It took three years for the notebook to die in blue screens, and it was hard to get a decent, basic computer repair center in 2026
What the hell is a chip-class panel working on
The most common problem with the long use of the mackey notebook is the welding and ageing of the bga chip on the main panel, which is not solved by changing the screen and adding memory. The maintenance centre no. 289 of tianbei is equipped with over 600,000 yuan of specialized equipment, such as a bga chip welder, a circuit board baker, a lcd binding machine, a oscillator and an ultrasound cleaner, to deal with such bottom chip failure。
For example, the aspire screen is dark and the keyboard is partially inoperable, and the break-in is the deoxidation of the drive chip. The engineer first removes the oxidation layer from the ultrasound scrubber, then uses the oscillator to measure the signal wave shape to confirm the route and finally re-plant the welding. It would be less than half of the cost of changing the main board directly, and the cycle would be two or three days without waiting for accessories。
Home serviceWhich areas are covered
The service points of the maintenance centres are highly covered, and they are accessible in the areas of ultra-shows, tianhe, bay, haigu, white cloud, yellow plum, handu xinhua, nan zheng, shang city and economic development areas. Government agencies, schools, factories, hotels and restaurants are available, and families come to the door and do not have to run with machines themselves。
The client of the tianhe office area dialed 020-2807802, and the engineer arrived that afternoon. The old area of yosumi bay generally responded within 48 hours, and engineers with accessories were able to travel a little further to xinhua and cheng city. An enterprise's annual insurance contract can be negotiated, and government agencies can match the procurement process。
Team configuration and engineer level
The centre currently has more than 20 experienced maintenance engineers, plus a total of 90 industry elites. These individuals are not at the level of change of memory strips, and bga refurbishment, lcd binding, circuit board testing can be operated independently, and in the short term, they have grown into new starters in the guangzhou maintenance industry and have trained a number of chip-level engineers。
The team provided long-term technical support to sony, toshi, dale, hewlett-packard, apple, union, hong ki, huashu, fang zheng, zhengqing, qinghua zhong, etc., and received spare parts as a first-hand channel, not as a disassembly bulk. The maintenance centre is constantly introducing new equipment, and the new light master plate in 2026 is more sophisticated and cannot be repaired。
What brands do you fix
In addition to the aspire and travelmate series of hong ki acer, it covers sony, toshi, matsushita, fujitung, samsung, dale, ibm, hewlett-packard, comber, apple, gateway, sharp, nec and other foreign brands, as well as united nations, fang jing, co-owner, tucah, min ki and others, and basic guangzhou notebooks are available for sale。
The layout of the different brand master chip varies widely, the macro-base and the interconnectivity definitions are completely different, and engineers need to adjust parameters to specific models. The circuit board detector at the maintenance centre automatically identifies the size and location of the chip, reduces miscalculation and allows for secondary malfunctions due to hand-searching of adjacent chips。
What about price and quality assurance
The chip-level panels are subject to a fee based on failure, not replacement. The main plate is dryed, the chip is replanted at two to three hundred and the keyboard is replaced. 30 dollars for the faisal river, 50 dollars for the bay of yusumi and 80 dollars for the remote areas. The pre-repair offer was fixed at no cost, and the re-loading of the win7 and the formation of a separate charge for the local area network was not tied to the main board。
The quality assurance policy is to be returned free of charge within three months of the same failure, with the replacement providing the original plant or compatibility for two years. The purpose of the maintenance centre is to be safe, economical and professional, to pursue reasonable prices and satisfactory services, and not to earn differentials in terms of information. It is a basic requirement to be anxious about the customer, and to be satisfied can be said in person。
What's the difference between street repairs and official sales
There's no bga welder at the street shop, and welding the chip can only suggest changing the whole panel, and you get over a thousand dollars in work. The official sales were made in the form of only one brand, which was not changed, and a large base of the main board was offered in thousands, queuing for a week. The maintenance centre follows an intermediate route, can be repaired at the chip level, cannot be replaced, and offers are transparent。
In 2026, there were many it practitioners in guangzhou, and there was a high probability that the notebook would be unchained for three or four years. Finding a repair point that is hard, priced and transparent, saves half of the official time, less than a street shop. The maintenance centre feeds on reputations and retrogressors, and customers will never come back once offered。
Do you have this hong ki fixed and then replaced it? I'll tell you what it's worth. It was felt useful to forward it to colleagues who had also been victims of computer abuse。
