OEM Toshiba Laptop Adapter 15V3A 6.3*3.0mm DC Tip

• The role of the power adapter is the transformer and rectifier. The household alternating current is 220v, and our computer uses 12v DC (as if it is), so it is certain that the power adapter is a transformer and rectifier. The transformer is made of silicon steel sheet. After the transformer is energized, it generates magnetic flux. The magnetic flux will cause a forceful effect between the silicon steel sheets, which will produce a humming sound. This is normal. Then the adapter is a transformer. We should all know that AC 220v is transformed by a transformer and DC by a rectifier. There is consumption here, and these consumption will be converted into heat, so it is normal for the power adapter to generate heat. But the sound of overheating ground is abnormal, and there are many reasons: 1. The AC voltage is unstable. 2. The chip is damaged. 3. Short circuit between turns. 4. The component is damaged.
