Electronic apparatus and method for changing an attachment state of a battery pack

An electronic apparatus in which a battery device is to be attached, the electronic apparatus comprising:

• a first calculator that calculates a first accumulated time during which the battery device feeds power to the electronic apparatus while being attached to the electronic apparatus in a first attachment state in which a first surface of the battery device faces a reference surface provided in the electronic apparatus;
• a second calculator that calculates a second accumulated time during which the battery device feeds power to the electronic apparatus while being attached to the electronic apparatus in a second attachment state in which a second surface of the battery device faces the reference surface, the second surface being different from the first surface;
• and
• an instructing unit that provides an instruction to change an attachment state of the battery device when a difference between the first accumulated time and the second accumulated time exceeds a given time.

A system comprising:

• an electronic apparatus including a processor and a memory coupled to the processor;
• and
• a battery device that includes a chassis with a first surface and a second surface and feeds power to the electronic apparatus when the battery device is attached to the electronic apparatus in any of a first attachment state in which the first surface faces a reference surface provided in the electronic apparatus and a second attachment state in which the second surface faces the reference surface, the second surface being deferent from the first surface, and
• wherein the processor executes a process including:
• calculating a first accumulated time during which the battery device feeds power to the electronic apparatus while being in the first attachment state;
• calculating a second accumulated time during which the battery device feeds power to the electronic apparatus while being in the second attachment state;
• and
• providing an instruction to change an attachment state of the battery device when a difference between the first accumulated time and the second accumulated time exceeds a given time.

A non-transitory computer-readable recording medium having stored therein a program for causing a computer to execute a process for controlling an electronic apparatus in which a battery device is to be attached, the process comprising:

• calculating a first accumulated time during which the battery device feeds power to the electronic apparatus while being attached to the electronic apparatus in a first attachment state in which a first surface of the battery device faces a reference surface provided in the electronic apparatus;
• calculating a second accumulated time during which the battery device feeds power to the electronic apparatus while being attached to the electronic apparatus in a second attachment state in which a second surface of the battery device faces the reference surface, the second surface being different from the first surface;
• and
• providing an instruction to change an attachment state of the battery device when a difference between the first accumulated time and the second accumulated time exceeds a given time.
