Hi Angelina,
You have to pull-out the cmos battery of your laptop to erase the password. This is like the battery watch inside. Re-insert it after 5-10 mins then power up the unit.

How to Bypass BIOS Passwords


BIOS passwords can add an extra layer of security for desktop and laptop computers. They are used to either prevent a user from changing the BIOS settings or to prevent the PC from booting without a password. Unfortunately, BIOS passwords can also be a liability if a user forgets their password, or changes the password to intentionally lock out the corporate IT department. Sending the unit back to the manufacturer to have the BIOS reset can be expensive and is usually not covered in the warranty. Never fear, all is not lost. There are a few known backdoors and other tricks of the trade that can be used to bypass or reset the BIOS v Before attempting to bypass the BIOS password on a computer, please take a minute to contact the hardware manufacturer support staff directly and ask for their recommended methods of bypassing the BIOS security. In the event the manufacturer cannot (or will not) help you, there are a number of methods that can be used to bypass or reset the BIOS password yourself. They include:
Using a manufacturers backdoor password to access the BIOS
Use password cracking software
Reset the CMOS using the jumpers or solder beads.
Removing the CMOS battery for at least 10 minutes
Overloading the keyboard buffer
Using a professional service
Please remember that most BIOS passwords do not protect the hard drive, so if you need to recover the data, simply remove the hard drive and install it in an identical system, or configure it as a slave drive in an existing system. The exception to this are laptops, especially IBM Thinkpads, which silently lock the hard drive if the supervisor password is enabled. If the supervisor password is reset without resetting the and hard drive as well, you will be unable to access the data on the drive.
----------------------------------------------------------------------------------------------------------- Backdoor passwords
Many BIOS manufacturers have provided backdoor passwords that can be used to access the BIOS setup in the event you have lost your password. These passwords are case sensitive, so you may wish to try a variety of combinations. Keep in mind that the key associated to "_" in the US keyboard corresponds to "?" in some European keyboards. Laptops typically have better BIOS security than desktop systems, and we are not aware of any backdoor passwords that will work with name brand laptops.
WARNING: Some BIOS configurations will lock you out of the system completely if you type in an incorrect password more than 3 times. Read your manufacturers documentation for the BIOS setting before you begin typing in passwords

Key Disk for Toshiba laptops Some Toshiba notebooks allow to bypass BIOS by inserting a "key-disk" in the floppy disk drive while booting. To create a Toshiba Keydisk, take a 720Kb or 1.44Mb floppy disk, format it (if it's not formatted yet), then use a hex editor such as Hex Workshop to change the first fwe bytes of the second sector (the one after the boot sector) and set them to 4B 45 59 00 00 (note that the first three bytes are the ASCII for "KEY" :) followed by two zeroes). Once you have created the key disk put it into the notebook's drive and turn it on, then push the reset button and when asked for password, press Enter. You will be asked to Set Password again. Press Y and Enter. You'll enter the BIOS configuration where you can set a new password. .

Can you find bios password in recovery disks


No. The BIOS password is established in the BIOS only. The OS has not even begun to load at the time the BIOS password is required, In desktops PCs the BIOS password can be circumvented by using the BIOS jumper to reset the BIOS, but laptops are not so forgiving. Manufacturers made it difficult to bypass the passwords to discourage theft. Users are well advised to write down their laptop passwords and put them in a safe place away from the machine in case such situations arise.

Procedure for setting a passcode for laptop so that nobody can open it.


To prevent and secure anyone from accessing your laptop, you can place a Power On Password on your laptop. This Power On Password comes up as soon as you switch on your laptop and won't allow access any access unless the correct password is entered. There are no backdoor passwords to bypass the Power On password to get into your laptop.
You can also place a hard disk password on your laptop and this will prevent anyone from accessing the data on your hard disk, even if they install the hard disk into another computer. There are no backdoor password to bypass the hard disk password.
You may also enable a BIOS password to prevent anyone from changing your BIOS settings.
These passwords are configured in the laptop's BIOS under Security settings.
Once you create these passwords, I suggest you write down these passwords and place them in a safe place should you need need them.

It keep asking for a password as soon i turn it on


There is only ONE FREE way, and that is to make and use a Key Disk for Toshiba laptops.
Some Toshiba notebooks allow to bypass BIOS by inserting a "key-disk" in the floppy disk drive while booting. To create a Toshiba Keydisk, take a 720Kb or 1.44Mb floppy disk, format it (if it's not formatted yet), then use a hex editor such as Hex Workshop to change the first fwe bytes of the second sector (the one after the boot sector) and set them to 4B 45 59 00 00 (note that the first three bytes are the ASCII for "KEY" :) followed by two zeroes). Once you have created the key disk put it into the notebook's drive and turn it on, then push the reset button and when asked for password, press Enter. You will be asked to Set Password again. Press Y and Enter. You'll enter the BIOS configuration where you can set a new password. .
Or one can take it to an authorised service center, and for a price, and with proof of ownership, they will unlock your unit for you
