Description

Electronic device and detection method

The present disclosure relates to an electronic device, and more particularly to a detection technology for a motherboard battery of an electronic device.

Generally, a motherboard battery is usually installed on a motherboard of a general computer. The motherboard battery is, for example, a lithium battery, for supplying power to, for example, a clock chip and a CMOS random access memory (RAM). In the traditional computer manufacturing process, the detection of the motherboard battery is measured by a manual operation three-meter meter, but there may be human error and the problem cannot be found in time, and it is impossible to detect whether there are other problems in the overall power supply path.

In addition, the traditional detection can also determine whether the motherboard battery is normal according to the real-time clock (RTC) provided by the clock chip, because the clock chip will operate with the power supplied by the motherboard battery, so the motherboard battery When there is no power, the real-time clock will return to the factory defaults (for example, back to 2010/1/1). Therefore, based on the system time adjustment with the real-time clock of the motherboard, when the user finds that the time of the system returns to the factory default value, it can be known that the battery on the motherboard is not properly powered (no power or failure). .

However, in the Microsoft operating system window 8 or later, for example, the date/time of the system itself automatically corrects or re-records the real-time clock of the motherboard to synchronize the time. For example, when the system time is greater than the motherboard time, the system will modify the host. The real-time clock of the board, when the system time is less than the time of the motherboard, the system will re-record the real-time clock of the motherboard. Therefore, the traditional method can not effectively judge whether the motherboard battery has normal power supply.

A detection method is proposed in one of the technical aspects of the present disclosure. The detection method is used to detect the motherboard battery of the electronic device. The detecting method comprises the following steps: filling in the detected value in the idle address register of the random access memory of the electronic device, wherein the motherboard battery is used to supply the power of the random access memory; and detecting whether the idle address register is The detection value is maintained; when the idle address register maintains the detection value, it is determined that the motherboard battery is normal; and when the idle address register returns to the initial value, it is determined that the motherboard battery is faulty.

An electronic device is proposed in another aspect of the disclosure. The electronic device includes a motherboard, a random access memory, a motherboard battery, and a processing unit. The random access memory is disposed on the motherboard. The motherboard battery is disposed on the motherboard and electrically coupled to the random access memory to supply power of the random access memory. The processing unit is disposed on the motherboard and electrically coupled to the random access memory. The processing unit is configured to write the detected value to the idle address register in the random access memory, and is configured to detect the idle address. Whether the scratchpad maintains the detected value. When the idle address register maintains the detection value, the processing unit determines that the motherboard battery is normal, and when the idle address register returns to the initial value, the processing unit determines that the motherboard battery is faulty.

The disclosed document uses the power-dependent characteristics of the random access memory to determine whether the motherboard battery is normally powered, and does not need to be manually detected, thereby reducing the possibility of human error, and can also be applied to the operating system after Windows 8.

The following detailed description of the embodiments of the present invention is intended to be illustrative of the invention, and is not intended to limit the invention, and the description of structural operation is not intended to limit the order of execution, any The means for re-combining the components, resulting in equal functionality, are within the scope of the present disclosure.

The terms used in the entire specification and the scope of the patent application, unless otherwise specified, generally have the ordinary meaning of each term used in the field, the content disclosed herein, and the particular content. Certain terms used to describe the disclosure are discussed below or elsewhere in this specification to provide additional guidance to those skilled in the art in the description of the disclosure.

Please refer to FIG. 1 . FIG. 1 is a schematic diagram of an electronic device 100 according to an embodiment of the disclosure. The electronic device 100 is, for example, a desktop computer, and includes a motherboard 110, a random access memory 120, a motherboard battery 130, a processing unit 140, a display 150, and a speaker 160. The random access memory 120, the motherboard battery 130, and the processing unit 140 are all mounted on the motherboard 110. The processing unit 140 is, for example, a component having a computing processing function, such as a central processing unit (CPU) or a system single chip (SoC), and is electrically connected to the random access memory 120, the display 150, and the speaker 160, respectively, and can be accessed or The random access memory 120, the display 150, and the speaker 160 are controlled. In detail, the processing unit 140 can read the data in the random access memory 120 or write the data to the random access memory 120. The processing unit 140 can also control the display 150 to display images and control the speaker 160 to generate sound.

In one embodiment, the random access memory 120 is a complementary metal oxide semiconductor random access memory (CMOS RAM) in a computer with a basic input/output system (BIOS), CMOS RAM. It can be used to store the setting result of the basic input/output system of the electronic device 100 (for example, user login data, system environment setting, etc.). It should be noted that the random access memory 120 has an electrical property, that is, the random access memory 120 must be powered on to continuously save data, and once the power supply to the random access memory 120 is suspended, the random access memory All the data stored in the body 120 will automatically disappear. Therefore, the random access memory 120 must be electrically connected to the motherboard battery 130 to maintain the power supply of the random access memory 120 itself. Even if the electronic device 100 is turned off or turned off, the random access memory 120 can continue to save data as long as the power supply of the motherboard battery 130 is normal.

In this example, since the random access memory 120 is a CMOS RAM of a computer, which stores the setting result of the basic input/output system, if the random access memory 120 cannot be maintained due to power failure, the electronic device 100 Will not work properly. Therefore, the motherboard battery 130 must be tested to determine whether the function is normal and has power. In addition, when the power transmission path between the motherboard battery 130 and the random access memory 120 is faulty, the random access memory 120 is also Unable to receive stable power and the data disappeared.

Please refer to FIG. 2 , which illustrates a flow chart of a method 200 for detecting an embodiment of the disclosed document. The detection method 200 can be used to determine whether the motherboard battery 130 can be powered normally. The detection method 200 further determines the condition of the motherboard battery 130 based on the electrical characteristics of the random access memory 120. That is to say, when the motherboard battery 130 is normally powered, the random access memory 120 can hold the data. Conversely, when the motherboard battery 130 is not powered normally, the data of the random access memory 120 will disappear.

Specifically, the detection method 200 includes steps S210, S220, S230, S240, S242, S250, S252, and the like. In step S210, a detection value may be filled in an idle address register that is not occupied/used on the random access memory 120 during the manufacturing process of the random access memory 120 of the electronic device 100.

For example, please refer to the memory data area 300 of the random access memory 120 in one embodiment of the disclosure file shown in FIGS. 3A and 3B. The memory data area 300 of the random access memory 120 includes a plurality of address registers. The memory data area 300 is, for example, an array address register, wherein the memory data area 300 can be divided into 0 to N intervals, and the vertical direction can be divided into 0 to M intervals, that is, memory data. The area 300 has M x N memory addresses, where M and N are both positive integers. The intersection area of the 00th section and the 00th section of the vertical direction is the A ₀₀ address, and the intersection area of the 00th section and the 01st section of the vertical direction is the A ₀₁ address, which is located in the vertical section 10 and the horizontal direction. The intersection area of the 00 interval and the A ₁₀ address, and so on, is located in the vertical M section and the horizontal N interval and the intersection area is the A _MN address, as shown in FIG. 3A. That is, the memory data area 300 of the random access memory 120 includes a total of M×N address registers.

In the embodiment of FIG. 3A, it is assumed that there is an unoccupied idle address register C1 in the memory data area 300 of the random access memory 120, and the so-called unoccupied idle address register C1 is The unused address register C1 does not store meaningful data or valid values. In an embodiment, the unoccupied idle address register C1 stores a preset initial value. The idle address register C1 is located, for example, at the A ₂₂ address in the vertical 20th interval and the horizontal 02 interval, and the preset initial value is “00”. In step S210 of the detecting method 200, the idle address register C1 can be filled with a detected value "x", as shown in FIG. 3B, where x can be any value other than the initial value "00", for example. It is said that the detection value written to the idle address register C1 can be "33". Then, for example, when the electronic device 100 is assembled, the random access memory 120 is electrically connected to the motherboard battery 130, and the process proceeds to step S220. In step S220, the processing unit 140 will detect the data value of the idle address register C1.

If the processing unit 140 determines in step S230 that the idle address register C1 does not maintain the detection value "x" but returns the initial value "00" (ie, returns to the data of FIG. 3A), it indicates that the host The panel battery 130 is not able to supply power normally. The detecting method 200 proceeds to step S240 to determine that the motherboard battery 130 is in a fault state, and further transmits the text or image/video message through the display 150 of the electronic device 100 or through the electronic device 100 in step S242. The speaker 160 generates a beep to display a message that the motherboard battery 130 is faulty.

When the processing unit 140 determines in step S230 that the idle address register C1 still maintains the detection value "x", it means that the motherboard battery 130 can be powered normally, and the data of the idle address register C1 does not disappear. Then, the process proceeds to step S250 to determine that the motherboard battery 130 is normal, and further displays the text or image/image message through the display 150 of the electronic device 100 or generates a prompt sound through the speaker 160 of the electronic device 100 to display the motherboard battery in step S252. 130 is a normal message.

It should be understood that the prompt message indicating that the motherboard battery 130 is normal or faulty is not limited to being displayed only through the display 150 or the speaker 160. For example, any corresponding change mechanism triggered according to the detection result may be replaced by the disclosure file. practice.

With the electronic device 100 and the detecting method 200 disclosed above, the motherboard battery 130 no longer needs to be detected by manually operating the three-meter, and the system itself can display the status of the motherboard battery 130. Therefore, the false positives or operational negligence factors that may be generated by the human detection will be eliminated, and since the electronic device 100 can detect and display the results by itself, the labor cost is saved, and the detection process is more accurate and fast.

Although the embodiments of the present invention have been disclosed as above, it is not intended to limit the present invention, and any person skilled in the art can make some modifications and retouchings without departing from the spirit and scope of the present invention. The scope is defined as defined in the scope of the patent application.
