Battery; Battery Status; Bios Version; Boot Sequence - Dell Latitude CP Reference And Troubleshooting Manual

The value selected for Audio Mode determines the boot
configuration for the device. If Windows 95 finds other
available resources, the operating system may upgrade
the configuration.

Battery

Battery is one of the categories of Power Management
You can set different time-outs for the following options
when you operate your computer from battery power:
Display Time-Out, Disk Time-Out, Suspend Time-Out
S2D Time-Out, Smart CPU Mode, and Brightness.
A change to the Battery option takes effect immediately
(rebooting is not required).

Battery Status

Battery Status (Page 3 of the System Setup screens) is a
graphical representation of the approximate amount of
charge left in the main and secondary batteries. There are
no user-selectable settings for this option. If there is no
battery installed in the main battery compartment or in
the modular Bay, the battery gauge illustration says
Battery Status: Not Installed.
If you are not in the System Setup program, you can see
the battery gauge illustration at any time by pressing
<Fn><F3>.

BIOS Version

BIOS Version displays the version number and release
date of the BIOS in your computer. A service technician
may ask you for this version number if you call Dell for
technical assistance.
NOTE: Dell may periodically offer revisions of the BIOS
that add features or solve specific problems. Because the
BIOS for your computer is stored on a reprogrammable
flash-memory chip, you can use the Flash BIOS Update
program to update your computer's BIOS entirely
through software.

Boot Sequence

Boot Sequence determines which disk device your com-
puter uses to find the software needed to start the
operating system.
The term boot refers to the computer's start-up proce-
dure. When you turn on the computer, it "bootstraps"
2-6 Dell Latitude CP Reference and Troubleshooting Guide
itself into an operational state by loading into memory a
small program, which in turn loads the necessary operat-
ing system. Boot Sequence tells the computer where to
find the files that it needs to load.
Settings for this option are:
•
Diskette First (the default) — Causes your computer
to attempt first to boot from a bootable diskette
.
If the computer detects no diskette in the diskette
drive, it tries to boot from the hard-disk drive. If the
,
computer encounters a diskette without the required
boot files or detects a problem with the diskette
drive, it displays an error message.
•
Hard Disk Only — Causes your computer to boot
only from the hard-disk drive
If it fails to boot from the hard-disk drive for any rea-
son, your computer does not attempt to boot from the
diskette drive.
For a change in the Boot Sequence option to take effect,
you must reboot your computer.

Boot Speed

Boot Speed allows you to choose between the computer's
processing speed (the default) and Compatible, a slower
compatibility speed. The compatibility speed varies,
depending on the configuration of your system.
When you change the setting in the Boot Speed option,
the System Setup program stores and continues to display
the new setting even if you do not reboot your computer
when you exit the System Setup program. If you start the
System Setup program again during your current work
session, the processing speed displayed for the Boot
Speed option may not match the actual speed at which
your computer is running.
For a change in the Boot Speed option to take effect, you
must reboot your computer.

Brightness

Brightness allows you to select the brightness of the
display when the computer is operating on battery power.
Use the left- and right-arrow keys to change the bright-
ness of the display. When the computer is powered by a
battery, the default setting for Brightness is the minimum.
If the computer is using AC power, the default setting is
maximum.
