BIOS password is the first thing you should check when buying used laptops, fucking retard

lol, just use windows retard
OP I have said laptop model, you can't clear it by popping the CMOS. You basically have to replace the entire IC hosting the bios for it to be wiped.
Chances are though it's just the Serial Number

Dont replace the IC bro, an external flash would probably do the trick and be much fucking easier.
Jason Murphy
OP has secure boot on
Trying to external flash will fail to boot as it's not paired with the system
Attempting an external flash will need the BIOS PW or just risk bricking the system
The quickest easiest way is swap the mobo or the IC if you can. Still not getting into that drive as it's probably 100% bitlocker'd

from where could I buy a new motherboard for it?

Okay, so with secure boot does it match to a signature on the drive? How does the security measure prevent getting around it via format? Or am I way off base here?

bruh just buy another laptop. is not worth to replace a mobo on a used laptop when you can get another used laptop. Unless you find some deal from someone selling a broken laptop of the same model just for parts
Levi Watson
just realized its probably write protected rom, nvm
Chase Bell
not necessarily, it can be a fun time doing bga and smd swaps on old laptops. If you fuck it up the risk is low, and chips/roms are 10-20 bucks.

Because when it attempts to boot of the external USB it's going to not know the device's signature, it will ask you do disable secure boot FIRST which means you need to get into the bios, without the password you're a bit fucked. OP's only option is swap the motherboard or bios IC.
Give it back, you aren't getting into it during your life time.
Aaron Martin
fair enough buy a new mobo then
Christian Sanders
this is a high end precision laptop from a decade ago. original resale $3-5k depending on options.
it is designed to be difficult to break into

Nah, after TPM 1.0 being fixed you sure as shit aren't going to have some fun with what is obviously someones corporate laptop. Dicking around with TPM 2.0 essentially bricks itself, and depending how bitlocker was implemented you're not going to use the drive.
It's a fucking brick for OP unless he can replace the motherboard, the drive is probably trash too depending on what settings they pulled.
James Butler
not for me, buying a new one would be the best option
