A standard repair shop can't fix soldered RAM.

No, not reliably. Soldered RAM means those memory chips are part of the motherboard. A standard laptop repair shop — the kind that swaps screens and batteries — doesn’t have the gear or the skill for that job.

Fixing soldered RAM requires a rework station, precise heat profiles, and the ability to reball tiny BGA chips. That’s specialist territory. Even then, it’s hit or miss. The failure is often in the motherboard itself, not just the chip, so a replacement is the smarter move.

If your laptop has soldered RAM that dies, the practical fix is a new motherboard or a new laptop. Don’t waste time and money on a shop that promises to “reflow” it — that’s a temporary bodge at best.
