how to install Lenovo AC Adapter

• Step 1 — Inspect and prepare: Before connecting anything, inspect the adapter, power cord, and connector for any signs of damage. If you notice frayed cables or bent tips, do not use the unit. Ensure you have the correct regional power cord if a detachable cord is included, and align the connector tip to the appropriate Lenovo charging port on your device.
• Step 2 — Connect to power: Plug the included power cord into a properly grounded wall outlet. If you’re traveling internationally, use a compatible regional power cord or adapter that supports 100-240 V AC, and ensure it is rated for the local outlet type. This step establishes the supply that your Lenovo charger will regulate and deliver to your laptop.
• Step 3 — Attach to your device: With the adapter powered, gently insert the Lenovo-compatible tip into the laptop’s charging port. Make sure the connection is snug and fully seated to ensure stable voltage delivery. Avoid forcing the connector or using excessive force, as a secure fit helps prevent intermittent charging and potential wear on the port.
• Step 4 — Verify charging: Once connected, your Lenovo device should begin charging. Look for any charging indicators on your laptop screen or status LEDs on the adapter (if present) to confirm the connection is active. If charging does not begin, re-seat the tip or try a different compatible tip if your kit includes multiple connectors. If issues persist, remove the plug, wait a moment, and reinsert to reset the connection.
• Step 5 — Safety and storage: When not in use, unplug the adapter from the wall outlet and disconnect it from your device. Store the charger in a cool, dry place away from direct heat and moisture. If you travel with it, keep the cabling neatly coiled to avoid wear and ensure quick access when you need it again.
