I would suggest you to buy the Laptop from the official store. There you can find the latest updated laptops available in the category and can check it before buying. Although you could get a little more discount online. But many customers have reported issues with it, as if some faulty laptop arrives then the provider don't replace it.
- The processor should be i3 (8th generation onwards) OR i5 (7th generation onward)
- The 8 GB RAM works great. Although 4GB RAM can be good if processor is i5 (latest generation)
- Battery backup should be 5 hours.
