from the IBM website.
Setting the LCD Panel ID
There is an EEPROM in the inverter which stores its sup-
ported 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 below to set the LCD Panel ID:
1. Boot from the Utility Program Diskette.
2. Select LCD Panel ID Utility from PC DOS 7.0
Startup Menu.
3. Follow the instructions on the screen to read the
current or to set a new LCD Panel ID code.
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.
Attention: Make sure the new ID code you choose
corresponds to the LCD brand and type. If you write a
wrong ID into the inverter, just reboot and re-execute
the program and input the correct ID code.
4. Restart the computer — the new LCD should work
normally.
Note: If the LCD cannot 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 overheating. By setting the system and processor
thermal thresholds, the system can turn on the cooling Fan
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 and execute
the Fan test to ensure the normal operation of the cooling
Fan (refer to “Fan Checkout” on page 28).
Follow the steps below to set the thermal threshold:
1. Boot from the Utility Program Diskette.
2. Select Thermal Sensor Utility from PC DOS 7.0
Startup menu, then press F4.
