    摘要: In a system and method for testing a serial port of a computing device, the serial port electronically connects to a test fixture. Test data is sent to a receive data (RXD) pin by a transmit data (TXD) pin. A test result is received from the serial port by the RXD pin. The TXD pin and the RXD pin work normally if the test data is identical to the test result. When voltages of a request to send (RTS) pin and a data terminal ready (DTR) pin are set at high level, the RTS pin, a data carrier detect (DCD) pin, the DTR pin, a ring indicator (RI) pin, a data send ready (DSR) pin and a clear to send (CTS) pin work normally, upon the condition that status values of the serial port indicate the voltages of the above six pins are at high level.

    摘要: A method tests hard disk ports located on a motherboard of a computing device. Each of the hard disk ports connects to a respective serial port of a test fixture. The test fixture includes a group of serial ports, a multiplexer and a storage device. Each of the hard disk ports is selected to be tested during the process of hard disk ports test. A data transmission path is formed by building a connection between the storage device and a channel of the multiplexer corresponding to the hard disk port. Data are written to the storage device and read from the storage device through the data transmission path. The hard disk port is working normal if the written data are identical to the read data. The hard disk port is not working normally if the written data are not identical to the read data.

    摘要: A display apparatus includes a photoelectric sensor disposed on an inner side of a frame and located corresponding to a corner of a pixel area of a display panel in a predetermined position. When the display apparatus is turned on, the display panel provides a light spot at a corner of a current pixel area of the display apparatus corresponding to the photoelectric sensor, and a micro-control circuit compares an electronic signal received from the photoelectric sensor with a sample value. If different, an interrupt is triggered to execute a position offsetting interrupt program to adjust the display parameter of the display apparatus, thereby moving the pixel area to adjust the relative position of the light spot and the photoelectric sensor, so that the relative position becomes identical to that when the pixel area of the display panel is in the predetermined position.

    摘要: In a method for adjusting display parameters of a monitor of a computing device, the computing device electronically or wirelessly connects to a mouse that includes a primary button, a secondary button, a scroll wheel, a function button and a microcontroller. The microcontroller detects whether the function button is pressed, clicking of the primary button or the secondary button, motions of the scroll wheel, and motions of the mouse. An adjustment mode of the monitor is predefined. The monitor is controlled into the adjustment mode by pressing the function button. The display parameters can be adjusted with the primary button, the secondary button or the scroll wheel when the monitor is in the adjustment mode.

    摘要: In a screen protection system and method, a first operation temperature of an electronic device is detected from each of one or more first temperature sensors, and a first ambient temperature is detected from a second temperature sensor, when a display screen is activated. Once there is no operation on the electronic device, a timer is started timing. Once the electronic device is being operated, a duration is temporarily stored and the timer is reset. If the duration is equal to a screensaver time, a second operation temperature of the electronic device is detected from each of the first temperature sensors, and a second ambient temperature is detected from a second temperature sensor. The method further determines whether the electronic device is currently being held by a hand of a user, according to the above-mentioned temperatures. If the electronic device is not being held by a hand of the user, the display screen is controlled to be in an inactive state.
