CHAPTER 2: Using Your Computer

Protecting from power source problems

High voltages can enter your computer
through both the power cord and the
modem connection. Protect your
computer by using a surge protector. If
you have a telephone modem, use a
surge protector that has a modem jack. If
you have a cable modem, use a surge
protector that has an antenna/cable TV
jack. During an electrical storm, unplug
both the surge protector and the modem.

Checking the voltage selection

If you set the voltage selection switch
incorrectly, your system will be damaged.
Make sure this switch is set correctly for
your location before turning on your
In the United States, the utility power is
supplied at a nominal 115 volts at 60 Hz.
The power supply should always be set to
this when your computer is operating in
the United States. In other areas of the
world, such as Europe, the utility power is
supplied at 230 volts at 50 Hz. If your
computer is operating in an environment
such as this, the voltage switch should be
moved to 230.

Starting your computer

Important
Your computer has a built-in variable
speed fan. In addition, your computer
uses a powerful processor which
produces heat. Both the system fan and
processor can run at different speeds at
times to ensure proper system cooling.
You may notice an increase in the fan
noise when the fan is running at high
speed and a decrease in the fan noise
when it switches to normal speed.

An uninterruptible power supply (UPS) supplies battery power to your computer
during a power failure. Although you cannot run your computer for an extended
period of time with a UPS, a UPS lets you run your computer long enough to
