Since the inside of the 65W laptop power adapter is a switching power supply working at high voltage and high current, the workload is relatively heavy, and it is a fully enclosed structure. There are no cooling holes on the outer shell and no fan inside to assist heat dissipation. The internal temperature is very high when working. Especially in the hot summer, you can feel hot when you touch the surface with your hands, and the internal temperature is higher. Therefore, it must be properly maintained and maintained during daily office work and entertainment.

1. Create a good cooling environment. When using a notebook in a high temperature environment, the 65W laptop power adapter should be placed in a place free from direct sunlight and ventilated; do not place the power adapter near the cooling outlet of the notebook, otherwise not only the heat of the power adapter will not be dissipated , but also to absorb part of the heat. In the hot summer, we can put the adapter on its side to increase the contact area between the adapter and the air, so that the heat of the adapter can be dissipated better. In order to obtain a better heat dissipation effect, we can also place a narrow plastic or metal block between the adapter and the desktop to increase the air convection speed around the adapter and accelerate the heat dissipation of the adapter. the
2. In case of abnormality, stop using it in time. When the 65W laptop power adapter emits a large working noise or even emits smoke, it is usually damaged or malfunctioned, and it should be stopped immediately, and it can be put into use again after being overhauled by a professional engineer. the
3. Be cautious when using a non-original power supply. Non-original power adapters may have some differences in the output interface, voltage and current values (or the nominal is not consistent with the actual), if not matched properly, it may affect the stability of the notebook operation, or even more serious consequences. In addition, you should be cautious when switching between 65W laptop power adapters of the same brand and different models, which we will introduce in detail later.
