My laptop has locked me out. I have it set up so it asks for the admin password before it boots, then a pin for Windows. It's saying the system password is wrong, although I know it isn't. This happened the other day and finally worked after hours of trying different things, none of which actually helped. It just randomly accepted the password. Any advice would be awesome. I'm beyond frustrated. I have a screenshot but I'm not sure how to share it. When I turn it on, I see the Dell logo and pressing F2 or F12 does nothing, it goes straight to a box saying "Dell Security Manager."
