battery of the same type. To avoid possible injury or death, Do not: (1) throw or immerse into water,
(2) allow it to heat to more than 100°C (212°F), or (3) attempt to repair or disassemble it. Dispose of
it as required by local ordinances or regulations and your company's safety standards.
Connecting to the network
Your computer has one or more network adapters for connecting to the Internet and to your company's
wired LAN or wireless LAN network.
Note: Some ThinkPad notebook computers come with a built-in wireless WAN card enabling you to
establish wireless connections over remote public or private networks.
Ethernet connections
You can connect to your local network or a broadband connection by use of the Ethernet feature built into
your computer. If you are using the Windows 7 operating system, the Access Connections program also
enables you to manage your location proles. For more information, see “Accessing Lenovo programs
on the Windows 7 operating system” on page 15

the telephone cable to the Ethernet connector.
Wireless connections
Wireless communication is the transfer of data without the use of cables but by means of radio waves only.
Depending on the wireless device used in your computer, you might be able to connect to the following
categories of wireless networks.
Wireless LAN
A wireless local area network (LAN) covers a relatively small geographic area, such as an ofce building or a
house. Devices based on the 802.11 standards can connect to this network.
Your computer comes with a built-in wireless network card and a conguration utility to help you make
wireless connections and monitor the status of your connection, so that you can stay connected to your
network while you are in the ofce, in a meeting room, or at home, with no need for a wired connection.
Tips for using the wireless LAN feature
To achieve the best connection, use the following guidelines:
• Place your computer so that there are as few obstacles as possible between the wireless LAN access
point and the computer.
• Open your computer display to an angle of slightly more than 90 degrees.
• If you use the wireless feature (the 802.11 standard) of your computer simultaneously with a Bluetooth
option, the data transmission speed can be delayed and the performance of the wireless feature can be
degraded.
