Any ideas on how to get this rectified would be appreciated as these laptops are not cheap, and having a BIOS password is not ideal!

Thanks everyone for your suggestions so far! :) I no longer have this HP Zbook G2, but hopefully these steps will go some way to helping other people that have this issue!

@ruggb - HP’s BIOS passwords are stored in non volatile memory that isn’t cleared once you’ve reset the BIOS battery (yes I did check this). HP themselves are useless and no longer supply the files required to reset the BIOS. They recommend an entire new motherboard, which obviously isn’t going to happen.

Now if you have the correct tools for the job, you can use a hot air/reflow station to remove the BIOS chips from the motherboard, and use a programmer to re-program the BIOS, but I don’t have the equipment to do this at present.

@sunflowerthomas removing the CMOS battery didn’t work for me. I tried that, to no avail.

Guy Fawkes - I would have tried this if I still had the laptop. Unfortunately I don’t have the laptop anymore, and I would alos have to load two operating systems onto the machine (windows 7 & 10). Having a M.2 adapter definitely helps (but I didn’t have one when I had the laptop). It might work - I’ll bear this in mind if I ever come across a BIOS locked laptop in the future. (The laptop still booted, but I couldn’t change the boot order, or boot off any external device.)
