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.
Claims8
An electronic device, comprising:
- a rechargeable battery;
- a wireless communication unit that becomes operable in response to a supply of power to performs communication with another device;
- an operation unit that accepts an operation performed by a user;
- a power-on unit that performs a power-on to supply power to the wireless communication unit if a predetermined operation is accepted by the operation unit;
- a charging unit that pre-charges the rechargeable battery with a first current if a voltage of the rechargeable battery is less than a first value, and quickly charges the rechargeable battery with a second current, which is larger than the first current, if the voltage of the rechargeable battery is equal to or greater than the first value;
- a disabling unit that disables the performance of the power-on if the predetermined operation is detected while the power-on is not performed when the voltage of the rechargeable battery is less than the first value;
- and
- a notification unit that notifies the user that the performance of the power-on is disabled when the rechargeable battery is being charged with the first current.
A power-on status notification method in an electronic device, the electronic device including a rechargeable battery, a wireless communication unit that becomes operable in response to a supply of power to perform communication with another communication device, and an operation unit that accepts operation done by a user, said method comprising:
- an operation detection step of detecting a predetermined operation;
- a power-on step of performing a power-on to supply power to the wireless communication unit if the predetermined operation is detected;
- a charging step of pre-charging the rechargeable battery with a first current if a voltage of the rechargeable battery is less than a first value, and quickly charging the rechargeable battery with a second current, which is larger than the first current, if the voltage of the rechargeable battery is equal to or greater than the first value;
- a disabling step of disabling the power-on if the predetermined operation is detected while the power-on is not performed when the voltage of the rechargeable battery is less than the first value;
- and
- a notification step of notifying the user that the performance of the power-on is disabled when the rechargeable battery is being charged with the first current.
