WMI 和 计算机电源设置 - 上次退出待机状态的日期/时间

发布于 2024-07-09 12:01:42 字数 154 浏览 12 评论 0原文

我试图找出计算机上次退出待机/休眠状态的时间。 我知道我可以通过观看 Win32_PowerManagementEvent 来得到这个,但这在这种情况下不起作用,因为我需要一些可以轮询的东西 - 有什么想法吗? 它不一定是 WMI,我只是假设它就在这个地方。

谢谢!

I'm trying to find out the last time a computer came out of standby/hibernate. I know I could get this by watching Win32_PowerManagementEvent, but that doesn't work in this instance as I need something I can poll - any ideas? It doesn't have to be WMI, I'm just assuming that's the place it would be.

Thanks!

事实上,就像通常发生的那样,我一发布就明白了这一点。

因此,为了监视计算机何时退出待机状态,即 Win32_PowerManagementEvent 中的 EventType 7,我使用了 Powershell。

Register-WmiEvent -query "Select * From Win32_PowerManagementEvent where EventType=7" -messagedata "Power Management Resume" -sourceidentifier "Resume"

然后我进入并退出待机状态,并执行 Get-PSEvent,这显示了我创建的事件。 我本来可以使用 -action 来分配一个脚本块在该事件发生时运行,但我正在寻找要轮询的内容。

Actually, as it usually happens, I figured this out as soon as I posted it.

So, to watch for when a computer comes out of standby, which is EventType 7 in Win32_PowerManagementEvent I used Powershell.

Register-WmiEvent -query "Select * From Win32_PowerManagementEvent where EventType=7" -messagedata "Power Management Resume" -sourceidentifier "Resume"

Then I went into and came back out of standby, and did Get-PSEvent, which showed my event I created. I could have just used -action to assign a scriptblock to run when that event occurs, but I was looking for something to poll.

太棒了,感谢您提供这个解决方案! 我设法使用您的脚本作为模板来运行我的脚本。 我可以使用任务计划程序运行它。

Register-WMIEvent -query "Select * From Win32_PowerManagementEvent where EventType=4" `
 -sourceIdentifier "Action Before Sleep" `
 -action {
    write-host "Sleeping time!"
    nircmd.exe speak text "Remember Keyboard cover"
      }
      
#Get-EventSubscriber
#unregister-Event -subscriptionid 3

Awesome, thank you for this solution! I managed to get my script working using yours as a template. I can just run this using Task Scheduler.

Register-WMIEvent -query "Select * From Win32_PowerManagementEvent where EventType=4" `
 -sourceIdentifier "Action Before Sleep" `
 -action {
    write-host "Sleeping time!"
    nircmd.exe speak text "Remember Keyboard cover"
      }
      
#Get-EventSubscriber
#unregister-Event -subscriptionid 3
