HP Book 800CT manual Logic PCA Board, Programming the Electronic Serial Number

Logic PCA Board

(HP Authorized Service Providers Only)

Electronic Serial Number

The OmniBook 800 (F1360 only) is shipped with an electronic serial number programmed in EEPROM on the Logic PCA Board. This built-in serial number will help MIS managers in tracking assets and software configuration. Serial numbers can also be used for security and in tracking lost or stolen notebooks. The Desktop Management Interface (DMI) TopTools application shipped with the OmniBook can be used to read the serial number locally and across a network.

Programming the Electronic Serial Number

All replacement Logic PCA Boards will arrive with a temporary serial number programmed in EEPROM. The following procedure provides the steps necessary to reprogram the electronic serial number.

1.After installation of the replacement Logic PCA Board and upon reboot, the OmniBook will halt with this prompt:

INVALID ELECTRONIC SERIAL NUMBER PRESS ANY KEY TO CONTINUE

2.After a key is pressed, the OmniBook will continue a normal boot process. The HP Authorized Service Provider must program a valid serial number before the OmniBook can be shipped to the customer.

3.Run the ESN.EXE program located in the c:\omnibook\diag directory.

4.The ESN program will prompt for a valid serial number.

5.Enter the serial number located on the bottom of the OmniBook. The ESN program will burn the serial number into EEPROM.

Overriding an Incorrect Electronic Serial Number

If an incorrect serial number is inadvertently burned into EEPROM, it can be corrected. Perform the following steps:

1.Run the ESN.EXE program located in the c:\omnibook\diag directory.

2.The ESN program will prompt to confirm that the serial number is incorrect. It will then generate a five (5) digit number key.

3.The HP Authorized Service Provider must contact Hewlett-Packard Technical Support at this point.

4.HP Technical Support will ask for a CZ authorization number and the five (5) digit number (from step 2).

5.HP Technical Support will provide a validation key to the HP Authorized Service Provider.

6.Enter the validation key. This will reset the electronic serial number with a temporary number.

7.Follow the above steps in Programming the Electronic Serial Number to enter the correct serial number.

Note, updating the BIOS on the OmniBook will not affect the electronic serial number.
