DANGER
There is a danger of an explosion if the backup battery is incorrectly placed. The lithium battery
contains lithium and can explode if it is not properly handled, or disposed of. Replace only with a
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 cards for connecting to the Internet and to your company's wired
LAN or wireless LAN network.
The Access Connections program is a connectivity assistant program for creating and managing location
profiles. Each location profile stores all the network and Internet configuration settings needed for connecting
to a network infrastructure from a specific location such as a home or an office.
Ethernet connections
You can connect to your network or a broadband connection, such as DSL or CATV, by use of the Ethernet
feature built into your computer. This feature enables you to do 1Gbps half or full duplex data transmission.
If your are using the Windows 7 operating system, the Access Connections program also enables you to
manage your location profiles. For instructions on how to start the Access Connections program, see
"Accessing Lenovo programs on the Windows 7 operating system" on page 16.
For more information, see the help information system of the program.
DANGER
Your computer has an Ethernet connector. To avoid the risk of electrical shock, do not connect
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 office 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 configuration 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 office, in a meeting room, or at home, with no need for a wired connection.
