Google or Duck Duck Go for a switch for your laptop to find a way to turn on the internal integrated cameras on laptops. For my Lenovo Yoga 510-15ISK, I reactivated my cam via FN + F8 or camera icon key.
I bought this Yoga laptop back in August 2016, last year, at a computer store in Saigon, Vietnam, back when I was 31 years old, as an Oregonian living in VN, & I used the cam with Windows & that was good.
But I was not able to use my cam on my Linux Ubuntu Mate operating system (OS) since I put that on back in like September 2016 and I was unable to turn on the webcam for the past year until today.
