Chapter 1. Important safety information
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
tibility 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 batt
ery 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 di
scharged 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.
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
nger of an
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.
