Before working inside your
computer
NOTE: The images in this document may differ from your computer
depending on the configuration you ordered.
Before you begin
1 Save and close all open files and exit all open applications.
2 Shut down your computer.
The shut-down instruction varies depending on the operating system
installed on your computer.
– Windows 10: Click Start → Power → Shut down.
– Windows 8.1: On the Start screen, click the power icon → Shut
down.
– Windows 7: Click Start → Shut down.
NOTE: If you are using a different operating system, see the
documentation of your operating system for shut-down
instructions.
3 Disconnect your computer and all attached devices from their electrical
outlets.
4 Disconnect all cables such as telephone cables, network cables, and so
on, from your computer.
5 Disconnect all attached devices and peripherals, such as keyboard,
mouse, monitor, and so on, from your computer.
6 Remove any media card and optical disc from your computer, if
applicable.
7 After the computer is unplugged, press and hold the power button for 5
seconds to ground the system board.
Safety instructions
Use the following safety guidelines to protect your computer from potential
damage and ensure your personal safety.
10
WARNING: 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.
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 electrical outlet.
CAUTION: To avoid damaging the computer, ensure that the work
surface is flat and clean.
CAUTION: To avoid damaging the components and cards, handle
them by their edges, and avoid touching pins and contacts.
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 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.
CAUTION: Press and eject any installed card from the media-card
reader.

BIOS setup program
Overview
CAUTION: Unless you are an expert computer user, do not change the
settings in the BIOS setup program. Certain changes can make your
computer work incorrectly.
NOTE: Before you change BIOS setup program, it is recommended that
you write down the BIOS setup program screen information for future
reference.
Use BIOS setup program 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 BIOS setup program
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 is 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.

the computer emits a series of LED codes during the start-up. The system
LED is integrated on the Power button.
The following table shows different light patterns, what they indicate, and the
suggested solutions.
