When I got my Spectre x360 back in 2016, I booted it into the Windows 10 it came with, played a bit around and then decided to put Linux on it. So I took a backup of all partitions, repartitioned the whole SSD and went on with Linux. Of course, I found a way to install BIOS updates which I regularly did.
Now came the time to sell the machine so I restored my backup to have to original state from back then. To give the buyer a better experience, I wanted to restore it to its factory state using the now restored recovery partition. The recovery process started up just fine and prepared the main partition and started doing things ... until it failed with a strange error message. Trying it over and over again, it always failed at the same step after completely installing the Windows operating system, not very far into installing the OEM software.

you can get to by pressing F2 after switching on the notebook or from
the Startup Menu. The update you download from the hp service page merely
copies the new BIOS files to that partition.

I found three different ways for bypassing the password-check on a Toshiba-notebook. I had no chance to test them, so I

These ones are something different. DELL notebooks save their BIOS password in an EEPROM-chip so it isn't deleted when
you short-circuit the BIOS battery or something like that.
Also there's no jumper/DIP-switch which disables the password. Nevertheless, there are three different ways to get such

In the newer SONY VAIO Notebooks, the BIOS password is no longer stored in the volatile CMOS-area but on an EEPROM.
Jean Delvare has published his results of an analysis of various Sony
Vaio EEPROM dumps on his homepage. There you can see that the BIOS password
is stored encrypted in the first 7 Bytes of the EEPROM and, if no password is set, these Bytes are 00h. So if you
delete the whole chip - like you can do with DELL notebooks - you should get rid of the password.
Unfortunately, this would delete all other informations like e.g. serial number, model name, etc., so that specific
Sony-Applications might cause trouble or even don't accept the notebook as a SONY-device.
