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.
Check the display cable, video memory and GPU core power.

A few typical scenarios by service type below
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 Tianlin, 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 software companies client working in Hengshan Road 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 hospital departments client in Tianlin 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.
What you most want to know about on-site service in Shanghai
Yes, billed monthly by machine count, including upkeep and emergency repairs.
Most of the time, yes. Ordinary broadband doesn't allow outside access to the intranet by default, and exposing ports directly is risky. The solution uses an encrypted tunnel to safely open the intranet to designated people.
Windows, Mac, phones and tablets. Desktops and laptops just need the client installed; staff can check approvals and documents on their phones too.
No. On-site work starts by looking at the existing structure and bandwidth, and we schedule the switch after hours or on weekends, testing each part before handover.
Access runs over an encrypted tunnel, permissions are tiered by role, access is logged, and anomalous logins trigger alerts. Data never sits on third-party platforms — it stays on your own equipment.
Up to 10 users generally from RMB 1500, 10–50 users from RMB 3000, and multi-site by site count. We assess your network for free and give you a plan and quote to confirm.
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.
