A:AnswerThe new 7577 all have a finger print reader built in to the power button in the US.
As for the RAM, mine shipped with a single 16gb stick of DDR4. However, I can't say that they all ship this way.
A:AnswerI don't own this laptop personally, but I have read and watched many reviews and all of them say you can expect a maximum of 4-5 hours of light use (i.e. web browsing, Netflix, etc.) on a full charge.
A:AnswerI use this laptop mainly for solidworks, and have been working with 30-60 part assembly's smoothly, no real memory issues or CPU throttling, there are some thing I have noticed it has issues with but these issue are also present in a dell latitude e7450 which makes me think it is a bad model. I have not used it with revvit or any other softwares but keep in mind the card is not a Quadro or FirePro so some programs may not support the GTX card.
A:AnswerI'll answer my own question. After going to another large PC retailer in the area, many newer Dell products had the same security seal (some still had the old style). The old seal had thick diagonal lines and text regarding to check contents before signing receipt if seal was broken or package was damaged. The newer seal has some thin diagonal lines in the center of the seal and no text. I'm going to say it's most likely a new tape seal Dell is using for third party retail products.
