If you want to make sure Dashboard is loaded immediately when you log in, first open System Preferences in the Apple menu, then click the Accounts icon. Click the Login Items tab, and then click the + button below the list. Select Dashboard in your Applications folder, and click Add. Alternatively, you can use Dashboard KickStart.
You will not receive notifications if your Mac is off or in sleep mode.
