Computer motherboard capable of reducing power consumption while suspended

摘要

A computer motherboard that reduces power consumption in a suspend-to-memory state. The computer motherboard has a newly added DS3W mode that has the ability to reduce the power consumption of the computer motherboard in suspend. With the new power saving control and power switch device added to the computer motherboard, the power of the main memory, the power saving control device, and the power switch device is continuously maintained, while the power of the other elements of the computer motherboard is turned off. Although all can be turned off, the computer motherboard still has the ability to wake up and recover from the traditional sleep S3 state, and can further reduce power. When the user presses the power button, the power saving control device and the power switch device restore the power supply to the previously powered off element. [Selection diagram] FIG.
