Claims14
A power management method for use in an electronic device, comprising the steps of:
- a) providing a first section which stores volatile data and is capable of entering a low power consumption state;
- b) providing a second section which can automatically and regularly power itself up and down;
- c) providing a power source powering both the first and the second sections;
- d) powering the first section up from the low power consumption state to a powered up state, automatically;
- and
- e) assessing, using a power management algorithm operating on the first section in the powered up state to assess whether both the first and the second sections should be taken to a low power consumption state.
An electronic device programmed to perform a power management method, in which the device comprises a first section which stores volatile data and is capable of entering a low power consumption state and a second section which can automatically and regularly power itself up and down, and a power source powering both the first and the second sections;
- wherein the first section powers itself up from a low power consumption state automatically and a power management algorithm then operates to assess whether both the first and the second sections should be taken to a low power consumption state.
