2. On the password text box try with three passwords, if all these three passwords are incorrect, you will be blocked with the screen “System Disabled”. And you will get a code to get the backdoor password. Write this code down.

3. Go to another computer with internet connected, open this site: https://bios-pw.org/.

4. Enter the code you get on the System Disable screen and click on Get password.

 

5. You will get a list of passwords. Go to your laptop, restart it and press F1 key to boot to the BIOS entry screen again, and then try with the list of passwords one by one. But you only be able to enter three incorrect passwords before your system is locked. Good luck with you!

2. When disassemble the laptop, find the chip. It is on the back of the motherboard. Grasp the plastic frame and turn the motherboard over, you will see it. As the picture below, the chip is in the red circle.
