Computer device and method of power management of the same

摘要

A method of power management of a computer device includes a number of steps. When a decision element determines that the computer device must enter a power saving mode, the decision element generates a power saving mode signal. When an embedded controller detects the power saving mode signal, the embedded controller determines whether an NFC transceiving module is sending or receiving information. If the NFC transceiving module is sending or receiving information, the embedded controller postpones entering into the power saving mode by the computer device until the NFC transceiving module finishes sending or receiving information.

1. A method of power management of a computer device in which the computer device comprises an embedded controller, a near field communication (NFC) transceiving module, a display module and a decision unit therein, and the decision unit is an image processing unit, the method comprising:
(A) when the image processing unit determines that the computer device is required to enter a power saving mode right now, the image processing unit generates a power-saving-mode signal for enabling the computer device to enter the power saving mode, wherein the embedded controller respectively switches a backlight module power pin and a display panel power pin of the image processing unit into a disable status from the enable status, (B) when the embedded controller detects the power-saving-mode signal, the embedded controller determines whether the NFC transceiving module is performing information communication; (C) when the embedded controller determines that the NFC transceiving module is performing information communication, the embedded controller requests a core logic set of the computer device to switch the backlight module power pin and the display panel power pin of the image processing unit back to an enable status from the disable status for postponing entrance into the power saving mode until the NFC transceiving module finishes performing the information communication; and (D) when the embedded controller determines that the NFC transceiving module is not performing information communication, the embedded controller shuts down electric power of the display module based on the power-saving-mode signal.
