Strip and clean corrosion, replace damaged components, preserve data where possible.
Circuit-level diagnosis to find the short, avoid further damage from more power.
Check BIOS, EC and bridge chip; reflash firmware if needed.
We do an independent diagnosis first — component repair if possible, board replacement only if genuinely necessary.
Test the battery, charge/discharge circuit and detection circuit.
Usually dry joints or aging components; redo soldering and run long stress tests.

A few typical scenarios by service type below
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 financial institutions client working in Jinqiao Export Zone 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.
A chip and biotech firms client in Lingang New Area 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 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 Shanghai
Most cases just need one access device on the existing network; we assess first.
No — accounts are revoked the same day per process, with auditable access records.
Yes. Read-only or read-write permissions by role.
Yes — add accounts and assign permissions per the process.
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.
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.
