Chapter 3: Getting Started
Protecting from power source problems
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
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.
