Protecting from power source problems
Warning
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.
During a power surge, the voltage level of
electricity coming into your computer can
increase to far above normal levels and cause
data loss or system damage. Protect your
computer and peripheral devices by connecting
them to a
surge protector
, which absorbs voltage
surges and prevents them from reaching your
computer.
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 save
your work and shut down your computer
normally.
Starting your computer
To start your computer:
1
Connect the cables to your computer
according to the setup poster.
2
Press the power button on the front of 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.
3
If you are starting your computer for the
first time, follow the on-screen instructions
to set up your computer.
4
Attach and turn on any peripheral devices,
such as printers or scanners, and see the
documentation that came with the device
for setup instructions.
