1. Create a good cooling environment: When using the notebook in a high temperature environment, the power adapter should be placed in a ventilated place away from direct sunlight; Do not place the power adapter near the cooling air outlet of the notebook, otherwise not only the heat of the power adapter cannot be dissipated, but also absorbs some heat.
2. In case of any abnormality, the power adapter should be stopped in time: when the power adapter emits a loud working noise or even smoke, it is often damaged or has a fault, so it should be stopped immediately, and can be put into use again after being overhauled by a professional engineer.
3. Be careful when using a non original power supply: there may be some differences in the output interface, voltage and current values of the non original power adapter. If it is not matched properly, it may affect the stability of the notebook operation, or even more serious consequences. In addition, the power adapters of notebooks of the same brand and different models should also be changed carefully.
