The 24V power adapter manufacturer tells you that many people don’t know how to repair the power adapter. Let’s take a look at it together.
First, if there is a problem with the original adapter that cannot be repaired or is too late to repair, you can use another adapter to replace it, as long as the output voltage and power are roughly equivalent. The 24V power adapter manufacturer tells you that there is a voltage regulator circuit inside the notebook, so don’t worry too much about the output voltage mismatch. When repairing, the first step is to prepare tools. We need a multimeter, a screwdriver, and welding tools.

Second, there are four plastic caps on the power adapter. Do not damage the adapter shell as much as possible. After the shell is damaged, problems such as enhanced electromagnetic radiation will occur, which will affect the stability of the machine. The 24V power adapter manufacturer tells you that if the shell is damaged, try to repair it. If the external power supply does not supply power during the disassembly process, you can try plugging in the battery at this time. If the machine can start normally, there may be a problem with the power cord or adapter. After opening the appearance and opening the shielding layer, it is best to check the solder feet first, and observe with the naked eye. The circuit is intermittent, usually due to poor contact. Then check with a multimeter to find out if there is a problem with the power cord to simplify maintenance.
Third, during the test, if the resistance pin is found to be soldered, then use a welding tool to repair it, install the power adapter again, start the test, and the problem is solved. It should be noted that if you encounter a problem with a certain capacitor during the inspection process, you can buy a capacitor with the same model and capacity (the price is about 5 yuan), and then solder the problematic capacitor and solder the new capacitor on. That's it. The 24V power adapter manufacturer tells you that if you find a problem with the IC power chip, you can follow the same method to solve it. Of course, since the IC chip is definitely one of the most important electronic components in the power adapter, the capacitance is too complicated.
Fourth, during the maintenance process of the optional power adapter, the 24V power adapter manufacturer tells you that since the current power adapter has adopted a large number of SMD components, once the component has a problem, the maintenance will be more difficult. The power of the power adapter is also increasing day by day, so that the test of electronic components is getting greater and greater. If the quality of the electronic components used in the power adapter is not good enough, and the PCB wiring is improper, it is likely to increase the probability of failure. Therefore, choosing a good quality power adapter is very helpful to the stability of the notebook.
Fifth, the 24V power adapter manufacturer tells you to check whether there is any problem with the capacitor, resistance, or inductance. If the capacitor is bulging, it is best to replace it in time to avoid hidden dangers.
The above are the five major steps that the 24V power adapter manufacturer tells you to repair the power adapter. Through these five major steps, we can check the power adapter well. Of course, if there is no major problem, it is best not to open the shell easily. If necessary, it is recommended to find a professional to provide better protection.
