    • A computer system having an Advance Configuration and Power Interface-compliant, or ACPI, operating system performs certain machine specific tasks before going to a low power state. When the computer operating system indicates that entry into the low power state is desired, a microcontroller embedded in an input/output chip is alerted. Synchronization between the main processor of the computer system and the embedded microcontroller of the ACPI operating system is achieved, reducing the likelihood of system failure on the next boot operation. The embedded microcontroller then also causes the state of devices connected to the input/output chip to be saved. This helps the machine to go to a known state during the resume process.
    • 具有高级配置和电源接口兼容性的ACPI操作系统的计算机系统在进入低功率状态之前执行特定的机器特定任务。 当计算机操作系统指示需要进入低功率状态时,提醒嵌入在输入/输出芯片中的微控制器。 实现计算机系统的主处理器与ACPI操作系统的嵌入式微控制器之间的同步,降低了下次引导操作时系统故障的可能性。 嵌入式微控制器也将导致连接到输入/输出芯片的设备的状态得以保存。 这有助于机器在恢复过程中进入已知状态。
