By removing all power to the board, you force it to forget the password. This works on all models of laptop I have found. The only differences are where the Bios/CMOS battery is located. Some are very accessible, located easily on back, other require removing the keyboards, etc.

Some BIOS manufacturers or the laptop maker put a backdoor password in BIOS and will always work regardless of what password you have set in the BIOS. It is a master password which is used for testing and troubleshooting purposes, or in the event you lock yourself out of your own laptop.

If you have a recent Dell laptop, the only cure is to find someone to install a new BIOS chip, or have Dell replace the motherboard if it is under warranty. Just went through this with a client who has a 2 year old +- Dell Inspiron 3542, and that is the Gospel from Dell Tech support. No jumpers on the mobo, no magical master password from Dell. Dell removed the jumper from their laptops in 2004, but the encryption has gotten stronger and stronger to the point where it would take the NSA to crack it, because even Dell has a very low success rate. We never got to the point of discussing if those fixes would help if the PW was also set on the hard drive, but I suspect that in that case, you are totally SOL. If you do set either of those passwords, for your own sake do regular backups of your important files to an external drive.
Hi, Only my Camera on my lap top is password protected in the BIOS. Now that I have to work from home, I need the camera for tele conferences. I have forgotten the password. I did this to protect my children when using my laptop. It is a Dell
So most BIOS manufacturers have a fail-safe that will show what is called a checksum of the password once you enter the incorrect password more than 3 times. For example, I have an Acer laptop at home and I went ahead and set a BIOS password and then entered the incorrect password three times.
"I have a laptop that (was given to me / I bought on ebay / I forgot the password for). I can't (start it / upgrade the BIOS / change BIOS settings) because it's asking for a BIOS password. I don't know what the password is. What can I do to override the BIOS password?"
Removing the BIOS backup battery seldom works on a modern laptop. Indeed, every search for "BIOS password removal" turns up "Remove the BIOS backup battery." About twelve years (at this writing in 2018) ago this did work on some machines.
If you can prove to the manufacturer that you are the registered owner of the laptop, they can sometimes issue an override password. This is true for (a) older systems (b) without the TPM (see below) or (c) under very specific conditions where the BIOS issues a "challenge hash" in response to repeated access failures.
On some older models (T500 and W5xx series, ca. 2012) it is reported possible to disassemble the laptop, reassemble it "naked" and set a new supervisor password by creative rewiring and clever timing. This is useful only for very experienced technicians; a slight slip can destroy the motherboard.
