One way to wake up your computer at a scheduled time is to enter your computer’s BIOS and set a wakeup alarm in the Power Management settings. This will be managed either by APM or ACPI settings, depending on the age of your BIOS and any modifications made by the motherboard manufacture...

[ChatGPT]: "RTC wake system from S5" 是一种计算机 BIOS 设置选项,用于控制在关闭电源状态下(S5 状态)是否允许 RTC(Real-Time Clock)定时唤醒系统。 RTC 是计算机中用于实时计时的时钟,通常集成在主板上。RTC 在电脑关机或进入 S5 状态(完全关闭状态)时仍然保持运行。在某些情况下,例如需要在特定时间自动唤醒...

On many systems, the alarm interrupt can be configured as a system wakeup event, which can resume the system from a low power state such as Suspend-to-RAM (STR, called S3 in ACPI systems), Hibernation (called S4 in ACPI systems), or even "off" (called S5 in ACPI systems). On some...
