From a single device to a whole office, all handled the same way

The client moved into a new office in Jiangwan, 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.
What you most want to know about on-site service in Liangcheng
Test records (runtime, ground resistance, alarm test), a rack label table and before/after photos, with a 1-year warranty.
Critical equipment stays powered where possible; required downtime is agreed in advance.
Generally 3–5 years; we test internal resistance during inspection and remind you early.
Priced by device count and scope — PCs are generally RMB 30–80/device/mo, servers and network billed separately. We do a free assessment and give you a list and quote.
Callback is usually within 30 minutes; on-site visits are scheduled by urgency, most same-day. Remote-fixable issues are handled remotely first.
We can set up a VPN remote-work solution: staff connect to the office network over an encrypted tunnel, and file sharing, ERP and OA are all accessible securely. It's customized by headcount and current network, and supports desktops and laptops.
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.
