Looking for a uni laptop, Laptop Request

Total budget and country of purchase:

Poland, 2500 pln, preferably under 2000 ( ~500 eur max?)

Are you open to refurbs/used?

Yes, but need to be good quality (not break down after a week so looking for a reliable seller), mostly looking for refurbished with at most slight damage on the outside (no post water tragedies)

How would you prioritize form factor (ultrabook, 2-in-1, etc.), build quality, performance, and battery life?

I'm looking for a 2nd laptop, for uni, needs enough battery life for 8~10h of word/excel with no internet, or can be charged from powerbank, touchscreen would be nice Performance is just for firefox/microsoft 365, i have a pc

How important is weight and thinness to you?

Needs to be thinner/smaller, doesnt need to be super light just not big

Do you have a preferred screen size? If indifferent, put N/A.

Not super big, else i dont care

Are you doing any CAD/video editing/photo editing/gaming? List which programs/games you desire to run.

Might need to run: sql, microsoft 365 (excel / word), firefox with at least 20 tabs, adobe for pdfs, easier/smaller programs.

If you're gaming, do you have certain games you want to play? At what settings and FPS do you want?

For this one maybe chess or go, not seeing myself playing on it

Any specific requirements such as good keyboard, reliable build quality, touch-screen, finger-print reader, optical drive or good input devices (keyboard/touchpad)?

Good keyboard, resilient (ill be taking it to lectures), touch screen nice but not necessary, either 1tb ssd or place to add a ssd stick, quiet!! this is important, 16ram (or place to add ram stick)

Leave any finishing thoughts here that you may feel are necessary and beneficial to the discussion.

Looking for a cheaper but alright laptop that will work for uni and some uni programs, maybe heavier databases but not expecting anything very heavy, mostly word / excel If someone has a good source from where to get refurbished laptops

Thanks for any advice / reccomendations !!
