Dell Inspiron 300m - Manual (Page 3)

Before you clean your battery charger, remove power. Clean your battery charger with a soft cloth dampened with water. Do not use liquid or aerosol
cleaners, which may contain flammable substances.
Power
Use only the Dell-provided AC adapter approved for use with this battery charger. Use of another AC adapter may cause a fire or explosion.
Before you connect the battery charger to an electrical outlet, check the AC adapter voltage rating to ensure that the required voltage and frequency match
the available power source.
To remove the battery charger from all power sources, turn the computer off, remove the battery pack, and disconnect the AC adapter from the electrical
outlet.
To help prevent electric shock, plug the AC adapter and peripheral power cables into properly grounded power sources. These power cables may be
equipped with three-prong plugs to provide an earth grounding connection. Do not use adapter plugs or remove the grounding prong from the power cable
plug. If you use a power extension cable, use the appropriate type, two-prong or three-prong, to mate with the AC adapter power cable.
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 your 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.
When Using Your Battery Charger
Observe the following safe-handling guidelines to prevent damage to your battery charger:
l When setting up the battery charger for work, place it on a level surface.
l Protect your battery charger from environmental hazards such as dirt, dust, food, liquids, temperature extremes, and overexposure to sunlight.
l When you move your battery charger between environments with very different temperature and/or humidity ranges, condensation may form on or
within the computer. To avoid damaging the battery charger, allow sufficient time for the moisture to evaporate before using the battery charger.
