A:AnswerThe battery it comes with pribably lasts 7 hours under modest usage. In any event it is not a “choosable battery.” If you are a bit technical-capable, I suppose you could buy one extra of the standard battery, charge up both batteries at home, put the extra battery in backpack, and bring along suitable screwdriver to remove laptop bottom and swap to fresh battery when needed. That’s a lot of monkey business though.
A:AnswerIt is available again as a 2025 Black Friday special but your local dealer may or may not stock it. But right now (Black Saturday) it shows as orderable. Must have sold well so BB ordered more.
A:AnswerThis laptop likely lacks a Thunderbolt port. Perhaps you bought a similar model with an Intel CPU? Most laptops with Ryzen CPUs would have a USB-C 4 port instead, which has similar capabilities. As far as I know, no USB-C 4 port here. (But Best Buy often errs on specs, so anyone who owns one might contradict me.)
