IBM Thinkpad R30 R31 Manual

							Note:If LCD cannot display after change ID code, make
sure you write the correct ID code, or try reseating
the LCD coaxtial cable connectors.
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
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.
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 24RF08. 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. Select3. 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, selectUtility, and then use the
Full Erase Hard DriveorQuick Erase Hard Drivein
Utility of the PC-Doctor for DOS program. Refer to“Testing

Passwords
When the power-on password (POP), hard disk password
(HDP), and supervisor password (SVP) 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.
vWhen SVP is set, POST should invoke BIOS setup
without erasing POP. Before entering BIOS setup SVP
26ThinkPad R30/R31 HMM 
						

							will be prompted. If correct SVP is entered, POST enters
BIOS setup without erasing POP. To boot up the system
user should override POP by SVP at the password
sub-menu.
vWhen SVP is not set, POST erase the POP and then
boots up the system.
Power-on passwordsPower-on password is a security feature that is used to
protect the system from unauthorized access. If power-on
password is forgotten, follow the procedure described in″
Removing the Power-on password″.
Supervisor passwordA supervisor password (SVP) protects the system
information stored in the IBM BIOS Setup Utility . The SVP
must be entered in order to access the IBM BIOS Setup
Utility and make changes to system configuration settings.
Attention:If the SVP has been forgotten and cannot be
made available to the servicer, there is no service
procedure to reset the password. The system board must
be replaced for a scheduled fee.
Removing the power-on passwordIf the customer forgets the power-on password, follow this
procedure to erase POP if SVP is not set:
1. Turn off the system.
2. Set DIP SW“Switch Locations”on page 193.
3. Turn on the system, and confirm the system starts
without prompting for Power-on password.
4. Turn off the system.
5. Set DIP SW“Switch Locations”on page 193.
If SVP is set, do the followings to erase POP:
1. Power on the computer and pressF1to enter the
BIOS Utility menu.
2. Enter correct SVP (Supervisor password) at the
password prompt.

							Checkout guide
Use the following procedure as a guide for computer
problems.
Note:The diagnostic tests are intended to test only IBM
products. Non-IBM products, prototype cards, or
modified options can give false errors and invalid
system responses.
1. Obtain the failing symptoms in as much detail as
possible.
2. Verify the symptoms by attempting to recreate the
failure by running the diagnostic test or by repeating
the same operation.
Testing the computer
The ThinkPad computer has a test program called
PC-Doctor DOS (hereafter calledPC-Doctor). You can
detect errors by running the diagnostics test of PC-Doctor.
This section is an overview on detecting the problem.
Refer to“Product overview”on page 102 for details that
depend on model-unique functions.
To run the test, do the following:
Note:In the following procedure, you can select an item
not only with the arrow keys, but also with the
TrackPoint. Instead of pressingEnter, you also can
click the left click button.
1. Insert the PC-Doctor DOS Disk into the diskette drive;
then power on the computer.
If the computer cannot be powered on, go to“Power
systems checkout”on page 36 and check the power
sources.
If an error code appears, go to“Symptom-to-FRU
Index”on page 40.
The PC-Doctor main panel appears.
2. SelectDiagnosticswith the arrow keys, and press
Enter.
A pull-down menu appears:
Note:The pull-down menu differs depending on the
model.
3. Run the applicable function test.
4. Follow the instructions on the screen. If there is a
problem, PC-Doctor shows some messages.
5. Reseat the cable or connector of the detected FRU
and run the test again.
