Activation system

An activation system is applied to a computer apparatus. An activation signal is received by the computer apparatus to implement a booting action. The system comprises an external power adapter and a detection unit. An external power is received by the external power adapter. The external power then is provided to the computer apparatus. Meanwhile, a power supply signal then is generated by the external power adapter. The power supply signal is detected by the detection unit. The activation signal is outputted by the detection unit after detecting the power supply signal, so as to boot the computer apparatus through the external power.

FIELD OF THE INVENTION

The present invention relates to an activation system, and more particularly to the activation system that controls a computer to implement booting by detecting a power supply signal of an external power.

BACKGROUND OF THE INVENTION

Referring toFIG. 1, a block diagram illustrates a conventional computer apparatus. The computer apparatus is booted or shut down through a button to control the main power supply. As shown inFIG. 1, the computer apparatus includes a power supplier11, a main system12, an interface controller13, a keyboard14, a mouse15and other input/output interface16. The power supplier11includes a button111. The power supplier11could obtain a booting signal through a user pressing the button111. A main power112then is provided to the main system12, the interface controller13, the keyboard14, the mouse15and other input/output interface16, thereby achieving the goal of booting the computer apparatus. In addition, the user presses the button111after the computer is booted to enable the power supplier11to obtain a shut down signal. The power supplier11then is stopped supplying the main power112to the main system12, the interface controller13, the keyboard14, the mouse15and other input/output interface16, thereby achieving the goal of shutting down the computer apparatus.

Referring toFIG. 2, a block diagram illustrates a conventional apparatus for controlling a power supplier21. The apparatus includes a power controller22, a keyboard23, a mouse24and a recognition controller25. The power supplier21generates a power with 5 voltages. The power with 5 voltages is supplied to the power controller22, the keyboard23, the mouse24and the recognition controller25. The recognition controller25is used to detect input signals provided by the keyboard23and the mouse24to determine whether or not the input signals are signals for booting. For instance, the input signals are inputted by pressing some keys of the keyboard23simultaneously or by clicking the mouse24several times. Therefore, the recognition controller25could control the power controller22to output a booting signal to the power supplier21. The power supplier21then is triggered to supply a main power to a main system26of the computer and an interface controller27so as to achieve the goal of booting.

However, the aforesaid conventional techniques must input a booting signal through the user to control the computer apparatus to be booted to cause inconvenience.

The inventor of the present invention based on years of experience from related research and development invents an activation system for a computer to overcome the foregoing shortcomings.

SUMMARY OF THE INVENTION

Accordingly, the object of the present invention is to provide an activation system. More specifically, the computer is controlled to implement the booting by detecting a power supply signal of an external power so as to simplify the booting steps for the computer and increase convenience.

To achieve the aforesaid object, the activation system disclosed by the present invention is applied to the computer for receiving an activation signal to implement booting. The system includes an external power adapter and a detection unit. The computer implements a booting procedure to activate an operating system (OS). The external power adapter could receive the external power and provide the external power to the computer. Meanwhile, the external power adapter then generates the power supply signal. The external power is an operational power for the computer implementing the booting procedure and activating the operating system. The detection unit is used to detect the power supply signal. When the power supply signal is detected, the detection unit then outputs the activation signal to the computer to control the computer to implement the booting. Moreover, when the computer implements the booting, the computer outputs a shutdown signal to the detection unit simultaneously. The detection unit then is controlled to stop detecting.

The external power adapter is electrically connected to an alternating current (AC) power plug to receive AC power. AC power then is converted into the external power with stable voltage. A battery is also disposed in the computer. The power of the battery can be the operational power required for booting the computer. Furthermore, the external power adapter could implement a charging action for the battery through the computer. Additionally, the system further includes a setting switch that is used to set or stop running the detection unit.

Other features and advantages of the present invention and variations thereof will become apparent from the following description, drawings, and claims.
