东芝在Ubuntu 14.04暂停后自动恢复

我有一台东芝L845和i当我暂停ubuntu时它会在2秒后醒来。 这里有一些信息。

最后：

pastebinit /var/log/pm-suspend.log 链接

我也发现了这种行为：

在AC模式下，如果我禁用蓝牙，系统暂停ok（我尝试了几次）在电池模式下，它总能正常工作。

我真的不明白发生了什么。

PD：对不起我的英文

谢谢

更新!!!!!!!!!!!!!!!!!!!!!!! 好吧，似乎一切都是随机的。 然后我做的另一件事是：

我意识到acpitool可以改变设备以免从挂起中唤醒（根据我读到的内容）

执行此命令后：acpitool -W 5

使用lspic我发现设备3,4,5是：00：1d.0 USB控制器：英特尔公司7系列/ C210系列芯片组系列USB增强型主机控制器＃1（转04）00：1a.0 USB控制器：英特尔公司7系列/ C210系列芯片组系列USB增强型主机控制器＃2（转04）00：14.0 USB控制器：英特尔公司7系列/ C210系列芯片组系列USB xHCI主机控制器（转04）

我不喜欢这个解决方案，但它是我现在所拥有的。 我不知道如何使此设置永久化，因为我在重启后丢失了更改。 任何的想法？？？ 我害怕有任何副作用

再次感谢
