You cannot upgrade soldered RAM after purchase — but Framework exists.

No. No major laptop manufacturer offers a service to upgrade soldered RAM after you buy the machine. Once it’s soldered, it’s permanent.

The closest you’ll find is Framework. Their laptops use modular RAM slots, so you can swap modules yourself — but that’s not a “manufacturer upgrade service.” You buy new sticks and install them. It’s easy, but it’s on you.

If you’re asking because you’re worried about future-proofing: buy a laptop with user-upgradeable RAM (like Framework or some older ThinkPads) or just max out the RAM at purchase. Soldered RAM is a one-time decision. There is no coming back.
