There are more and more varieties of power adapters, but the points of use are similar. In the entire notebook computer system, the input of the power adapter is 220V. The current notebook computer configuration is getting higher and higher, and the power consumption is also increasing, especially the high frequency P4-M equipment is even more power consumption. If the voltage and current of the power adapter are not enough, it is very easy to cause the screen to flicker. Hard disk failure. The battery can't be fully charged and the machine freezes for no reason. If the battery is taken out and directly plugged into the power source, 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 becomes hotter than usual, which will adversely affect the service life of the laptop.

For the convenience of carrying, the power adapter of the notebook computer has a compact internal structure. Although it is not as fragile as a battery, it should also be free from impacts and drops. Many people attach great importance to the heat dissipation of notebook computers, but very few people care about power adapters. In fact, the heat generated by the power adapter of many devices is by no means inferior to that of a notebook. When using it, be careful not to cover it with clothes and newspapers, and place it in a place with good air circulation to prevent partial melting of the surface due to the inability to release heat.

In addition, the wire between the power adapter and the laptop is relatively thin and easy to bend. Many consumers don’t care and wind it at various angles to facilitate carrying. In fact, it is very easy to cause the internal copper wire to open or short, especially in It is especially easy to happen when the outer skin of the wire becomes fragile in cold weather. In order to prevent such accidents, the wire should be wound as loosely as possible, and wound around the two ends instead of the middle part of the power adapter as much as possible.
