Welcome to the Community Forums.
Can you try to check the Screen Saver settings.
Right click on the screen and choose personalize, CLick on Lock Screen and Screen Saver setting should be at the bottom of the options.
Else you can try the steps described here.
Update us how it goes.

Similar probelm of SLEEP I'm facing when connecting the external USB Keyboard to my Lenovo Ideapad 320 laptop.
System goes to sleep after 2-3 minutes of connecting keyboard and when I again login to Windows it shows some numbers ( like thius - 12341234123412341234....... ) written in address bar /word/ notepad / sticky notes / ppt or where ever the cursor was left last before the sleep and I was typing.
Please resolve this at the earliest and let me know the solution.
