How to use

Connect the adapter to a mains outlet using the supplied AC cable or an appropriate mains lead. Plug the DC connector into the laptop’s power input jack firmly until it seats. Ensure the laptop is switched off or in a stable state while connecting for best practice. The adapter will provide power and charge the battery when the laptop’s charging circuitry accepts the input. Disconnect the adapter by removing the DC plug first and then unplugging the mains lead when power is no longer required. Avoid bending the cable sharply near the connector to extend cable life.

Usage recommendations

Use the adapter only with laptops that accept a 19V/2.37A input and the matching DC plug. Inspect the cable and connectors periodically for wear or damage, and avoid exposure to excessive moisture or extreme heat. For travel, use a protective pouch to prevent impact damage. If the laptop does not charge or behaves unexpectedly, verify compatibility and check for loose connections before seeking technical service.
