Xinhong Subdistrict, Minhang. Won't power on, blue screen, running slow, liquid damage, lost files — describe what you see and we send the nearest engineer. We arrive with tools and common spare parts, diagnose first and quote before we touch anything.
From one laptop to a whole office floor — one call covers it

Step-by-step testing of power, motherboard and GPU, with PSU, board and cooling parts replaced on site.
Book now
Screen, battery, keyboard and board tested one by one — including MacBooks. We tell you exactly where it fails.
Book now
We trace the fault down to the actual circuit. If a component can be replaced, we replace the component — not the whole board.
Book now
Genuine OS installed and activated, drivers complete, your usual software set up, and your files backed up before we start.
Book now
A read-only image is taken before any recovery, so nothing is made worse. Cost is confirmed before we start.

The cheapest way to make an old machine fast again. Most models are done the same visit.
Book nowThe calls we get most often, with how we judge and how we fix them
Power supply, board power stages, memory seating and the power-on circuit are checked in order, so we can tell power, board or OS apart.
Memory test, drive check, driver repair and temperature check. We do not swap parts before we know which one failed.
Drive health check and startup cleanup first, then RAM and SSD advice. Most machines do not need replacing.
Power it off and do not turn it on again. We strip, clean the corrosion and replace damaged parts — the sooner, the better the odds.
Cable, GPU and display settings are checked. Screen replacements are quoted by model and panel, fitting included.
A clicking drive is not spun up repeatedly. Anything storage-related gets imaged before recovery.
Internal cleaning, fresh thermal paste and better airflow bring temperatures back to normal.
Front-panel wiring, board headers and drivers are checked. Dry joints can be reworked at component level.
On-site diagnosis is free. The quote is itemised, and we start only after you approve it. If the same fault returns within 90 days, the rework is free.
The fault is traced to a circuit and a component. Screen, battery and keyboard are tested separately, and we explain every step.
Head swaps happen in a clean bench; boards get BGA rework and reballing instead of a full board swap.
Anything involving storage is imaged read-only first. Companies can sign an NDA.
Final cost follows the itemised quote on site. Nothing starts without your yes
