Abstract

The present invention provides an electronic system with power saving function. In a first embodiment, the electronic system comprises a processing unit and a storage device. The storage device has a transmission interface, and the storage device is coupled to the processing unit via the transmission interface, wherein when the electronic system enters into a hibernate mode, the processing unit will turn off power supply of the storage device completely via the transmission interface. In a second embodiment, the electronic system comprises a processing unit and a storage device. The storage device has a transmission interface and an independent signal pin, and the storage device is coupled to the processing unit via the transmission interface and the independent signal pin, wherein when the electronic system enters into a hibernate mode, the processing unit will turn off power supply of the storage device completely via the independent signal pin.

Claims
