General safety guidelines
Always observe the following precautions to reduce the risk of injury and property damage.
Service
Do not attempt to service a product yourself unless instructed to do so by the IBM Support
Center. Use only an IBM authorized service provider who is approved to repair your
particular product.
Note: Some parts can be upgraded or replaced by the customer. These parts are referred
to as Customer Replaceable Units, or CRUs. IBM expressly identifies CRUs as such, and
provides documentation with instructions when it is appropriate for customers to replace
those parts. You must closely follow all instructions when performing such replacements.
Always make sure that the power is turned off and that the product is unplugged from
any power source before you attempt the replacement. If you have any questions or
concerns, contact the IBM Support Center.
Power cords and power adapters
Use only the power cords and power adapters supplied by the product manufacturer.
Never wrap a power cord around the power adapter or other object. Doing so can stress
the cord in ways that can cause the cord to fray, crack or crimp. This can present a
safety hazard.
Always route power cords so that they will not be walked on, tripped over, or pinched
by objects.
Protect the cord and power adapters from liquids. For instance, do not leave your 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 cord or power adapter has been stressed
by misuse. Liquids can also cause gradual corrosion of the power cord terminals and/or
the connector terminals on the 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 corrosion at the ac input pins and/or shows
signs of overheating (such as deformed plastic) at the ac input or anywhere on the power
adapter.
Do not use any power cords where the electrical contacts on either end show signs of
corrosion or overheating or where the power cord appears to have been damaged in any
way.
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.
Plugs and outlets
If a receptacle (power outlet) that you intend to use with your computer equipment appears
to be damaged or corroded, do not use the outlet until it is replaced by a qualified
electrician.
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.
Batteries
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
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.
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 machine, do the following:
v Always store CD/DVD discs in their original packaging
v Always store CD/DVD discs out of direct sunlight and away from direct heat sources
v Remove CD/DVD discs from the computer when not in use
v Do not bend or flex CD/DVD discs, or force them into the computer or their packaging
v Check CD/DVD discs for cracks before each use. Do not use cracked or damaged discs
