| 摘要 |
The present invention is to provide a method for simultaneously switching energy-saving modes of plural computer devices via a KVM switch including a CPU, a plurality of connection ports, a real-time clock (RTC) and a memory unit, wherein the memory unit stores a timetable containing at least one scheduled time and at least one corresponding energy-saving procedure each including a control instruction. The CPU reads the current time of the RTC and, after determining that the timetable contains a scheduled time corresponding to a current time, reads the control instruction in the energy-saving procedure corresponding to the scheduled time. Then, the CPU sends an energy-saving instruction to the computer device connected to each of the connection ports that are specified in the control instruction, thereby switching the energy-saving modes (e.g., a hibernation mode, sleep mode, OFF mode or ON mode) of the specified computer devices simultaneously.
