– Windows 8.1: On the Start screen, click or tap the power icon →
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

Safety instructions
Use the following safety guidelines to protect your computer from potential
damage and ensure your personal safety.
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 power source.
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.

WARNING: Before working inside your computer, read the
safety information that shipped with your computer and
follow the steps in Before working inside your computer.

Prerequisites
NOTE: You will hear a low bubbling sound when the computer is turned
on. The sound is standard for all computers with liquid cooling units and
stops after a few minutes of computer use. The bubbling sound is due to
the air that resides in the liquid cooling assembly. When the temperature
of the liquid rises, it expands and the air bubbles in the tube are
dislodged. Alienware X51 being a compact desktop computer, initially the
sound may be more audible as compared to the liquid cooling units in
other larger desktops. The liquid cooling unit dissipates these sounds
after few minutes of use.
