i have a Dell Inspiron 17 7000 Series 7746, and recently i change my battery because it was old(approx 5 years)and didn't stay charged more than 10 min,so i took my laptop to a local pc service and have it changed.The battery works fine now and has an autonomy around 3~4 hours,BUT if i keep my laptop plugged in,windows 10 will lock automatically in 10~20 min,pretty random,even if i use the laptop or not.When it's not plugged in,the problem doesn't appear. I have tried a lot of solutions like : -in the power options, Sleep - Hibernate after , are set both to "Never"(on battery/plugged in) -PCI Express - Link State Power Management (on battery :off/ plugged in : off) -System unattended sleep timeout is set more than 60 min

Try to take a look at "Control Panel\Hardware and Sound\Power Options\Edit Plan Settings" you should find the setting your looking for.
