To get to the display you may have to find similar models on YouTube and look for screen replacement videos to see how to access the screen so that the camera module cable connection can be checked. I've searched online for a disassembly guide for the laptop but didn't find any for your model.

Check for locking bars, clips etc on connectors and if there are none pull out by the plug and not the wires. If something doesn't come undone or loose etc, don't get frustrated and apply force. There is still the danger of ESD damage caused by touching sensitive components with your fingers etc so using earthed wrist strap would be preferable, but if you're careful it should be OK. That way if anything goes wrong, tools slipping etc the risk of causing an electrical problem is negated. This doesn't mean that you have to remove it (although with some these days you do),just disconnect it. When working inside a laptop always disconnect the battery from the motherboard as soon as it is accessible and don't reconnect it until you've finished and have to close the laptop up. You're probably right about it being the display webcam, microphone cable and the cable near the power cable that was highlighted by you is most probably for something else if it doesn't go to a hinge.
