Note: If the LCD has no display after changing the ID
code, make sure you write the correct ID code or
try reconnecting the LCD FPC cable connectors.
Setting the Thermal Sensor:
The system is
equipped with sensors to protect against system over-
heating. By setting the system and processor thermal
thresholds, the system can turn on the cooling Fan ASM or
shut down automatically when the temperature reaches the
defined threshold parameters.
System experiencing frequent auto sensor shutdown may
need to reset the thermal sensor threshold.
Follow the steps below to set the thermal threshold:
1. Boot from the Maintenance Program Diskette.
2. Select Thermal Sensor Utility from PC DOS 7.0
Startup menu.
3. Follow the instructions on the screen to set the
thresholds.
Writing the VPD Data:
The EEPROM on the
system board contains the vital product data (VPD) — that
is, a system unit serial number and a system board serial
number. When you replace the system board, restore the
system unit serial number using the VPD Data Utility. The
serial number label is attached to the computer.
Edit the batch file in the diskette A:\active.bat
