A battery test unit 9 is connected to the control unit 5. When the battery test unit 9 is activated, the light display mode switching module 8 switches to display the battery power mode, and the battery level is detected by the control unit 5. The battery power digital signal generated by the measuring device 61 drives the light and dark states of the respective system lights dl, d2, d3, and d4 in the 1259599 system light group 7. In order to achieve the above functions, the present invention can be realized by the following embodiments. The fourth figure shows a simplified circuit function block diagram of the first embodiment of the notebook computer equipped with the battery power detecting device of the present invention. The notebook computer 100 includes a central processing unit i, a main memory 2, a display device 3, a basic input/output system memory 4 (bi〇s R0m), a system bus bar 10, and a bus bar bridge 11. (BUs BRIDGE), a busbar 12. 5H basic output into the memory* The basic input and output system program (BI〇s program) and system self-test program (Power) required for the startup of the computer device On Self Test (referred to as POST program). The display device 3 is connected to the bus bar bridge 110 via a display interface 30. An embedded controller 50 (Embedded Controller) is connected to the bus bar 12. The embedded controller 50 mainly includes a keyboard controller 51, and is connected to a keyboard device 52. The embedded controller 50 further includes a system management controller 53 (SMC) connected to a system management bus 54 ( SM Bus). The system management bus 54 is a two-wire multi-master bus bus bar architecture that allows a plurality of devices that can control the bus bar to connect to the bus bar. The system management bus 54 provides a control bus for the system and power management related work. The master device starts the bus transfer and provides the clock signal, and the slave device can receive the slave bus via the bus. The data sent by the primary device can also be transmitted to the primary device via the sink 1259599. The system management bus 54 is connected to a battery 6 (for example, a smart battery commonly used at present. In the standard connection line of the system management bus 54, the battery is connected by a clock line SCL and a data line SDa. The system management controller 53 can generate a system management signal SMI (System Management Interrupt) to the central processing unit 1 of the notebook computer. When the system management function is executed, when the embedded controller 50 sets a value After being stored in an internal register, the system management signal SMI is then generated to the central processing unit i. The second processing unit 1 can then manage the system management code according to the system stored in its main memory. The system management signal SMI is returned to process the execution of the value represented by the value stored in the register of the embedded controller 50. The internal controller 50 includes a main interface (H〇st Interface) connected to the busbar 12 as an interface for data transmission with the central processing unit. In a system architecture between a typical embedded controller and a computer device, the main interface of the embedded controller 50 includes two address regions, one of which is a hexadecimal 60H/64H address, which is connected thereto. The keyboard control is 51 for the input function of the standard keyboard, and the other address area is ten/, carry 62H/66H, which is connected to the system management controller 53 to perform system management functions. The system management controller 53 in the inner drum controller 50 is connected to the system light group 7, and the system light number group 7 includes a plurality of system light numbers dl, 11 1259599 d2, d3, and d4. The embedded controller 50 can control the lighting or blinking state of the system lights dl, d2, d3, d4 to display the system state of the notebook computer 100. When the notebook computer 100 is in a normal operating state, the respective system lights dl, d2, d3, d4 can display the system state of the notebook computer 100. When the user presses the operation test switch sw, a battery test signal si is generated by the test switch sw to the embedded controller 50. Therefore, the battery test signal si is used as the battery test unit 9 in the present invention. The function of the signal display mode switching module 8 is achieved by the embedded controller 50. When the system management controller 53 in the embedded controller 50 detects the battery test signal, the system signal group 7 is switched from the original system state display mode to the battery power display mode. In the battery power display mode, the system management controller 53 in the embedded controller 50 drives the system lights dl, d2, d3, d4 in the system light group 7, and the user can use the system. The lamp dl, d2, d3, d4 is turned off or blinking to indicate the amount of power in the battery 6. In a preferred embodiment of the present invention, the test switch sw is disposed adjacent to the system lights dl, d2 'd3, and d4 to facilitate the user to press the operation, and preferably in the notebook computer. Even if the LCD screen is off, the user can press and operate the test switch sw. Furthermore, the system lights dl, d2, d3, and d4 in the system lamp group 7 are disposed at the front edge of the casing of the notebook computer 100, or even when the liquid crystal screen of the notebook computer is turned off. The other 12 1259599 that looks at its status is suitable for the location. The generation of the battery test signal may also be generated by a preset button (e.g., a function key) of the keyboard device 52 to which the embedded controller 50 is connected. Fig. 5 is a block diagram showing a simplified circuit function of the second embodiment of the notebook computer equipped with the battery power detecting device of the present invention. This embodiment is substantially the same as the first embodiment described above, and includes a central processing unit 1, a main memory 2, a display device 3, a basic input/output system memory 4, an embedded controller 50, and a system bus 10 , bus bar bridge 11, a bus 12 and other components, the difference is that when the embedded controller 50 detects that a preset button or button group of the keyboard device 52 is pressed to generate a battery test signal s2 to When the controller 50 is embedded, the embedded controller 50 drives the state of the system lights dl, d2, d3, and d4 in the system lamp group 7 to indicate the amount of power of the battery. The sixth figure shows a flow chart of the method for detecting the battery level of the notebook computer in accordance with the invention and the system lamp number. First, the battery power detecting device detects the existing battery power (step 101), and converts the detected battery current into a battery power digital signal (step 102). The battery power digital signal is then received by the embedded controller via the system management bus (step 103). Then, the embedded controller detects the state of the battery test unit (step 104) to determine whether the battery test unit is activated by the press operation. (Step 105). If the battery test unit is not activated, the light source display mode switching module maintains the system state display mode (step 106). In this 13 1259599 mode, the system lights dl, d2, d3, d4 in the system light group can display, for example, the power indicator of the computer system, the hard disk access data, and the state of the charging system. On the other hand, if the battery test unit is activated, the light source display mode switching module switches to display the battery power mode (step 107). In this mode, the embedded controller drives the system lamp numbers dl, d2, d3, and d4 of the system lamp group, and displays the note by the lighting or blinking status of each system lamp number dl, d2, d3, d4. The amount of power stored in the computer battery (step 108). Since the battery power display function in the present invention is shared with the system lamp number, whether the notebook computer is mounted on the Docking, whether it is turned on, or whether the LCD is turned on or off, The battery level is easily known by pressing the simple test switch. The system lamp numbers dl, d2, d3, and d4 in the system lamp group 7 can be generally used as the indicator number by a single-color or two-color light-emitting diode, and can be replaced by other light-receiving lights or illumination patterns. As can be seen from the above embodiments, the present invention has a high industrial utilization value.
