device and the second device,
predicting a life of the first device on a basis of a first count value of the number of times of writing for the first device;
predict a life of the second device on a basis of a second count value of the number of times of writing of the change information for the second device;
diagnosing appropriateness of the first count value used for prediction of the life of the first device and appropriateness of the second count value used for prediction of the life of the second device, when a first increase rate of the first count value or a second increase rate of the second count value exceeds a threshold; and
correct the first count value according to the second count value so that the increase rate of the first count value is equal to or smaller than the threshold, when the increase rate of the first count value exceeds the threshold.
