我有一台双启动 Win10/Ubuntu 18.04 笔记本电脑，但一直无法解决为什么只要不插电它就会关机的问题。
一开始我以为我忘了，电池没电了。但每次启动时，我都无法从 grub 菜单直接启动到 Ubuntu。我必须运行恢复和 dpkg，然后必须完全关闭电源才能回到 Ubuntu。
如果我不这样做，kubuntu 闪光屏幕后会出现黑屏闪烁，并且屏幕左上角的光标不会闪烁。
在 dpkg 之后关闭并重试并再次关闭，黑屏显示闪烁的光标，然后出现箭头光标，这让我知道 Ubuntu 这次将加载到登录屏幕。
发生这种情况时，电池充电量为 100% 或更少，但永远不会耗尽。我已将所有电源管理设置设为永不超时等，但无法找出原因。
插入电源后，我可以关闭笔记本电脑，也可以保持打开状态等，而且几天内都不会发生这种情况。我不知道如何阅读日志来查看是否是某事导致了这种情况。
更新：不确定这有什么关系，但昨天我注意到电池电量为 83%，持续了一个多小时。重新启动后，电池电量为 83%，并在短时间内充满电。今天，已插入电源超过 3 小时，盖子关闭；打开笔记本电脑，电池电量仍为 86%（关闭前）。现在 30 分钟后，电池电量仍为 86%，已插入电源。由于这在 Win 10 中不会发生，我不确定为什么它不显示充电进度。
