我有一台 HP EliteBook-8540p,它运行 Core™ i7 CPU Q 720 处理器和 12GB RAM。
自从我在 2016 年 3 月购买以来,它一直在运行 Ubuntu。
随着新版本的推出,我不断升级版本,它从未出过任何问题,直到 Focal Fossa,20.04。
暂停 Ubuntu 后,按电源按钮恢复,笔记本电脑恢复运行,但没有屏幕显示,并且似乎没有磁盘活动。
这是来自系统日志的内容,我曾尝试恢复,但最终不得不重启电源。
没有任何记录显示我尝试恢复。

我找到了一个安装了 16.04 的硬盘,我克隆并安装了它。
它运行正常,并从挂起状态恢复。
我运行了软件更新程序,然后 16.04 出现了同样的问题,它无法从挂起状态恢复,并出现了与 20.04 安装相同的故障。
我现在正在运行另一个 16.04 克隆,并禁用了更新。

从运行 16.04 安装开始。
