As you use your computer, observe the following safe-handling guidelines. For comfort and efficiency, observe the ergonomic guidelines provided in
�Ergonomic Computing Habits� in the Owner�s Manual.
CAUTION: Do not operate your computer with any cover(s) (including the computer cover, filler brackets, front-panel inserts, and so on) removed.
Your computer is equipped with either an auto-sensing voltage selector or a manual voltage-selection switch. Computers with an auto-sensing voltage selector do not have a voltage-selection switch on the back panel and automatically detect the correct operating voltage. Computers with a voltage-selection switch on the back panel must be manually set to operate at the correct operating voltage. To help avoid damaging a computer with a manual voltage-selection switch, be sure that the voltage-selection switch is set to match the AC power available at your location:
115 V/60 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.
To help prevent damage to your computer when disconnecting a network cable from your computer, first unplug the cable from the computer network connector and then from the network wall jack. When reconnecting a network cable to your computer, first plug the network cable into the network wall jack and then into the computer network connector.
To help avoid possible damage to the system board, wait 5 seconds after turning off the computer before disconnecting or connecting a non-USB device.
To help prevent electric shock, plug the computer and device power cables into properly grounded power sources. These cables are equipped with 3-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 3-wire cable with properly grounded plugs.
To help protect your computer from sudden, transient increases and decreases in electrical power, use a surge suppressor, line conditioner, or uninterruptable power supply.
Be sure that nothing rests on your computer cables and that the cables are not located where they can be stepped on or tripped over.
Do not spill food or liquids on your computer. If the computer gets wet, contact Dell.
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.
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

HINT: Do not discard the blower; reuse the
blower. Your microprocessor upgrade kit from Dell includes only a
replacement heat sink and two replacement securing clips.
NOTICE: Be careful not to bend any of the pins
when you remove the microprocessor from its socket. Bending the pins can
permanently damage the microprocessor.
Your microprocessor socket is a zero
insertion force (ZIF) socket with a lever-type handle that secures the
microprocessor in, or releases it from, the socket.
Pull the release lever straight up until the
microprocessor is released, and then remove the microprocessor from the
socket.
Leave the release lever extended so that the socket
is ready for the new microprocessor.

If any of the pins on the microprocessor
appear to be bent, see "Contacting Dell" in the Owner's
Manual for instructions on obtaining technical assistance.
Align the pin-1 corner of the microprocessor with the
pin-1 corner of the socket.
HINT: You must identify the pin-1 corner to
correctly position the microprocessor.
NOTICE: You must position the microprocessor
correctly in the socket to avoid permanent damage to the microprocessor
and the computer when you turn on the computer.
If
the release lever on the socket is not fully extended, move it to that
position now.
With the pin-1 corners of the microprocessor and
socket aligned, align the pins on the microprocessor with the holes in the
socket.
NOTICE: When you place the microprocessor in
the socket, be sure that all of the pins go into the corresponding holes
on all sides of the socket. Be careful not to bend the pins.
Set
the microprocessor lightly in the socket and make sure that all pins are
headed into the correct holes. Because your computer uses a ZIF socket, there
is no need to use force (which could bend the pins if the microprocessor is
misaligned). When the microprocessor is positioned correctly, press it with
minimal pressure to seat it.
When the microprocessor is fully seated in the
socket, pivot the release lever back toward the socket until it snaps into
place, securing the microprocessor.
