I haven't installed any new software. I don't have the Samsung Magic SSD software mentioned in other posts, and the only devices configured to wake the laptop are the mouse and keyboard, neither of which is touched when the laptop wakes up. Any suggestions
on how this can be delayed until I wake up the laptop would make my wife very happy. I do have a scheduled task to wake the laptop to run the AV software while I'm away, but that's hours after it's actually waking up. Thanks!

Answer 1

try to go to Control Panel\All Control Panel Items\Administrative Tools
Disable and set the trigger as never at task scheduler > time sync
You can also try to clean boot
