Run scheduled task or a GPO when Win7 SleepMode is triggered?

Hello all, I'd like to launch a custom batch file when my computer goes into sleep mode. I would like to launch this batch through a GPO or task scheduler.

I've tested using task scheduler and the power event ID for sleep mode but it seems the event triggers too late for the application to run and the computer just continues into sleep mode.
I could create a scheduled task to trigger a minute before the idle time-out for sleep mode but this doesn't help if I actively put the computer into sleep mode.

Does anyone know of a way to do this?

Does your task need to run before going to Sleep, or would it be ok to run it on Wakeup?

Okay through testing I've discovered that using the event id for sleep-mode won't work because it is triggered too late for task scheduler, in fact task scheduler will read the event id after waking up and then trigger.

I was able to get task scheduler to trigger before sleep-mode based on idle timeout but this doesn't help when a user actively enters sleep-mode.

Going to check around on technet and try some experimenting.

Hi idecz,

It sounds like you know what you are doing and why.
I'm following this to learn from you :)

I wondered if the task would start after the wake-up, and you answered that with
"will read the event id after waking up and then trigger".

Can I ask, why do you need the task to run before sleep?
I'm a programmer, so i can understand there is a need ... disconnect from resources, logoff network accounts, kill a kiosc session, ... etc.

I'm just wondering if there might not be a better/easier/safer way to do what you need to do than using task scheduler.
