Q. Upgraded to win 10 and now my laptop won’t lock or sleep when I close the lid. The computer stays on and kills my battery at night. I have gone into the control panel and adv settings in power to make sure that on lid close it is on sleep. Verified that yes it is. On win 8 my computer would lock when I close the lid but now it doesn’t do that either. Getting frustrated already with Win 10.

Answer.

its simple with the password lock when you close your lid:

go into settings

click on account

and click on SIGN IN WHEN

it should say when windows gets woken up what does it do

the drop down feature should allow you to lock it again
