It has similar spec to my current broken laptop. Instead of a i5, it comes with an i7 8550U, 8GB of RAM and 256GB storage. It is a renewed product, by the way. And it goes for around ₹24,000. Honestly, I feel like it is too expensive, considering how there are better spec laptops available.
I just got a used thinkpad t14s for $400. A bit more expensive than your budget, has non upgradable ram, non removable battery, but the cpu is newer generation so much faster than a t480. But if you don’t need something really powerful than a t480 would do.
