Replace notebook power adapter precautions.
A friend who knows the computer knows that the quality of the power supply will also affect the performance of the computer. If the power adapter is used for a long time, it will inevitably have problems. At this time, we should consider changing a new power supply, then when replacing the power adapter. What problems do we need to pay attention to?
The first step is to look at the parameters between the power adapter and the computer. The output voltage of the adapter is the same as the voltage of the laptop. For example, if the output voltage of a notebook computer is 16V, then the output voltage of the power adapter cannot exceed 16V, which can only be equal to or less than. If the voltage is exceeded, the voltage difference between the two is large, which may cause damage to the notebook.
The second step is to select the plug or jack of the adapter to be the same as the laptop. Be careful not to reverse it. For example, if the notebook is marked with internal and external negative, then you need to watch carefully when purchasing the power adapter. As long as the polarity of both is the same, it can be used.
The third step is that the rated output current of the power adapter you choose cannot be lower than the output current of the notebook. For example, the current output of the notebook is 3.36A. The current output of the power adapter you need to purchase cannot be lower than this number. It can only be a power adapter equal to or greater than 3.36A.
