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.
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.
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.
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
