Thermal Sensor

The 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 Maintenance Diskette and restart
the computer.
2. When the IBM logo is displayed, press the "ESC" key
few times until BIOS copyright and diagnostics screen
appears.
3. Select 2. Thermal Sensor Utility from the main menu.
4. Select 1. Read Thermal Settingto view the original
setting or 2. Set Default Thermal Settingto restore the
default setting.
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. These numbers
need to remain the same throughout the life of the
computer.
If you replace the system board, you must restore the
serial number of the system unit to its original value.
Before replacing the system board, save the original serial
number by doing the following:
1. Install the Maintenance Diskette and restart the
computer.
2. When the IBM logo is displayed, press the "ESC" key
few times until BIOS copyright and diagnostics screen
appears.
