My laptop is a NP750XDA from Hong Kong , it's the version with the i7.

Sometime ago i turned the samsung security camera and microphone blocker feature on, and left it like that , and recently i was trying to turn the camera and microphone back on and nothing happens with the short cut key and if i try to open samsung security only this ( the image attached below) shows up, and the camera app also just says camera not attached or found.

How would i activate the camera and mic back on without a like a full reset.

Please help
