							FRU replacement notices
This section contains notices for removal and replacement.
Read this section carefully before replacing any FRU.
LCD replacement notice
The TFT LCD for the computer contains many thin-film
transistors (TFTs). A small number of missing, discolored,
or lighted dots (on all the time) is characteristic of TFT
LCD technology, but excessive pixel problems can cause
viewing concerns. The LCD should be replaced if the
number of missing, discolored, or lighted dots in any
background is:
vSVGA : 5 or more bright dots, 5 or more dark dots, or a
total of 9 or more bright and dark dots.
vXGA : 8 or more bright dots, 8 or more dark dots, or a
total of 9 or more bright and dark dots.
Screw notices
This computer uses special nylon-coated screws with the
following characteristics:
vThey maintain tight connections.
vThey do not easily come loose, even with shock or
vibration.
vThey need additional force to tighten.
vThey should be used only once.
Do the following when you service this machine:
vKeep the screw kit (P/N 08K6560) in your tool bag.
vAlways use new screws if you are instructed.
vUse a torque screwdriver if you have one.
Loose screws can cause a reliability problem. The IBM
ThinkPad computer addresses this problem with
nylon-coated screws. Tighten screws as follows:
vPlastic to plastic

vLogic card to plastic
Turn an additional180 degreesafter the screw head
touches the surface of the plastic part:
vTorque driver
If you have a torque driver, refer to the″Torque″column
with each step.
vMake sure you use the correct screw, and tighten all
screws firmly to the torque shown in the table if you
have a torque screwdriver.Never use a screw that you
removed. Use a new one. Make sure the screws are
tightened firmly.
System board/LCD/Inverter replacement
notice
Restoring the LCD panel IDThe EEPROM on the inverter stores its supported LCD
type ID code. If you replace a LCD with one of a different
brand or use a new inverter, the ID information in the
inverter EEPROM should be updated.
Follow the steps blew to set the LCD panel ID:
1. Install the ThinkPad CE Utility Diskette and restart the
computer.
2. Select1. LCD Panel ID Utilityfrom the main menu.
22ThinkPad i Series 1200/1300 HMM 
						

							3. Follow the instruction on screen to read current or to
set new LCD Panel ID code.
4. Restart computer : the new LCD should work normally.
Note:When you set a new LCD Panel ID and the new
LCD is not yet enabled (to function), connect an
external CRT to see the program execution process.
CAUTION:
Make sure the new ID code you choose corresponds
with the LCD brand and type. If you write a wrong ID
into inverter, just reboot and re-execute the program
and input the correct ID code.
Note:If LCD cannot display after change ID code, make
sure you write the correct ID code, or try reseating
the LCD FPC cable connectors.
Restoring the Vital Product DataThe EEPROM on the inverter contains vital product data
(VPD). When the computer was manufactured, the
EEPROM on the inverter was loaded with the serial
numbers of the system and all major components. The
EEPROM contains the following serial numbers:
vBIOS build ID (BIOS version number)
vSystem board serial number
vSystem unit serial number
Read/Write theBIOS build IDis the function which is
provided within the ThinkPad CE Utility Diskette to prevent
the failure of writing BIOS build ID into the inverter during
BIOS update.
To Read the BIOS build ID (BIOS version number), do the
following:
1. Install the ThinkPad CE Utility Diskette and restart the
computer.
2. Select3. VPD Data Utilityfrom the main menu.
3. Select1. Read VPD dataand follow the descriptions
on screen to verify the BIOS build ID displayed.
To Write the BIOS build ID (BIOS version number), do the
following:
1. Install the ThinkPad CE Utility Diskette and restart the
computer.
2. Select3. VPD Data Utilityfrom the main menu.
3. Select1. Write VPD datathen select1. Write Build
IDto write the BIOS build ID.

							You must restore thesystem unit serial numberto its
original number when the LCD module or inverter is
replaced.
To restore the system unit serial number, do the following:
1. Install the ThinkPad CE Utility Diskette and restart the
computer.
2. Select3. VPD Data Utilityfrom the main menu.
3. Select1. Read VPD datato verify the system unit
serial number displayed.
4. If it is incorrect, select2. Write VPD dataand then
select2. Write BoxSerial numberto type the correct
serial number on the panel.
Notes:
1. Do not power-off the computer during the restoration
process.
2. The serial number label is attached to the bottom of
the computer.
To restore theplanar serial numberafter you have
replaced the system board, LCD module or LCD inverter,
do the following:
1. Install the ThinkPad CE Utility Diskette and restart the
computer.
2. Select3. VPD Data Utilityfrom the main menu.
3. Select1. Read VPD datato verify the planar serial
number displayed.
4. If it is incorrect, select2. Write VPD dataand then
select2. Write BoxSerial numberto type the correct
serial number on the panel.
Thermal SensorThe system is equipped with sensors to protect against
system overheating. By setting system and processor
thermal thresholds, the system can turn on the cooling fan,
slows sown, stop the CPU or shut down automatically
when temperatures reach the defined threshold
parameters.
System experiencing frequent auto sensor shutdown may
need to reset the thermal sensor threshold and execute
the fan test to ensure the normal operation of the cooling
fan.
Follow the steps below to set thermal threshold:
1. Install the ThinkPad CE Utility Diskette and restart the
computer.
2. Select2. Thermal Sensor Utilityfrom the main menu.
24ThinkPad i Series 1200/1300 HMM 
						

							3. Select1. Read Thermal Settingto view the original
setting or2. Set Default Thermal Settingto restore the
default setting.
UUIDThe Universal Unique Identifier (UUID) is a 128–bit number
uniquely assigned to your computer at production and
stored in the EEPROM of your inverter. The algorithm that
generates the unique number is designed to provide
unique IDs until the year A.D. 3400. Consequently, no tow
computers in the world will 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 CE Utility Diskette and restart the
computer.
2. Select4. UUID Data Utilityfrom the main menu then
make a selection to read or create the UUID data.
A new UUID is created and written. If a valid UUID already
exists, it is not overwritten.

Power button as reset switch
The power button acts as a reset switch when pressed for
more than 4 seconds. This resets the system (regardless
of the microcode status) and forces the power off. Use this
only when power is not completely off or the microcode is
in a hung state.
Running a low-level format
Attention:Make sure the drive address to be formatted
is correct. This procedure erases all information on the
disk.
To format the hard disk, use theFull Erase Hard Driveor
Quick Erase Hard Drivein Utility of the PC-Doctor DOS
program. Refer to“Testing the computer”on page 34.

Passwords
When the power-on password (POP), hard disk password
(HDP), and setup password (SUP) are used, the following
situations may occur:
vIf the POP is the same as the HDP, the POP prompt
appears, but the HDP prompt does not appear.
vIf the POP is not the same as the HDP, both prompts
appear.
Power-on and setup passwordsPower-on and setup password are security features that
are used to protect the system from unauthorized access.
26ThinkPad i Series 1200/1300 HMM 
						

							If power-on or setup password is forgotten, change Bit 4 of
switch SW1 from 1 to 0 to bypass the password.
Removing the power-on/setup passwordIf the customer forgets the power-on or setup password,
set the switch SW1, Bit 4 from 1 to 0 firstly to bypass the
two passwords. Then do the followings to remove the two
passwords:
1. Power on the computer and pressF1to enter the
BIOS Utility menu.
2. The main screen displays as below:

							1. Remove all power sources including the AC adapter
and battery assembly.
2. Remove the RTC battery from the planar a while then
reinstall it.
Attention:The CMOS settings will be restored to default
values if you use this method to remove the power-on or
setup password.
Hard disk passwordThe hard disk password is the security feature that is used
to protect the hard disk data from unauthorized access.
Attention:No overriding capability is provided.
Therefore, if the customer forgets the hard disk password,
the hard disk drive must be replaced.
Power management features
Two power management modes are available in the
computer system to reduce power consumption and to
prolong battery life.
Standby modeWhen in standby mode, the following occurs:
vThe LCD backlight turns off.
