Line Conditioners
NOTICE: Line conditioners do not protect against power interruptions.
Line conditioners are designed to maintain AC voltage at a fairly constant level.
Uninterruptible Power Supplies
NOTICE: Loss of power while data is being saved to the hard drive may result in data loss or file damage.
NOTE: To ensure maximum battery operating time, connect only your computer to a UPS. Connect other
devices, such as a printer, to a separate power strip that provides surge protection.
A UPS protects against power fluctuations and interruptions. UPS devices contain a battery that
provides temporary power to connected devices when AC power is interrupted. The battery charges
while AC power is available. See the UPS manufacturer documentation for information on battery
operating time and to ensure that the device is approved by Underwriters Laboratories (UL).
Turning Off Your Computer
NOTICE: To avoid losing data, save and close any open files and exit any open programs before you shut
down the computer.
NOTE: As an alternative to turning off your computer, you can set your computer to enter standby or
hibernate mode. For more information, see the Dell Inspiron Help file. To access the help file, see page 16.
