我有一个Dell XPS(9550修订版-本质上与现成的Ubuntu可用的Precision 5510相同),令人惊讶的是,它几乎总是可以在16.04下正常工作。但是在最近几天,使用电池供电1 时,suspend已停止工作。
基本上,笔记本电脑似乎处于挂起状态,但是当我将其唤醒时,它将经历正常的启动过程。
这是/var/log/syslog
挂起日志记录中的最后几行:

有什么东西跳出来吗?接下来的几行似乎正是您从冷启动中所期望的:

最近,除了内核版本4.4.0-59
(以前是4.4.0-57
)外,没有太大变化,并且我调整了BIOS选项以禁用我的嵌入式声音设备(因为恢复后没有更改)。
最后,这是成功的挂起/唤醒的样子(使用电池供电时):

请注意,某些“唤醒后”消息(始于13:16:52
)实际上与导致挂起的动作有关。我猜想日志记录工具会在挂起期间的某个时间点关闭,以便该点之后的消息仅在唤醒后才会显示(因此在失败的情况下我看不到这些消息)。
1特别是,如果笔记本电脑在整个可疑过程中都处于交流电源状态-挂起时,唤醒时以及之间的所有时间,挂起均可以正常工作。在主机处于休眠状态时,只需拔下AC适配器,甚至一秒钟,都将导致上述故障。
