Abstract: A network status indication system utilizes indicators on a keyboard to indicate the network status of a computer. When a simultaneous activation of two predetermined keys is detected and when the number of simultaneous activations is odd, the network status is determined, thereby indicating the network status of the computer.

Abstract: A method for testing an electronic device is implemented with a host computer. The host computer detects a test status of the electronic device. The host computer stores a test order table that indicates the test status and test order corresponding to the test status. The host computer transmits a test order based on the test status and the test order table to the electronic device. The electronic device executes a self-test based on the test order.

Abstract: A computer and method executes an operation when a user places an object between a projector and a projection screen, wherein the computer is connected to the projector. The computer captures an image of the projection screen. Furthermore, the computer obtains coordinates of each pixel of an shape of a shadow of an object and calculates average coordinates of the shape of the shadow of the object, in response to a determination that the shape of the shadow of the object matches the predetermined shape. The computer executes an operation on the average coordinates of the shape of the shadow of the object.

Abstract: In a method controls a test process of an electronic device, a booting mode of a test program is set as a non-preemptible mode. The method invokes system service programs from a storage device of the electronic device upon the condition that an operating system (OS) of the electronic device is booted. The method further boots a user-defined service program, loads the test program to test a target object of the electronic device using the user-defined service program, then boots system application programs and user application programs of the electronic device.

Abstract: A testing method tests a network device using a testing system by determining whether the network device is turned on via a second port of the network device. When the network device is turned on, the testing system logs onto the network device via the second port. A network service application of the network device is implemented and an IP address of the network device is obtained. Accordingly, a network connection to the network device is established. The testing system implements additional service applications of the network device and tests features of additional applications via a first port of the network device.
