Use the adapter only with laptops that explicitly accept 19V at 2.37A and whose connector is compatible. Avoid exposing the adapter to moisture, extreme temperatures or prolonged direct sunlight. Allow adequate ventilation around the adapter during use and do not cover it with soft materials. If the adapter becomes hot to the touch, produces unusual noise or emits a burning smell, disconnect it immediately and have it inspected or replaced.
