Windows 10 has a new feature that can disable your computer when you’re not connected to the internet. This is great for people who don’t want their computer to be constantly online, but it can also be a security risk. The feature is called “Connected Standby.” When you turn it on, your computer will go into a low-power state and will only start up again if you connect to the internet. If you don’t connect to the internet, your computer will stay in Connected Standby mode and use less energy. There are some downsides to this feature. For one, if your computer is stolen or lost, someone could access it by connecting to it through Connected Standby mode. And if your internet connection goes out, your computer will stay in Connected Standby mode and use more energy than usual. Overall, Connected Standby is a useful feature that can save you money on your electricity bill and make your computer more energy-efficient. But be sure to keep an eye on your battery life and make sure you always have an internet connection available in case of emergency. ..
Note that this will only work for computers that are configured to login to a domain, not for Home editions.
