Abstract
Official abstract text for this publication.
A power supply system of an electronic device and a power supply method thereof are provided. Directly detecting the power voltage, when a power anomaly of the power voltage is detected, the electronic device may enter the energy-saving mode immediately for reducing power consumption, and a required DC voltage may be provided directly from the battery.
First claim
Opening claim text (preview).
What is claimed is: 1. A power supply system of an electronic device, comprising: a voltage detecting unit, configured to detect a power voltage for generating a detecting signal; an AC/DC converting unit, configured to convert the power voltage to a DC voltage, and the DC voltage is provided to the electronic device; a control unit, coupled to the voltage detecting unit, when a power anomaly of the power voltage is detected by the voltage detecting unit, the electronic device…
