当执行时pm-suspend，我得到了I/O error。
检查了其他类似的帖子后，没有找到解决该问题的解决方案。
PC上的操作系统：
该电脑有双操作系统：
win8.1mint mate 17.2（3.16.0-38-通用#52~14.04.1-Ubuntu x86_64 GNU/Linux）。
被secure boot禁用了，win8的快速启动也禁用了。
行为pm-suspend：
该命令首先尝试睡眠，然后系统 1 秒后再次唤醒。
有时重启后pm-suspend可以工作，但再次重启可能会导致它不再工作。
pm-suspend.log中的关键错误提示是：
Thu Sep 24 20:39:44 CST 2015: performing suspend
sh: echo: I/O error
Thu Sep 24 20:39:45 CST 2015: Awake.
我不知道如何检查哪个部分导致了这个问题I/O error。

我的问题是：
- 如何检查哪个部分导致
sh: echo: I/O error pm-suspendmake无法工作的可能原因是什么？
更新
这个问题还没有解决，有人知道 mint mate 18 会解决这个问题吗？
答案1
我刚刚mint mate 18在笔记本电脑上安装，问题已解决。
我认为 mint 需要时间来完全支持新硬件，因此在旧硬件上使用新版本通常可以解决此类问题。
