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 key. 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 test menu, the device is defective. 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: 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 a dark shade, because the icons represent subsystems of the system board and not the attachment of the devices. The FDD-1 icon represents the first drive in the system configuration for each type of device. For Model 560Z, FDD-1 represents an external diskette drive attached through the external diskette drive connector. Similarly, the FDD-2 icon represents the second drive, usually attached through a port replicator. ThinkPad 560Z HMM 35

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 test
menu, the device is defective.
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:
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 a
dark shade, because the icons represent subsystems of
the system board and not the attachment of the devices.
The FDD-1 icon represents the
first
drive in the system
configuration for each type of device.
For Model 560Z,
FDD-1 represents an external diskette drive attached
through the external diskette drive connector.
Similarly,
the FDD-2 icon represents the
second
drive, usually
attached through a port replicator.
