„ 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.
Do not share an electrical outlet with other home or commercial appliances that draw
large amounts of electricity; otherwise, unstable voltage might damage your computer,
data, or attached devices.
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 attempt to circumvent this
safety feature by trying to insert the plug 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% 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.
Be sure that the power outlet provides the correct voltage and current for the product
you are installing.
Carefully connect and disconnect the equipment from the electrical outlet.
„ External devices
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.
„ Batteries
All personal computers manufactured by Lenovo contain a non-rechargeable 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. Do not put it in fire or hot oven. Do not leave it in an extremely high temperature
surrounding environment that can result in an explosion or the leakage of flammable
