Preparation guide

  1. Check the adapter label privately. The guide lists 45 W or 65 W depending on configuration; confirm the supplied or Lenovo-qualified adapter for this unit.

  2. Disconnect the dock and connect the safe adapter to the marked USB-C power connector. Keep the other accessories and workload constant for this direct baseline.

  3. Open Windows Settings → System for battery status and use installed Lenovo Vantage for more detail. Record AC recognition separately from charging progress.

  4. If a second known-compatible Lenovo-qualified adapter is available, compare it on the same outlet and connector. A missing spare stays Not tested; do not measure live contacts or open the adapter.

  5. If external power is recognized but charging pauses, retain the displayed battery state and workload. The manual describes charge-management behavior; one pause cannot locate battery damage.
