Abstract

A method and a system for charging management are applied in an electronic device. The system includes a sensing unit, a detecting unit, a signal output unit, a receiving unit and a processing unit. By the method, when the sensing unit senses an external power source inputted to the electronic device, the detecting unit detects a current electric quantity of a battery of the electronic device. The processing unit actuates the signal output unit to provide an operating interface for a user to issue a command through a hot key or an application program selection control window. After the receiving unit receives the command from the user, a required charging mode is activated according to the user'"'"'s requirement. Therefore, problems resulted from battery removal such as inconvenience and failure of an uninterruptable power mechanism are solved, and a battery charging frequency is reduced to prolong the battery lifetime.

Claims

1. A method for charging management, applicable in an electronic device having a display screen and an input interface, so as to perform a charging process on the electronic device via a system for charging management, the method comprising the steps of:

(1) having the system actuate a light indicator or output an application program selection control window through the display screen when an external power source is inputted to the electronic device, so as to allow a user to determine whether a keystroke battery charging mode is to be activated to perform the charging process on the electronic device, if yes, proceeding to step (2), or if no, proceeding to step (4);

(2) allowing the user to determine whether a charging command is to be issued via the application program selection control window or the input interface of the electronic device according to a practical requirement, if yes, proceeding to step (4), or if no, proceeding to step (3);

(3) having the system temporarily subject a battery of the electronic device to a non-charging status, and allowing the user to return to step (2) and determine whether the charging process is to be performed depending on a remaining status of an electric quantity of the battery, if yes, proceeding to step (4), or if no, maintaining the electronic device in the non-charging status; and

(4) performing the charging process on the battery of the electronic device via the external power source.

2. The method of claim 1, wherein the electronic device is one selected from of the group consisting of laptop computer, personal digital assistant (PDA), digital camera, digital video camera, mobile phone and portable television.

3. The method of claim 1, wherein the method is applied to a Microsoft Windows operating system.

4. The method of claim 1, wherein the method utilizes a basic input/output system-embedded controller (BIOS-EC) to control the charging process and is applicable to a non-Microsoft Windows operating system.

5. The method of claim 1, wherein the input interface of the electronic device is a hot key.

6. The method of claim 1, wherein the external power source is a public alternating current source.

7. A system for charging management, applicable in an electronic device having a display screen and an operating interface, the system comprising:

a sensing unit for determining whether there is an external power source inputted to the electronic device, if yes, the sensing unit outputting a power source input signal;

a detecting unit for detecting a current electric quantity of a battery of the electronic device when the detecting unit receives the power source input signal, and for outputting a detection result;

a signal output unit for actuating a light indicator or outputting an application program selection control window comprising the detection result of the electric quantity of the battery through the display screen, so as to allow a user to determine whether a keystroke battery charging mode is to be activated;

a receiving unit for receiving a command inputted from the user to actuate associated functional components; and

a processing unit for monitoring operating procedures of the system.

8. The system of claim 7, wherein the electronic device is one selected of the group consisting of laptop computer, personal digital assistant (PDA), digital camera, digital video camera, mobile phone and portable television.

9. The system of claim 7, wherein the processing unit is a basic input/output system-embedded controller (BIOS-EC).

10. The system of claim 7, wherein the receiving unit is adapted to receive a charging command issued from the user through a dialogue window or the operating interface.
