看到pcmag报道XBox因为加入新的功能,允许用户在当地电网使用renewable energy(可再生能源)时更新系统和游戏(这同时节省了用户的电费,因为众所周知可再生能源的市价一般都比较便宜),被美国保守派围攻了(众所周知保守派和climate change denier重合度非常高)的新闻,突然对XBox宣称的可以在Energy Saver Mode下更新提到的Energy Saver Mode感到好奇,于是查了一下。
XBox官方提到的Energy Saver Mode的典型功耗是0.5W(有些型号是0.4W)。

🤔有这么省电?
@Orca 低功耗模式本來也不怎麼耗電,定時喚醒聯網檢查一下有什麼該做的就好了。
@Orca 我不清楚你是否是 Xbox 用家,Xbox 中選擇關閉主機之後就會進入這麼一個深睡眠的模式。實際上和關閉了差不多,但是可以用控制器喚醒,也可以快速恢復系統。

我非XBox使用者。我觉得这可能是一个类似S3睡眠的模式。普通的家用电脑很多硬件上并不支持这种睡眠模式(常见于笔记本电脑),但既然微软对XBox的硬件设计有独断裁量权,那自然对于这方面可以有很大的决定权。

@Orca 那是當然的。同理還可以參考 Intel Mac。

But what about power, you ask? Am I running up my power bill? As long as your system BIOS supports the S3 ACPI (Advanced Configuration and Power Interface) mode, no. The S1 mode leaves the CPU and RAM powered up, the S3 mode powers those down. Our article from a couple years ago on how to check and change your BIOS sleep state is still relevant. My high-end system uses some 120-130 watts just sitting at the desktop (not including monitor), and uses 1 watt when powered off (most computers draw a very small amount of power, even when off, so they can do things like turn on when you press the power button). In sleep mode, my system draws a whopping 5 watts. Five. What does that different of 4 watts mean to you?
能在待机的情况下以0.5w的功率运行的机器还是不太常见的。
