The power button controls power to the system. The computer receives power
from either the AC adapter connected to an electrical outlet or from up to two
batteries. The system has built-in power management features that remove
power from parts of the computer that are not being used.
Attach the AC power adapter to the computer, whenever possible, to conserve
battery power. When the AC adapter is attached, the battery is charged while
the computer uses AC power.
The Power Menu of the Setup program has power conservation features. To
open the Main Menu of the Setup program, press <F2> during the boot pro-
cess. When activated, each power conservation feature turns off or slows
down one or more functions while the computer is idle.

Standby Time-Out conserves battery power by turning off various devices in
the system, including the display, but leaves the computer ready to resume
operations immediately. Use Standby Time-Out when you leave the com-
puter unattended for less than a few minutes.
Standby Time-Out lets you determine how long the computer remains idle
(no I/O activity) before activating standby mode to conserve battery power.
Settings for this option are Disabled, 1 min., 2 min., 4 min., 6 min., 8 min.,
12 min., and16 min.
To increase battery operating time, set this option to a lower number of min-
utes. Press any key on the built-in keyboard to resume normal computer
operation.

Suspend Time-Out lets you determine how long the computer remains idle
(no I/O activity) before activating suspend mode. Settings for this option are
Disabled, 5 min., 10 min., 15 min., 20 min., 30 min., 40 min., and 60 min.
To increase battery operating time, set this option to a lower number of
minutes.
System Overview 1-7
6XVSHQG0RGH
The Save-to-disk option under Suspend Mode copies all system data to a
reserved area on the hard-disk drive and then turns off all power to the com-
puter. When you resume normal operation, the same programs will be running
and the same files will be open that were loaded before you activated this
mode. Use Save-to-disk suspend mode to conserve battery power or to pre-
serve system data by quickly saving it to the hard-disk drive if you are about to
run out of battery power.

After you perform a visual inspection as described in the previous section, boot
the computer from a diagnostics diskette and, while the boot routine is run-
ning, observe the computer for any indications of problems.
NOTE: To prevent possible damage to the original diagnostics diskette, always
use a backup copy of the diagnostics diskette when servicing a user’s com-
puter. Dell recommends that users make copies of the
Dell Diagnostics
Diskette.
For instructions, see “Before You Start Testing” in Chapter 4, “Run-
ning the Dell Diagnostics,” of the
Dell Inspiron 7000 Reference and
Troubleshooting Guide.
To observe the boot routine, follow these steps:
1. Turn off the computer and any attached peripherals.
2. Insert a diagnostics diskette into the diskette drive. Turn on all peripherals
and then the computer.
3. Watch the indicators at the front of the keyboard. Depending on how your
computer is configured, after various indicators flash momentarily in the
status display panel, some indicators should light up and remain on.
Do these indicators light up within seconds after the boot routine starts?
Yes.
Go to step 4.
No.
Troubleshoot the power subsystem.
4. While the boot routine is running, observe the computer for any of the
following:
Diskette-drive and hard-disk drive access indicator activity
These indicators light in response to data being transferred to or from
the drives. If either of these indicators fails to light during the boot routine,
troubleshoot the diskette drive or hard-disk drive subsystem, as
appropriate.
System error messages
These messages can indicate problems or provide status information. If
a system error message is displayed, refer to Table 3-2.
Beep codes
A beep code is a series of beeps that indicates an error condition. If the
computer emits a beep code, refer to Table 3-1.
Initial Procedures 2-5
NOTE: The computer beeps once shortly after the system boots. This beep is
normal and not part of a beep code.
Any unusual sounds
5. Observe the display for the of the Dell Diagnostics.Diagnostics Menu
Does the Diagnostics Menu appear on the display?
Yes.
See “Running the Dell Diagnostics” in Chapter 3.
No.
Go to step 6.
6. Insert another copy of the diagnostics diskette into the diskette drive and
reboot the computer.
Does the Diagnostics Menu appear on the display?
Yes.
See “Running the Dell Diagnostics” in Chapter 3.
No.
Go to the next section, “Eliminating Resource Conflicts.”
(OLPLQDWLQJ5HVRXUFH&RQIOLFWV
Devices within or connected to the computer may require dedicated memory
spaces, interrupt levels, and/or DMA channels. Because different devices can
be configured at different times, it is possible that the same resource is
assigned to two or more devices.
Disconnect all peripherals and remove all PC Cards to make sure that the com-
puter failure is not caused by faulty devices.
If you suspect that resource conflicts might exist, check the computer and
reassign the resources as necessary. For more information about resolving
conflicts, see Chapter 3, “Troubleshooting Your Computer,” in the
Reference
and Troubleshooting Guide

This chapter describes beep codes and system error messages that can occur
during system start-up or, in the case of some failures, during normal com-
puter operation. The tables in this chapter list faults that can cause a beep
code or system error message to occur and the probable causes of the fault in
each case.
If a faulty computer does not emit beep codes or display system error mes-
sages to indicate a failure, you should load the diagnostics and run the
appropriate tests to help isolate the source of the problem. See “Running the
Dell Diagnostics” found later in this chapter.

If the display cannot display error messages during POST, the computer may
emit a series of beeps that identifies the problem or that can help you identify
a faulty component or assembly. For example, one beep, a burst of three short
beeps, and two more single beeps (beep code 1-3-1-1) means that the system
has encountered a DRAM refresh error condition, probably caused by a faulty
system board.
Table 3-1 lists the beep codes that may be generated during POST. Most beep
codes indicate a fatal error that requires replacement of the main board or
other corrective actions before the computer can operate.

Before starting the Dell Diagnostics, you must configure the computer cor-
rectly. For more information, see “Before You Start Testing” in Chapter 4,
“Running the Dell Diagnostics,” of the
Reference and Troubleshooting Guide
.
Follow these steps to start the diagnostics:
1. Install a CD-ROM drive in the options bay.
2. Turn off the computer.
3. Place a copy of the
Dell Diagnostics Diskette
in the diskette
drive, and boot
the computer.
Starting the diagnostics causes the Dell logo screen to appear, followed by a
message indicating that the diagnostics is loading. Before the diagnostics
loads, a program tests the portion of main memory (RAM) required for loading
the diagnostics. If a main memory error is detected, a message appears on the
screen telling you a memory module has failed.
If no errors are found in main memory, the diagnostics loads, and the Diag-
nostics Menu appears. This menu lets you choose the following options or
exit to the MS-DOS® prompt:
Run All Tests — Runs all tests for a thorough test of the computer
Run Quick Tests — Runs preselected tests to quickly locate a computer
failure or to indicate where further testing is needed to isolate a failure
Run Specific Tests — Tests a particular area or subsystem of the
computer
