NOTICE: When taking the battery charger from low-temperature conditions into a warmer environment or from high-temperature conditions into a cooler environment, allow the battery charger to acclimate to room temperature before turning on power.
•When you disconnect a cable, pull on its connector on its strain-relief loop, not on the cable itself. As you pull out the connector, keep it evenly aligned to avoid bending any connector pins. Also, before you connect a cable make sure both connectors are correctly oriented and aligned
•If your battery charger gets wet or is damaged, follow the procedures described in "Solving Problems." If, after following these procedures, you confirm that your battery charger is not operating properly, contact Dell (see "Getting Help" in your the documentation that came with your computer for the appropriate contact information).
Battery Disposal
Your computer uses a lithium-ion battery and a nickel-metal hydride (NiMH) coin-cell battery. For instructions about replacing the lithium-ion battery in your computer, refer to the section about replacing the battery in your Dell computer documentation. The NiMH battery is a long-life battery, and it is very possible that you will never need to replace it. However, should you need to replace it, the procedure must be performed by an authorized service technician.
Do not dispose of the battery along with household waste. Contact your local waste disposal agency for the address of the nearest battery deposit site.
