    • 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.
    • 提供具有时间计算装置的主板。 主板包括中央处理单元,芯片组和微控制器。 芯片组连接到中央处理单元。 微控制器包括时间计数器和存储第一值的非易失性存储单元。 当由微控制器检测到的母板的操作状态从断电状态切换到电源接通状态时,时间计数器开始计数时间。 当由微控制器检测到的母板的操作状态从电源接通状态切换到断电状态时,时间计数器停止计数时间并将计数值定义为第二值。 微控制器通过添加第一值和第二值来更新第一值,并将更新的第一值存储到非易失性存储单元。

    • A frequency and voltage adjusting method is provided for adjusting a clock frequency or an operating voltage of a first component of a computer system. Firstly, a control function of a computer keyboard is enabled. Then, an initiating signal is generated by the computer keyboard. After the initiating signal is received, a control key of the computer keyboard is depressed to generate a frequency-increasing signal, a frequency-decreasing signal, a voltage-increasing signal or a voltage-decreasing signal. The clock frequency is increased according to the frequency-increasing signal. The clock frequency is decreased according to the frequency-decreasing signal. The operating voltage is increased according to the voltage-increasing signal. The operating voltage is decreased according to the voltage-decreasing signal.
    • 提供了一种用于调整计算机系统的第一部件的时钟频率或工作电压的频率和电压调节方法。 首先,启用计算机键盘的控制功能。 然后,由计算机键盘产生启动信号。 在接收到启动信号之后,按下计算机键盘的控制键以产生增频信号,降频信号,升压信号或降压信号。 时钟频率根据增频信号而增加。 时钟频率根据减频信号而减小。 工作电压根据增压信号而增加。 工作电压根据降压信号而减小。
