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
Customer Support Center. Use only a 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. Lenovo 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 Customer 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.
© Lenovo 2005, 2007. Portions © IBM Corp. 2005. vii
Do not use any power adapter that shows corrosion at the ac/dc 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.
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
Heat and product ventilation
Computers, combo power adapters, and many accessories can generate heat
when turned on and when batteries are charging. Always follow these basic
precautions:
v Do not leave your computer, combo power adapter, or accessories in contact
with your lap or any part of your body for an extended period when the
products are functioning or when the battery is charging. Your computer,
combo power adapter, and many accessories produce some heat during
normal operation. Extended contact with the body could cause discomfort
or, potentially, a skin burn.
v Do not charge the battery or operate your computer, combo power adapter,
or accessories near flammable materials or in explosive environments.
viii ThinkPad and Lenovo 90W Slim AC/DC Combo Adapter: User’s Guide
v The adapter will produce a lot of heat during operation. Be sure to expose
the adapter to air. Do not place the adapter in the vehicle glove
compartment. Do not cover the adapter with anything that would prevent
heat from dissipating.
v Attention:
Do not use this adapter with a lighter plug splitter or extender cables. These
devices can cause the DC/DC input cable to become very hot.
v Place the power adapter out of reach of children.
Power supply statement
Never remove the cover on a power supply or any part that has the following
label attached.
Verwijder nooit de klep van een voedingseenheid of een ander onderdeel
waarop het volgende etiket is geplakt.

Installation and user’s guide
The ThinkPad and Lenovo 90W Slim AC/DC Combo Adapter powers your
notebook computer using a standard ac power cord, a standard automobile
power receptacle, or a 4-pin in-flight power receptacle. It also charges your
notebook computer battery.
The combo power adapter is designed to use either the AC Input or DC Input
separately, but not at the same time.
Product description
This package includes:
v One ThinkPad and Lenovo 90W Slim AC/DC Combo Adapter (P/N
41R0139)
v One DC/DC input power cord (P/N 41R0144)
v One automobile cigarette lighter adapter
v One standard ac power cord
v Two interchangeable voltage tips (20V Output: P/N 41R4286 and 16V
Output: P/N 41R4285)
v Safety Information
v User’s Guide
v Carrying case for your adapter kit
The adapter has a cable extending from one end of the adapter that connects to
your notebook computer. The adapter has two connectors for the different
electrical source cables.
Using the adapter
The power adapter can be connected to an automobile power receptacle, a
4-pin in-flight power receptacle, or a standard AC electrical socket. During
operation, if the power adapter detects a fault, such as a short circuit or high
temperature, the power adapter will shut down automatically to prevent
damage.
Notes:
1. When the adapter shuts down due to a fault it will be latched off until the
fault is removed AND the adapter is disconnected from the power source
for at least 10 seconds.
2. The adapter needs adequate ventilation for proper operation. It is normal
for the adapter to be warm to touch during use.
© Lenovo 2005, 2007. Portions © IBM Corp. 2005. 1
Connecting the adapter to an automobile power receptacle
To use the power adapter with an automobile power receptacle, complete these
steps:
1. Plug the smaller end of the DC power cord (see1 in the illustration
below).
2. Insert the large end of the cord into the automobile power receptacle (see
2in the illustration below.) The cord is fully inserted when a click is
heard.
3. Insert the smaller, yellow-tipped connector into the power connector of
your notebook computer (see3 in the illustration below). Make sure the
notebook computer is charging by checking the power icon on the system
tray on the computer display. The icon displays as a plug if the computer is
charging or as a battery if it is not.
Note: The adapter is not supported for use in vehicles with 24-volt electrical
systems.
Connecting the adapter to an in-flight power system
To use the power adapter with a 4-pin in-flight power receptacle, follow these
steps:
1. Remove the automobile power receptacle adapter from the large end of the
power cable to reveal the 4-pin airline connector, as shown below.
2 ThinkPad and Lenovo 90W Slim AC/DC Combo Adapter: User’s Guide
2. Plug the smaller end of the DC power cord here (see the illustration
below).
3. Insert the large end of the cord into the in-flight power connector (see 3in
the illustration below.) The cord is fully inserted when a click is heard.
4. Insert the smaller, yellow-tipped connector into the power connector of
your notebook computer (see4 in the illustration below). Make sure the
notebook computer is charging by checking the power icon on the system
tray on the computer display. The icon displays as a plug if the computer is
charging or as a battery if it is not.
