Self Test Error Messages
Error Message
Explanation
Diskette read failure -
strike F1 to try to retry
boot
This message indicates the disk is defective or not formatted.
Try another known good formatted disk and press F1. Fixed disk failure
This message indicates the system disk drive failed to complete the self test or that
the nonvolatile random-access memory (NVRAM) is configured incorrectly for the
installed drive type.
Ensure that the notebook is configured to boot from the C: Drive.
Press Ctrl-Alt-Esc to ensure that the hard disk drive type is correctly identified in
Setup (should be default for the internal hard disk drive).
Press the Ctrl-Alt-Del keys to attempt to reboot the system. If the error occurs a
second time, run the diagnostics as described in Paragraph 5.4.
Fixed disk read failure
- strike F1 to retry boot
This message indicates that the hard disk drive improperly formatted, or that a
hardware failure has occurred in the hard disk drive subsystem.
Press Ctrl-Alt-Esc to ensure that the hard disk drive type is correctly identified in
Setup (should be default for the internal hard drive).
If the booting process still fails, run the diagnostics as described in Paragraph 5.4.
Invalid configuration
information
This message indicates the computer has been configured incorrectly. Check the
settings in the Setup program menu. Also, NVRAM battery failure (resulting in loss
of configuration data) can generate this error message. Install an AC adapter and
recharge the system. If the problem persists, replace Top Board.
Keyboard clock/data
line failure
This message indicates either the keyboard or the external keyboard (if one is
installed) is defective. If the computer has an external keyboard connected, check
the connection to ensure that it is connected correctly.
Keyboard stuck key
failure
This message indicates the self test has detected a stuck key on the keyboard. Try
the keyboard keys to determine if they appear to be working properly and reboot
the computer.
Note: Also, ensure that no key is pressed during power up and that no keys are
jammed.
If the self test still fails, execute the diagnostics as described in Paragraph 5.4.
No boot device
available - press F1 to
retry boot.
This message indicates the system disk, the disk drive, or the disk is defective (if
loading MS-DOS from disk) or that the NVRAM is not correctly configured for the
installed disk drive type. Replace the disk and reboot the computer.
No boot sector on
system disk - press F1
to retry boot
This message indicates the system disk is not formatted. Try powering down the
system and re-running the self test. Press Ctrl-Alt-Esc to ensure that the drive type
is correctly set in Setup. Also, press F1 to try loading MS-DOS from the hard disk
drive again. If the message persists, the disk must be reformatted and software
reloaded from disks (refer to Chapter 3).
Non-System Disk or
Disk error. Replace
and press any key
when ready.
This message indicates the disk installed in floppy disk Drive A is not a bootable
disk. Format an MS-DOS bootable disk and install the disk in Drive A, Reboot the
computer. Also try pressing Ctrl-Alt-Esc to ensure the disk drive type is correctly
set in Setup.
Time-of-day clock
stopped
This message indicates that the battery sustaining the system configuration has
failed. Reset the configuration.
Note: The following messages are informational messages that do not necessarily
indicate a self test failure.
NNN Main Memory,
NNN Extended
This message lists the amount of standard memory and optional extended memory
that has tested successfully during self test execution. This message is only
displayed if Quick Boot is off in System Setup.
Memory tests
terminated by
keystroke
This message tells you that you have pressed the Space Bar while the memory
tests were running. Pressing the Space Bar during memory testing stops the tests.
