It is well known that if electronic equipment fails, it can be disassembled and repaired. However, if the power supply is damaged or some components are damaged, it cannot be repaired at all. The power supply can not be disassembled, especially the power supply in notebook computer, which is under great pressure. If it is broken, it cannot be repaired at all, so people must be aware of this problem. The power adapter can only be used when it is protected. Therefore, people must know how to protect the power supply so that it will not fall down for a long time.
Many electronic devices have high requirements for power supply. If it is not the same batch and the same model of power supply, it can not be used reasonably at all, because the voltage and current of each electronic device are different. We must know how to control the influence of current and voltage on electronic equipment. The power adapter can better adjust the voltage and current, but if it is immersed in water or stored in a humid environment for a long time, many parts will be damp and dangerous when powered on, which is also a noteworthy place.
All electronic equipment shall be handled with care. The same is true when using power in daily life. If you always fall and touch, the parts inside will fall off. Many electronic devices can only use one set of power adapters. Only care and protection during use can ensure the rational use of power supply, especially some electronic equipment that has been delivered for many years. However, if the power supply equipment is damaged, the electronic equipment cannot be equipped with the original power supply at all. In this case, the electronic equipment is scrapped, so we must pay attention to protecting the power supply.
