However, putting your computer to sleep will prevent updates, virus scans, scheduled backups, etc. from occurring. If you need to have certain things happen when you are away from the computer but don’t want a sleeping computer to prevent them from happening, you can actually schedule specific times for your Mac to go to sleep.
2. Click schedule at the bottom right of the window.
