Can someone please explain what happens when PowerChute triggers a system shutdown, is there a delay before the actual shutdown? I am interested in graciously stopping a running application in an unattended manner.

For example, if I manually select Shutdown in the Windows shell GUI, a running application receives a SessionEnding event notification and a custom handler can be implemented to stop threads, save data, etc. Is such a notification sent when PowerChute triggers shutdown?

Hi,

When installing PowerChute Personal Edition hibernation is enable on the Windows system. When the shutdown process is triggered PCPE will hibernate the system so any running app and files will be saved in their state and when the system restarts, they will return to the same state. When PCPE triggers the shutdown there is a 10 second delay before the system hibernates.

When PowerChute business Edition start the shutdown it runs shutdown /s /f /d UP:6:12 /c "PowerChute Business Edition has initiated a system shutdown." There will be a 30 second delay from the time logged on users are informed of the shutdown until the shutdown begins. PCBE also ships with a command file that will allow for hibernation. 

PowerChute Network Shutdown runs 

set /A delay=60 * %1
shutdown /s /f /t %delay% /d UP:6:12 /c "PowerChute Network Shutdown has initiated a system shutdown."

There is a 70 second delay from the time the OS shutdown command is given until it starts.

It does not include a hibernation command file.
