Laptop User Manual

If a device that is not installed appears in dark shade (for
example, FDD-2 appears in dark shade when no second
FDD is installed), do the following:
1. Replace the first device in the configuration, such as
an FDD-1.
2. If the problem persists, replace the system board.
The Parallel, and Serial icons are always displayed in dark
shade, because the icons represent subsystems of the
system board, not the attachment of devices.
The FDD-1 icon represents the first drive in the system
configuration for each type of device. The FDD-2 icon
represents the second drive, attached through a port
replicator.
Diagnostic Error Codes
If an error is detected, the following appears:
Large X on the left side of the device icon.
Device ID (three digits)
Error code (two digits)
FRU code (four digits)
For example:
The device ID and error code indicate the detailed portion
of the FRU that caused the error. If replacing a FRU does
not correct the problem, see the device ID or error code
from the previous failure. If they changed, the new FRU
might be defective, or it may have been incorrectly
installed.
Device ID: If an error is detected by the diagnostic
tests, a three-digit device ID is displayed, indicating the
suspected device.
