Disable Sleep Mode in Windows 10
When Sleep Mode is enabled on a Windows computer, it automatically turns OFF its screen after a set period of inactivity and goes into a state of Low Power Mode, using very little power.
At any time, you can wake up the computer from sleep mode by pressing the Power button and it will immediately spring back to life, allowing you to start working on the computer.
With default Sleep Mode settings, most Windows computers go into Sleep Mode after 15 Minutes (While on battery) and 30 minutes (when pugged-in to a power supply) of inactivity.
While the default sleep mode setting is good enough for most users, it may not be suitable in certain cases or suitable for all users.

1. Disable Sleep Mode Using Settings
Go to Settings > System > select Power & Sleep in the left pane. In the right-pane, scroll down to “Sleep” section and set ‘When Plugged in’ setting to Never.
