ACPI规范标准6.3资料
作为标准中最广为认可的部分，电源管理经历了较多的改进。
早先，Advanced Power Management模型(APM)将电源管理几乎完全分配给BIOS控制，这大大的限制了操作系统在控制电能消耗方面的功能。
当前，ACPI的电源管理特性以前只适用从便携式电脑（例如膝上型电脑）到桌面型电脑、工作站和服务器。例如，系统可能会进入极低功率消耗状态。这些就是可利用在多数桌面型电脑上的“睡眠”和“休眠”设置。睡眠和休眠状态可以通过移动鼠标，按键盘按键，从另外一台电脑接收一条信息（如果连接到了一个局域网）或者重大系统错误来唤醒系统。(ACPI standard 6.3 data

As the most widely recognized part of the standard, power management has experienced many improvements.

Earlier, the advanced power management model (APM) allocated power management almost completely to BIOS control, which greatly limited the function of operating system in controlling power consumption.

Currently, ACPI's power management features used to apply only to laptops (such as laptops) to desktops, workstations, and servers. For example, the system may enter a very low power consumption state. These are the sleep and sleep settings available on most desktop computers. Sleep and hibernation can wake up the system by moving the mouse, pressing the keyboard key, receiving a message from another computer (if connected to a local area network) or major system errors.)
