我正在运行装有 Ubuntu 20.04 的 Toshiba Satellite L745。在我让机器进入睡眠状态或合上盖子几秒钟后，它会自动唤醒。我已禁用 BIOS 中列出的所有唤醒选项。
输出： cat /proc/acpi/wakeup | grep enabled
EHC1 S3 *启用 pci:0000:00:1d.0
EHC2 S3 *启用 pci:0000:00:1a.0
ECH1/ECH2 不会切换为禁用。这些行指的是每个 lspci 命令的两个 USB 主机控制器。不知道接下来该怎么做。
我也在论坛上看到有关机器无法进入深度睡眠的问题。
输出： cat /sys/power/mem_sleep
s2idle [deep] 似乎处于正确模式。
根据请求，查看下面与挂起相关的系统日志。不太熟悉挂起过程...最后一行是唯一一行显示已请求唤醒，但 CPU 在此行之前已恢复。任何帮助破译此内容的帮助都将不胜感激。

我最近重新安装了 Ubuntu，主要是为了尝试修复此问题（以及其他问题）。机器是全新安装的，没有更改默认设置。
如果您采取任何进一步的故障排除步骤，我们将不胜感激。
谢谢你，
乔
答案1
我遇到了类似的问题，我报告过正在进行的错误报告
对我来说，解决方案就在这个答案中：
我今天仍在使用那个旧答案，但是我使用的是答案中的第二个脚本：/lib/systemd/system-sleep/custom-xhci_hcd。
有时候我会关闭脚本，但会发生一些不寻常的事情，我不得不重新打开脚本。我无法完全解释为什么暂停/恢复会出现问题，所以当我发现某个方法有效时，我就会坚持使用它。
