Safety instructions
Use the following safety guidelines to protect your computer from potential damage and to ensure your personal safety. Unless
otherwise noted, each procedure included in this document assumes that you have read the safety information that shipped
with your computer.
NOTE:
Before working inside your computer, read the safety information that shipped with your computer. For more safety
best practices, see the Regulatory Compliance home page at www.dell.com/regulatory_compliance.
NOTE: 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 electrical outlet.
CAUTION: To avoid damaging the computer, ensure that the work surface is flat and clean.
CAUTION: Handle components and cards with care. Do not touch the components or contacts on a card. Hold a
card by its edges or by its metal mounting bracket. Hold a component such as a processor by its edges, not by
its pins.
CAUTION: You should only perform troubleshooting and repairs as authorized or directed by the Dell technical
assistance team. Damage due to servicing that is not authorized by Dell is not covered by your warranty. See the
safety instructions that shipped with the product or at www.dell.com/regulatory_compliance.
CAUTION: Before touching anything inside your computer, ground yourself by using a wrist grounding strap or
by periodically touching an unpainted metal surface, such as the metal at the back of the computer. While you
work, periodically touch an unpainted metal surface to dissipate static electricity, which could harm internal
components.
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, ensure that the ports and connectors are correctly oriented and aligned.

System setup
NOTE: Depending on the computer and its installed devices, the items listed in this section may or may not be displayed.
Boot Sequence
Boot sequence enables you to bypass the System Setup–defined boot device order and boot directly to a specific device (for
example: optical drive or hard drive). During the Power-on Self-Test (POST), when the Dell logo appears, you can:
● Access System Setup by pressing F2 key
● Bring up the one-time boot menu by pressing F12 key.
The one-time boot menu displays the devices that you can boot from including the diagnostic option. The boot menu options
are:
● Removable Drive (if available)
● STXXXX Drive
NOTE: XXXX denotes the SATA drive number.
● Optical Drive (if available)
● SATA Hard Drive (if available)
● Diagnostics
NOTE: Choosing Diagnostics, displays the SupportAssist screen.
The boot sequence screen also displays the option to access the System Setup screen.
