A:AnswerYes it does, but in order for it to work, you need to buy a hard drive and a sata connector to your motherboard, you can see an example of this in the picture attached, I highlighted what to pay attention to in red ink.
A:AnswerIt has a Dual Core, following is a more specific description:
7th Gen Intel® Core™ i7-7500U mobile processor
Ultra-low-voltage platform. Dual-core, four-way processing provides maximum high-efficiency power to go.
The Intel Turbo Boost technology delivers dynamic extra power when you need it.
A:AnswerHi Cesar, I believe it can, it has 4 - USB ports and 1 - USB 3.1 Type C Ports and I know for sure it can work with an external hard drive.
I bought this laptop and an external hard drive that I am using, see attached recommended product.
A:AnswerI don't know the reason it was refurbished. Case looks like new and it performs the way I expected it to. Guess time will tell. As far as extended warranty, I keep getting notification from HP about their extended warranty. Don't know the cost yet.
