我有一台运行 Ubuntu 16.10 的联想 X1 Yoga，几个月前，合上盖子时挂起/唤醒都没有问题。大约 3 个月前，它开始在合上盖子时进入睡眠状态，但在打开盖子时却无法唤醒。唯一的解决办法是按住电源按钮重新启动机器。
我正在使用笔记本电脑撰写这篇文章，所以我无法确切地告诉你当我关闭盖子时发生了什么（又名“进入睡眠状态；没有闪烁的电源灯”或“进入睡眠状态；闪烁的电源灯”），但我注意到当我在一段时间前关闭盖子后回来时，我得到了：
1) 电源按钮 LED 灯不闪烁
2）打开盖子时，我看到绿色电源 LED 闪烁，但没有显示屏背光，没有键盘输入（尝试调整背光作为测试），也没有桌面/密码提示。
3) 短按电源 LED 不会改变任何内容。摆弄键盘和鼠标也不会改变任何内容。
我有点想知道电源按钮上没有闪烁的灯光是否意味着笔记本电脑进入休眠模式（而不是像配置的那样只是挂起），也许这可能是问题的一部分。
我也不知道如何调试这个问题，因为虽然在挂起阶段可能会有一些日志输出，我可以在断电后恢复，但我找不到任何有关唤醒过程中失败的日志输出。如果它甚至没有尝试唤醒……我想这是有道理的。
那么，还有其他人遇到过类似的问题吗？有任何故障排除技巧吗？有任何修复技巧吗？
谢谢

答案1
上周我拥有的 Toshiba Satellite Pro C660D 也出现了这个问题。我尝试了所有能想到的方法，也曾在某个时候在这里发过帖子，大家一致认为用户端真的无能为力；这很可能是 Canonical 端的故障。从 U12.04 开始，它就运行正常，但在我拥有它大约一个月后，它开始像您描述的那样出现问题，我多次重新安装操作系统，甚至到 16.04 也没有解决。
我知道这没什么用，但我只是想让你知道，如果有解决方案，那也只是少数。我相信这种情况只发生在少数品牌和型号上（例如戴尔 XPS 笔记本电脑的一些原始型号）。
