Real scenarios from this area, for your reference
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 Waigang, 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.

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.
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.
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.
