Pretty much any pc over 500$ can run minecraft at around 60fps. I don't really know many specific models, but I'll give you some tips on what your laptop should have to run well (these are just recommendations, you don't have to follow them word for word
).
You really only need to worry about these two things.
1. An intel i5 processor (you can get away with an i3, but i5's are a bit smoother)
2. At least 4gb of ram
as far as storage and graphics go, 500gb's is plenty if you're not gonna put a lot on it. And pretty much all laptops around 500$ are just gonna have integrated graphics. Which isn't the greatest, but it gets the job done. I can play Skyrim, Batman Arkham Asylum, and Bioshock fine, just on lower settings. So as long as you weren't hoping to run shaders, you'll be just fine.
Also, here are some companies I've found to make pretty good laptops (I'm sure other companies are probably just as good, but I've only had experience with these companies). Acer, Asus (these companies have been known to make good gaming laptops, but their pretty expensive), and Lenovo.
That's all I've got for now, but if you have any questions, feel free to ask me
Edit: I would also recommend getting optifine (if you don't already use it that is lol), it helps out a lot with optimizing the graphics.
