CentralComputer.hk's professional engineering team covers all Hong Kong Island (Central, Wan Chai, Causeway Bay, North Point, etc.), Kowloon (Tsim Sha Tsui, Mong Kok, Kwun Tong, etc.), and the New Territories (Sha Tin, Tsuen Wan, Tseung Kwan O, etc.). Whether you're in a core business area or residential district, we provide timely on-site technical support.
Common questions about on-site computer repair pricing, duration, and data security answered. If you have further questions, feel free to contact us via phone or WhatsApp.
Our basic fee includes an inspection fee and parts cost. The inspection fee varies by area (HK Island, Kowloon, New Territories) and time. If repair is confirmed, the inspection fee is deductible from the repair cost. Standard on-site inspection fees are uniform across Hong Kong, with possible surcharges for remote areas like Tung Chung and outlying islands.
General system issues or parts replacement can typically be completed on-site within 1-2 hours. Repairs involving motherboard work or out-of-stock parts may take 1-3 business days. For SSD or RAM upgrades, we recommend allowing about 1-2 hours.
Professional integrity is our core value. We implement strict security measures when handling client data and can sign NDA agreements upon business client request. All repair processes prioritize protecting client data.
We provide on-site service Monday to Saturday 09:00-18:00. Weekends and holidays can also be arranged with advance booking. Non-business hours (after 7 PM and holidays) may incur additional surcharges, which will be explained when booking.
Practical guides from real customer cases, in Chinese and English.
One USB-C cable carrying a monitor, keyboard, mouse, and charging is wonderfully tidy — until it fails and everything on the desk dies at once, leaving you unsure whether the cable, the dock, the port, or a setting is at fault. This guide uses a reconnect-one-thing-at-a-time method: separate charging, video, and USB into three lines, then check cable specification, power wattage, and driver and firmware, and finally lists what you can safely fix yourself and what should stop and go in for inspection — instead of blindly buying another dock or another cable.
Read moreThe most embarrassing IT failure always appears one minute before a meeting: a black camera, a microphone nobody can hear, or a device that works in one app and fails in another. This guide uses a three-layer check — system layer, browser or app layer, then meeting-app layer — to separate a privacy setting, a permission, a wrongly selected device, and a hardware fault within ten minutes, plus a 60-second pre-meeting checklist, so you never troubleshoot live in front of a client again.
Read moreYour computer is doing nothing, yet the hard drive gives a soft click every so often — and the clicks stop when you copy files. Many people assume the drive is about to die. But idle clicking has two very different causes: a normal head-parking power-saving action, and a distress signal from heads that cannot find their track. This guide shows how to tell them apart using the click pattern and the SMART Load Cycle Count, and which situation means back up and stop immediately. Inspection first; a quote is provided after inspection.
Read moreA laptop closed on its dock, driving an external monitor as a desktop, keeps the desk tidy — but the machine keeps getting hotter, the fans never settle, and it occasionally stutters. Is the closed lid trapping the heat, or is it the dock placement, the workload, or a blocked vent? This guide explains why closed-lid mode runs hot, how a 30-second vent check separates the causes, and when you must open the lid again. Inspection first; a quote is provided after inspection.
Read moreThe same NVMe SSD boots and opens small files in a flash, yet copying tens of gigabytes or exporting video suddenly drops from high speed to a crawl, then slowly recovers. Often the drive is not failing — it is thermally throttling. This guide explains the throttling mechanism, how temperature readings and symptom patterns separate heat from other causes of slowness, and how heatsinks, case airflow, and firmware updates help, plus the signals that mean stop immediately. Inspection first; a quote is provided after inspection.
Read moreA visitor, courier, or temporary partner arrives and asks, "What is the Wi-Fi password?" Handing over the company network password is one of the most common — and most dangerous — habits in small businesses. This guide explains why visitors must never join the internal network, how a guest network is isolated, how QR codes and password rotation work, how bandwidth is limited, and the five most common mistakes. Inspection first; a quote is provided after inspection.
