How do I unlock Manufacturing Programming Mode

[Ayu2805]

I was getting "Manufacturing Programming Mode is in Unlock mode" and after Locking it I came to know that "Product name, Product number and Serial Number" are empty, I tried chaging it the same way I locked "Manufacturing Programming Mode" but I get an error with reason "Access denied".

Also I have tried unlocking it so that I can chnage those settings but I get the same error.

Thank you in advance

Welcome to the HP support community.

I understand that you are getting "Manufacturing Programming Mode is in Unlock mode" error, I am glad to assist you.

Was there any hardware service or part replacement on the computer? 

Are you able to boot to BIOS by tapping F10 on startup?

Did you run any diagnostics on the computer?

Meanwhile:-

Update the Bios, chipset, and drivers using HP Support Assistant.

Download and run the HP Support Assistant from this Link: Click here

• HPSA will automatically search for all the latest drivers for your Notebook
• Click My devices in the top menu, and then click Updates in the My PC or My notebook pane.
• 
• Click Check for updates and messages to scan for new updates.
• 
• Review the list of updates. Updates with a yellow information icon are recommended. Updates with a blue information icon are optional.
• Click the update name for a description, version number, and file size.
• Select the box next to any updates you want to install, and then click Download and install.

Also, ensure Windows is up to date.

• Select the Start  button, and then go to Settings  > Update & security  > Windows Update , and select Check for updates. If Windows Update says your device is up to date, you have all the updates that are currently available

Let me know how it goes.

Yes the entire motherboard of the laptop was replaced. And I have a fully up to date laptop with all the latest drivers. I have locked the "Manufacturing Programing mode" myself but my issue is that neither BIOS is showing serial number, product name and product number not HPSA. I just need a way to configure BIOS so that these information will be visible. I have techinal knowledge, I just need a way to solve this particular issue so that I can check for serial number from BIOS or HPSA directly instead of finding and checking the whole info from my profile.
