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.
