    How to keep and maintain Lenovo 19V 4.74A notebook power adapters?

    1. Do not crush, bend the power adapter cable and prevent external insulation sleeve breaking down or poor contact.

    2. Try to avoid using the ac adapters outdoor or in harsh environments, trying to prevent dropping, shocking or getting wet.

    3. When your PC is off, turn off the power adapter from the socket by unplugging the power supply. Because when the power adapter has been in a state of working for a long time, it will affect the adapter’s final life.

    4. The adapter is broadband working voltage, marked from 100 V – 240 V, but if the voltage is unstable, it may cause damage to the power adapter.

    5. Please do not mix the transformer and the power supply, there are some differences between the operating voltage and charging voltage for each electronic product, if used by error, it might damage or even burn the machine.
