The low power levels supported by each stage are ON, (Standby), Suspend (Suspend), and Off (Off). The ON stage means a general usage environment, and the standby stage means that the power supplied to some circuits of the monitor is cut off, so that the monitor can be woken up within 3 seconds. In addition, the suspend stage means that only the minimum power is consumed, and the off stage means that the monitor is powered off.

On the other hand, according to Gartner statistics of the US market research agency, the power consumption composition in the office was the highest at 39%, and a solution was needed.

Further, the monitor and the computer system can not be controlled or interlocked with each other, and there is an inconvenience that the power must be shut down simultaneously in order to save power.

In order to solve this problem, in accordance with Korean Patent Application No. 10-1330212, which is filed and registered by the present applicant, the computer system performs the power saving mode according to the power-off of the monitor, Discloses a power control apparatus and method for a monitor and a computer system that can be released. However, in the prior art, the user has to turn off the power switch of the monitor so that the monitor and the computer system perform the power saving mode, so that the user must turn off the power switch of the monitor.
