FIG. 1 is a diagram of a computer device according to an embodiment of the invention. Referring to FIG. 1, the computer device 100 includes a processor 110, a switch circuit 120, and a connection port 130. The processor 110 is coupled to the switch circuit 120. The switch circuit 120 is coupled to the connection port 130. In this embodiment, when the computer apparatus 100 is in the sleep mode or the power-off mode, the computer apparatus 100 may determine whether to perform a Wake-up (Wake-up) procedure or a power-on (Boot) procedure by detecting whether the connection port 130 is coupled to an external display cable. Specifically, when the connection port 130 is coupled to an external display cable, the connection port 130 outputs an enable signal to the switch circuit 120, so that the switch circuit 120 enables the processor 110. Therefore, the computer device 100 of the present invention can determine whether to wake up or turn on the processor 110 directly according to the connection status of the connection port 130 and the external display cable, and the user can operate the computer device 100 directly through the wired or wireless mouse or keyboard of the computer device 100.
In this embodiment, the computer device 100 may include a Display (Display), and the Display of the computer device 100 is in an off state. When the connection port 130 is coupled to an external display cable, the processor 110 drives an external display through the connection port 130 and the external display cable. That is, no matter whether the built-in monitor is turned on or not, when the connection port 130 is coupled to the external monitor cable, the computer apparatus 100 can display the computer screen through the external monitor. In other words, the user does not need to wake up or turn on the computer device 100 through the power button. In this embodiment, the user can directly couple the external display cable to the connection port 130, so that the computer device 100 automatically wakes up or turns on the processor 110, and displays the computer screen through the external display. In addition, the computer device 100 of the present invention is not limited to include a display. In an embodiment, the computer apparatus 100 may not have a built-in display, and when the connection port 130 is coupled to an external display cable, the computer apparatus 100 may display a computer screen through the external display.
The computer device 100 may be a Notebook computer (Notebook computer), Desktop computer (Desktop computer), Tablet computer (Tablet computer), or the like. The Processor 110 may be a Central Processing Unit (CPU), a System On Chip (SOC), or other Programmable general purpose or special purpose Microprocessor (Microprocessor), a Digital Signal Processor (DSP), a Programmable controller, an Application Specific Integrated Circuit (ASIC), a Programmable Logic Device (PLD), other similar processors, or a combination thereof.

The switch circuit 120 receives the enable signal output from the connection port 130, and wakes up or activates the computer device 100 according to the enable signal. The switch circuit 120 may be a power button of a computer device to wake up or activate the computer device 100. The connection Port 130 may be a High Definition Multimedia Interface (HDMI) connection Port, a Video Graphics Array (VGA) connection Port, or a Display Port (DP) connection Port.
FIG. 2 is a diagram of a computer apparatus according to another embodiment of the invention. Referring to fig. 2, the computer device 200 includes a processor 210, a switch circuit 220, a connection port 230, and a display 240. The processor 210 is coupled to the switch circuit 220 and the display 240. The connection port 230 is coupled to a display 240. In the present embodiment, the computer device 200 may be, for example, a notebook computer, and the display 240 is built in the computer device 200. For example, when the computer apparatus 200 is in a sleep state or a power-off state, the display 240 of the computer apparatus 200 is also in a power-off state. For a notebook computer, the display 240 and the main body of the computer apparatus 200 are closed. Moreover, when the connection port 230 of the computer apparatus 200 is coupled to an external display cable 330, the connection port 230 can output an enable signal to the switch circuit 220, so that the switch circuit 220 executes a wake-up program or a boot program on the processor 210. At this time, when the computer apparatus 200 is awakened or turned on, the processor 210 may be coupled to the external display 340 through the connection port 230 and the display cable 330, and the processor 210 may drive the external display 340 to display a computer screen (e.g., an operation program screen).
In other words, when the computer device 200 is in the sleep state or the power-off state, the user does not need to open or power on the built-in display 240. After the user simply inserts the display cable 330 into the connection port 230 of the computer device 200, the computer device 200 automatically wakes up or starts the processor 210 to operate the operating system. In addition, the computer device 200 can directly provide the display data to the external display 340 through the connection port 230 and the display cable 330, so as to display the computer screen on the external display 340 in real time. Therefore, the computer apparatus 200 of the present embodiment can provide a convenient wake-up function or power-on function, and the computer apparatus 200 of the present embodiment can directly provide a display function through the external display 340 no matter whether the built-in display 240 is turned on or not.
In addition, regarding other technical features and implementations of the processor 210, the switch circuit 220 and the connection port 230 of the present embodiment, sufficient teachings, suggestions and implementation descriptions can be obtained by referring to the description of the embodiment of fig. 1, and thus, no further description is given.
FIG. 3 is a schematic diagram of a connection port according to an embodiment of the invention. Referring to fig. 3, in order to make those skilled in the art further understand the detection method adopted by the connection port of the present invention, fig. 3 is a schematic diagram of an HDMI (High Definition Multimedia Interface) connection port chip that may be included in the connection port of the embodiments of the present invention, but the present invention is not limited thereto. The ports described in the embodiments of the present invention may also include other types of port chips (e.g., VGA port chips or DP port chips), and the following pin design can be modified to achieve the same testing function. In FIG. 3, connection port 430 includes a connection port die 431, and connection port die 431 includes a plurality of pins. These pins include, for example, DATA transfer pins D0-, D0+, D1-, D1+, D2-, D2+, clock pin CK-, CK +, mask pin D0Shield, D1Shield, D2Shield, CK Shield, control pin CE Remote, NC, display DATA channel clock pin DDC CLK, display DATA channel DATA pin DDC DATA, ground pin GND, power pin +5V, Hot plug (Hot plug) monitor pin DETHP, and idle pins SHL 20-SHL 25.
In the present embodiment, one of the pins of the connection port 430 may be used as a detection pin, and the detection pin may be coupled to a switch circuit (not shown). When the connection port 430 is coupled to an external display cable, the voltage level received by the switch circuit via the detection pin is changed from the first voltage level to the second voltage level, so that the switch circuit correspondingly enables the processor to perform a wake-up procedure or a power-on procedure. Specifically, the ground pin GND of the connection port 430 can be used as the detection pin. The ground pin GND may be coupled to the switch circuit through a node N1. The connection port 430 includes a resistor R1. One end of the resistor R1 is coupled to the ground pin GND and the node N1, and the other ends of the node N2 and the resistor R1 are coupled to the voltage source V1. In the embodiment, the power source V1 may provide a voltage signal of 3 volts (V), and the resistor R1 may be 20k ohms (ohm), but the invention is not limited thereto. In the present embodiment, when the connection port 430 is not coupled to an external display cable, the ground pin GND does not provide a current path, and thus the voltage source V1 does not provide current to the resistor R1, so that the voltage level at the node N1 will be the high voltage level (3V) as the voltage source V1. However, when the connection port 430 is coupled to an external display cable, the ground pin GND forms a current path with the external display cable.
That is, when the connection port 430 is coupled to an external display cable, the current provided by the voltage source V1 can be transmitted to the ground pin GND through the resistor R1, and after the current provided by the voltage source V1 flows through the resistor R1, a cross voltage is generated across the resistor R1. Therefore, the voltage level at the node N1 (the end of the resistor R1 coupled to the ground pin GND) will change from a high voltage level to a low voltage level. In other words, when the voltage level received by the switch circuit coupled to the node N1 via the detection pin changes from a high voltage level to a low voltage level, it indicates that the connection port 430 is already coupled to an external display cable. At this time, the switch circuit will correspondingly enable the processor to perform a wake-up procedure or a boot procedure.
However, the detection pin is not limited to the ground pin GND. In one embodiment, any of the free pins SHL 20-SHL 25 of the port 430 can also be used as the detection pin. Any one of the idle pins SHL 20-SHL 25 may be coupled to the detection circuit composed of the voltage source V1, the resistor R1, and the terminals N1 and N2, and the terminal N1 is coupled to the switch circuit. Even in another embodiment, the hot plug monitor pin HP DET of the connection port 430 may also be used as the detection pin, and the hot plug monitor pin HP DET may be directly used for detection. In detail, when the connection port 430 is coupled to an external display cable, the hot plug detect pin HP DET is at a high voltage level. When the connection port 430 is not coupled to an external display cable, the hot plug detect pin HP DET is at a low voltage level. That is, the switch circuit can directly detect the hot plug monitor pin HPDET. When the voltage level received by the hot plug monitor pin HP DET changes from a low voltage level to a high voltage level, it indicates that the connection port 430 is coupled to an external display cable, and therefore the switch circuit correspondingly enables the processor to perform a wake-up procedure or a power-on procedure.
FIG. 4 is a flow diagram of a boot method according to an embodiment of the invention. The booting method of the embodiment can be applied to the computer devices 100 and 200 of the embodiments in fig. 1 and 2. Refer to fig. 2 and 4. In step S510, the computer apparatus 200 operates the processor 210 in a sleep mode or a power-off mode. In step S520, the computer device 200 detects whether the connection port 230 is coupled to the monitor cable 330 by the detection pin of the connection port 230. In step S530, when the connection port 230 is coupled to the display cable 330, the computer device 200 outputs an enable signal to the switch circuit 220 through the connection port 230, so that the switch circuit 220 enables the processor 210. In step S540, the computer device 200 drives the external display 340 via the connection port 230 and the display cable 330. That is, the user can wake up or turn on the computer device 200 by coupling the display cable 330 coupled to the external display 340 to the connection port 230 of the computer device 200. Therefore, the booting method of the present invention can directly wake up or turn on the processor 210 of the computer apparatus 200 by coupling the display cable 330 to the connection port 230 of the computer apparatus 200 without turning on the display 240 of the computer apparatus 200, and can directly obtain the computer screen through the external display 340.
In addition, other technical features and implementations of the processor 210, the switch circuit 220 and the connection port 230 of the present embodiment can also be obtained by referring to the descriptions of the embodiments of fig. 1 to 3 to obtain sufficient teachings, suggestions and implementation descriptions, and thus are not described again.
In summary, the computer apparatus and the booting method of the invention can make the switch circuit wake up or boot the processor in real time according to whether the voltage level of the detection pin of the connection port changes. That is, the user does not need to press the power button and turn on the built-in display of the computer device to start the computer device, and the computer device and the starting method of the invention can directly judge whether an external display cable is coupled to the connection port of the computer device according to the detection pin position of the connection port, so as to quickly and conveniently start the computer device and display the computer picture through the external display.
Although the present invention has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention.
