Safety Instructions
Use the following safety guidelines to help protect your computer from potential damage and to ensure your own personal safety.
When Using Your Computer
As you use your computer, observe the following safe-handling guidelines.
CAUTION: Do not operate your computer with any cover(s) (including computer covers, bezels, filler brackets, front-panel inserts, and so on)
removed.
l
To help avoid damaging your computer, be sure the voltage selection switch on the power supply is set to match the AC power available at your
location.
¡
115 volts (V)/60 hertz (Hz) in most of North and South America and some Far Eastern countries such as South Korea and Taiwan
¡
100 V/50 Hz in eastern Japan and 100 V/60 Hz in western Japan
NOTE: The voltage selection switch must be set to the 115V position even though the AC supply in Japan is 100 V.
¡
230 V/50 Hz in most of Europe, the Middle East, and the Far East
NOTE: Auto-select power supplies do not require a voltage selection switch. Your power supply may not have this switch.
Also be sure that your monitor and attached devices are electrically rated to operate with the AC power available in your location.
l
Before working inside the computer, unplug the computer to help prevent electric shock or system board damage. Certain system board components
continue to receive power any time the computer is connected to AC power.
l
To help avoid possible damage to the system board, wait 15 seconds after turning off the computer before disconnecting a device from the computer.
l
To help prevent electric shock, plug the computer and device power cables into properly grounded power sources. These cables are equipped with
three-prong plugs to help ensure proper grounding. Do not use adapter plugs or remove the grounding prong from a cable. If you must use an
extension cable, use a three-wire cable with properly grounded plugs.
l
To help protect your computer from sudden, transient increases and decreases in electrical power, use a surge suppressor, line conditioner, or
uninterruptible power supply (UPS).
l
Be sure nothing rests on your computer's cables and that the cables are not located where they can be stepped on or tripped over.
l
Do not spill food or liquids on your computer. If the computer gets wet, consult your Owner's Manual.
l
Do not push any objects into the openings of your computer. Doing so can cause fire or electric shock by shorting out interior components.
Keep your computer away from radiators and heat sources. Also, do not block cooling vents. Avoid placing loose papers underneath your computer; do
not place your computer in a closed-in wall unit or on a bed, sofa, or rug.
When Working Inside Your Computer
Before you open the computer cover, perform the following steps in the sequence indicated.
CAUTION: Do not attempt to service the computer yourself, except as explained in your online Dell documentation or otherwise provided to you.
Always follow installation and service instructions closely.
NOTICE: To help avoid possible damage to the system board, wait 5 seconds after turning off the computer before removing a component from the
system board or disconnecting a device from the computer.
1.
Perform an orderly computer shutdown using the operating system menu.
2.
Turn off your computer and any devices.
3.
Ground yourself by touching an unpainted metal surface on the chassis, such as the metal around the card-slot openings at the back of the computer,
before touching anything inside your computer.
While you work, periodically touch an unpainted metal surface on the computer chassis to dissipate any static electricity that might harm internal
components.
4.
Disconnect your computer and devices from their power sources. Also, disconnect any telephone or telecommunication lines from the computer.
Doing so reduces the potential for personal injury or shock.
In addition, take note of these safety guidelines when appropriate:
l
When you disconnect a cable, pull on its connector or on its strain-relief loop, not on the cable itself. Some cables have a connector with locking tabs; if
you are disconnecting this type of cable, press in on the locking tabs before disconnecting the cable. As you pull connectors apart, keep them evenly
aligned to avoid bending any connector pins. Also, before you connect a cable, make sure both connectors are correctly oriented and aligned.
l
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 microprocessor chip by its edges, not by its pins.
There is a danger of a new battery exploding if it is incorrectly installed. Replace the battery only with the same or equivalent type recommended by the
manufacturer. Discard used batteries according to the manufacturer's instructions.
Protecting Against Electrostatic Discharge
Static electricity can harm delicate components inside your computer. To prevent static damage, discharge static electricity from your body before you touch
any of your computer's electronic components, such as the microprocessor. You can do so by touching an unpainted metal surface on the computer chassis.
As you continue to work inside the computer, periodically touch an unpainted metal surface to remove any static charge your body may have accumulated.
You can also take the following steps to prevent damage from electrostatic discharge (ESD)
l
When unpacking a static-sensitive component from its shipping carton, do not remove the component from the antistatic packing material until you are
ready to install the component in your computer. Just before unwrapping the antistatic packaging, be sure to discharge static electricity from your body.
l
When transporting a sensitive component, first place it in an antistatic container or packaging.
l
Handle all sensitive components in a static-safe area. If possible, use antistatic floor pads and workbench pads.
