From a single device to a whole office, all handled the same way
The client used to call only when something broke, and faults kept recurring. After asset records and scheduled inspections, the number of service calls dropped noticeably.
The client moved into a new office in Lingang New Area, with devices and cabling to re-organize. We tested and numbered each device and delivered an equipment list at handover.
The same problem had been handled twice elsewhere without a fix. We re-diagnosed to find the real cause, and after repair it stayed stable for a week of observation.
What you most want to know about on-site service in Nanhui New
Yes. We source genuine or compatible consumables by model and install them on site.
Look at the repair cost first. Most small faults are tens to a couple hundred RMB, cheaper than replacing.
Yes, billed monthly by machine count, including upkeep and emergency repairs.
Most of the time, yes. Deleted, formatted and lost-partition cases have high success rates; hardware damage needs a read-only assessment first. We give you the rate and range before you decide.
No. Assessment is free and there is no charge if nothing is recovered — no hidden diagnostic fee either.
Powering it on lets the head scratch the platter, spreads bad sectors and overwrites recoverable data. Power it off — the sooner we handle it, the higher the success rate.
Describe the device and the symptoms; our technician brings the right tools and common parts. Diagnose first, quote after, and repair only once you approve.
