Computing device and power supply method of connection module

摘要

The disclosure discloses a computing device including a connection module, a processing unit and a logic expansion unit, and a power supply method of a connection module. The connection module includes a detection unit and a power switch. The detection unit is configured to detect whether the connection module is connected with an external peripheral device, and to generate a detection signal. The power switch is configured to receive a power switching signal and to provide a rated voltage to the connection module according to the power switching signal. The processing unit and the logic expansion unit are coupled to each other. When the computing device is at a normal mode, the processing unit is configured to provide the power switching signal, acquires a connection status between the connection module and the external peripheral device, and to control the logic expansion unit to record the connection status.

1. A computing device, comprising:
a connection module, comprising:
a detection unit configured to detect whether the connection module is connected with an external peripheral device, so as to generate a detection signal; anda power switch configured to receive a power switching signal, so as to provide a rated voltage to the connection module according to the power switching signal; a processing unit and a logic expansion unit, wherein the processing unit and the logic expansion unit are coupled to each other, and when the computing device is at a normal mode, the processing unit provides the power switching signal, acquires a connection status between the connection module and the external peripheral device, and controls the logic expansion unit to record the connection status; and a switching unit coupled to the processing unit and the logic expansion unit and configured to switch the power switching signal provided by the processing unit and the logic expansion unit according to which mode, the normal mode or a power saving mode, the computing device is under; wherein when the computing device is converted from the normal mode to the power saving mode, the logic expansion unit provides the power switching signal according to the connection status, such that the power switch stop providing electric power to the connection module which is not connected with the external peripheral device, and wherein the logic expansion unit continuously receives the electric power when the computing device is in the power saving mode.
