docked to the SelectaDock, a beep sounds. Check
which model of the ThinkPad is docked to the
SelectaDock before maintenance.
2. Verify the Base Model is correctly docked (connected)
to the SelectaDock.
3. Verify the computer is correctly docked (connected) to
the SelectaDock Docking System.
4. Dock a known-good computer to the Base Model and
verify proper operation. If there is a problem, replace
the Base Model.
5. If possible, make sure there are no hardware setting
conflicts, such as in interrupt levels, memory
addresses, DMA channels, and I/O addresses.
6. If the PCI or the ISA card is installed, verify the card
is supported by the computer.
7. Verify the SCSI ID is set correctly.
8. Test and correct any computer problems before you
test it with the SelectaDock Docking System. Use the
computer documentation to resolve any computer
problems.
9. Test the computer with the external keyboard,
external display, mouse, and parallel and serial
device connectors. (Use the keyboard/mouse
connector to test the external keyboard and mouse.)
If no problems are found, connect the external
keyboard, mouse, parallel and serial devices to the
SelectaDock Docking System. Then connect the
SelectaDock Docking System to the computer and
test it.
10. If external devices are attached to the SelectaDock
Docking System, such as an audio amplifier, check
the device by referring to the manual shipped with it.
11. If the user did not bring the computer with a
SelectaDock Docking System when service is
needed, use a computer that works correctly with the
SelectaDock Docking System.
