求助，笔记本睡眠后唤醒显示器不亮

我的 ideapad Y500 笔记本，合上盖子后会休眠，再次唤醒后机器正常工作，唯独显示器始终是黑屏，请问有人知道是什么状况么？
多谢～

贴一次挂起恢复的 /var/log/messages。记住挂起时间和恢复后黑屏然后按关机键的时间，自己截取日志。我们要看那段日志。

多谢回复。
我并没有找到挂起恢复的 message 日志。为此我特别先删除了 message 文件，睡眠系统，然后恢复。由于屏幕不亮，我用另一台机器 ssh 到我的电脑，发现并没有 message 文件被创建。是不是就可以说明挂起到恢复没有 message 信息输出?

那是不可能的。

你好，
我又重新试了一下，截取了下面的日志。

嗯。你这日志是 suspend 阶段，就是挂起阶段。恢复阶段你再找找。。。在它下面呢。

我又重新提取了下 log，后面有大量重复的内容，我就放到了文件里，麻烦您下载下。多谢了～
