FAQ

Frequently asked questions

What you most want to know about Laptop Motherboard Chip-Level Repair in Nanxiang

Can it still be repaired after liquid damage?

The sooner the better. Power off and don't keep powering it on; after stripping and de-corrosion most can be saved. Even with heavy board damage, drive data can usually be recovered separately.

How long does it take?

On-site fixes are done immediately; rework-station jobs usually take 1–3 working days, and we give an estimate when we take it on.

Another shop said board replacement only — worth a second look?

Yes. Judgment and diagnostic depth differ. An independent diagnosis costs nothing extra: component repair if possible, board replacement only if genuinely necessary.

Is diagnosis charged?

On-site diagnosis is free; you approve the quote before any repair.

Will I lose data?

Anything involving storage is backed up or imaged first; suspect drives are assessed before work.

What if it can't be fixed?

No charge if it can't be fixed for technical reasons, and we explain the situation and options.
