答案1
答對了！在這篇 Reddit 貼文的幫助下，我似乎已經成功排除並解決了類似的問題：有沒有其他人注意到他們的電腦在更新到 Windows 10 後不再自動進入睡眠狀態？
排除故障的步驟：
- 使用電源效率診斷報告
正如 Harrymc 已經提到的，您可以使用該powercfg -energy命令來獲取其電源使用診斷的報告。結果可能指示錯誤、警告或其他有用信息，並儲存在此處：C:\Windows\System32\energy-report.html
例如我的總結報告是：
Energy efficiency problems were found.
9 Errors
24 Warnings
43 Informational
See C:\WINDOWS\system32\energy-report.html for more details.
以及更詳細的：

- 使用 powercfg -requests
在命令提示字元中輸入powercfg -requests（可能需要提升權限）。應該告訴你程式設計保留了什麼你的電腦已甦醒。對於我的報告，我得到：

決議
覆蓋保持視窗喚醒的編程。使用命令
powercfg -REQUESTSOVERRIDE告訴 Windows 忽略任何讓它保持清醒的東西並進入睡眠狀態。
例如，根據我的報告，我必須重寫Kernel DriverandConnectifyd過程。
筆記！ 您不必一定要覆蓋它，因為給定的驅動程式可能會因為PC 正在使用而使PC 保持喚醒狀態，一個很好的例子是上面的Intel 音訊驅動程序，在停止音訊後，它不再處於活動狀態。
我的罪魁禍首是這個過程 - Connectifyd。
儘管如此，要覆蓋相應的命令，請鍵入以下命令：
powercfg -REQUESTSOVERRIDE DRIVER "The Name of Your Device" SYSTEM
powercfg -REQUESTSOVERRIDE PROCESS "The name of Process" SYSTEM
例如
powercfg -REQUESTSOVERRIDE PROCESS "\Device\HarddiskVolume4\Program Files (x86)\Connectify\Connectifyd.exe" SYSTEM

看起來這個問題可能是由於 USB Root Hub 被允許喚醒您的電腦造成的。您會嘗試取消選取該方塊以查看它是否有效嗎？步驟如下：
- 在開始欄中搜尋「裝置管理員」。
- 開啟裝置管理員後，在底部附近展開“通用序列匯流排控制器”
- 找到“USB Root HUB”。可能會有不只一個。在每個 USB 根集線器上執行步驟 4-6。
- 右鍵點選 USB Root Hub > 屬性 > 電源管理。
- 取消選取“允許此裝置喚醒電腦”
- 好的 - 測試解決方案。如果該解決方案不起作用，請在重新檢查複選框之前嘗試重新啟動。
讓我們知道這是否有效！

對你的報告的檢查powercfg -energy沒有發現任何異常情況。據報告，您的系統具有休眠功能 (S4)，並且沒有明顯有問題的裝置（儘管最好在您不使用電腦或不播放音樂時進行休眠）。
以下是一些可能有幫助的建議。
在裝置管理員中防止裝置喚醒您的計算機，尤其是網路介面卡。您可以透過運行列出所有這些設備
powercfg -devicequery wake_armed。透過以下方式檢查 Windows 是否損壞證監會/scannow。如果發現問題並予以糾正，請勿認為問題已完全解決。
