Abstract: A computer system includes a bridge having a transmitting channel and a controller, wherein the transmitting channel is controlled by the controller; a first slot disposed therein a first pin connected to the controller; and a second slot disposed therein a second pin connected to the controller. The controller is enabled through the first pin and the second pin while a first device is plugged in the first slot and a second device is plugged in the second slot. A data is transmitted to the first and second devices through the transmitting channel. Alternatively, the data is directly transmitted to the first device if only the first slot is plugged with the first device.

Abstract: A motherboard with overclocking and overvolting functions is provided. The motherboard with an overvolting function includes a specified component, a voltage regulator and a micro-controller. The specified component receives an operating voltage. The voltage regulator generates the operating voltage according to a reference voltage. The micro-controller is electrically connected to an external input device for receiving a control signal issued by the external input device and adjusting the reference voltage according to the control signal.

Abstract: A computer system including a first memory unit, a second memory unit and a switch unit is provided. The first memory unit stores a first BIOS. The second memory unit stores a second BIOS. The switch unit has a first configuration and a second configuration. Upon the computer system being started, the switch unit receives an enable signal. When the switch unit is in the first configuration, the enable signal is provided to the first memory unit to start the first basic input/output system. When the switch unit is in the second configuration, the enable signal is provided to the second memory unit to start the second basic input/output system.

Abstract: A motherboard having a time calculating device is provided. The motherboard includes a central processing unit, a chipset and a micro controller. The chipset is connected to the central processing unit. The micro controller includes a time counter and a non-volatile storage unit storing therein a first value. The time counter starts to count time when the operating state of the motherboard detected by the micro controller is switched from a power-off state to a power-on state. The time counter stops counting time and defines the counting value as a second value when the operating state of the motherboard detected by the micro controller is switched from the power-on state to the power-off state. The micro controller updates the first value by adding the first value and the second value and stores the updated first value to the non-volatile storage unit.

Abstract: A method for recovering a BIOS unit, an updating module thereof and a computer system are provided. When the computer system is in a standby mode, and the updating module is coupled with the computer system and detects that a first start unit is enabled, data in the BIOS unit of the computer system are overwritten with program codes stored in the storage unit.

Abstract: A restriction mechanism for a card is provided. The card includes at least one electronic component mounted thereon. The restriction mechanism includes a substrate, a slot, a latch, and a restriction member. The slot allows the card to be inserted in the slot. The latch is pivotally connected to one side of the slot. The latch is rotatable between a first position in which the card is locked in the slot by the latch, and a second position in which the card is allowed to disengage from the slot. The restriction member is used to prevent the latch from being rotated to the second position.

Abstract: A connector is provided. The connector is for connecting an electronic card. The electronic card comprises a first card side and a second card side, a first notch formed on the first card side, and a second notch formed on the second card side. The connector comprises a body, a first fixer and a second fixer. The body comprises a first side, a second side and a slot. The first fixer is disposed on the first side, wherein the first fixer pivots between a first orientation and a second orientation, and the first fixer abuts the first notch when the first fixer is in the first orientation. The second fixer is disposed on the second side, wherein the second fixer abuts the second notch via elastic force.

Abstract: The invention provides a BIOS management device and a method for managing a BIOS setting value. The invention determines whether to shut down a computer and to restore the BIOS setting value to a default state by detecting whether a restoring event occurs. In addition, the computer is shut down and the BIOS setting value is restored to the default state when the restoring event occurs. Therefore, the fault caused by the improper setting of the BIOS is eliminated.

Abstract: A computer and a BIOS clear button thereof are provided. The BIOS clear button is adapted to be electrically connected with a motherboard of the computer. The BIOS clear button includes a body, a key, and a connecting part. The body has a recessed portion and a plurality of protrusion portions disposed beside the recessed portion, wherein the protrusion portions protrude from the recessed portion. The key is disposed on the recessed portion, and the connecting part is connected to the body and is electrically connected with the motherboard.

Abstract: A motherboard for computer is disclosed. The motherboard includes a printed circuit board (PCB), a first slot, a second slot, and a control unit. The first slot, the second slot, and the control unit are disposed on the PCB. The first slot is for receiving-a first double data rate (DDR) memory module. The second slot electrically connected to the first slot is used for selectively receiving a second DDR memory module or a daughter card having a plurality of terminal resistors. The control unit is electrically connected to the first slot and the second slot. When the first slot receives the first DDR memory module, and the second slot receives the daughter card, the control unit can transmit data to the first DDR memory module by using the daughter card.

Abstract: An electronic device for electrically connecting a first audio module to a speaker is described. The electronic device includes a case, a circuit board, a first audio connector, a second audio connector, and an internal music module. Both the first audio connector and the second audio connector are disposed on the circuit board. The speaker electrically connects to the first audio connector, and the second audio connector electrically connects to the first audio module and the first audio connector. The electronic device preferably includes an audio input interface. At least part of the audio input interface is fixed on the case and thereby users can conveniently connect the first audio module to the electronic device.

Abstract: An electronic device capable of replacing a first battery with a second battery in a power-on condition is provided. The first battery and the second battery respectively have a first conducting sheet and a second conducting sheet. The electronic device includes a circuit board and a battery tray. The battery tray used for placing the first battery has a battery conducting sheet for contacting the first conducting sheet and transmitting the power of the first battery to the circuit board. The battery replacing method includes the steps of placing the second battery into the battery tray such that the second conducting sheet contacts the battery conducting sheet before the first conducting sheet is departed from the battery conducting sheet, and departing the first battery from the battery tray and placing the second battery into the battery tray completely.
