Lenovo 710 S 13 KB Camera not detected fixed

I have Lenovo 710S 13KB the camera is not working, I tried to uninstall and reinstall the camera driver but the problem still exist, I even reformat my laptop, update the BIOS but with no avail. I suspect that the cause might be hardware problem like loose connection since when I am pressing the area where the camera is located the camera light goes on and off, so I tried to open up the laptop removed the cables and inserted it again firmly luckily my problem was solved. I understand that this is not always the solution for laptop camera problem but still I m sharing this, who knows the solution to my problem is the same to yours.
