Common failures of notebook power adapter

<p>The notebook computer is a highly integrated electrical equipment, which has high requirements on voltage and current. At the same time, the 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 stability of the notebook<a href="https://www.fuyuanpower.com/power-adapter" rel="noopener noreferrer" target="_blank"> <a href="https://www.fuyuanpower.com/power-adapter" target="_blank">power adapter</a> </a>and battery becomes Very important.</p><p>There are many failures related to laptop power supply. On the one hand, it is caused by problems in the protective isolation circuit and charging control circuit in the laptop host. On the other hand, it is caused by problems in the laptop power adapter and the battery itself.</p><p><br></p><p>Common failures of <a href="https://www.fuyuanpower.com/power-adapter" rel="noopener noreferrer" target="_blank">power adapters</a> mainly include no-voltage output or unstable output voltage. The input voltage of the notebook power adapter is usually AC 100V ~ 240V. If the input voltage of the power adapter is not within this range, it is likely to cause the power adapter to burn out.</p><p><br></p><p>The notebook <a href="https://www.fuyuanpower.com/power-adapter" rel="noopener noreferrer" target="_blank">power adapter</a> itself generates a lot of heat. If the heat dissipation conditions are not good during use, the internal circuit may not work properly, resulting in a failure of no-voltage output or unstable voltage output.</p>
