Operating Instructions
- Initiating Charge: Once all connections are secure and the charger is plugged into a live outlet, the charger will automatically begin supplying power to your laptop. A small blue LED indicator on the charger unit will illuminate to confirm it is active and functioning.

- Automatic Shutdown: The charger is designed to automatically cease charging when your laptop's battery reaches full capacity, preventing overcharging and extending battery life.
Maintenance
- Cleaning: Keep the charger unit and all cables clean and free from dust. Use a soft, dry cloth for cleaning. Do not use liquid cleaners or abrasive materials.
- Environmental Conditions: Avoid exposing the charger to moisture, direct sunlight, or extreme temperatures (both hot and cold).
- Cable Care: Do not bend, twist, or crimp the cables excessively. Always grasp the plug when disconnecting from the wall outlet or laptop, rather than pulling on the cable itself, to prevent internal wire damage.
- Storage: When not in use, store the charger in a cool, dry place, away from children and pets.
Troubleshooting
- Charger not powering on or laptop not charging:
- Ensure all connections are secure: the power cable to the charger, the charger to the wall outlet, and the tip to the laptop.
- Verify the wall outlet is functional by plugging in another device.
- Check if the correct tip is securely attached to the charger and properly inserted into the laptop's charging port.
- If the issue persists, disconnect all components, wait a few minutes, and then reconnect them.
- LED indicator not lit:
- Follow the steps above for 'Charger not powering on or laptop not charging'.
- A non-lit LED typically indicates no power input or a connection issue.
