Unknown connector on laptop motherboard

I have an Acer Aspire E5-576G laptop. Upon opening the chasis i found that there are 2 unoccupied connectors, one i already know is for the led for versions with backlit keyboard, what's the other for?

None of them contain anything regarding the interior of the laptop. That was the first place i checked before posting here.

Definitely a ribbon cable that would connect to a device not included in your version of the laptop, perhaps a fingerprint scanner used for biometric scanning

Thanks for your response, but i have already figured that out the instance i saw the connector for the first time. The question is what is supposed to be connected to it, i am hoping someone with a version of that laptop, with that whatever device built in, can tell me.
