My integrated camera on my lenovo notebook isn't working,it has veriface but no camera

Hi. I think the problem on that one is that the camera on your laptop is just disabled. To enable it you just need to press and hold the Function (Fn) button + Escape(Esc) on your keyboard to enable it then you can now use your veriface software. If not just try closing the veriface screen and try using your password instead. If not you need to uninstall your veriface software and download it from the lenovo driver support website and install it again on your machine and you need to enroll again your face for the security. By the way here is the website consumersupport.lenovo.com, you just need to enter the serial no of your machine and it will give you every software and drivers available for your machine. Hope this helps
