There are more and more kinds of power adapters, but the use points are similar. In the whole notebook computer system, the input of the power adapter is 220V. At present, the notebook computer configuration is higher and higher, and the power consumption is also larger and larger, especially the P4-M equipment with high dominant frequency. If the voltage and current of the power adapter are not enough, it is very easy to cause the screen flashing, hard disk failure, battery failure, and unexplained crash. If the battery is taken out and directly plugged into the power supply, it is more likely to cause damage. When the current and voltage of the power adapter are not enough, it may cause the line load to increase, and the equipment burns more than usual, which will have an adverse impact on the service life of the notebook computer.
The internal structure of the power adapter of notebook computer is very compact in order to be easy to carry. Although it is not as fragile as the battery, it should also prevent collision and falling. Many people attach great importance to the heat dissipation of notebook computers, but few people care about the power adapter. In fact, the heating capacity of the power adapter of many devices is no less than that of the notebook. In use, pay attention not to cover it with clothes and newspapers, and put it in a place with good air circulation to prevent local melting of the surface due to the inability to release heat.
In addition, the wire between the power adapter and the laptop is thin and easy to bend. Many consumers don’t care and wrap it at various angles to facilitate carrying. In fact, it is very easy to cause open circuit or short circuit of the internal copper wire, especially when the surface of the wire becomes fragile in cold weather. In order to prevent such accidents, the wire should be wound as loose as possible and wrapped at both ends instead of the middle part of the power adapter.
