Abstract
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.
Claims9
An electronic device comprising:
- a battery;
- a charging unit operable to charge the battery in a power-off state;
- a disabling unit operable to disable power-on of the electronic device, if a voltage of the battery is less than a first voltage threshold value and if the battery is being charged in the power-off state;
- and
- a notifying unit operable to:
- provide a power-on disabled notification indicating that the battery has not reached the first voltage threshold, if the power-on is disabled and if the battery is being charged in the power-off state;
- and
- provide a power-on enabled notification, if the voltage of the battery is equal to or greater than the first voltage threshold value and if the battery is being charged in the power-off state, wherein the notifying unit provides the power-on enabled notification while the voltage of the battery is being raised by the charging unit and before the battery has reached a fully charged state.
A method for charging an electronic device, the method comprising:
- disabling power-on of the electronic device when a voltage of a battery of the electronic device is less than a first voltage threshold value;
- providing a power-on disabled notification indicating that the battery has not reached the first voltage threshold, if the power-on is disabled and if the battery is being charged when the electronic device is in a power-off state;
- and
- providing a power-on enabled notification, if the voltage of the battery is equal to or greater than the first voltage threshold value and if the battery is being charged in the power-off state, wherein the power-on enabled notification is provided while the voltage of the battery is being raised and before the battery has reached a fully charged state.
A non-transitory computer-readable medium for an electronic device, the computer-readable medium storing computer-executable program code that when executed performs a method for charging an electronic device, the method comprising:
- disabling power-on of the electronic device when a voltage of a battery of the electronic device is less than a first voltage threshold value;
- providing a power-on disabled notification indicating that the battery has not reached the first voltage threshold, if the power-on is disabled and if the battery is being charged when the electronic device is in a power-off state;
- and
- providing a power-on enabled notification, if the voltage of the battery is equal to or greater than the first voltage threshold value and if the battery is being charged in the power-off state, wherein the power-on enabled notification is provided while the voltage of the battery is being raised and before the battery has reached a fully charged state.
