CPU desoldering is a very normal occurrence.
Even in Xing Baohua's time, what machine didn't detach from the solder joints? It wasn't just laptops; even desktop computers would detach from the solder joints.
Especially with AMD processors, you can see the gold pins when you lift the CPU socket. This is caused by overheating and CPU overload.
This is actually a problem, but it can be broken down into two parts. First, we need to rule out fan issues before considering the CPU. If you're handy, you can resolder it yourself.
If you weld it crookedly, just blow it down with a blower and keep welding. This thing isn't that precious, is it? People don't do it much, it's just that they don't have the tools on hand.
Most CPU overload issues are caused by software. For example, performance testing software like LuMaster and TuTu can unnecessarily overload the CPU, causing a sharp rise in temperature.
Another type is software that calculates the amount of data. It lets the computer process a huge amount of data until the CPU gets hot enough to melt and shift the solder.
My own CPU is so rubbish! Who would bother to test their CPU with large amounts of data? Isn't that just asking for trouble?
Xing Baohua's first thought was to have his competitors test the performance of his CPU and obtain detailed data.
Since you're in the same industry, you can just solder it back yourself. Why bother the after-sales service?
After a short wait, the lab engineers restored the data, and Xing Baohua had someone open it to check; it was indeed the testing software.
What ordinary gamer doesn't cherish their computer? Anyone who dares to tinker with their computer like this is a tough nut to crack! Of course, they'd only do this if the government were paying for it.
Xing Baohua also suffered from the warranty. In order to maintain the brand and provide good service, Xing Baohua promised to replace the product if there was a quality problem within three months, provide free repair within one year, and only charge the technician's labor fee if there was a hardware quality problem within three years.
It hasn't even been a month since it was released, and the CPU has already desoldered. If someone makes a fuss about it, DaMi won't even have a chance to explain.
There's no way to explain this as the user using the computer roughly; the more you try to explain, the more it seems like you're shirking responsibility.
Damn it, this is a real loss that I had to swallow in silence!
Try the new machine again with the other party's testing software to see how they use his computer. The engineer had just started it when Xing Baohua called a halt.
Make several copies of the test software, use one machine to run the tests, and then find several other machines to disassemble the software.
Xing Baohua felt he had met another talented person. He had never seen this testing software before. Either the other party had ported it over, or this expert had written it himself in JAP format based on JAVA.
The analysis results came out quickly: the software was ported, and the other party had also added some of their own touches. The kernel was very similar to a foreign testing software.
The cause of the CPU overheating from this software has been identified; many of the data points were not changed by that expert!
It's also a 32-bit CPU, so it can be used to test other CPUs of the same bitness, at least those have several times more transistors than Loongson. Besides, this thing is for testing complex instructions.
Loongson is a simplified instruction set chip. If you test its tiny device with massive amounts of data, how can it not break?
This is equivalent to a small Alto trying to haul a load of over ten tons of cargo at high speed; it's no wonder the engine explodes!
Xing Baohua went outside for a smoke and asked the engineer to copy down the software name and some code. He then sent a repair manual to the after-sales department, describing the characteristics of CPU desoldering and instructing the repair personnel on how to solder it.
They even recorded a video of the engineer soldering the CPU and sent it to global after-sales service on a CD. By the way, I would like to add that CPUs that are desoldered due to human-induced violent testing will not be covered under warranty. They can repair it, but at their own expense.
The pricing standards are determined by the after-sales technicians themselves.
This led to a consumer writing to the rice company six months later to complain about the arbitrary charges for after-sales service in their area; the cost of soldering on a CPU was almost the same as buying a new machine.
Xing Baohua glanced at the letter and threw it away. It wasn't his own money, why was he so upset? If he dared to test the machine, why didn't he solder it back himself? He could buy a good piece of equipment for less than fifty yuan.
If you can solder electronic components, you can solder chips. It's just that there are more solder points on the chip, right? You can solder chips with 20 or more pins, but you can't solder chips with 40 or more pins. Who can you blame for not being skilled enough?
Of course, this incident also made it into the local newspaper, and the after-sales service had to apologize and offer a 50% discount to settle the matter.
Xiao Tianna's team is cracking the Japanese remote control program, but the system prohibits the use of this testing software, so they'll have to wait until he's finished.
This software has a major flaw: it bypasses the power management system and temperature control system.
This is why the machine doesn't shut down even when it overheats. After all, for testing, the power needs to be turned up to the maximum and the temperature needs to be raised to the limit to get the results.
It was detected during testing, and the CPU is now unusable.
An internal registration group has been set up as a defense. When the other party tries to install and register, a small dialog box will pop up, prohibiting the installation. Forcing the installation will cause irreversible damage to the CPU.
If you can scare him, great; if not, he'll have to pay for it himself anyway.
After these broken machines are returned to the factory for repair, they are wiped with alcohol, repackaged, and sold.
It's just not going to be listed on the market; it will be reserved for those who try to get the machines through connections.
Since returning to central Shandong, Xing Baohua has been constantly busy, coming straight from the laboratory to the small household appliance R&D center.
