Computer device and method for converting working mode of universal serial bus connector of the computer device
First Claim
1. A computer device comprising:
- a universal serial bus (USB) connector connected to an external USB device, wherein the USB connector provides a quick charging mode or a general charging mode;
a power controller connected to the USB connector;
a first switch connected to the USB connector, wherein the first switch switches between a south bridge chip and a reader;
a controller connected to the power controller, the first switch, the south bridge chip and the reader, wherein the controller is configured to transmit a control signal; and
a charging controller connected to the controller, configured to transmit a quick charging command or a general charging command;
wherein;
when the controller receives the quick charging command, the power controller cuts off power to the USB connector and the USB connector is operated at the quick charging mode by switching the first switch; and
when the controller receives the general charging command, the power controller cuts off the power to the USB connector and the USB connector is operated at the general charging mode by switching the first switch.

Abstract
A computer device and a method for converting a working mode of a universal serial bus (USB) connector of the computer device. The computer device comprises a USB connector, a power interruption unit, a first switch unit, a south bridge chip, a reading unit, a control unit, and a charging control unit. The USB connector is linked to an external USB device. When a fast charging instruction is received, the power interruption unit interrupts the power supply of the USB connector; the first switch unit performs switching, so that the USB connector works in a fast charging mode. When the control unit receives a common charging instruction, the power interruption unit interrupts the power supply of the USB connector; the first switch unit performs switching, so that the USB connector works in a common charging mode, and data transmission can be performed.

14. A method of switching operation modes of a universal serial bus (USB) connector, adapted to a computer device, wherein:
-
the computer device includes; a USB connector; a first switch connected to the USB connector; and a second switch connected to a memory; wherein; the USB connector is connected to an external USB device, the first switch switches between a south bridge chip and a read; and the second switch switches between the south bridge chip and a controller; and the method of switching operation modes includes; receiving a backup trigger signal of starting a BIOS updating mode; cutting off power to the USB connector to initialize a state setting value of the external USB device and reset the south bridge chip of the computer device; delaying a reading time of the reader reading internal information of the external USB device; waiting a delay time after switching the first switch connected to the south bridge chip to the reader and switching the second switch connected to the south bridge chip to the controller; determining whether a notification signal of the delay time is up is received; reading a BIOS image file stored in the external USB device by the reader and determining whether the BIOS image file is an updatable version for the computer device if the notification signal is received; and updating a BIOS stored in the memory. - View Dependent Claims (15, 16, 17, 18)

19. A method of switching operation modes of a USB connector, adapted to a computer device, wherein:
-
the computer device includes the USB connector; a first switch connected to the USB connector; and a second switch connected to a memory; wherein; the USB connector adapted to be connected to an external USB device; the first switch switches between a south bridge chip and a reader; and the second switch switches between the south bridge chip and a controller; the method comprising; receiving a default power off command when the computer device is in a power on state, wherein the default power off command switches the computer device automatically to a quick charging mode after the computer device enters a power off state; detecting a backup trigger signal used for starting a BIOS updating mode when the computer device is switched to the quick charging mode; determining whether the external USB device connected to the USB connector includes a BIOS image file; and updating a BIOS of the computer device according to the BIOS image file when the external USB device includes the BIOS image file. - View Dependent Claims (20, 21, 22)
