我似乎遇到了一些挂起模式问题。每次我尝试挂起笔记本电脑时，它都会锁定屏幕。或者它可能会成功挂起，但片刻之后就会恢复。什么可能导致这种情况？
我在 HP dv5-1178er Pavilion 笔记本电脑（Intel Core 2 Duo）上运行带有 3.2.0-25 内核的 32 位 Ubuntu 12.04。
以下是相关日志部分：

答案1
在 HP Envy dv6 上，使用 acpitool(1)，以下操作可在 13.10 上运行（从 13.04 升级后；13.04 没有挂起问题）。
- 用于
acpitool -w列出可唤醒的设备。
设备 S 状态 状态 Sysfs 节点
--------------------------------------- 1. P0P1 S4 *disabled 2. KBD0 S3 *enabled pnp:00:07 3. PS2M S3 *disabled pnp:00:08 4. EHC1 S3 *enabled pci:0000:00:1d.0 5. EHC2 S3 *enabled pci:0000:00:1a.0 6. XHC S3 *enabled pci:0000:00:14.0ETC
USB 设备是 4、5、6。我怎么知道的？我将 sysfs 节点值与lspci|grep USB
- 用于
acpitool -W禁用 USB 设备：
acpitool -W 4；acpitool -W 5；acpitool -W 6
答案2
这类似问题在 ASUS Eeepc 1201n 上存在挂起后立即唤醒的情况：
那里发布的解决方案建议在/etc/rc.local文件中添加两个命令：
我发现的解决方案非常简单有效。导致笔记本电脑唤醒的唯一问题是需要禁用两个 USB 组件。为此，请编辑文件
/etc/rc.local：
sudo gedit /etc/rc.local
它看起来应该是这样的：
#!/bin/sh-e
# Rc.local
# This script is Executed at the End of Each multiuser runlevel.
# Make sure the script That will "exit 0" on success or Any Other
# Value on error.
#
# In order to enable or disable this script just change the execution
# Bits.
#
# By default this script does nothing.
# Added by Carlos TD
echo US15 | sudo tee /proc/acpi/wakeup
echo USB0 | sudo tee /proc/acpi/wakeup
exit 0
我所做的就是添加这两个命令：
echo US15 | sudo tee /proc/acpi/wakeup
echo USB0 | sudo tee /proc/acpi/wakeup
这些命令针对的是不允许笔记本电脑保持挂起状态的 USB 组件。从本地文件禁用它不会影响系统
如果您想要查看已启用以唤醒笔记本电脑的所有 USB 组件，则可以使用以下命令。您会注意到这两个组件不再启用（当然是在重启后）：
cat /proc/acpi/wakeup
这个非常好且简单的解决方案是我在这个论坛上找到的，然后将其应用于我的 eeepc。我认为对于许多有此问题的笔记本电脑来说都是如此。您只需通过测试哪些 USB 设备是问题所在，将这个技巧应用于每台机器即可。您可以通过对每个设备运行上述命令并测试睡眠功能来进行测试。我在这个论坛上找到了它：http://ubuntuforums.org/showthread.php?t=1969615
答案3
在我的华硕 1201N 上，仅添加
echo US15 | sudo tee /proc/acpi/wakeup
修复/etc/rc.local了暂停问题。
