Check three possible causes: a faulty charger, unsuitable ambient temperature, or a poor connection. Contact a Lenovo authorized service center or dealer for a charger issue.
Only use the supplied charger, charge the battery in a cool, ventilated place, and never expose it to high temperature, moisture, or physical damage.
Only accessories approved by Lenovo may be used; using third‑party parts can void the warranty and cause damage.
Replace the battery with a new one that meets the specifications; do not attempt to repair or reuse a damaged battery.
