If someone had access briefly to your laptop at a coffee shop, could they cover the LED with black opaque cellophane?

This sort of attack is pretty specific, so you figure it’s only done by people who want something from you in particular. These sorts of physical prep steps are what I’d be looking at if someone were relying on the light. Hypothetically, I’d attack the light first then take advantage of the false assurance.

Missing or open cover is a little harder to miss.
