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.

Checking the voltage selection

Caution

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 computer.

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.

A power supply is integrated into your computer to provide power to the system board, add-in cards, and peripheral devices. The voltage selection for your location is typically set at the factory. Use the power selection switch on the back of your computer to set the power supply to 115V or 230V. To verify that your system has the correct setting for your environment, check the voltage selection switch.

To set the voltage selection switch:

■Use a tool such as an opened paper clip to slide the voltage selection switch to the correct voltage position. For the location of the switch, see your setup poster or hardware reference.

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.

Waking up your computer

Tips & Tricks

For more information about changing the power button mode, see “Changing power-saving settings” on page 114.

To start your computer:

1Connect the cables to your computer according to the setup poster.

2Turn on your computer.

3If you are starting your computer for the first time, follow the on-screen instructions to set up your computer.

4Attach and turn on any peripheral devices, such as printers or scanners, and see the documentation that came with the device for setup instructions.

When you have not used your computer for several minutes, it may enter a power-saving mode called Standby. While in Standby, the power indicator flashes.

If your computer is in Standby mode, move the mouse or press the power button to “wake” it up.
