IBM ThinkPad 380XD Hardware Maintenance Manual

Drifting Pointer
There may be cases when the pointer drifts for a
short while on the screen, this is not a hardware
problem. This movement can occur when a
slight, steady pressure is applied to the
TrackPoint III pointer. No service action needs
be taken.
4. Go to the Easy-Setup menu.
5. Move to an item with the pointing stick.
6. Press any one of the two click buttons.
7. Verify that the item is selected.
8. Verify that all buttons work correctly.
9. If the problem still persists, do the following one at a
time:
Warning: Do not replace a nondefective FRU.
 Reseat the TrackPoint III cable.
 Replace the keyboard.
 Replace the DC/DC card.
 Replace the system board.
Optional Device Checkout
If you suspect an optional device problem, do either of the
following:
 “Port Replicator Checkout”
 “External Monitor Self-Test”
Port Replicator Checkout
Do the following procedures to isolate a port replicator
problem. A port replicator attaches to the system
expansion connector at the rear of the computer.
1. Turn off the computer.
2. Remove the failing devices from the replicator.
3. Unplug the AC adapter from the replicator, if
attached.
4. Remove the port replicator from the computer.
5. Reconnect the failing device directly to the computer.
(If another device is already connected to the
computer, remove it first.)
6. Go to the “Running the Diagnostics” on page 49 and
run the diagnostics.
7. If the advanced diagnostic device test does not find
an error, suspect a problem with the port replicator of
the system expansion bus.
8. Turn off the computer and reconnect the port
replicator.
9. Turn on the computer and run the following advanced
diagnostic tests:
