I have a budget of around $750 and I expect to be able to code in it. I honestly have not much idea what the ideal requirement of a laptop for a college student should be, which is why I am asking here to get an estimate of the specs I should be considering while choosing one. I would advice against naming any specific laptop as I have no guarantee of its availability in my region.
You can code pretty much with every laptop.
ThinkPad is always a solid choice.
It seems to me that the quality of Thinkpads have decreased the past few years, though I would still choose that over a Dell or HP. Thinkpads are best when buying used from companies replacing their computer fleet.
