1. Be careful not to insert the power cord port into other ports, insert and pull out the wiring horizontally to prevent the port from loosening. Do not plug or unplug serial ports, parallel ports, PS/2 and other interfaces when powered on.
2. Check the capacitor, resistance and inductance for any problems. If the capacitor is bulging, it is best to replace it in time to avoid hidden dangers. Pay attention to the power cord, and try to pay attention when winding the notebook power cord to avoid breaking the internal cable and causing a circuit break. If the external power supply does not supply power, you can plug in the laptop battery and try. If the laptop can start normally, there may be a problem with the laptop power cord or laptop power adapter. Then check with a multimeter to find out whether there is a problem with the notebook power cord to simplify the difficulty of troubleshooting. Don't try to open the notebook power adapter shell at the beginning.
3. Anti-potent chemicals. Do not use harsh chemicals, cleaning agents or strong detergents to clean the charger. To remove the external stains on the charger, use cotton dipped in a little absolute alcohol to scrub.
4, waterproof and moisture-proof. As an electronic product, accidental ingress of water or exposure to humid air when it is not used for a long time will cause different degrees of corrosion or oxidation to its internal electronic components.
5. Anti-fall and anti-vibration. The mobile phone charger is actually a fragile component, and the internal components cannot withstand beatings.
6. Discharge static electricity when cleaning. Clean the charger and charging port regularly. When cleaning, use a damp cloth or an antistatic cloth. Do not use a dry cloth! Accidentally fall to the ground during use. Do not throw, knock or shake the charger.
7. Anti-cold and anti-heat. Do not place the charger in a place where the temperature is too high. High temperature will shorten the life of electronic devices, destroy the charger, and deform or melt some plastic parts. Do not store the charger in a cold place. When the charger is working in a very cold environment, when the internal temperature rises, moisture will form in the charger and damage the circuit board.
