HP Motherboard Tattoo DMI Utility: What Is It and How to Use It

If you have ever replaced a motherboard on an HP laptop or desktop, you may have encountered a problem where the system does not recognize the new hardware and displays an error message such as "Product Information Not Valid" or "Invalid Electronic Serial Number". This is because HP uses a special code called a "tattoo" or a "DMI" (Desktop Management Interface) to link the system board with the BIOS and the operating system. The tattoo contains information such as the product name, serial number, SKU, family, and CT number. Without this tattoo, the system will not function properly and may refuse to boot or activate Windows.

To solve this problem, you need to use a special utility provided by HP to write the correct tattoo information to the new motherboard. This utility is called the HP Motherboard Tattoo DMI Utility, and it is only available for HP authorized partners and service providers. The utility is not publicly accessible and requires a valid HP partner login to download. The utility is also updated every year to support new models, so you need to make sure you have the latest version that matches your system.

How to Use the HP Motherboard Tattoo DMI Utility

To use the HP Motherboard Tattoo DMI Utility, you need to follow these steps:

Download the utility from the HP partner portal and extract it to a USB flash drive. The utility is usually named HPBQxxx.EXE, where xxx is a number that indicates the version.

Boot your system from the USB flash drive. You may need to change the boot order in the BIOS settings or press a key such as F9 or F12 to access the boot menu.

Once you see a DOS prompt, run the utility by typing its name and pressing Enter. For example, if the utility is named HPBQ193.EXE, type HPBQ193 and press Enter.

The utility will scan your system and display the current tattoo information. If you see any missing or invalid data, you need to enter the correct values for each field. You can find these values on a sticker on the old motherboard or on the service label at the bottom of your laptop. Here are some examples of what each field means:

Serial Number: enter the serial number written at the bottom of the laptop (S/N)

Notebook Model: enter the model of your notebook (e.g. HP ProBook 450 G2)

GUID Number: you can leave it unchanged

UUID Number: select "1" and it will be generated automatically

CTO Localization Code: enter the code that indicates the country and language of your system (e.g. US for United States)

Asset Tag: enter any custom label that you want to assign to your system (e.g. ABCD1234)

MotherBoard#: enter the part number of your new motherboard (e.g. 123456-001)

H/W Config.#: enter the hardware configuration code of your system (e.g. 0001)

Once all the strings are entered, it will prompt you to write the data or to quit. Choose "Y" to write the data and wait for the utility to complete and return to the DOS prompt.

Reboot your system and check if the error message is gone. If everything is OK, you have successfully tattooed your new motherboard.

Conclusion

The HP Motherboard Tattoo DMI Utility is a useful tool for repairing or replacing an HP system board. However, it is not easy to obtain and use, and it requires some technical knowledge and skills. If you are not confident or experienced enough to perform this task, it is recommended that you contact an HP authorized service provider or partner for assistance.
