The DC-DC Adapter provides a wide voltage and current surface and can automatically select the number of power supply levels.
What is the quality test method for DC-DC Adapter?
What is the repair method for the DC-DC Adapter?
Is it normal for the DC-DC Adapter to heat up during use?
During the DC-DC Adapter test process, if it is found that the resistor pins are soldered, then use a welding tool to repair them, install the power adapter, and start the test. The problem is solved. It should be noted that if there is a problem with a certain capacitor during the testing process, you can buy a capacitor with the same model and capacity, then solder the problematic capacitor down and solder the new capacitor on. If there is a problem with the IC power supply chip, it can be solved in the same way. Of course, since the IC chip is definitely one of the most important electronic components in the DC-DC Adapter, the capacitor is too complicated.
First, if there is a problem with the original DC-DC Adapter, it cannot be repaired or it is too late to repair, you can use other adapters instead, as long as the output voltage and power are roughly the same. There is also a voltage stabilizing circuit inside the notebook computer, so don't worry too much about the mismatch of the output voltage. When it comes to maintenance, the first step you need to do is to prepare the tools. We need multimeters, screwdrivers, welding tools.
Second, there are four plastic caps on the DC-DC Adapter. Try not to damage the adapter shell. After the shell is damaged, there will be problems such as strengthening of electromagnetic radiation, which will affect the stability of the machine. If the casing 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 the 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, generally poor contact. Then test with a multimeter to find out if there is a problem with the power cord to simplify maintenance.
The DC-DC Adapter converts alternating current into direct current and adjusts the voltage to a specified voltage and then outputs it to the laptop charging module. The battery charging module will control the connection between the adapter and the battery according to the charging ratio set by the computer. If the battery power ratio is not reached, The battery will be charged, and a certain amount of power consumption will be generated during this process, so heat will be generated, which is a normal situation. If overheating affects the use, it is recommended to go to the service center for inspection.
