Flash Memory Update: The flash memory update is required for the following conditions: New versions of system programs New features or options To update the flash memory, do the following: 1. Get the appropriate diskette containing the update. 2. Insert the System Program Service Diskette into drive A and power on the computer. 3. Select Update system programs from the menu. Port Replicator Checkout Use the following procedure to isolate a port replicator problem. The port replicator attaches to the system expansion connector at the bottom of the computer. 1. Power off the computer. 2. Remove the failing devices from the port replicator. 3. Unplug the AC adapter from the port 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 47 and run the diagnostics. 7. If the advanced diagnostic device test did not find an error, suspect a problem with the port replicator of the system expansion bus. 8. Power off the computer and reconnect the port replicator. 9. Power on the computer and run the following advanced diagnostic tests: Serial port test with the wrap plug (P/N 72X8546) installed on the port replicator Universal serial bus test with the test cable (P/N 05K2580) [see "Universal Serial Bus (USB) Test" on page 48] Parallel port test with the wrap plug (P/N 72X8546) installed on the port replicator PC Card (PCMCIA) test with the PC test card (P/N 35G4703) installed FDD-2 device test on the failing device with a scratch diskette 10. If diagnostic errors appear, replace the port replicator or the diskette drive. If the problem remains after the replacement, replace the system board. 11. If power problem appears only when the port replicator is used, replace the port replicator. If power shutdown occurs intermittently when using PC Card devices via a port replicator, suspect an over-current problem. Some PC Card devices use more power; if the maximum usage of each devices occurs simultaneously, the total current will exceed the limit, thereby causing a ThinkPad 560X (2640-60x, 70x) 29

Port Replicator Checkout
Use the following procedure to isolate a port replicator
problem.
The port replicator attaches to the system
expansion connector at the bottom of the computer.
1.
Power off the computer.
2.
Remove the failing devices from the port replicator.
3.
Unplug the AC adapter from the port 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
47 and
run the diagnostics.
7.
If the advanced diagnostic device test did not find an
error, suspect a problem with the port replicator of the
system expansion bus.
