Hi hkumar0202,
Based on your concern, to open the camera of your laptop I suggest trying the following steps.
1. Try to open the camera by pressing the FN+ESC.
2. Open the youcam application to check if the camera is now working.
3. If you still cant open the camera I recommend to download the driver
here.
--> go to camera section.
4. Make sure that you download the driver that matches your operating system.
5. After downloading install the driver then restart your computer.
Hope it helps,
Thank you for using FixYa.
