1. An information processing apparatus comprising:
- a main body;
a main display attached to the main body, the main display being movable between an open position and a closed position;
a power supply controller configured to supply operation power;
a sub-display provided on a surface portion of the main body, the sub-display having a display surface exposed irrespective of whether the main display is set to the open position or the closed position, the sub-display being configured to be supplied with operation power from the power supply controller irrespective of whether the apparatus is set in a powered-on state or a powered-off state;
a clock device provided in the main body, that measures time and is configured to be supplied with operation power from a dedicated battery irrespective of whether the apparatus is set to the powered on state or the powered off state;
a controller provided in the main body, configured to display, on the sub-display, clock information indicative of time, the controller including a counter which counts up a present time set therein to generate values of the time displayed on the sub-display, the counter being configured to be supplied with operation power from the power supply controller irrespective of whether the apparatus is set in the powered-on state or the powered-off state;
means for sending, to an operating system which is executed by a central processing unit within the main body, a request for changing of the present time or time zone, in accordance with a user'"'"'s operation;
means for detecting, by using a resident program which is executed by the central processing unit, that the operating system changes system time in accordance with the request for changing of the present time or the time zone, and for acquiring changed system time from the operating system when the change of the system time is detected, the system time being managed by the operating system and being displayed on the main display; and
means for performing, by using a BIOS program which is executed by the central processing unit, a process for setting, in the counter, the changed system time which is acquired by the resident program, thereby changing the present time displayed on the sub-display to synchronize the present time displayed on the sub-display with the changed system time being displayed on the main display.

5. A method of controlling display of clock information of apparatus, the apparatus including a main body, a main display attached to the main body, a sub-display provided on a surface portion of the main body, the main display being movable between an open position and a closed position, the sub-display having a display surface exposed irrespective of whether the main display is set to the open position or the closed position, the apparatus further including a power supply controller to supply operation power, a clock device provided in the main body, and a controller provided in the main body, configured to display, on the sub-display, clock information indicative of time, the controller including a counter which counts up a present time set therein to generate values of the time displayed on the sub-display, the method comprising:
-
supplying, by the power supply controller, operation power to the sub-display irrespective of whether the apparatus is set in a powered-on state or a powered-off state; supplying, by the power supply controller, operation power to the counter irrespective of whether the apparatus is set in the powered-on state or the powered-off state; sending, to an operating system which is executed by a central processing unit within the main body, a request for changing of the present time or time zone, in accordance with a user'"'"'s operation; detecting, by using a resident program which is executed by the central processing unit, that the operating system changes system time in accordance with the request for changing of the present time or the time zone, and for acquiring changed system time from the operating system when the change of the system time is detected, the system time being managed by the operating system and being displayed on the main display; and performing, by using a BIOS program which is executed by the central processing unit, a process for setting, in the counter, the changed system time which is acquired by the resident program, thereby changing the present time displayed on the sub-display to synchronize the present time displayed on the sub-display with the changed system time being displayed on the main display. - View Dependent Claims (6)
