Before Working Inside Your Computer
Use the following safety guidelines to help protect your computer from potential damage and to help to ensure your personal
safety. Unless otherwise noted, each procedure included in this document assumes that the following conditions exist:
You have performed the steps in Working on Your Computer.
You have read the safety information that shipped with your computer.
A component can be replaced or—if purchased separately—installed by performing the removal procedure in reverse
order.
WARNING: Before working inside your computer, read the safety information that shipped with your
computer. For additional safety best practices information, see the Regulatory Compliance Homepage at
www.dell.com/regulatory_compliance.
CAUTION: Only a certified service technician should perform repairs on your computer. Damage due to
servicing that is not authorized by Dell is not covered by your warranty.
CAUTION: To avoid electrostatic discharge, ground yourself by using a wrist grounding strap or by
periodically touching an unpainted metal surface, such as a connector on the back of the computer.
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: 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; if you are disconnecting this type of cable, press in on the
locking tabs before you disconnect the cable. As you pull connectors apart, keep them evenly aligned to
avoid bending any connector pins. Also, before you connect a cable, ensure that both connectors are
correctly oriented and aligned.
NOTE: The color of your computer and certain components may appear differently than shown in this document.
To avoid damaging your computer, perform the following steps before you begin working inside the computer.
1. Ensure that your work surface is flat and clean to prevent the computer cover from being scratched.
2. Turn off your computer (see Turning Off Your Computer
CAUTION: To disconnect a network cable, first unplug the cable from your computer and then unplug the
cable from the network device.
3. Disconnect all network cables from the computer.
5. Disconnect your computer and all attached devices from their electrical outlets.
6. Press and hold the power button while the system is unplugged to ground the system board.
7. Remove the computer cover (see Removing and Replacing the Computer Cover
).
).
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.

The computer turns off after the operating system shutdown process is complete.
2. Ensure that the computer and all attached devices are turned off. If your computer and attached devices did not
automatically turn off when you shut down your operating system, press and hold the power button for about 6
seconds to turn them off.
, then click the arrow in the lower-right corner of the Start menu as shown below, and then click
After Working Inside Your Computer
After you complete any replacement procedure, ensure you connect any external devices, cards, and cables before turning on
your computer.
1. Replace the computer cover (see Removing and Replacing the Cover
2. Connect any telephone or network cables to your computer.
CAUTION: To connect a network cable, first plug the cable into the network device and then plug it into the
computer.
).
3. Connect your computer and all attached devices to their electrical outlets.
4. Turn on your computer.
5. Verify that the computer works correctly by running the Dell Diagnostics. See Dell Diagnostics

Power Button Light Codes
The power LED located in the power button on the front of the computer illuminates and blinks or remains solid to indicate
five different states:
No light—System is in the off state (S5, or mechanical (AC power not applied) OFF).
Solid Amber—System fault, but Power Supply is good—normal operating state (S0 ).
Blinking Amber—System fault error condition including Power Supply (only +5VSB working), Vreg failure, missing or
bad CPU.
Blinking Green—System is in power saving states S1, S3 or S4. (Blink rate is 1Hz). No fault/error condition.
Solid Green—System is fully functional and is in S0 (ON) state.

Beep Codes
When errors occur during a boot routine that cannot be reported on the monitor, the computer may emit a beep code that
identifies the problem. The beep code is a pattern of sounds: for example, one beep followed by a second beep, then followed
by a burst of three beeps (code 1-1-3) means that the computer was unable to read the data in nonvolatile random-access
memory (NVRAM). If the system loses power and beeps constantly when you turn it back on, the BIOS is probably corrupted.

System Board Schematic
WARNING: Before working inside your computer, read the safety information that shipped with your
computer. For additional safety best practices information, see the Regulatory Compliance Homepage at
www.dell.com/regulatory_compliance.
Your computer's system board offers two jumpers—a password enable jumper and a RTCRST (Real Time Clock Reset) jumper.
Password Enable Jumper
PSWD - Password enable. The system password will be cleared and disabled when the system is started with this jumper
removed.
Pins 1-2 shorted enables password
NVRAM Reset Jumper
RTCRST - Clears NVRAM. The NVRAM will be cleared when the jumper is closed (use the jumper from the password bridge).
To properly clear; AC power must be applied (not necessarily turned on) to the system for about 10 seconds while the jumper
is closed.
Pins 1-2 shorted clears NVRAM
The picture below shows the location of the configuration jumpers on the system board.
NOTE: You can use the RTCRST jumper procedure above to attempt recovery from a No POST, No Video situation.

POST Keystrokes
Your computer has several keystroke options available during the POST process at the Dell™ Logo screen.
Keystroke Function Description
< F2> Enter System Setup Use System Setup to make changes to the user-definable settings.
< F12> or
<Ctrl><Alt><F8>
< F3> Network Boot Bypass the BIOS boot sequence and boot directly to the network
Enter Boot Menu One-time boot and diagnostics utility menu
Boot Menu
As with previous Dell Precision™ workstation platforms, your computer includes a one-time boot menu. This feature offers a
quick and convenient method with which to bypass the System Setup-defined boot device order and boot directly to a specific
device (e.g., floppy, CD-ROM, or hard drive).
The boot menu enhancements introduced on previous platforms are as follows:
Easier access—Although the <Ctrl><Alt><F8> keystroke still exists and can be used to call up the menu, you can
also simply press <F12> during system boot to access the menu.
Diagnostics options—The boot menu includes two diagnostic options, IDE Drive Diagnostics (90/90 Hard Drive
Diagnostics) and Boot to the Utility Partition.
Entering System Setup
Press <F2> to enter System Setup and change the user-definable settings. If you have trouble entering System Setup using
this key, press <F2> when the keyboard LEDs first flash.
Follow the on-screen instructions to view and/or change any settings. On each screen, the system setup options are listed at
the left. To the right of each option is the setting or value for that option. You can change settings that appear as white type
on the screen. Options or values that you cannot change (because they are determined by your Tablet-PC) appear less bright.

improvement over its predecessor, DDR2 SDRAM.
