Abstract
A method and apparatus for managing power in a portable information device. The method includes entering a low power consumption state if power of the device drops below a first threshold; and backing up data stored in an internal memory of the device through a network if the power of the device drops below a second threshold that is lower than the first threshold.
Claims17
A method of managing power in a portable information device, the method comprising:
- entering a low power consumption state if power of the device drops below a first threshold;
- and
- backing up data stored in an internal memory of the device through a network if the power of the device drops below a second threshold that is lower than the first threshold.
An apparatus for managing power in a portable information device, the apparatus comprising:
- a backup processor that launches the device into a low power consumption state if power of the device drops below a first threshold, and backs up data stored in an internal memory of the device through a network if the power of the device drops below a second threshold that is less than the first threshold.
An apparatus for managing power of a portable information device that stores user data in a memory, the portable information device having an armored battery and a built-in battery, the apparatus comprising:
- a complex programmable logic device (CPLD) that detects battery power and generates an interrupt signal;
- and
- a central processing unit (CPU) that enters a suspended state or performs data backup in response to the interrupt signal.
