How to Reset the BIOS Password for Laptops
You can lock the BIOS with a password and stop any unauthorized entry into your computer. This low-level security obstacle can stop anyone with a bootable Windows flash drive or a Linux Live CD a way around the Windows login password.
But what if you set a BIOS password and can’t remember what it was?
A BIOS password can be easily reset by opening the device and removing the CMOS battery. It cuts off the power to the BIOS and everything in the memory gets erased. It is easy on a desktop computer but a difficult job in many ultrabooks and tablets.
Thankfully, there is an easier way which is helpful for basic users.
The method takes advantage of the backdoors built by manufacturers. The default passwords for specific vendors have been available for some time. A blogger called Dogbert has also developed a website that calculates the vendor password.
Here's How:
1. Switch on your PC and enter a wrong password three or more times.
2. A message will display an alert that says your system is disabled or the password failed.
3. The message will also include a number. Note the number as it will help you generate the BIOS backdoor password.
4. Open the BIOS Master Password Generator page on another computer or smartphone.
5. Enter the number you saw on the BIOS screen. Click the Get password button to see a list of computer models and passwords. Try the password that is for a machine closest to yours.
6. Reboot your machine to the BIOS password screen and enter the password.
You can always call up customer support and give them the number that came up on the alert screen.
