Running the Diagnostics
USB ports of the docking station and click on USB-3
and USB-4.
Displaying the Error Log
Diagnostic errors are printed on a printer attached to the
parallel port when the error is detected. The error is also
logged in the system memory.
Use the following procedure to display the errors:
1. Enter the advanced diagnostic test.
2. Press Ctrl+E.
3. The error log appears.
4. To exit the screen, click on Exit or press Esc.
The error log is not saved when system power is turned
off.
Checking the Installed Devices List
If a device is installed but the icon appears in a gray shade
rather than a dark shade on the basic diagnostics menu,
the device is defective. If necessary, adjust the contrast
control to clearly distinguish the shades of the icon.
Reseat the device connectors. If the symptom remains,
replace the device or the system board.
If a device that is not installed appears in a dark shade (for
example, FDD-2 appears in a dark shade when

no

second
FDD is installed), do the following:
Note: Some ThinkPad 600E computers support only one
FDD at a time. The icon of the diskette drive for
such models is FDD instead of FDD-1 or FDD-2.
1. Replace the first device in the configuration, such as
an FDD-1.
2. If the problem persists, replace the card that the
device is connected to.
The Parallel, and Serial icons are always displayed in a
dark shade, because the icons represent subsystems of
the system board and not the attachment of devices.
The FDD-1 icon represents a device in the computer. The
FDD-2 icon represents another device, such as:
An external diskette drive attached to the computer
An external diskette drive attached to a port replicator
A diskette drive in a docking station
