Tips to Keep in Mind While Setting Up Toshiba® A135 BIOS Password
When a computer starts software is loaded in the memory of the CPU. The Basic Input/Output System software intermediates the connection between the keyboard, processor, RAM memory and other components in the laptop. This is where BIOS interact between the CPU and the peripherals of the computer to have a smooth start up. To protect the BIOS settings, you should set a password. To get rid of the old password, power-off the laptop. Through this method the password may reset to the default setting. Otherwise, use a BIOS password crack software program for recovering the BIOS. Recovering the factory settings erases the hard drive and the information cannot be recovered unless you back up your data on another disk drive or the portable hard drive first.

After, this reinstall the battery and turn on the PC. Continuously press the appropriate "F" key as you are turning it on to enter the BIOS. This key is usually "F2," "DEL," or "F12," but is prompted on the black startup screen. If you do not get into the BIOS, and Windows started loading, restart the computer and try again.
