Re: HP ProBook 450 G3

Any takers on my question? I am curious as to what the process is that was taken for some in the room to solve their issues regarding the HP ProBook 450 G3.

This is the content of the bios chip, you must use a programmer to write/read it.

Re: HP ProBook 450 G3

Thank you. It's working now!

So how did you use this .BIN file to successfully solve this issue? Is it dropped into the original firmware folder provided by HP? Is it apart of the BIOS update? How did you make it work?

I have the same issue. Looking to resolve it.

Hello, please i need help to remove product information not valid on HP 450 g3.

I uploaded the bin file. THANKS.

Re: HP ProBook 450 G3

I appreciate that. If there is a non-invasive solution that doesn't require soldering or replacing the motherboard, I'd like to thoroughly explore. But the tool to generate the SMC bin is available and I have it, It's called WNDMIFIT, which is explained in the pdf attached in my first post. This file/program was downloaded from this forum.

Enough off-topic! WNDMIFIT is not a tool for generating smc.bin files, and there is no other lazy method for unlocking the bios like password encryption from the dump for example or password generator because I expect you to ask that as well. In short "non-invasive solution that doesn't require soldering" does NOT exist for that model.

Re: HP ProBook 450 G3

Thanks for the reply. On the assumption that the SMC method was disabled through bios updates, would it not be true that in some cases, perhaps even my own, where the bios was not updated post 2019, that the SMC solution might indeed work?

Forget about smc.bin man, HP stopped providing it since 2019, no one here has the tool to generate smc.file file regardless of the bios version.

Re: HP ProBook 450 G3

This might be late coming, but have same issue with forgotten bios password, laptop still operable but I can't install a new OS, modify an existing OS, run live cds etc. After researching the topic seems its 1, replacement motherboard, 2. desolder the bios chip, and either direct replacement, or place the old bios in a reader, dump the bios and using hex editor zero out the password and rewrite to bios, resolder into place. I'm wondering has anyone had any success using either DMIFIT and WNDMIFIT to create a smc.bin for this model. Apparently using the bios info, such as Serial number and UUID etc, you create a unique file for your laptop and it should reset the Bios. Attached is a guide HP had for employees on how to use these tools. Any help greatly appreciated
