Re: Nothing? Surely you jest.
FYI in the gen 7 which I have the storage is very easily replaceable. Just be sure to get a single sided SSD.
The battery is also presumably user replaceable as it is held in with screws. Of course you would have to source the proper part.
And for the price, I have always been able to get Lenovo laptops for roughly 50% of the sticker price due to huge sales always occurring. So take the retail price as more of a guideline the gospel.
