FAQ

Frequently asked questions

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

Will it be stable? Is there a warranty?

Repair warranty is 90 days. Before handover we run power aging and stress tests, photograph before and after, and list replaced parts honestly on the invoice.

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.
