FRU replacement notices
This section contains notices for removal and replacement.
Read this section carefully before replacing any FRU.
  Screw notices
Loose screws can cause a reliability problem. The an IBM
ThinkPad computer address this problem with special
nylon-coated screws that have the following characteristics:

They maintain tight connections.

They do not easily come loose, even with shock or
vibration.

They need additional force to tighten.

They should be used only once.
Do the following when you service this machine:

Keep the screw kit (P/N 05K4841) in your tool bag.

Always use new screws.

Use a torque screwdriver if you have one.
Tighten screws as follows:

Plastic to plastic
Turn an additional 90 degrees after the screw head
touches the surface of the plastic part:

Logic card to plastic
Turn an additional 180 degrees after the screw head
touches the surface of the logic card:
 
Torque driver
If you have a torque driver, refer to the “Torque”
column with each step.

Make sure you use the correct screw. If you have a
torque screwdriver, tighten all screws firmly to the

Retaining serial numbers
This section includes the following descriptions:

“Restoring the serial number of the system unit”

“Retaining the UUID”
Restoring the serial number of the system
unit:
When the computer was manufactured, the
EEPROM on the system board was loaded with the serial
numbers of the system and all major components. The
numbers need to remain the same throughout the life of
the computer.
When you replace the system board, you must restore the
system unit serial number to its original value.
Before replacing the system board, save the original serial
number by doing the following:
1. Install the ThinkPad Hardware Maintenance Diskette
Version 1.60 and restart the computer.
2. From the main menu, select 1. Set System
Identification.
3. Select 2. Read S/N data from EEPROM.
The serial number for each device is displayed. Write
down the serial number of the system unit, designated as
follows:
20: System unit serial number
After you have replaced the system board, restore the
serial number by doing the following:
1. Install the ThinkPad Hardware Maintenance Diskette
Version 1.60 and restart the computer.
2. From the main menu, select 1. Set System
Identification.
3. Select 1. Add S/N data from EEPROM.
Follow the instructions on the screen.
Note:  The serial number of the system unit is written on
the label attached on the bottom of the computer.
Retaining the UUID:  The Universally Unique
Identifier (UUID) is a 128-bit number uniquely assigned to
your computer at production and stored in the EEPROM of
your system board. The algorithm that generates the
unique number is designed to provide unique IDs until the
year A.D. 3400. No two computers in the world have the
same number.
When you replace the system board, you must set the
UUID on the new system board as follows:

1. Install the ThinkPad Hardware Maintenance Diskette
Version 1.60, and restart the computer.
2. Select 4. Assign UUID from the main menu.
A new UUID is created and written. If a valid UUID
already exists, it is not overwritten.

							Removing and replacing a FRU
Removing and replacing a FRU
This section presents information and drawings for use in
removing and replacing a FRU. Be sure to observe the
following general rules:
1. Do not try to service the computer unless you have
been trained and certified. An untrained person runs
the risk of damaging parts.
2. Before replacing any FRU, review “FRU replacement
notices” on page 48.
3. Begin by removing any FRUs that have to be
removed before the failing FRU. Any such FRUs are
listed at the top of the page. Remove them in the
orders in which they are listed.
4. Follow the correct sequence in the steps for removing
the FRU, as indicated in the drawings by the numbers
in square callouts.
5. When turning a screw to replace a FRU, turn it in the
direction indicated by the arrow in the drawing.
6. When removing the FRU, move it in the direction
indicated by the arrow in the drawing.
7. To put the new FRU in place, reverse the removal
procedure and follow any notes that pertain to
replacement. For information about connecting and
arranging internal cables, see “Locations” on
page 94.
8. When replacing a FRU, use the correct screw as
shown in the procedures.
Safety Notice 1: Translation on page 4
Before the computer is powered on after FRU
replacement, make sure all screws, springs, and other
small parts are in place and are not loose inside the
computer. Verify this by shaking the computer gently
and listening for rattling sounds. Metallic parts or
metal flakes can cause electrical short circuits.
Safety Notice 3: Translation on page 6
The battery pack contains small amounts of nickel.
Do not disassemble it, throw it into fire or water, or
short-circuit it. Dispose of the battery pack as
required by local ordinances or regulations.
Safety Notice 8: Translation on page 10
Before removing any FRU, power off the computer,
unplug all power cords from electrical outlets, remove
the battery pack, and then disconnect any
interconnecting cables.

 Attention 
The system board is sensitive to, and can be
damaged by, electrostatic discharge. Establish
personal grounding by touching a ground point with
one hand before touching these units.
You must use electrostatic discharge (ESD) strap (P/N
6405959) to establish personal grounding.

  1020 Backup battery
Safety Notice 4: Translation on page 7
The backup battery is a lithium battery and can cause
a fire, an explosion, or severe burns. Do not recharge
it, remove its polarized connector, disassemble it, heat
it above 100°C (212°F), incinerate it, or expose its cell
contents to water. Dispose of the battery as required
by local ordinances or regulations. The use of an
incorrect battery can result in ignition or explosion of
the battery.
