Dell XPS 13, they have good battery life, run windows, and is powerful enough to run Roblox.

Asus zenbook, powerful, good screen, okay battery life

Hp pavilion plus, powerful, decent battery, great screen

Lenovo ideapad 5 and the dell inspiron are good laptops too. I know could name off over a dozen good laptops, these are 5 good ones, I think would be a good choice.

My toshiba satellite c55, had it for 9 years. It’s slow, but still good for web applications.
