A portable electronic device is provided. The portable electronic device includes a system end and an adapter. The system end provides a trigger signal. The adapter converts an input AC voltage into an output DC voltage and provides the output DC voltage to the system end. When the adapter is connected to the system end, the trigger signal turns on the adapter. When the adapter is disconnected from the system end, the adapter detects an absence of the trigger signal and turns off automatically.

A system and a method for power control are provided. In the present invention, a control switch is disposed in a power adapter, which is turned on/off by a monitoring device disposed in a portable electronic device. As a result, the power inputted into the power adapter can be controlled, and thus the power consumption during the portable electronic being shut down is reduced. In addition, the present invention controls the power providing for a battery according to a detected power on/off signal and the electric quantity of the battery. The control switch is turned off to stop the power adapter from providing power when the electric quantity of the battery reaches a reference value. Therefore, the overheating situation of the portable electronic device or the battery that may shorten their service life because of continuing receiving power can be avoided.

A method and apparatus for displaying real-time messages by a mouse cursor are disclosed. A setting unit sets a trigger condition for an event, and a monitoring unit monitors the event according to the trigger condition and thus generates a monitor result. A determining unit determines whether the event is triggered according to the conditions and the monitor result. When the event is triggered, a displaying unit displays a message on or near a mouse cursor to remind a user of the triggered event.

A radio frequency identification (RFID) security system includes an RFID tag and a portable electronic device. The RFID tag has a user ID code. The portable electronic device has a reader, an identification memory and an identification controller. The reader is used to communicate with the RFID tag and to receive the user ID code. The identification memory is used to store a user password. The identification controller is electrically connected to the reader and the identification memory and is used to compare the user ID code and the user password. When the user ID code is the same as the user password, the identification controller is arranged to transmit an enable signal to grant the access of the portable electronic device.

Radio frequency identification security system and method

A predetermined ID code is set in a server, and a radio frequency identification (RFID) tag is configured on an electronic device. A tag ID code of the RFID tag is received by a reader and then is transmitted to the server. The server is used to compare the tag ID code and the predetermined ID code. When the tag ID code is the same as the predetermined ID code, the server is arranged to transmit an enable signal to grant the access of the electronic device. When the tag ID code is different from the predetermined ID code, the server is arranged to send a disable signal to deny the access of the electronic device.

A security activation method for wireless identification for controlling an electronic device system boot up includes the following steps: receiving a first identification signal, designating a corresponding first identification code as a pre-established account, transmitting a confirmation signal to a wireless transmission device corresponding to the pre-established account, receiving an authorization signal from the device, receiving a second identification signal, and comparing a corresponding second identification code with the pre-established account; if the second identification signal is the same as the pre-established account, determine whether the system accesses a boot buffer inside the electronic device; and having the following corresponding implemented actions: if the system accesses the boot buffer inside the electronic device, the system boots and transitions into operational mode; and if the system doesn't access the boot buffer, the system is shut down and receives an automatic command for system boot.

In a computer-implemented method for debugging keyboard basic input/output system (KB-BIOS) in a development notebook computing system, a serial PS/2 port, that is connected to a KB-BIOS processor and that serves as a communications channel, of the development notebook computing system is coupled to a host computer so as to establish communication between the KB-BIOS and the host computer. Thereafter, a debug command is sent from the host computer to the development notebook computing system via the serial PS/2 port. Subsequently, at the development notebook computing system, the debug command sent by the host computer via the serial PS/2 port is directed to the KB-BIOS processor so as to enable the latter to execute the debug command according to program instructions in a debug engine module that resides in a memory of the KB-BIOS, and to send debug data associated with the development notebook computing system to the host computer via the serial PS/2 port in response to execution of the debug command. In this way, KB-BIOS debugging of the development notebook computing system can proceed without assistance from system BIOS of the development notebook computing system.
