Where is the importance of the DC-DC adapter reflected?

1.The DC-DC adapter is a device that transforms, rectifies, filters and stabilizes 220-volt AC current to output power suitable for electrical appliances.

2.The function is to provide the voltage, current and stability required by electrical appliances, so that the corresponding electrical appliances can operate safely and stably. Widely used in portable electronic devices and electrical appliances.

3.Without the DC-DC adapter, the electrical appliance cannot function.

How to tell if the DC-DC adapter is good or bad?

1. Check if the DC-DC adapter has voltage output

Set the multimeter to the DC voltage range, connect the computer charger to the mains and measure whether there is voltage on the charging socket.

2.Check that the output voltage of the DC-DC adapter is normal

If the charger has a voltage output, also observe the voltage indicator on the multimeter to see if it matches the rated output voltage specified on the charger.

If you don't have a multimeter, you can only see if the charger is charging correctly.

What is the repair method for the DC-DC adapter?

1.First, we can assess the situation according to the instructions. You can see the indicator light of the DC-DC adapter. When the indicator light is on, it is generally assumed that there is no problem between the power supply and the adapter. Care must be taken not to damage the indicator lamp itself.

2.Check if there is power between the DC-DC adapter and the computer. We can display it via the notebook indicator light, when the notebook is powered, the charging indicator light lights up. Otherwise, it won't glow. Or find a power supply of the same brand and try it out. Use your DC-DC adapter to hold the other party's laptop. If the other party's computer is working normally, your DC-DC adapter is fine. Otherwise, there may be a problem with your power supply. If the other party's DC-DC adapter is connected to your computer and your computer is working normally but your own power adapter is not working normally, then your power adapter is defective.

3. Observe the change of the computer's indicator light. If after connecting the DC-DC adapter, you can see that the charging indicator light is on and off and does not go out for a while, there is a problem with the DC-DC adapter interface in the notebook. In general, the line inside may be broken and the circuit may be broken. PCB aging, solder waste, etc. This is called a virtual welding phenomenon. In this case, as a rule, repair by a specialist is required.
