Hi Terry,
Please check the steps below for updating Service Tag on the system. These steps would only work if the new motherboard supports this option:
Once the system board is replaced, turn on the system and press <F2> to enter the BIOS.
| |||
| 3. | The BIOS then boots into the Service Tag screen.
| ||
| 4. | Press <Enter> to start the Service Tag scroll bar.
| ||
| 5. | Use the arrow keys to enter the Service Tag.
| ||
| 6. | When the Service Tag has been entered correctly, press <Enter>.
| ||
| 7. | Press <Enter> to save the new Service Tag entry.
| ||
| 8. | Press <Esc>.
| ||
| 9. | Use the arrow keys to highlight the Save/Exit button and then press <Enter>.
| ||
| 10. | The system reboots. |
If you have any further queries, please feel free to contact us.
Thanks and Regards
Sandeep P
