Abstract:
1. A process for a monitor to operate in a DPMS mode, which applies when a user switches the monitor from a first working mode to a second working mode and the monitor ends the first working mode and enters the DPMS mode, the process comprising the following steps: detecting whether there is a signal input to a connecting interface for the second working mode by a signal processor; when there is no signal input to the connecting interface, the signal processor informing a micro-controller to open a signal detecting function so that the micro-controller detects the signal input of the connecting interface; turning off the signal processor; detecting whether there is a potential change to a pin of the micro-controller; when the pin has no potential change during a predetermined time interval, the micro-controller entering a sleep mode and waiting for the pin having a potential change.
