Thank you all for your valuable insights and assistance. I plan to take the next few days to explore refurbished laptops online, based on the advice you've provided. Once again, a big thank you to each one of you for your help!
Look for the business class models, for example Dell Latitude, HP EliteBook because they are durable and their components can be accessed easily even if you can change with SSD on your own if you want to increase the size of memory.
I don't know how the quality of refurbished products but the offline store is the best to buy such things, I remember once I bought Latitude when my PC needed to be repaired which took a week so I bought a refurbished laptop from the guy to do my things and surprisingly it still works. I don't know if the performance is still up to the level or not cause never used it for performance-related tasks but it runs even today that matters.
