UUID (System Information Page): It is a unique number of your computer. When your computers boot Press “ESC” and then F1 to get into System information Page. This may vary, at the time of support, you will be guided how you can get on this page according to your computer brand.
Authorization Latter:
A hand-written letter to the support team that you wish to seek help to reset the password.
Step 2. Send them required information.
Once you make a request by either chat or phone support, you might ask to provide those 4 files.
When you send all the required documents, the support team will transfer your case to next department.
After some time they will send you an email with 2 files mostly.
Step 3. The main process.
The one will be an SMC BIN file and second is a document to tell you how to perform the process to reset your Admin BIOS password. The Bin file is actually manually generated and will only be valid for 7 days from creation.
If you have an HP laptop you will find a disk partition named “HP Tools” you need to move both files to that drive as well as copying both to a USB device.
Important: You need to manually rename the SMC.BIN.bin file to only SMC.bin (where .bin is s file extension so do not get confused.)
How to Reset BIOS Password using SMC.bin
This process may be different for your computer and model. The section is as if we are resetting Bios admin password of an HP Probook.
Step A. Turn off your laptop or computer.
Plug the USB (Pen Drive) to a 2.0 USB port (In case of an HP laptop).
Step B. Press “WINDOWS + UP Arrow + Down Arrow“ Key until you hear the sound of your FAN (Your PC’s fan will run at 100% speed, so you’ll notice probably.)
Release the keys and press F10 when computer boots. You’ll see a message that “SMC command successfully accepted.”
Step C. Don’t just turn off your PC and boot windows. Instead, press F10 at next boot, and directly get into BIOS where you can change the BIOS password. Even if you did not set a BIOS password, you would not be prompted to enter any password in future. It is just you need to enter into BIOS just after the SMC command accepted.

This workaround works fine with old desktop computers. Using the Jumper all CMOS associated information will be erased, so is the BIOS password. As there are thousands of motherboard models, you need to find the jumper location, most of the time you can figure this out by either looking your motherboard manual or just look for any of these labels ‘CLR/ Clear’.
Once you find the Jumper you’ll see 3 Pins; the center pin will be attached to either the left or the right pin. To clear the BIOS password, you just need to just attach the center pin to the opposite pin. (eg. ! !_! → !_! !) Now wait for a few minutes and plug the jumper again to its original position (eg. !_! ! → ! !_!)
Note: When doing this ensure the power to the computer remains off, take precaution when doing this.
