Dell’s disassembly method introduction [Tutorial]

Laptop computers As we all know, with the continuous advancement of computer technology, computers have become thinner and lighter, so laptop computers were born. Nowadays, business people and college students choose to use notebooks because they are thin, light and easy to carry. Laptops do have many advantages, but they also have many disadvantages, such as dust. If a laptop is used for a long time, dust will enter the fans and other parts inside, which seriously affects the operation of the computer. Therefore, laptops You have to disassemble and clean your laptop regularly. Let me take Dell as an example to introduce how to disassemble a laptop!

1. Tools used in the entire plan

Throughout the plan, we will use the tools in the picture, including screwdrivers, air blowers, brushes and It is best to have thermal conductive silicone grease. If other tools are not available, it will not affect our smooth progress.

 2. Temperature measurement

Due to the design factors of Dell pp38l, the left palm rest and air outlet of the whole machine should be relatively hot places. The author also measured these two locations. The standby temperature is still relatively high, especially the left palm rest. It is so hot when in standby. After long-term use, my left hand always sweats, which is really uncomfortable.

 3. Unplug the power supply

Since you want to disassemble the machine, you must develop good habits. In order to ensure the safety of the disassembly process, we must first unplug the power supply.

4. Remove the battery

It is also the same reason to remove the battery. Although batteries are generally safer, We still have to be careful, after all, it is for our own use, because it is not good if carelessness leads to tragedy. At this point, our preparations are complete. The next thing to do is to stretch out our hands, because IWe are about to start work.

2. Disassembly steps

1. Open the memory upgrade window

Before unscrewing other screws, it is best to remove the memory first and find the memory upgrade window and unscrew to open it.

2. Remove the memory module

Since the author has upgraded the memory of his 14R478 before, what you see is two memory modules with different colors. We open the buckle. Remove the memory stick. Unscrew the screw next to the memory compartment. The screw next to the memory compartment is used to fix the optical drive. After removing the memory, we need to remove the optical drive before proceeding to the next step of disassembly. After unscrewing this screw, hold the optical drive and pull it out gently, and the optical drive will be removed. After successfully removing the optical drive, we unscrewed all the screws that can be seen on the back of the fuselage one by one. The size and position of the machine screws were divided into different types to make it easier to install them back.

3. Remove the keyboard

Pay attention to the method when removing the keyboard. Due to the design characteristics of the 14R keyboard, the lower half of the slot is very deep, so you cannot violently pry it from the bottom. You need to lift four buckles from the top, and then the keyboard will be slowly pried up. Be careful not to be too violent in this step. Once you have mastered the method of opening the four buckles, you must also use force slowly. If you don't have professional tools at hand, you can use IC. After the keyboard is opened, don't take it off with force, because there are still cables connected underneath, so turn it over slowly. Removing the keyboard cable The cable slots of the 14R are all in the same mode. Before opening the card slot, you can easily pull out the locking cable by gently lifting it up. Do not use force to pull it out. So far, we have completely removed the keyboard. Now let’s disassemble the C side.

4. Remove the screen cables

After removing the keyboard, we will see many connected cables on the C surface. We need to remove them one by one. , the screen cable on the upper left side of the middle part has a special appearance. It is the screen cable, and there is a black auxiliary handle on it. We need to pinch the auxiliary handle and pull it up, and then the cable can be removed. . Remove other cables. The other cables are basically the same as the previous keyboard cables. You can remove the micro-locks and the cables can be easily pulled out.

5. Open the C side

In this step, in order to reduce scratches on the fuselage, be sure to use a special tool, or if you don’t have special tools, you can use IC cards instead of fingernails. The most important thing is to minimize damage to the fuselage. When prying open the C panel, pay attention to the order and method. Since there are 5 fixing slots on the upper end of the C panel, you must start from the bottom. After the lower and side cards are pried open, pull the entire panel downward and disengage the upper end from the five card slots, and the C panel will come down obediently. It will be difficult to pry it open at first. Once you open one buckle, you can just open it all at once. This step requires skill and not brute force.

6. Completely remove the C-side panel

Through the above steps, we have completely removed the C-side panel. Observe from the bottom of the panel to strengthen the overall position of the optical drive. A metal cover is also added for strength, the workmanship is quite good, and the wiring is also very neat. Now we are almost approaching the important part, follow me and continue to dismantle it. Find the location of the fan. By removing the C panel, we can fully see the motherboard. At the air outlet on the upper left side of the machine, we can see a major focus of this disassembly - the fan. Let's remove the fan. The fan is already covered with dust. After removing the cable covering it, we can see the dust accumulated inside through the pores of the fan. Since the fan and the motherboard are easily separated, we first remove the fan.

7. Unplug the fan power cord

In order not to get too excited and forget about it after removing the fan, you should unplug the fan power cord first.

8. The fan was successfully removed

Removing the fan is very simple, just unscrew the screws on both sides of the fan. Looking at the dusty fan, the author can't help but feel heartbroken. After all, I I still take good care of the 14R, but I don’t know where all the dust comes from. Therefore, friends who feel that they take good care of their computers and that there is no dust in their computers should also pay attention. In fact, no matter how much you take care of your computer or how clean the environment it is used in, it still needs to be opened and cleaned after about a year of use, otherwise it will seriously affect the use experience. and overall performance. At this point we have completely removed the fan.

Okay, the above is the disassembly procedure of Dell laptop introduced by the editor. The disassembly procedure of this computer is different from the general one. Computers are a little bit more difficult, so I will give you a more detailed introduction. Just read it a few times and remember the sequence of disassembly.In fact, everyone knows that the most important thing when disassembling a computer is to remember the sequence and do it gently to avoid damage to computer parts. Of course, the notebook itself is very good in terms of configuration and performance. The consumers are very satisfied.
