safety information that shipped with your computer. For
more safety best practices, see the Regulatory Compliance
home page at dell.com/regulatory_compliance.
WARNING: Disconnect all power sources before opening the
computer cover or panels. After you finish working inside
the computer, replace all covers, panels, and screws before
connecting to the power source.
CAUTION: To avoid damaging the computer, make sure that
the work surface is flat and clean.
CAUTION: To avoid damaging the components and cards,

CAUTION: When you disconnect a cable, pull on its connector
or on its pull-tab, not on the cable itself. Some cables have
connectors with locking tabs or thumb-screws that you
must disengage before disconnecting the cable. When
disconnecting cables, keep them evenly aligned to avoid
bending any connector pins. When connecting cables, make
sure that the ports and connectors are correctly oriented
and aligned.
CAUTION: To disconnect a network cable, first unplug the
cable from your computer and then unplug the cable from
the network device.

System Setup
Overview
CAUTION: Unless you are an expert computer user, do not
change the settings in the system setup program. Certain
changes can make your computer work incorrectly.
NOTE: Before you change system setup, it is recommended that you write
down the system setup screen information for future reference.
Use system setup to:
• Get information about the hardware installed in your computer, such as the
amount of RAM, the size of the hard drive, and so on.
• Change the system configuration information.
• Set or change a user-selectable option, such as the user password, type of
hard drive installed, enabling or disabling base devices, and so on.
Entering System Setup
NOTE: You must connect a keyboard and mouse to access and configure
system setup.
1 Turn on (or restart) your computer.
2 During POST, when the Dell logo is displayed, watch for the F2 prompt to
appear and then press F2 immediately.
NOTE: The F2 prompt indicates that the keyboard has initialized. This
prompt can appear very quickly, so you must watch for it, and then
press F2. If you press F2 before the F2 prompt, this keystroke is lost. If
you wait too long and the operating system logo appears, continue to
wait until you see the operating system’s desktop. Then, turn off your
