Screen distortion, black screens and no-power from dry GPU or bridge-chip joints are reballed on a rework station, with cooling improved at the same time.

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 eco-agriculture firms client working in Hengsha Island 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 guesthouses and resorts client in Baozhen 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 Baozhen, with devices and cabling to re-organize. We tested and numbered each device and delivered an equipment list at handover.
What you most want to know about Laptop Motherboard Chip-Level Repair in Chongming
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.
On-site fixes are done immediately; rework-station jobs usually take 1–3 working days, and we give an estimate when we take it on.
Yes. Judgment and diagnostic depth differ. An independent diagnosis costs nothing extra: component repair if possible, board replacement only if genuinely necessary.
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.
