Delayed power-on function for an electronic device
A delayed power-on function for an electronic device is disclosed. A charging unit charges a rechargeable battery with a pre-charge current when a voltage of the rechargeable battery is less than a voltage threshold value and with a current larger than the pre-charge current when the voltage of the rechargeable battery is greater than the voltage threshold value. A disabling unit can disable power-on when the voltage of the rechargeable battery is less than the voltage threshold value. A user may also be notified when power-on is disabled.
1. An electronic device comprising:
a rechargeable battery;
a charging unit operable to:
charge the rechargeable battery with a pre-charge current when a voltage of the rechargeable battery is less than a voltage threshold value; and
charge the rechargeable battery with a current that is larger than the pre-charge current, when the voltage of the rechargeable battery is equal to or greater than the voltage threshold value;
a disabling unit operable to disable power-on when the voltage of the rechargeable battery is less than the voltage threshold value; and
a notifying unit operable to provide a power-on disabled notification, if the rechargeable battery is being charged with the pre-charge current and the pre-charge current is equal to or greater than a current threshold value.
2. The electronic device according to claim 1 , further comprising a display unit comprising a screen and operable to display the power-on disabled notification on the screen.
3. The electronic device according to claim 1 , wherein the notifying unit is further operable to provide a battery charging notification to indicate that the rechargeable battery is being charged with the pre-charge current.
4. The electronic device according to claim 1 , wherein the notifying unit does not provide the power-on disabled notification, if the pre-charge current is less than the current threshold value.
5. The electronic device according to claim 4 , further comprising preventing display of the power-on disabled notification on a screen of a display unit by not turning power on to the display unit.
6. The electronic device according to claim 1 , further comprising displaying a wait notification until power-on is enabled.
7. The electronic device according to claim 1 , further comprising providing a battery charging notification and/or providing the power-on disabled notification via sound.
8. A method for charging an electronic device, the method comprising:
charging a rechargeable battery with a pre-charge current when a voltage of the rechargeable battery is less than a voltage threshold value; and
charging the rechargeable battery with a current that is larger than the pre-charge current, when the voltage of the rechargeable battery is equal to or greater than the voltage threshold value;
disabling power-on when the voltage of the rechargeable battery is less than the voltage threshold value; and
providing a power-on disabled notification, if the rechargeable battery is being charged with the pre-charge current and the pre-charge current is equal to or greater than a current threshold value.
9. The method for charging an electronic device according to claim 8 , further comprising displaying the power-on disabled notification.
10. The method for charging an electronic device according to claim 8 , further comprising providing a battery charging notification to indicate that the rechargeable battery is being charged with the pre-charge current.
11. The method for charging an electronic device according to claim 8 , further comprising not providing the power-on disabled notification, if the pre-charge current is less than the current threshold value.
12. The method for charging an electronic device according to claim 11 , further comprising preventing displaying of the power-on disabled notification on a screen of a display unit by not turning power on to the display unit.
13. The method for charging an electronic device according to claim 8 , further comprising providing the power-on disabled notification and/or the battery charging notification via sound.
14. A non-transitory computer-readable medium for an electronic device, the computer-readable medium comprising program code for:
charging a rechargeable battery with a pre-charge current when a voltage of the rechargeable battery is less than a voltage threshold value; and
charging the rechargeable battery with a current that is larger than the pre-charge current, when the voltage of the rechargeable battery is equal to or greater than the voltage threshold value;
disabling power-on when the voltage of the rechargeable battery is less than the voltage threshold value; and
providing a power-on disabled notification, if the rechargeable battery is being charged with the pre-charge current and the pre-charge current is equal to or greater than a current threshold value.
15. The non-transitory computer-readable medium according to claim 14 , further comprising program code for displaying the power-on disabled notification.
16. The non-transitory computer-readable medium according to claim 14 , further comprising program code for providing a battery charging notification to indicate that the rechargeable battery is being charged with the pre-charge current.
17. The non-transitory computer-readable medium according to claim 14 , further comprising program code for not providing the power-on disabled notification, if the pre-charge current is lower than the current threshold value.
18. The non-transitory computer-readable medium according to claim 17 , further comprising program code for preventing displaying of the power-on disabled notification on a screen display unit by not turning power on to the screen display unit.
19. The non-transitory computer-readable medium according to claim 14 , further comprising program code for providing a battery charging notification and/or providing the power-on disabled notification via sound.
