General Preparation
1. Check that the computer is correctly docked
(connected) to the Dock I.
2. If possible, make sure that there are no hardware
conflicts settings, such as interrupt levels, memory
address, DMA channel, and I/O address.
3. Check that the SCSI ID is set correctly.
4. Test and correct any computer problem before you
test it with the Dock I. Use the computer
documentation to resolve any computer problems.
5. 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
Dock I, then connect the Dock I to the computer and
test it.
6. If external devices are attached to the Dock I, such as
an audio amplifier, check the device by referring to
the manual shipped with the device.
7. When the release/lock lever is opened with the
computer docked on the Dock I and power is on, a
warning is indicated by a warning beep and a LED
message. If either do not work, the problem is in the
LED or the warning system.
8. If the user did not bring the computer with the Dock I
when service is needed, use a computer that works
correctly with the Dock I.
9. If a beep sounds when the computer is docked to the
Dock I, make sure that the following are correct.
The release/lock lever is not open.
The computer is not in suspend mode while
docked to the Dock I.
If the beep sounds during normal operation, dock the
Dock I to another computer and do the same
operation again. If the beep sounds, suspect a
problem with the Dock I.
