Dell C540, C640 manual Battery

CAUTION: Safety Instructions (continued)

•Be sure that nothing rests on your AC adapter’s power cable and that the cable is not located where it can be tripped over or stepped on.

•If you are using a multiple-outlet power strip, use caution when plugging the AC adapter’s power cable into the power strip. Some power strips may allow you to insert the plug incorrectly. Incorrect insertion of the power plug could result in permanent damage to your computer, as well as risk of electric shock and/or fire. Ensure that the ground prong of the power plug is inserted into the mating ground contact of the power strip.

Battery

•Use only Dell™ battery modules that are approved for use with this computer. Use of other types may increase the risk of fire or explosion.

•Do not carry a battery pack in your pocket, purse, or other container where metal objects (such as car keys or paper clips) could short-circuit the battery terminals. The resulting excessive current flow can cause extremely high temperatures and may result in damage to the battery pack or cause fire or burns.

•The battery poses a burn hazard if you handle it improperly. Do not disassemble it. Handle a damaged or leaking battery pack with extreme care. If the battery is damaged, electrolyte may leak from the cells and may cause personal injury.

•Keep the battery away from children.

•Do not store or leave your computer or battery pack near a heat source such as a radiator, fireplace, stove, electric heater, or other heat-generating appliance or otherwise expose it to temperatures in excess of 60ºC (140ºF). When heated to excessive temperatures, battery cells could explode or vent, posing a risk of fire.

•Do not dispose of your computer’s battery in a fire or with normal household waste. Battery cells may explode. Discard a used battery according to the manufacturer’s instructions or contact your local waste disposal agency for disposal instructions. Dispose of a spent or damaged battery promptly.
