ELI5: How does US customs know if an expensive item I have, like a new laptop, was bought before I left vs. brought back undeclared?

Unless it’s in new packaging I don’t think they would ask. It’s possible they could ask for proof of purchase, but you can always claim it was private sale.
Generally they don’t, but if you want to have some insurance, you can pre-register your expensive items before you leave the US so there’s no trouble when you return. You can get a certificate of registration at your local Customs and Border Protection office, and fill it out.
If you bought your expensive laptop on your trip, all I can say is make sure it shows evidence of being a used item, not pristine new.
They don’t, at least not from a casual glance at it, but that doesn’t meant they can’t figure it out with a detailed examination. Some manufacturers embed country of sale information in serial numbers, some model numbers are only available in certain countries or regions, the software on a computer and data stored in its memory can indicate at least a country of manufacture if not sale. And your rights at a point of entry are substantially weaker than your rights once you’re actually in the country, so you have far less protections available to you if customs believes you’re failing to declare your device. Effectively this means that if they suspect the device was purchased out of country and not declared, they can (and will) confiscate it. Maybe months or even years later you’ll be able to win a claim against them and get your device returned, but that’s about as good as it will get for you.
They don’t know, so they put the onus on you to prove it, so you should be able to produce receipts or other evidence
In practice, they generally take a path of lower resistance; assume that most people are either honest or only infringing in minor ways not worth the effort of cracking down on, but if you do end up in a situation where your imports are questioned, they’ll be expecting you to have the evidence, and they hold the cards so it’s best to have the evidence they expect
To prove you owned something before leaving the country and avoid paying duties when coming back, you can register the items at the nearest CBP office or international airport by requesting a Certificate of Registration (CBP Form 4457) and having the items (including serial numbers) handy. You need to do this before you leave.
I don’t think they care about a single laptop. If you had 3+ brand new laptops, they might get curious.
They don’t.
It’s not for this but I heard on a Planet Money podcast an interesting solution to this problem if they were ever to institute a wealth tax. Basically, you can declare the item with any value you want but you also agree to sell it at that price. Or something like that. I thought that was a fun trick.
The way it works with friends in South America that used to buy electronics in the US to bring home due to the tariffs making it impossibly expensive in their home countries was that they would just use it and get rid of boxes. That’s it. Border and customs don’t have the time to police that.
We used to sell A LOT of cameras, computers, and video cameras in downtown Miami before Argentina and Brazil reduced their high import taxes on stuff like that. People would take time away from their vacation to go shopping for that stuff to the point that it was a reduction in the vacation costs from savings.
We would in most cases also provide them with a reduced cost invoice in case they get caught and have to pay import duty. It would be over a much reduced bill.
