Presario CQ42-300 Laptop AC Adapter Maintenance Tips

• Each laptop computer requires a unique voltage, current and connector. Make sure your new Presario CQ42-300 computer charger has the same plug (adapter tip) as the original one and outputs the same voltage as the original one.
• Leaving a battery in a laptop while using Presario CQ42-300 adapter for long periods of time will keep the battery in a constant state of charging up and that will reduce the life cycle of the battery.
• Always put first the DC output plug into the laptop’s power jack before putting the input plug on the power outlet. This is the correct method.
• Switch off your compaq laptop ac adapter when you are not using the laptop to prevent overheating.
• Don’t place the Presario CQ42-300 AC Laptop Adapter in a cool place or near the air conditioner to avoid the device from getting moistened.
