Setting Up Your Computer 25
Setting Up the Docking Device to Connect to a Network
NOTE: A network adapter is also referred to as a network interface controller (NIC).
NOTICE: Do not install a network adapter or a network adapter/modem combination PC Card until you
complete the docking device setup.
NOTICE: To prevent serious operating system problems, do not connect your computer to a docking
device until the Windows operating system setup on the computer is complete.
A docking device allows you to more fully integrate your portable computer into a
desktop environment.
For instructions and details on setting up a docking device, refer to the documentation that came
packaged with the device.
Power Protection Devices
Several devices are available to protect against power fluctuations and failures:
• Surge protectors
• Line conditioners
• Uninterruptible power supplies (UPS)
Surge Protectors
Surge protectors and power strips equipped with surge protection help to prevent damage to your
computer from voltage spikes that can occur during electrical storms or following power interruptions.
The level of protection is usually commensurate with the cost of the surge protector. Some surge
protector manufacturers include warranty coverage for certain types of damage. Carefully read the
device warranty when choosing a surge protector. A device with a higher joule rating offers more
protection. Compare joule ratings to determine the relative effectiveness of different devices.
NOTICE: Most surge protectors do not protect against power fluctuations or power interruptions
caused by nearby lightning strikes. When lightning occurs in your area, disconnect the telephone line
from the telephone wall jack and disconnect your computer from the electrical outlet.
Many surge protectors have a telephone jack for modem protection. See the surge protector
documentation for modem connection instructions.
NOTICE: Not all surge protectors offer network adapter protection. Disconnect the network cable from
the network wall jack during electrical storms.
Line Conditioners
NOTICE: Line conditioners do not protect against power interruptions.
Line conditioners are designed to maintain AC voltage at a fairly constant level.
