The repair cost is more than 3,000, which is half a year's tuition. If it's less, I can still afford it. It's really hard for my family to account for so much.

To put it bluntly, it's not worth spending money if you haven't taken advantage of it.

"I'm going to the toilet first, you watch!"

Lao Wu used his urine escape to dodge, and Ji Dongqing secretly scolded him for not taking responsibility. From now on, he can no longer do computer repair work, and he might ruin his own brand.

Turning on the HP host, Ji Dongqing carefully checked every point. Fortunately, the information contained a circuit diagram of the motherboard. Ji Dongqing checked the memory stick.

I didn't see anything wrong, so I put a magnifying glass on my eyes and carefully checked every point. There were no weak solder points.

Then he started to take out the circuit diagram and measured various points with a multimeter. After half an hour, Ji Dongqing finally found the abnormal voltage point.

"Sure enough, there is a breaking point, let's find it!"

Looking behind the golden finger, Ji Dongqing held a magnifying glass between his eyes and searched point by point. Finally he found the abnormal breakpoint and quickly circled it with a red pen.

Enameled wire, solder, welding gun.

"call!"

After the repair was completed, Ji Dongqing checked again and found that the voltage and resistance at all points were normal. Ji Dongqing wiped the sweat from his forehead.

"It's finally okay, my mom, I'm so worried!"

After turning on the computer, the HP computer finally turned on. The school beauty was excited for a while. Ji Dongqing wanted to see other information, but the computer had a password, so he gave up.

"what happened?"

"There was a problem with this motherboard when it was first produced. The materials used were insufficient and the high current burned for a long time and it burned out. You see, this is leading to the CPU..."

Ji Dongqing tried his best to avoid his fault and asked the other party to test it. Only when there was no problem did he put it back into the chassis.

"You are really professional. How much does it cost? Are you a student of our school?"

"Yes, I am from the mechanical and electrical department, and I have received 800 yuan!"

"Why is it so expensive?"

The school beauty thought it could be done for just a few dozen yuan, but she immediately frowned when she heard Ji Dongqing's price.

"Beauty, I'm a welding major. If it takes them three days to find these few solder joints, I'll lose. And we can't find three people in our school to weld in such a small place! This is a technical job. From now on,

If you have any problems with your computer, come to me for warranty service!"

"Okay, since you look so professional, you have to give me a novel. I like this one!"

Seeing Ji Dongqing's serious look, the school beauty knew that he was not lying, so she paid 800 yuan and waved her hand with a new online novel.

"There's no need to give it away. The school girls in our bookstore can read it as they please. It's free of charge! Just bring us some customers!"

"Deal, I'll take these two copies too!"

"Okay, He, you can carry the machine with the school beauty, send it to a local experiment, and then come back if everything is fine!"

"okay!"

Xiaohe was also willing to date beautiful women, so he went out with the school beauty and came back within a few minutes.

"Oh, my rich second-generation boyfriend is right here. Brother Dongqing, I guess if you don't fix it today, our store will be smashed. Xiaotao is too careless and hides himself when he gets into trouble.

Why didn’t you tell us!”

Entering the house, Xiao He whispered in Ji Dongqing's ear. Ji Dongqing couldn't help but frown, thinking that Lao Wu was really here to play, since this way, you won't have a job in the future.

In mid-to-late June, the weather began to get hot and hot, construction sites began to take a break for summer vacation, and the busyness of the repair shop began to ease. Except for the three artillery machines, several mechanics began to return, and Ji Dongqing took a breath.

Only then did Ji Dongqing have time to look at the Yamaha 125 motorcycle from Jiamusi, and the mailed parts were basically in place.

The old trick is to use a high-pressure water gun to clean the car first. All the dust on it will be blown away by the wind, and the body will gradually reveal its true identity.

"Brother Dongqing, where did you buy this thing?"

Looking at the tattered Yamaha, several workers squatted there with cigarettes in their hands, looking at Ji Dongqing with squinted eyes.

"It's a friend's, I'll use it for fun, help me push the tool cart over!"

"Buzz!"

As the wind cannon trembled, the screws were pulled out one by one, and the workers spontaneously gathered around to help Ji Dongqing dismantle it.

Within an hour, the venue was covered with Yamaha parts, and the wheel hubs and handlebars were turned into parts.

Because the car had crashed, Ji Dongqing arranged for two workers to start flattening the lap, replacing inappropriate parts, and marking the damaged areas for Ji Dongqing to weld and repair.

After everything was finished, Ji Dongqing arranged for someone to polish the frame, and all the small workpieces that were not afraid of deformation were thrown into the sandblasting machine.

After the distribution was completed, Ji Dongqing found a table and began to dismantle the Yamaha engine.

I have to admire the original factory workmanship. Except for a few chipped radiator fins on the outer engine case, the inside of the engine is intact.

Ji Dongqing dismantled a table of clutches, connecting rods and other things in minutes, giving the worker a headache just looking at them.

"You two wash this side, you two wash this side, and then I wash these!"

There is no carbon deposits or scratches inside the engine, which proves that the machine was originally in good condition, which saves a lot of trouble.

Ji Dongqing was worried that the engine would be deformed, so he found a meter rod and a meter stand and made a circle against the inner ring surface of the cylinder, and it was all within the tolerance range.

To ensure safety, Ji Dongqing replaced the piston rings.

Then Ji Dongqing began to assemble, from the combustion chamber to the chain...

"Damn it, I won't be able to learn it even if you give me another ten years. Why would Brother Dongqing, a college student, care about this thing?"

"That's right, shouldn't college students sit in offices?"

"Holy shit, if all college students are like Brother Dongqing, will we still have food to eat in the future? Can we endure hardship and still know technology?"

"That's right. Fortunately, the vast majority of college students are nothing!"

"I have to admire the quality of these college students. When Lao Li was here, he would order things all day long and curse at others. Look at him!"

"Old Li seems to be coming back!"

"You won't serve him even when you come back. He's so numb that he's so quick to attack us. He treats us like livestock!"

Several workers looked at Ji Dongqing assembling the engine from a distance, with envy in their eyes. Although Ji Dongqing was focused, he still heard clearly.

It is said that the so-called Master Li has been working for 20 years. He was a big boss when he was in a state-owned enterprise. He seems to have come from a certain main engine factory and is a good batch.

There are ancestors in the repair shop, and you have to be ready when the other party comes back.

As the saying goes, there is no room for two tigers in one mountain. This concept is deeply ingrained in the minds of every older generation.

Translated, it means that the old guy doesn't have much ability, and strives to squeeze out anyone who is more capable than himself, so as to achieve self-dominance.

The primer of the frame had dried. Ji Dongqing took a look at the fenders, adjusted a color he liked, and then started spray painting. When the workers went to dry it, Ji Dongqing placed the replaced combustion chamber on the table.
Chapter completed!
