Method 1 – Remove Battery

For desktop user, open up your computer casing and look for the battery. Remove the battery for approximately 5 minutes (maybe longer, depending on the motherboard) and slot it back. By removing the battery and deprive the motherboard’s flash memory of power supply, you are essentially resetting the settings back to default when the existing data in BIOS are cleared.

    This information is intended for experienced users. It is not intended for basic users, hackers, or computer thieves. Please do not try any of following procedures if you are not familiar with computer hardware. I’ll not be responsible for the use or misuse of this information, including personal injury, loss of data or hardware damage. So use it at your own risk.

    A. By Using the Motherboard Jumper:

    In most motherboards CMOS battery is soldered, which makes it difficult to remove the battery. In this case we use another method.

    Almost all motherboards contain a jumper that can clear all CMOS settings along with the BIOS password. The location of this jumper varies depending upon the motherboard brand. You should read your motherboard manual to check its location. If you don’t have the manual then look for the jumpers near the CMOS battery. Most of the manufacturer label the jumper as CLR, CLEAR, CLEAR CMOS, etc.

    When you find the jumper, look carefully. There will be 3 pins and the jumper will be joining the center pin to either left or right pin. What you need to do, is remove the jumper and join the center pin to the opposite pin. e.g. if the jumper joins center pin to left pin, then remove it and join center pin to right pin. Now wait for a few seconds and then again remove the jumper and join the center pin to left pin.

    Make sure to turn the PC off before opening the cabinet and resetting the jumper.

    B. By Using Software:

    I have found that BIOS/CMOS Password Recovery Tool is the most effective.:
    BIOS/CMOS Password Recovery Tool is a program that works instantly to remove any lost or forgotten BIOS/CMOS password. Simply boot your PC to DOS and execute the program, and get access to forgotten BIOS/CMOS passwords in just seconds

            Have you tried contacting Toshiba? Usually they have a master key if the following master key doesn’t work. Another method is to remove the laptop battery and the internal tiny battery. This will reset the Bios and remove the password, but it might damage the laptop or void the warranty.

      If the following 2 methods, especially the battery removal method (the small round battery as shown in the photo, not the big removable battery in laptops) does not work, you may have to refer to your manufacturer.

      Have you tried removing the laptop battery? the tiny battery inside the laptop? removing the round tiny battery for a few minutes will reset your BIOS with no password. Remember, your warranty voids if you open your laptop. And if you have important data, make sure the person that handles your laptop perform the task in front of you.

      I don’t think you can ‘buy’, you’ll have to send to Asus service center. Perhaps they have a ‘master key’

      in your BIOS settings, choose to remove or reset the BIOS password. When given a choice, leave the password field empty and save. this will remove the bios password
