Tips: How to Use Desktop Adapter Correctly?
1. The power adapters of different models of notebooks cannot be mixed.
The power adapters of different brands of notebooks have some differences in output interfaces, voltage and current values, so they cannot be mixed. Otherwise, the battery will not be fully charged, the screen will flicker, etc., or the laptop motherboard or other hardware will be burned. The power adapters of the same brand and different models of notebooks should also be used with caution. It is recommended to consult professional and technical personnel before operating.
2. Reasonably charge the power adapter.
When the laptop battery is in a charging state, it is best not to run large 3D games and other programs that make the whole machine work harder, lest the battery charging speed slows down or the battery is not fully charged due to insufficient output power of the power adapter, and the power supply. The adapter is overloaded, etc.
3. If the power adapter is abnormal, stop using it in time.
When the power adapter emits a lot of working noise or even smoke, it is often damaged or malfunctions. It should be stopped immediately and can be used again after inspection and repair by professional engineers.
