Reballing soldered RAM will cost you $150–$300 and void the warranty.

You’re looking at $150 to $300 for a reputable shop, and yes, any physical rework like this will void your remaining warranty. Manufacturers treat soldered RAM as part of the motherboard — you crack it open and start reballing, that warranty sticker (or lack thereof) doesn’t matter. They can see the work.

Why the cost? Reballing requires a BGA rework station, skilled labor, and there’s real risk of killing the board entirely. Cheap shops might quote under $100, but I wouldn’t trust that with a 2021–2023 laptop unless they have solid reviews. The real question is whether it’s worth it — often a used replacement laptop or a new one with socketed RAM makes more sense financially.

If your laptop is still under warranty, fight for a claim first. Many manufacturers will replace the whole board if the RAM fails, which is free. Don’t reball unless you’re out of warranty and the repair is significantly cheaper than a new laptop (which it rarely is).
