The notebook computer is a highly integrated electrical equipment, which has high requirements for voltage and current. At the same time, its internal electronic components are relatively fragile. If the input current or voltage is not within the design range of the relevant circuit, it may cause serious consequences of burning the chip or other electronic components, so the power adapter and battery of the notebook computer power supply equipment are stable. Sex becomes very important.
There are many faults related to the power supply of notebook computers. On the one hand, they are caused by problems with related circuits such as the protection isolation circuit and charging control circuit in the notebook computer host; on the other hand, they are caused by problems with the power adapter and the battery itself.
Common faults of the power adapter mainly include no voltage output or unstable output voltage. The input voltage of the notebook computer power adapter is usually AC 100V～240V. If the power adapter's access voltage is not in this range, it is likely to cause the power adapter to burn down. The power adapter itself generates a large amount of heat. If the heat dissipation conditions are not good during use, the internal circuit may not work normally, resulting in a failure of no voltage output or unstable voltage output.
The faults caused by the laptop battery's own problems mainly include the battery has no voltage output and cannot be charged. The charging and discharging of the battery cells of a laptop computer have certain limits, and damage may occur if the limits are exceeded. The circuit board in the battery has a certain protective effect on charging and discharging, but it may also malfunction, causing the battery to have no voltage output or fail to charge.
