Do not bend or modify the plug. If the plug is damaged, contact the manufacturer to obtain a
replacement.
Some products are equipped with a three-pronged plug. This plug fits only into a grounded electrical
outlet. This is a safety feature. Do not defeat this safety feature by trying to insert it into a non-grounded
outlet. If you cannot insert the plug into the outlet, contact an electrician for an approved outlet adapter
or to replace the outlet with one that enables this safety feature. Never overload an electrical outlet. The
overall system load should not exceed 80 percent of the branch circuit rating. Consult an electrician for
more information if you have questions about power loads and branch circuit ratings.
Be sure that the power outlet you are using is properly wired, easily accessible, and located close to the
equipment. Do not fully extend power cords in a way that will stress the cords.
Connect and disconnect the equipment from the electrical outlet carefully

Batteries

All IBM personal computers contain a non-rechargeable coin cell battery to provide power to the system
clock. In addition many mobile products such as Thinkpad notebook PCs utilize a rechargeable battery
pack to provide system power when in portable mode. Batteries supplied by IBM for use with your
product have been tested for compatibility and should only be replaced with IBM 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 to instructions included in the product documentation.
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 battery or the 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 discharged state could increase the risk
of a battery short 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.

Heat and product ventilation

Computers generate heat when turned on and when batteries are charging. Notebook PCs can generate a
significant amount of heat due to their compact size. Always follow these basic precautions:
v Do not leave the base of your computer in contact with your lap or any part of your body for an
extended period when the computer is functioning or when the battery is charging. Your computer
produces some heat during normal operation. Extended contact with the body could cause discomfort
or, potentially, a skin burn.
v Do not operate your computer or charge the battery near flammable materials or in explosive
environments.
v Ventilation slots, fans and/or heat sinks are provided with the product for safety, comfort, and 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.
