Abstract
An apparatus is provided comprising a system including one or more electronic components; a power input unit arranged to supply power to the system; and a power management module configured to: detect whether the system is in an abnormal state, and in response to detecting that the system is in the abnormal state, adjust at least one of (i) power supplied from a battery to the system, (ii) the power supplied from the power input unit to the system, and (iii) power supplied from the power input unit to the battery.
Claims17
An electronic device comprising:
- a touch screen;
- a communication circuitry;
- a memory;
- a battery;
- a power input unit;
- a watch-dog timer;
- and
- at least one processor configured to:
- control the power input unit to supply power to the battery, the touch screen and the communication circuitry in a normal operation state;
- control the battery to supply the power to the touch screen and the communication circuitry in an abnormal operation state;
- control the watch-dog timer to monitor whether the at least one processor identifies data within a predetermined time;
- when the at least one processor does not identity the data within the predetermined time, control the watch-dog timer to determine that the at least one processor is in the abnormal operation state;
- and
- in response to determining that the at least one processor is in the abnormal operation state, control the power input unit to block power supplied to the battery, the touch screen and the communication circuitry.

A method comprising:
- controlling a power input unit to supply power to a battery, a touch screen and a communication circuitry in a normal operation state;
- controlling the battery to supply the power to the touch screen and the communication circuitry in an abnormal operation state;
- controlling a watch-dog timer to monitor whether at least one processor identifies data within a predetermined time;
- determining, via the watch-dog timer, when the at least one processor does not identify the data within the predetermined time, that the at least one processor is in the abnormal operation state;
- and
- in response to determining that the at least one processor is in the abnormal operation state, controlling the power input unit to block power supplied to the battery, the touch screen, and the communication circuitry.
