Chapter 1. Important safety information

Protect power cords and power adapters from liquids. For instance, do not leave your power cord or power adapter near sinks, tubs, toilets, or on floors that are cleaned with liquid cleansers. Liquids can cause a short circuit, particularly if the power cord or power adapter has been stressed by misuse. Liquids also can cause grad connector terminals on a power adapter, which can eventually result in overheating.

Always connect power cords and signal cables in the correct order and ensure that all power cord connectors are securely and completely plugged into receptacles.

Do not use any power adapter that shows corrosio shows signs of overheating (such as deformed plastic) at the ac input or anywhere on the power adapter.

 Batteries

Personal computers manufactured by Lenovo contain a coin cell battery to provide power to the system clock. In addition, many mobile products, such as notebook computers, utilize a rechargeable battery pack to provide system power when in portable mode. Batteries supplied by Lenovo for use with your product have been tested for compa with approved parts.

Never attempt to open or service any battery. Do not crush, puncture, or incinerate batteries or short circuit the metal contacts. Do not expose the battery to water or other liquids. Only recharge the battery pack strictly according

Battery abuse or mishandling can cause the battery to overheat, which can cause gasses or flame to “vent” from the battery pack or coin cell. If your battery is damaged, or if you notice any discharge from your batt buildup of foreign materials on the battery leads, stop using the battery and obtain a replacement from the battery manufacturer.

Batteries can degrade when they are left unused for long periods of time. For some rechargeable batteries (particularly Lithium Ion batteries), leaving a battery unused in a di circuit, which could shorten the life of the battery and can also pose a safety hazard. Do not let rechargeable Lithium-Ion batteries completely discharge or store these batteries in a discharged state.

 Rechargeable battery notice

Do not attempt to disassemble or modify the battery pack. Attempting to do so can cause an explosion, or liquid leakage from the battery pack. A battery pack other than the one specified by Lenovo, or a disassembled or modified battery pack is not covered by the warranty.

If the rechargeable battery pack is incorrectly replaced, there is da explosion. The battery pack contains a small amount of harmful substances. To avoid possible injury:

• Replace only with a battery of the type recommended by Lenovo.

• Keep the battery pack away from fire.

• Do not expose it to water or rain.

• Do not attempt to disassemble it.

• Do not short-circuit it.

• Keep it away from children.

• Do not drop the battery pack. Do not put the battery pack in trash that is disposed of in landfills. When disposing of the battery, comply with local ordinances or regulations.

If the battery pack is to be stored separately, place it in a dry environment of a temperature between 10-35 °C and keep it away from direct sunlight. To extend battery life, we recommend you charge the battery to approximately 30 to 50% capacity and recharge it every three months to prevent the battery from over-discharging.

This sy

stem does not support batteries that are not genuine Lenovo-made or authorized. The system will continue to boot, but may not charge unauthorized batteries.

 Heat and product ventilation

Computers, AC adapters, and many accessories can generate heat when turned on and when batteries are charging. Notebook computers can generate a significant amount of heat due to their compact size. Always

follow these basic precautions:

• When your computer is turned on or the battery

is charging, the base, the palm rest, and some other parts may become hot. Avoid keeping your hands, your lap, or any other part of your body in contact with a hot section of the computer for any extended length of time. When you use the keyboard, avoid keeping your palms on the palm rest for a prolonged period of time. Your computer ge

nerates some heat during normal operation. The amount of heat depends on the amount of system activity and the battery charge level. Extended contact with your body, even

through clothing, could cause discomfort or even a skin burn. Periodically take breaks from using the keyboard by lifting you

r hands from the palm rest; and be careful not to use the keyboard for any extended length of time.

• Do not operate your computer or charge the battery near flammable materials or in explosive environments.

• Ventilation slots, fans and/or heat sinks are provided with the product for safety, comf o r t, an

d reliable operation. These features might inadvertently become blocked by placing the product on a bed, sofa, carpet, or other flexible surface. Never block, cover, or disable these features.

Chapter 1. Important safety information

• When the AC adapter is connected to an electrical outlet and your computer, it generates heat. Do not place the adapter in contact with any part of your body while using it. Never use the AC adapter to warm your body. Extended contact with your body, even

through clothing, may cause

a skin burn.

For your safety, always follow these basic precautions with your computer:

• Keep the cover closed whenever the computer is plugged in.

• Regularly inspect the outside of the computer for dust accumulation.

• Remove dust from vents and any perforations in the bezel. More freque cleanings might be required for computers in dusty or high-traffic areas.

• Do not restrict or block any ventilation openings.

• Do not operate your computer inside furniture, as this might increase the risk of overheating.

• Airflow temperatures into the computer should not exceed 35°C (

95°F).

 CD and DVD drive safety

CD and DVD drives spin discs at a high speed. If a CD or DVD is cracked or otherwise physically damaged, it is possible for the disc to break apart or even shatter when the CD drive is in use. To protect against possible injury due to this situation, and to reduce the risk of damage to your comput the following:

• Always store CD/DVD discs in their original packaging.

• Always store CD/DVD discs out of direct sunlight and away from direct heat sources.

• Remove CD/DVD discs from the computer when not in use.

• Do not bend or flex CD/DVD discs, or force them into the computer or their packaging.

• Check CD/DVD discs for cracks before each use. Do not use cracked or damag

ed discs.
