v Only use battery packs and charging devices that have been approved by
IBM for use with your particular product.
v Follow instructions included with your product when charging and
operating the battery.
v Do not open or service your battery. Contact the IBM Support Center for
assistance.
v Do not crush, puncture, or incinerate the battery pack or short circuit the
battery contacts.
v Do not expose the battery to liquids.
v Keep the areas around battery compartments, electrical connectors, and
device bays clean and free of debris, particularly stray metal.
If your battery is damaged, or if you notice a discharge from your battery
v
or the buildup of foreign materials on the battery leads, stop using the
battery, obtain an approved replacement, and properly discard the original
battery.
v The rechargeable battery in your portable personal computer will provide
better performance and longer life if you cycle the battery periodically.
Cycling involves running the laptop on battery mode until the low power
alarm on your battery sounds, then promptly recharging the battery to
100%. You should not allow your battery to remain fully discharged for a
long period of time (referred to as a "deep discharge").
v Batteries may experience a deep discharge if they are left unused for a long
period of time. This may shorten battery life and increase the risk of a short
circuit. Charge batteries periodically, including spare batteries, to avoid
potential problems. Recharging batteries to 40% of their capacity at least
once every six months is advisable.
v If your battery will not charge, will not operate very long in battery mode,
or if the Battery Health indicator is red (this feature may not be included on
your model) you should discontinue using it and obtain an IBM
replacement battery. While you may notice a decrease in performance when
operating without the battery pack, you may continue to operate the
computer using only your AC adapter until you receive your replacement
battery. If the replacement battery does not offer improved performance,
contact the IBM Support Center for assistance.
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.
