How to use laptop charger correctly?

To use a laptop charger correctly, connect the charger to the wall outlet first, then plug the cable into your laptop. Avoid keeping it plugged in at full charge for extended periods and unplug it once the battery is full to help extend its lifespan. Always use the original charger or one with the same voltage and current specifications for your laptop.

Before you charge

· Use the right charger: Use the original charger that came with your laptop or an identical replacement that matches the voltage and amperage (A) specifications.

· Check connections: Make sure the AC adapter and cable are securely connected and there are no signs of damage.

· Find a safe place: Charge on a hard, flat surface to ensure proper ventilation and avoid overheating.

During the charging process

· Connect to power first: Plug the AC adapter into the wall outlet first, then plug the cable into your laptop. This can help prevent a power surge from damaging the laptop.

· Unplug when full: Once your laptop is fully charged, unplug the charger. This is especially important for older batteries and helps prevent overcharging, which can degrade the battery over time.

· Follow the 20/80 rule: For optimal battery health, some experts suggest plugging in the charger when the battery is around 20% and unplugging it when it reaches 80%.

What to avoid

· Avoid physical damage: Don't wrap the cords too tightly or bend them sharply, as this can cause damage over time.

· Don't use damaged equipment: If the charger or cable is frayed or damaged, replace it immediately to avoid fire hazards or damage to your laptop.

· Don't leave it plugged in 24/7: While modern laptops have built-in protections against overcharging, keeping the battery constantly at 100% can still reduce its overall lifespan.
