preface

As the matter escalated, on February 13, Lenovo's official Xiaoxin Weibo account responded to the incident with an article titled "Xiaoxin Light and Thin Notebook Low-Temperature Solder Paste Soldering Technology Description" (hereinafter referred to as the "Description"). The document stated that low-temperature solder paste soldering is a mature and more environmentally friendly technology for electronic product production lines that meets national and international standards. It also indicated that, based on after-sales data from Xiaoxin Light and Thin Notebooks over the years, there is no difference in repair rates between models using low-temperature solder paste soldering technology and models using room-temperature solder soldering technology.

First

I myself use a Lenovo Xiaoxin computer. I bought it from JD.com's self-operated flagship store in November last year (2022). The model is Xiaoxin 14 PRO-IAH5R, and the price is 6199 (I personally feel that this price is reasonable). My first impression of it is that it is light, too light. According to official data, the 14Pro weighs 1.3kg, roughly the same as the weight of the 2020 MacBook Air. Even with a 100W gallium nitride charger, its portability and thinness are beyond doubt.

Secondly

Regarding this low-temperature tin incident, I do not believe it is part of Lenovo's planned scrapping. After watching the video of a laptop repair guy on Bilibili (I'm a fan of his), I found that most of the problems were with AMD platform machines. As is well known, AMD is notoriously hot, and some of the machines that undergo empty soldering are caused by high-temperature desoldering of on-board memory. This may be due to the unreasonable design of the heat dissipation structure at the time. Among the Intel models affected, I analyzed that it was because Lenovo used too much vinyl, which caused the CPU to be fixed. When the motherboard deformed due to the shaking of the computer, the CPU could not move, causing the solder ball to be misaligned. So this gives us a lesson:Don't shake your computer unless necessary. Be careful to hold it firmly.。 Therefore, I believe it is a design flaw.

in the end

What if it happens to you? My advice is to try not to contact Lenovo after-sales service. In the two months since I bought it, I've realized that Lenovo's after-sales service is exceptionally poor. I can say that some of the after-sales engineers' understanding of computers and their problem-solving methods are not even as good as some of my classmates. So, if you encounter this problem, it seems you can get it repaired for free under warranty (?). If it's out of warranty, go find a repair technician you're familiar with in a computer store. They might only charge a labor fee to resolder the unsoldered parts. Lenovo's after-sales service will directly replace the motherboard for you.I need 1000Then the price would be a bit high.

In conclusion, I do not believe that the "low-temperature tin incident" was part of Lenovo's planned scrapping; it may simply be caused by a design flaw. Secondly, to avoid these problems as much as possible, you'd better hold on tight. Finally, if you get scammed, just go through the warranty and find a repairman to fix it. There's really no need to send it to official after-sales service (waves).
