Hardware & Technical Bios Psswrd 'forgotten'

So today I was in a café minding my own business. I hear two women saying something about forgotten password. They started commenting on my ice cream. They then discreetly mentioned that I head heard something about a forgotten psswrd. Well they were tracking really loudly. They said something about that it was there 'sons' laptop. The first password. ie the bios had been 'forgotten' . I said casualty 'What they he just entered some random characters at initialisation;' 'Yeah'.

Ok well you going to need to replace that bios chip. They laughed sarcastically said something pcword will sort it . I m like I don't think so. They then ordered what I was eating. So question will the bios chip have to liberally replaced if that password is forgotten. Its gonna cost and insurance would have a minum excess. So much for these millennial tech experts who 'know' everything.
 
I remember Toshiba laptops in the late 90's where you couldn't even replace the BIOS chip to unlock a forgotten BIOS password :D
 
Depends on the laptop model. Some are as easy as pulling the battery out and shorting a jumper or points on the board, some have backdoor recovery methods in the firmware, others may need the nvram or firmware chip physically replaced.
 
If i remember correctly, you can put a Bios on an USB stick and flash it directly from the stick. This will replace everything changed in the currently bios including password.
You just need the correct version and make sure that it is bootable from an usb stick.

True - and some machines, upon detecting a bad checksum after replacement of a secured component - will never power on again.

TPM and stuff like it is way more trouble than it's worth, at least for me.

If I need to protect something, I encrypt it, in software.
