    • A mechanism for firmware to gain control from the operating system of an Advanced Configuration and Power Interface (ACPI)-compliant computing device during sleep-state transitions even if the computing device lacks a dedicated means for such a change to occur is discussed. Embodiments of the present invention report a CPU-only reset register in place of a sleep control register for an ACPI-compliant computing device in which an operating system is attempting a sleep-state transition. A CPU reset value is substituted for a sleep type value in a sleep-state object and written to the CPU-only reset register that was reported instead of the sleep control register thereby triggering a CPU-only reset. Firmware code operating at a known CPU reset vector may perform specified processing and then authorize a transition to the originally requested sleep-state.
    • 讨论了固件在休眠状态转换期间从高级配置和电源接口(ACPI)兼容的计算设备的操作系统获得控制的机制,即使计​​算设备缺少用于发生这种改变的专用装置。 本发明的实施例报告CPU仅重置寄存器,代替用于符合ACPI的计算设备的睡眠控制寄存器,其中操作系统正在尝试睡眠状态转换。 CPU复位值代替睡眠状态对象中的睡眠类型值,并将其写入仅报告的CPU专用复位寄存器,而不是休眠控制寄存器,从而触发仅CPU复位。 在已知的CPU复位向量操作的固件代码可以执行指定的处理,然后授权转换到最初请求的休眠状态。

    • When the user of a personal computer performs the ending operation of OS, a BIOS does not turn off power immediately but restarts the personal computer through software reset to execute POST and holds the state of the personal computer, immediate before starting the OS after completion of the POST, in a volatile memory before making a transition to power save mode. When the personal computer is started, the BIOS omits execution of the POST and performs only restor processing from power save mode thus starting the OS immediately. With such an arrangement, starting time of the personal computer can be shortened by omitting execution of the POST at the time of starting the personal computer. Processing required at the POST is performed following the ending operation of OS and the completed state of POST after restart is held in a volatile memory thus bringing about power save mode. Power is turned off if the main power supply is disconnected or a battery is dead; but since the OS has ended, the data is not lost unlike conventional technology where a transition is made to standby under a state using the OS.
    • 当个人计算机的用户执行OS的结束操作时,BIOS不立即关闭电源,而是通过软件重置来重新启动个人计算机以执行POST并且在启动操作系统之前立即保持个人计算机的状态。 POST,在转换到省电模式之前在易失性存储器中。 当个人计算机启动时,BIOS省略POST的执行,并且仅从节电模式执行恢复器处理,从而立即启动OS。 通过这样的布置,可以通过在启动个人计算机时省略POST的执行来缩短个人计算机的开始时间。 在POST结束操作之后执行POST所需的处理,并且在重新启动之后POST的完成状态被保存在易失性存储器中,从而实现节电模式。 如果主电源断开或电池电量不足,电源关闭; 但是由于OS已经结束,与在使用OS的状态下转换为待机的传统技术不同,数据不会丢失。
