Electronic apparatus
An electronic apparatus includes an expansion unit having a battery. The electronic apparatus includes a controller and a display. The controller performs power management of the battery. The display displays a residual capacity of the battery. The controller controls the display such that the display performs pattern display based on the residual capacity.
1. An electronic apparatus comprising:
an expansion unit that has a first battery;
a first controller that performs power management of the first battery;
a main body that has a second battery;
a second controller that performs power management of the second battery; and
a display that displays a residual capacity of the first and second batteries,
wherein the first controller acquires the residual capacity of the second battery from the second controller, sums up the residual capacity of the first battery and the residual capacity of the second battery, and controls the display such that the display performs pattern display.
2. The electronic apparatus according to claim 1 , wherein:
in a state where an OS of the main body is not active, the first controller acquires the residual capacity of the second battery from the second controller.
