The laptop power adapter is hot
My point of view: First: your laptop power supply in a small ventilation environment, resulting in poor heat dissipation,
Second: the life of the power supply is 3-5 years, the gradual oxidation of electronic components and some of the aging components, resulting in no load and load a lot of power,
Third: the battery close to each run, and then connected to the power, the power to the battery charger and notebook power supply, so the pressure is not hot strange.
Almost all of the notebook adapters have this problem, you do not have to worry about this. But do not know you can not tolerate what is the degree, if it is so hot that the adapter has a deformation, then it is recommended to immediately stop using, to the sale to the new
Notebook power adapter in the power after the use of hot is a normal phenomenon, do not worry, no danger, it will not explode. The length of this time does not matter, in the use of one or two hours will become very hot, but will always keep this temperature. And the notebook's power adapter shell are high temperature, will not burn.
Notebook power adapter in addition to hot, you may hear the sound, the sound is not, very small. This sound is not a big problem, it is the power adapter power after the power filter sound, so plug in the plug after. Any power adapter basically has a sound. You can listen carefully, the surrounding environment is particularly quiet when you can hear.
Power adapter is a transformer, inside the transformer coil in the AC will produce Zizi sound. Some power adapter use a long time will have this sound, but no big problem, you can continue to use. As long as the sound is not high outrageous do not control.
Laptop power adapter hot and sound basic are considered normal, unless the temperature is too high or even damage to the shell or the sound is very obvious, this is a problem. The general does not affect the use of the adapter bad to buy a can. Notebooks have to protect the isolation circuit, do not worry about damage to the notebook.
