3.4.7 Recharging the Battery Packs
A standalone battery charger option is available to charge notebook battery
packs. The battery packs may also be charged in the notebook as follows: 
1.Install the battery pack in your computer (if not already installed).
2.Connect the AC Adapter as described in Section 2. The LEDs on the
battery pack(s) will gradually light starting from the left.  When all
four LEDs on the battery pack light, this indicates that the battery
pack is at least 90% charged.  All four LEDs...

3.4.11 Rebuilding the System Software
In the event of a hard drive replacement or system board replacement which
resulted in loss of system software, you may need to rebuilt the entire
system software structure. 
The following items are required to rebuild the system software:
·Set of  22 backup diskettes of the system software (international
versions require 23 diskettes)
·System Recovery Diskette- contains Backup/Restore Utilities, key
system files and advanced diagnostics for performing system...

Troubleshooting Procedures
This section provides an overview of the fault isolation process, provides
guidelines for isolating computer malfunctions to replaceable subassemblies
and provides instructions for executing diagnostics and interpreting error
messages. 
4.1 Overview of Fault Isolation
Process
The fault isolation process  (summarized in Figure 4-1) consists of the
following: 
·Quick Check of the following:
·Notebook power system (including battery packs and AC
Adapter connections)- See...

The detailed block diagram, shown in Figure 4-2, is useful in performing
fault analysis of various internal subsystems. For example, a sound
hardware problem can be traced to either the PCMCIA/Sound Board, the
main board, or the interconnecting cabling software. A front panel LED
problem can be the LED Board, Main Board or interconnecting cabling
between the two. Other subsystem problems can be isolated in a similar
fashion using the detailed block diagram as a troubleshooting tool.

4.2 Troubleshooting Procedures
The built-in self test program and the disk resident diagnostics program
(PC-Doctor) are useful tools in computer troubleshooting. However, if the
computer has a power, keyboard or display problem, you first solve this
problem before running diagnostics. If the computer powers up and displays
messages on the LCD or emits a series of beeps, skip to Paragraph 4.2.3 for
further instructions. 
4.2.1 Troubleshooting a Power Supply
Problem
If the computer does not power up when...

·Notebook Set for External Monitor- use VGA or WinMode Utility
command to reset notebook. 
·LCD - Replace the cover-display assembly as described in Section 5 of
this manual. 
·Low battery - Use a fully charged battery.
4.2.3 Fault Isolation Using Selftest 
When the computer is first powered up, it automatically performs a self-test
of its central hardware and memory functions. During self-test (which lasts
for a few seconds), the display shows copyright and version number
information.

Table 4-1  Self-Test Error Messages
Diskette drive 0 failure
This message indicates the internal floppy diskette (drive A) has failed. Press
CTRL-ALT-ESC to ensure that drive type is correctly set (3.5 inch, 1.44MB).
Run the Diagnostics to check drive A as described in Paragraph 4.2.5.  Also
try using a new, correctly formatted diskette.
Diskette read failure - strike F1 to try to retry boot
This message indicates the diskette is defective or not formatted. 
Try another known good formatted diskette and...

If the self-test still fails, execute the diagnostics as described in paragraph
4.2.5.
No boot device available - press F1 to retry boot 
This message indicates the system disk, the diskette drive, or the diskette is
defective (if loading MS-DOS from diskette) or that the NVRAM is not
correctly configured for the installed disk drive type. Replace the diskette
and reboot the computer. If the self-test still fails, run the diagnostics as
described in paragraph 4.2.5.
No boot sector on system disk - press...

4.2.3.2 Self Test Beep Error Messages
In the event of a hardware problem that affects the display, the Notebook
also communicates errors via a series of beeps. These codes may be heard
over the system’s speaker as three bursts of beeps. The interpretation of the
beep codes is provided in Table 4-2. 
To recover from a self test error, try cycling power to the computer.  Also,
press CTRL-ALT-ESC to ensure that the Setup configuration is correct. In
general, most of the failures are associated with the Main...
