Looking at a used Lenovo laptop and the seller has listed it as having a "BIOS lock" but that "does not affect performance at all"
What does that mean?
Is a BIOS lock similar to the existence of a firmware password and not knowing what it is on the Mac side of things?
Curious if a BIOS locked PC is still useable, software upgradeable, able to log in to Windows, etc.
Thanks

Thanks for those links
Assuming one cannot "unlock" the BIOS despite attempting the steps outlined in those links, what does a locked BIOS prevent one from doing? Is it a deal-breaker?
Thanks

a locked BIOS may prevent you from changing the boot drive, or making other settings such as power management, default num lock ON or OFF, etc.
I would not buy a computer with locked BIOS unless I knew it was set to the default settings, or if there were an way to defeat it.

Bios lock is security protection for a computer.
It can prevent someone from booting from other than the internal drive, restrict the ability to use a flash drive, or basically changing the OS etc., to make it tamper resistant or having your data stolen. It might even restrict adding software such as a key logger, etc.
Obviously, you'll need the password.
If Bios-Lock is a feature on the PC you're looking at/for, no worries. I'm sure it can be toggled on or off by someone with Admin privileges.
If someone is selling you a computer, 'cheap' because it's bios-locked, you'll want to look elsewhere.

It's borderline useless, it could be a good deal if you just want to buy it for parts (hard drive, screen, keyboard, RAM).

I’ve bought a couple of off lease bios locked Dells in the past. I knew they were easy to defeat (after googling) and one seller even gave me the password after the sale. If the company is reputable I wouldn’t hesitate. Sometimes the IT department puts the bios lock to prevent booting off other drives as mentioned.

From a source like a legitimate seller of used laptops coming off institutional use who can provide the PW to unlock the BIOS, I would not have a problem buying such a laptop. But a listing such as mentioned in the OP that stated things like "does not affect performance at all" , sounds just a little fishy. Best case is you get a computer that can be unlocked, worst is that it was stolen or otherwise removed improperly from an organization and that causes issues later.
