Hello! I want to change the service tag on my Dell vostro 200 back to the original tag,it must have been changed by the previous owner. I have used both asset.com and svctag.exe but these programs just tell me that they don´t support the bios modell. I have talked to Dell support but they just say that the service tag can´t be changed,Dell support sucks. I have changed the service tag on other Dell computers before but never on a Vostro. Does somebody please have any clue on how to fix this?? Please help me!! Brg Madzter
