I am having this weird issue of 2 computers that go into a lock the computer state periodically. Today a person told me that their computer does it about 10 times a day. They will working and then they will go to the bathroom or be doing something else and when they come back the computer screen is black and they have to hit a key and it shows the computer is locked and they hit enter (because they don’t have a password) and it get them back in. This just started this week on 2 computers. Any ideas?
