Abstract

An electronic apparatus includes an authentication unit that executes an authentication process for authenticating a battery connected to the electronic apparatus, a holding unit that holds a value representing a result of the authentication process, wherein the value held by the holding unit is deleted in a case where the battery is removed from the electronic apparatus, or in a case where a voltage of the battery is equal to or less than a predetermined value, and a control unit that performs control to determine whether to cause the authentication unit to execute the authentication process according to the value held by the holding unit.

Claims

1. An electronic apparatus comprising:

an authentication unit that executes an authentication process for authenticating a battery connected to the electronic apparatus;

a holding unit that holds a value representing a result of the authentication process, wherein the value held by the holding unit is deleted in a case where the battery is removed from the electronic apparatus, or in a case where a voltage of the battery is equal to or less than a predetermined value; and

a control unit that performs control to determine whether to cause the authentication unit to execute the authentication process according to the value held by the holding unit.

2. The electronic apparatus according to claim 1, wherein, in a case where the authentication process results in failure, the holding unit holds a value different from an initial value.

3. The electronic apparatus according to claim 1, wherein, in a case where the value held by the holding unit is a value different from an initial value, the control unit determines that the authentication process results in failure.

4. The electronic apparatus according to claim 3, further comprising a display unit,

wherein, in a case where it is determined that the authentication process results in failure, the control unit prevents information about authentication of the battery from being displayed on the display unit.

5. The electronic apparatus according to claim 1, wherein, in a case where the authentication process results in success, the holding unit holds a value different from an initial value.

6. The electronic apparatus according to claim 1, wherein, in a case where the value held by the holding unit is a value different from an initial value, the control unit causes the authentication unit not to execute the authentication process.

7. The electronic apparatus according to claim 6, further comprising a display unit,

wherein, in a case where it is determined that the authentication process results in success, the control unit prevents information about authentication of the battery from being displayed on the display unit.

8. The electronic apparatus according to claim 1, wherein, in a case where the authentication process is executed by the authentication unit, the holding unit holds a value different from an initial value.

9. The electronic apparatus according to claim 1, wherein, in a case where the value held by the holding unit is a value different from an initial value, the control unit causes the authentication unit not to execute the authentication process.

10. The electronic apparatus according to claim 9, further comprising a display unit,

11. A method comprising:

causing an authentication unit to execute an authentication process for authenticating a battery connected to the electronic apparatus;

causing a holding unit to hold a value representing a result of the authentication process, wherein the value held by the holding unit is deleted in a case where the battery is removed from the electronic apparatus, or in a case where a voltage of the battery is equal to or less than a predetermined value; and

performing control to determine whether to cause the authentication unit to execute the authentication process according to the value held by the holding unit.

12. A non-transitory storage medium that stores a program for causing a computer to execute a method, the method comprising:

causing an authentication unit to execute an authentication process for authenticating a battery connected to the electronic apparatus;

causing a holding unit to hold a value representing a result of the authentication process, wherein the value held by the holding unit is deleted in a case where the battery is removed from the electronic apparatus, or in a case where a voltage of the battery is equal to or less than a predetermined value; and

performing control to determine whether to cause the authentication unit to execute the authentication process according to the value held by the holding unit.
