Abstract: A circuit board testing system includes a testing fixture. The testing fixture is used for testing plural wires of a cable of a circuit board. The testing fixture includes a first contact element, a switch circuit, a second contact element, a voltage acquisition element and a control unit. The first contact element is connected with input terminals of the plural wires. The second contact element is connected with output terminals of the plural wires. When the control unit drives a switching action of the switch circuit, a testing voltage is provided to the odd-numbered wires or the even-numbered wires. The control unit reads the voltage values of the odd-numbered wires and the voltage values of the even-numbered wires from the voltage acquisition element so as to judge whether the plural wires of the cable are normal.

Abstract: An input module includes an input device and a control program. The input device is in communication with a computer. The control program is installed in the computer. If a control signal from a processing unit of the input device has not been received by the computer for a predetermined time period after the control program is opened, the control program issues a command signal to the processing unit. After the command signal is received by the processing unit, the processing unit issues at least one response signal to the computer so as to prevent the computer from entering a hibernation mode.

Abstract: The present invention provides a power consumption testing system and a power consumption testing method for a wireless mouse. The power consumption testing system includes: a platform; a flexible thin sheet; a first movable fixed component; a second movable fixed component; a vibration motor; and a processing apparatus. The first movable fixed component is configured to connect the flexible thin sheet and the platform. The second movable fixed component is configured to connect the wireless mouse to the flexible thin sheet or the platform. The vibration motor is connected to the flexible thin sheet and is configured to shake the flexible thin sheet so that the wireless mouse continuously moves on the flexible thin sheet. The processing apparatus is wirelessly connected to the wireless mouse and is configured to read and record a voltage value of the wireless mouse to determine a battery capacity of the wireless mouse.

Abstract: A circuit board testing system includes a testing fixture and a computer system. The testing fixture includes a contact element, a switching circuit, a connection module, and a data acquisition unit. The contact element is connected with a circuit board. The switching circuit is connected with the contact element. The connection module is connected with the circuit board and the computer system. Consequently, an electric power is transmitted from the computer system to the circuit board through the connection module. By enabling the connection module, the data acquisition unit acquires a real voltage value corresponding to the electronic component. The computer system is connected with the testing fixture. According to the real resistance value, the computer system judges whether the electronic component passes the test.
