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 screen,
the device is defective. Reseat the device connectors. If
the symptom remains, replace the device or the system
board. If needed, adjust the contrast control to clearly
distinguish the shades of the icon.
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:
1. Replace the first device in the configuration, such as
an FDD-1, HDD-1, or PCMCIA-1.
2. If the problem remains, replace the system board.
The PCMCIA-1, 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
the devices.
The FDD-1, HDD-1, or PCMCIA-1 icons represent the first
drive in the system configuration for each type of device.
Similarly, the HDD-3, FDD-2, or PCMCIA-2 icons represent
the second drive, usually attached through a port
replicator or an expansion unit. The HDD-2 icon
represents the hard disk drive in the UltraBay.
Printer
Test the printer by connecting it to the computer before
testing it on the IBM ThinkPad Dock I.
1. Make sure the printer is correctly connected and the
power is turned on.
2. Run the printer self-test.
If the printer self-test does not run correctly, the problem is
in the printer. Refer to the printer service manual.
If the printer self-test runs correctly, connect a wrap plug
on the parallel connector on the rear of IBM ThinkPad
Dock I and run the advanced diagnostic tests to determine
the failing FRU.
If the advanced diagnostic tests (with the wrap plug
connected) did not detect a failure, replace the printer
cable.
If the problem is not corrected, do one of the following:
If the printer is attached to the parallel connector of
IBM ThinkPad Dock I, replace the main card of IBM
ThinkPad Dock I.
If the printer is attached to the parallel connector on
the adapter, replace the FRUs in the following order
one at a time until the problem is corrected:
