Abstract: An electronic device supporting power consumption reduction can be operated in a power saving mode or in an active mode, and the electronic device includes a first processor and a second processor. The first processor is configured to be powered off when the electronic device is in the power saving mode. The second processor is configured to, when the electronic device is in the power saving mode, control peripheral hardware associated with a local bus of the first processor. The peripheral hardware includes at least one of the following: a display unit, an input unit, a BLUETOOTH unit, and a sensing unit.

Abstract: The present invention discloses a method for a data card to report a port, including: initializing a power-on startup module and a compact disk (CD) reporting and processing module in the boot phase, where the CD reporting and processing module is configured to report a data card as a CD, interact with a terminal, and realize CD reading; and reporting a data card as a CD to a terminal in the boot phase. The data card is reported as a CD after initialization of the power-on startup module and the CD reporting and processing module, rather than after the initialization of the power-on startup module in the boot phase and the user application modules in the network access phase. In this way, the terminal user can quickly find that the data card is reported as a CD after the data card is inserted, which improves the user experience.
