correctly set (3.5 inch, 1.44 MB).
Run the Diagnostics to check Drive A as described in Paragraph 5.4. Also try
using a new, correctly formatted disk.
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

. 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. If the problem
still exists, run the diagnostics as described in Paragraph 5.4.
Keyboard stuck key failure
This message indicates the self test has detected a stuck key on the keyboard.
