Trigger Task Scheduler in Windows 7 when computer wakes up from sleep/hibernate

Question

I don't want task scheduler or whatever to wake the computer, but when I open the laptop back up and the machine wakes I'd like that to be the trigger that task scheduler or something uses to run an app.

Solution 1

You can tick the “Run task as soon as possible after a scheduled start is missed” checkbox on the Settings tab for the task. That's for tasks at least that are scheduled regularly and fail to start due to sleep/hibernate/shutdown.

There doesn't seem to be a trigger "On waking from sleep", but you can probably use the “On Event” trigger. The interesting events seem to be from “Kernel-Power” and “Power-Troubleshooter”. System sleep generates an event from Kernel-Power with event ID 42. Wakeup is an event from Power-Troubleshooter with event ID 1.

Solution 2

The event-based solution suggested by Johannes worked well for me. I wanted a certain text file (my to do list) to open in Notepad every time I un-hibernated my computer (Windows 7). I set up a scheduled task to run with this event as a trigger:

• Log: System
• Source:Power-Troubleshooter
• Event ID: 1

This is working well for me.

Solution 3

Event 107 when resumed from sleep, and 42 from entering to sleep. I just try event 107 to trigger a program when resume from sleep, and it worked

Solution 4

There is a simpler method: Triggers > New > On workstation unlock > Any user. When putting the computer to sleep, you're actually (also) locking the machine, and on waking up you will see 'Locked' above the password field, assuming you're using a password.

Solution 5

Below is an AutoHotkey solution based on a similar question

Save the (one line) script below with file ending .ahk:

Send {Volume_Down 100} ; Turns the volume DOWN 100 intervals

To run it on login or when the computer wakes, there is a AutoHotkey script that attempts to solve this here, or you can run the script using Task Scheduler.

More information can be found here (control volume) and here (for using AutoHotkey).

"Kernel-Power with event ID 42" worked for me on Windows 7 when activating a bat-file on return from sleep mode

[anno]

For wake-up, Power-Troubleshooter did not work for me. The only event that gets fired is Kernel-General with ID 1.

[ThreaT]

This doesn't seem to work when the laptop power cable is unplugged though?

[Gene Pavlovsky]

To clarify, listen to event ID 42 in System log from source Kernel-Power as the sleeping event, and the event ID 1 in System log from source Power-Troubleshooter for computer's resuming (waking).

@ThreaT In Task Scheduler, in the Conditions tab, uncheck "Start the task only if the computer is on AC power"

[Dr.eel]

as @anno My System journal does not have any Power-Troubleshooter event ID 1. I tried to use "Kernel-Power event ID 1 - Time synced" but it raises long after wake, in my case task resumes OS at 7:00 but "Kernel-Power event ID 1" occurs only at 8:32 and 17:32. So it's not reliable. Is there any system registry switch to enable wake reporting to the log?

[elonderin]

a) this is not what the OP asked for b) it might not be desirable to run it on that event -- depends on the use case

@elonderin — The OP is asking how he can trigger the Task Scheduler when the computer is waking up from sleep/hibernate. I think I gave him a method how to do that.

[elonderin]

but your solution would also run when you just lock /unlock your account w/o any sleep state involved but the OP was asking for when coming out of sleep. Hence, depending on the use case this might be valid or not.

How I can trigger when the screen sleeps not the pc/system itself?

[jous]

The question was about doing anything when the computer resumes from sleep or hibernation. The question was not about how to turn the volume down.
