Resolve HP Z2 Tower G4 BIOS Warning: A Step-by-Step Guide

Select Language:

If you’ve recently bought a used PC, especially one with an HP motherboard, you might run into some frustrating issues—one of which could be a BIOS warning like “Product information not valid.” This can leave you feeling stuck, especially if you can’t find the required information to resolve it. But don’t worry! Here’s a straightforward guide to get your PC running smoothly again.

The Problem

When the BIOS shows warnings about missing or invalid product information, it’s usually due to the motherboard not having the correct details programmed into it. In your case, the error is indicating that the system board feature byte, build ID, and serial number are missing or invalid. This can happen if stickers containing important information have been removed or if the motherboard was replaced.

Step-by-Step Solution

1. Look for Available Information:
   Go through the PC and gather all the available details from stickers and labels. You’ve already found a few numbers from the stickers, like:

   • PJDFA0ECYDJ1L3 (possibly the serial number)
   • Other SP numbers and revisions

2. Utilize the HP BIOS Tool:
   Review the information provided by the HP BIOS tool. You’ve got some key details that will help you, including:

   • Product Number: 2YW27AV
   • System Board CT Number: PJDFA0ECYDJ1L3
   • Exact Model: HP Z2 Tower G4 Workstation

3. Enter Missing Information:
   When you see the warning at startup, press ‘Y’ to access the screen where you can manually input any missing information. Use the details you previously gathered.

4. Contact HP Support:
   Since the information you have isn’t matching up in HP’s database, your next step should be to reach out to HP’s customer support. They can guide you through the process of obtaining the correct BIOS settings or may even provide the necessary firmware updates.

5. Update BIOS Firmware:
   Ensure your BIOS is up to date. If there’s a more current version available, installing it may resolve any compatibility issues. Check the HP support website for your specific model and follow the instructions provided for updating.

6. Reboot and Test:
   After inputting the information and possibly updating the BIOS, restart your computer. If the BIOS warning no longer appears, congratulations! You’ve solved the issue.

7. Document Everything:
   Make a note of all the information you’ve gathered and any updates you’ve made for future reference. This will come in handy if you encounter similar issues down the road.

By following these steps, you can address the BIOS warning and move forward with your workstation. If you still encounter issues, consider consulting a professional technician for further assistance. Remember, troubleshooting can be a process, but with patience and persistence, you’ll find the right solution.
