How Do I Reset My Toshiba Laptop BIOS?BIOS passwords offer an extra level of security for your Toshiba Laptop computer by requiring users to enter a password before they can enter the setup programs or start the operating system. If the Bios passwords are lost then it can be a headache, because it is very difficult to enter into the computer. Here are some tips that will provide you with some tips for circumventing unknown BIOS passwords so that you will be able to use the computer system once again. An introduction to BIOS passwords: BIOS passwords are primarily of two types that can be used to protect a computer system. The first type requires the user to enter a password before being granted access to the computer's setup programs. Many system administrators will use these types of passwords to prevent their users from modifying the system configuration. The second type of BIOS security requires the user to enter a password before the operating system is started. This type of password is used to prevent an unauthorized user from accessing the system. When such a security measure has been implemented, users will be unable to boot the system in any manner unless they have the password. Backdoor passwords The Bios password can be unlocked by using the BIOS manufacturer's "backdoor password." These passwords are hard coded into the BIOS by the manufacturer and will override any user-created password. Although it sounds easy, you must know who made the BIOS, what BIOS version has been installed in the system, and what backdoor password was used for the BIOS. Contact the BIOS manufacturer if you want to learn about the backdoor BIOS password for a system. Resetting the CMOS using motherboard jumpers A couple of motherboard manufacturers like Toshiba Laptops provide jumpers that allow technicians to easily reset the CMOS values to their default settings. What this program will do is that it will eliminate a user-created BIOS password and set the value of the Use BIOS Password field to No. Generally, to reset the CMOS values, you would turn the system off, change the jumper settings according to the motherboard's documentation, and turn the system back on. You will begin a journey to the BIOS setup program, where you can change the CMOS configuration as you see fit. You should turn off your system after you are out of the BIOS, return the jumpers to their original setting and then you should turn the system off, and finally power the computer on again. The system will boot using the new configuration data, and you will no longer be prompted for a BIOS password. If you elect to reset the CMOS values to erase the BIOS password, you will lose all information that was previously stored in CMOS so back it by the CMOSSAVE program, you can easily restore them. Make sure that your backup copy does not require the use of the BIOS password otherwise you will be where you started. |
