From a single device to a whole office, all handled the same way
A sports-training centers client in North Sichuan Road had a device go down suddenly. We judged the fault direction by phone, and our technician brought matching parts and completed repair and testing the same day.
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 North Sichuan Road, 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.
The client needed to operate normally during the day, so we came after hours. Several staff worked in parallel and finished testing and cleanup before closing.
A old-community property client working in Tilanqiao had devices failing and holding up progress. We visited by appointment and handled them in groups, restoring normal use the same day and logging the devices into a table.

Anything involving storage is backed up or imaged first; suspect drives are assessed before work.
No charge if it can't be fixed for technical reasons, and we explain the situation and options.
Genuine or compatible parts per your choice, with price and warranty on the invoice.
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.
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.
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.
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.
