Extension cords and related devices

Ensure that extension cords, surge protectors, uninterruptible power supplies, and power strips that you use
are rated to handle the electrical requirements of the product. Never overload these devices. If power strips
are used, the load should not exceed the power strip input rating. Consult an electrician for more information
if you have questions about power loads, power requirements, and input ratings.

Do not connect or disconnect any external device cables other than USB and 1394 cables while the
computer power is on; otherwise, you might damage your computer. To avoid possible damage to
attached devices, wait at least five seconds after the computer is shut down to disconnect external
devices.

General battery notice

DANGER
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 compatibility and should only be replaced
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 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 also can
pose a safety hazard. Do not let rechargeable lithium-ion batteries completely discharge or store
these batteries in a discharged state.
