Win 10 Task failing to run

[Confused]

I have been using Task Scheduler to run a backup to a NAS box overnight via a FreeFileSync batch but this stopped working about a week ago. I think there had been some updates to Windows 1803 but I can't be sure which one caused this.

The Task used to wake the computer from sleep to run and has been working fine for months up to now.

Any ideas how i can fix this?

Thanks

I've managed to figure this out. I had forgotten that I created a new Power Plan. This meant that the Allow Wake Timers setting had defaulted to Important Wake Timers Only. I have now set this to Enabled and the Task is running fine.
