Establish a Clean Boot by unchecking everything in msconfig>Startup except AV: Startup Programs - Change. After reboot enter msconfig>Services, check the box to Hide All MS Services, repeat above. Check back periodically that nothing has written itself in to either list, turn it off in its Program Preferences or Uninstall it.

It's likely you have scheduled backup which cannot run due to external being unplugged, causing the Action Center notification.

Enter Backup Center (type backup into Start search) to adjust the schedule to when it is more convenient for you to have backup plugged in. You may not want to schedule backup, but just run it occasionally. If you schedule it, it's best to keep external plugged in.

You can also open the Action Center and tell it not to notify you about this or any other items posted.
