Solution - How to Change Dell Service Tag on any DeLL Laptop Model.

1. Download the Dell Latitude and Inspirion BIOS Upgrade and Diagnostics CD

I found it here:

2. Unzip the file and burn the ISO to a cd

Unzip the file using winzip or 7-zip and you will end up with a file called Dell Portable Bios and Diags Rev A34.iso. Use Nero, Roxio, Image Burn (whatever program you might have) to burn the image to a cd.

3. Boot from the cd

Stick the cd in the laptop and turn it on. Hit F12 at the DELL logo and you will get the Preparing one-time boot menu ..... choose CD/DVD/CD-RW Drive.

4. Choose a selection
The cd will boot up and give you 4 options to select from. Choose option 3. Run the Service Tag Utility

5.Erase the current service tag

It will come up and warn you that choosing yes will erase the asset, owner and service tag. Luckily we don't use either of the first two fields so I just choose yes and hit enter. If you do use asset and owner info in the BIOS I suggest you write them down first.

6. Enter in the correct Service Tag

It will then erase the incorrect service tag and ask you to enter a new one. Enter in the correct one and hit enter.

7. Verify the Service Tag

It will ask you to verify the service tag. Enter in the correct service tag and hit enter again.

8. Are you Sure?
It will ask you if you are sure you want to change the service tag. Choose yes

9. Operation successful

It should tell you it was successful. Remove the cd and reboot. Your service tag is now changed. I tried rescanning the laptop in spiceworks but alot of the info was still messed up so I deleted and scanned the network... from there everything was fine.
