Automatic power-up portable electronic device based on time-dependent event

1. A method of controlling a portable electronic device, comprising:

receiving a power-down command at a processor of said portable electronic device;

determining, at said processor, an automatic power-up date and time based on an earliest one of a next preset power-up date and time and a next time-dependent event reminder; said time-dependent event reminder occurring prior to an associated time-dependent event; said time-dependent event occurring before or after said next preset power-up date and time;

generating, on an output device of said portable electronic device, an output notification indicating said automatic power-up date and time if said next-time dependent event reminder is earlier than said preset power-up date and time;

entering said portable electronic device into a power-down state;

monitoring, via said processor, a date and time; and

automatically powering up said device at the automatic power-up date and time.

2. The method according to claim 1 , wherein said output notification comprises providing an indication of the basis for the automatic power-up date and time prior to entering said power-down state.

3. The method according to claim 1 , wherein the output notification comprises displaying said indication on a display of the portable electronic device.

4. The method according to claim 1 , wherein receiving the power-down command comprises receiving a power-down command from one of a power-down button on the portable electronic device and a preset power-down setting on the device.

5. The method according to claim 1 , comprising presetting a power-down/power-up setting on the device prior to said receiving.

6. A portable electronic device comprising:

a housing;

a display mounted within the housing;

a user input mounted within the housing;

a memory mounted within the housing;

a microprocessor within the housing and connected to the memory, the user input and the display for controlling the display; and

an application for execution by the microprocessor; said application configured for receiving a power-down command, and further configured for determining an automatic power-up date and time based on an earliest one of a next preset power-up date and time and a next time-dependent event reminder; said time-dependent event reminder occurring prior to an associated time-dependent event; said time-dependent event occurring before or after said preset power-up date and time;

said application further configured for generating an output notification indicating said automatic power-up date and time if said next-time dependent event reminder is earlier than said preset power-up date and time;

said application further configured for entering said portable electronic device into a power-down state and monitoring a date and time; said application further configured for automatically powering up at the automatic power-up date and time.

7. The portable electronic device according to claim 6 , wherein the application is further configured for displaying an indication of the basis for the automatic power-up date and time on the display, prior to entering the power-down state.

8. The portable electronic device according to claim 6 , further comprising an output device for emitting a notification upon automatically powering up if the automatic power-up date and time is based on a time-dependent event reminder time.

9. A computer program product for controlling a portable electronic device, the computer program product comprising a computer-readable medium having computer-readable code embodied therein for:

receiving a power-down command at a processor of said portable electronic device;

determining, at said processor, an automatic power-up date and time based on an earliest one of a next preset power-up date and time and a next time-dependent event reminder;

said time-dependent event reminder occurring prior to an associated time-dependent event; said time-dependent event occurring before or after said next preset power-up date and time;

generating, on an output device of said portable electronic device, an output notification indicating said automatic power-up date and time if said next-time dependent event reminder is earlier than next preset power-up date and time;

entering said portable electronic device into a power-down state;

monitoring, via said processor, a date and time; and

automatically powering up said device at the automatic power-up date and time.

10. The computer program product according to claim 9 , comprising computer-readable code embodied therein wherein said output notification provides an indication of the basis for the automatic power-up date and time of the portable electronic device, prior to entering the power-down state.
