Publication number: 20170300136Abstract: 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.Type: ApplicationFiled: July 5, 2016Publication date: October 19, 2017Inventor: Pei-Ming Chang
