How to fix Product Information Not Valid


Symptom: your BIOS screens look like this Product Information Not Valid”


  1. First step is to acquire HP’s NbDmiFit tool.
  2. . Version 2.10 is the most current (as of sometime in 2016). I have attached that file to this post in case the original disappears.
  3. Next, become familiar with the documents in the README folder of the NbDmiFit, in particular the flow chart on page 5 of HP Commercial Notebook Step-by-Step Guide – 2.10.pdf
  4. Next find and photograph all of the labels that you can find inside the bottom of your laptop. You are looking for the SKU Number, System Configuration ID, Serial Number, and System Board CT.
  • According to the Step-by-Step Guide, the next step is to create a Windows PE USB disk. I struggled with this for many hours, and while I could create the bootable Windows PE (v10, v8, & v2.1) USBs, I could never successfully run the Wndmifit64.exe application in that environment. HP has a WinPE64-2.10 tool that automates this process, but I failed to replicate it with the Windows ADK. My recommendation is to use an MBR install of Windows 10 rather than the fancy Windows PE method. Note that a GPT/UEFI install of Windows will not work. My solution was to install a blank harddrive into the laptop, and install Windows 10 Pro onto it using a USB drive created with the Windows 10 Download Tool. Note that the BIOS Boot Mode of the laptop must be set to Legacy in order to create a Windows MBR install..
  • Boot into your Windows MBR harddrive, which will likely require you to change the BIOS setting from UEFI Native to Legacy.
  • Once in Windows, run Wndmifit64.exe which is located in the WNDMIFIT folder of the package. You will likely receive an error telling you that the MPM (Manufacturing Programming Mode) is locked.

You will need to unlock the MPM, run Wndmifit64.exe, and then relock the MPM. To unlock the MPM, copy the FSMC.bin file from the WNDMIFIT folder to a Fat32-formatted USB drive. Rename the file to SMC.bin. Plug the USB drive into the laptop with the power off. Hold Windows Key + Arrow UP Key + Arrow Down Key at the same time and power the system on. Release all keys when you see the blue HP logo. You should see a brief message on a white screen saying that the SMC command was handled successfully. This means that the MPM is unlocked, and will remain so for the next 10 power-cycles.

  • Now you need to reset the missing information in the BIOS. To do this, boot back into your Windows MBR harddrive and run Wndmifit64.exe which is located in the WNDMIFIT folder of the package. You should see the Notebook DMI Firmware Interface Tool appear on the screen.

Fill the blanks in with the information that you gathered in Step 3. I would recommend verifying that you have correctly read the Serial Number by performing a search for it on the HP Support site. Note that your laptop may not have numbers for all of these fields, I believe the last two fields are only for laptops manufactured since 2015. Click “Commit Only,” “OK,” and “OK.”



  • The last step is to lock the MPM back up. If you reboot now, you will lose everything that you accomplished in Step 7. Run lockmpm.bat, which is also located in the WNDMIFIT folder.
  • Finally, reboot the system and enter into the BIOS to verify that the System Information has been up restored and restore all of your BIOS settings, including UEFI Native. Remove your Windows MBR harddrive and make all is it previously was. My generated UUID did not match the pre-error UUID, but that doesn’t seem to matter. System Information prior to error:

System information after error was fixed with Wndmifit64:
