FAQ

Frequently asked questions

What you most want to know about on-site service in Chengjiaqiao

How do you verify when done?

We walk-test speeds in every room, check signal strength and handoff, and finish only when it meets the bar.

What if I want to add APs later?

The plan leaves expansion headroom, and you get the point map and accounts, so later adds are done straight off the drawing.

When is chip-level repair needed?

No response to the power button, liquid damage, black/distorted screen, won't charge, short circuits — these may all need it. Free on-site diagnosis locates the fault, then we tell you whether to repair components or replace the board.

Is repairing or replacing the board cheaper?

Most component-level repairs are quoted far below board replacement. If it's genuinely unrepairable, we'll say so clearly and let you decide whether to replace or go another route.

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.
