Hey all,\n\nI have 2 Latitude D400's that were purchased new back in 2004. The specs on\nthe machines are identical to each other.\n\nOne of them has a badly beat up casing, the other has a bad motherboard.\nSince both of these machines are out of warranty I figured that I would just\nswitch the the case around so that the good motherboard was in the good case\netc.\n\nThe mission is a success! I now have a working D400 with a pristine\ncondition case. The only problem is that the service tag on the bottom of\nthe laptop casing, no longer matches what is shown in the BIOS. I have tried\nto change the service tag but keep getting errors when trying to do so.\n\nWhen I run the asset.exe command, I get the following...\n\na:\ asset /s xxxxxxx\nASSET -\- Version 2.01 (C) Copyright 1993 - 2000 Dell Computer Corp\nAbout to change the Service Tag. Are you sure? [y,n]\n(I enter y)\nBEEP\nError: Cannot change the Service Tag.\nPlease ensure the tag is in a correct format, and the SETUP password\nis disabled.\n\nThere is no BIOS password and the service tag i am trying to enter is in the\ncorrect format. I have even tried the asset /s /d to completely delete the\nservice tag but I get the same error?\n\nAnybody come across this before?
