A CPU core unlocking device applied to a computer system is provided. The core unlocking device includes a CPU having a plurality of signal terminals and a core unlocking executing unit having a plurality of GPIO ports connected with the corresponding signal terminals of the CPU. The GPIO ports of the core unlocking executing unit generate and transmit and transmit a combination of core unlocking signal to the signal terminals of the CPU to unlock the CPU core.

CPU core unlocking device applied to computer system

A motherboard capable of detecting consumed power and a method for detecting consumed power thereof are provided. The motherboard includes a VCC layer, a plurality of resistance elements, and a detecting module. A plurality of power traces are laid at the VCC layer, and each of the power traces conducts an operating voltage, respectively. The resistance elements are laid at sources of each of the power traces, respectively. The detecting module is coupled with each of the resistance elements, respectively, to obtain a current value of a current flowing through each of the resistance elements, and generates consumed power corresponding to each of the operating voltages according to the current value and the operating voltage corresponding to the current value.

Motherboard capable of detecting consumed power and detection method thereof

A motherboard which can play an image or a video in a power-off state is disclosed. The motherboard includes a circuit board, a north bridge chipset, a digital photo frame chipset, and a switch unit. The north bridge chipset, the digital photo frame chipset, and the switch unit are disposed on the circuit board. The digital photo frame chipset is activated according to a stand-by power in the power-off state. The switch unit is electrically connected with the north bridge chipset and the digital photo frame chipset, respectively. The switch unit electrically communicates with the north bridge chipset or the digital photo frame chipset according to a triggering signal. The motherboard may utilize the stand-by power in the power-off state to display an image by a display device via the digital photo frame chipset and the north bridge chipset when a computer system is powered off.

A computer system includes a triggering device; and a motherboard, connected to the triggering device, further comprising: a memory stored with a setting parameter of a basic-input-output-system; and a counter connected between the triggering device and the memory; wherein an erasing signal, for erasing the memory, is outputted to the memory from the counter according to a triggering signal outputted from the triggering device while a boosting procedure cannot be successfully executed by the computer system.

Bios parameter erasing method and apparatus applied to computer system

A computer has a first BIOS unit, a second BIOS unit, a bus, a detecting unit, and a first delay unit. The detecting unit is connected to the bus, the first BIOS unit, and the second BIOS unit operationally. In addition, the first delay unit is electrically connected to the detecting unit for controlling the detecting unit to check a status of a bus signal on the bus after a predetermined delay time. Accordingly, the detecting unit may enable the first BIOS unit or the second BIOS unit to boot the computer system according to the state of the bus signal.
