In order to enable everyone to purchase products with higher cost-effectiveness, we use a combination of routine quality inspection and in-depth quality inspection to present transparent information on the condition of the products to the greatest extent possible.
What are the common problems with computers?
Regarding common issues such as whether the second-hand laptop is an original system, whether there are any issues with its functionality, and whether the machine has been refurbished, we have conducted at least 6 quality inspection stages and multiple processes in terms of functionality, appearance, and disassembly to truthfully present the product situation in the inspection and evaluation report.
01 System configuration and manual inspection to solve system problems to the greatest extent possible
In order to avoid system issues such as sudden shutdown or unresponsiveness of the machines received by users, we strictly follow the operation of system restoration or upgrading the system through official channels in the first step of quality inspection, and try to ensure that more than 70% of the machines can use the original system. And the remaining 30% of the machines may not be able to be updated due to the old system. We will conduct manual checks on their operating systems to ensure that the system functions properly.
02 Beautiful Machine Assistant, Assist in Function Detection
In order to accurately and efficiently complete the standardized quality inspection process for routine functions, the transfer team has independently developed a machine inspection system. This application conducts 12 detection programs for wireless functions, cameras, microphones, data interfaces, keyboards, touchpads, fingerprint recognition, screen display, heat dissipation, and other functions to ensure coverage of the laptop’s functional usage scenarios. For example:
Appearance inspection: including scratches, bumps, wear/paint peeling, and fragmentation. For example, for scratch inspection, we will first use professional cleaning tools to wipe the back and frame of the screen, and then use professional tools to measure defects and judge the quality.
Although the quality inspection center has established a strict set of quality standards, users may still have misunderstandings when viewing quality inspection reports. Therefore, we will provide a large number of detailed defect images taken in real time for users to make decisions and reference.
Keyboard inspection: In addition to inspecting the appearance of the keyboard for paint wear and reflection, missing keys, and key detachment, we also inspect the letter input function, sensitivity, elasticity, and other functions; By conducting a comprehensive inspection of the appearance and function of the keyboard, it is ensured that the second-hand laptop keyboard received by users has good input performance and user experience on the basis of intact appearance.
Our self-developed machine verification system has significantly improved the accuracy of quality inspection, and its privacy clearance ability has also obtained international certification from ADISA.
03 Dismantling and inspection, checking for private repairs and replacement of accessories
Firstly, visually inspect to determine if there is any disassembly or repair: quality inspectors will carefully inspect the screen frame and screws on the back of the machine to look for possible signs of disassembly or repair.
Secondly, the computer will undergo disassembly inspection: after disassembling the machine, quality inspectors will carefully observe the following details:
- Motherboard screws: Carefully observe whether there are any signs of twisting on the screws on the motherboard, and check whether the original factory warranty label on the screws is intact;
- Mainboard repair traces: Carefully inspect the motherboard for welding or other repair traces;
- Main board and rear shell: The quality inspector will also pay attention to whether there are any signs of water ingress on the rear shell of the main board. If the machine has been exposed to water before, it usually leaves obvious signs such as watermarks, mold, or blackening on the motherboard.
Finally, for the motherboard of the laptop, we will also take photos and archive them as evidence to prevent potential quality disputes.
04 Clearing Privacy to Prevent Information Leakage
In order to ensure that the privacy of the photos, videos, passwords, and other information used by users is cleared, we have included privacy clearance in the quality inspection process to avoid potential disputes such as privacy leakage.
05 Re inspection and spot check, providing multiple guarantees
In order to ensure the multiple reliability of product quality, we have taken manual re inspection and spot check measures before shipment:
Manual re inspection: The machine undergoes manual re inspection before shipment, including careful inspection of battery charging to prevent issues such as insufficient battery capacity.
Spot check and testing: In addition to manual re inspection, we will also conduct spot checks and testing on some products. This type of spot check will select a certain proportion of products for stricter testing to prevent system crashes and other issues in rare cases.
Through manual re inspection and spot checks, multiple reliable guarantees are provided for the quality of products.
06 Professional tools for deep cleaning
After the verification process is completed, we will use professional equipment to perform a deep cleaning of the machine. For example, using a professional air gun to clean dust, etc.
How to troubleshoot hidden computer problems?
Routine quality inspection has identified most common computer issues; However, as the usage time increases, some low configuration laptops may experience hidden problems such as machine heat, screen display, and even abnormal shutdown, which are generally difficult to detect; In order to ensure a second-hand user experience, we reproduce hidden disease problems through in-depth quality inspection. Products with such problems will be notified and returned to the user. For example:
Regarding the issue of blue screen, crashes, freezes, and automatic shutdown: Our Beautiful Machine Assistant is equipped with a pressure testing function to detect and check the performance of the device to the maximum extent possible.
For fan detection, especially for gaming laptops, we will perform the following steps during pressure testing to check the normal operation and heat dissipation effect of the fan:
- Observe the operation of the fan: During the pressure test, we will carefully observe whether the fan is running normally, whether there is any whining or abnormal noise.
- Check the cooling effect of the fan: Determine the cooling effect of the system by sensing the temperature of the air blown out by the fan. If the wind blown by the fan is significantly cooler, it may indicate that there is a problem with heat dissipation, such as poor contact of the heat dissipation copper pipe.
Regarding screen axis opening and closing: We have conducted multiple studies and conducted detailed inspections on several aspects during the opening and closing process:
- Is it difficult to open and close: By repeatedly opening and closing the screen axis of the notebook, observe and feel whether there is any difficulty in opening and closing.
- Abnormal noise detection: Carefully check whether there is any abnormal noise, such as noise or friction, during the opening and closing process of the screen shaft.
- Check for any gaps after closing: We will check for any gaps between the screen and the body of the laptop after closing.
- Screen dark disease detection: We also check the screen for blackening, flickering, or other dark disease problems at various angles and positions based on the size of the opening and closing degree.
Due to the non-standard characteristics of second-hand products, if there are usage problems after receiving, in order to ensure your long-term experience, the vast majority of official inspection products at CheChe can enjoy a 7-day no reason return and platform warranty service.
