I have a toshiba and would like to know howto restart it to factory settings, some one added a password and now I cannot do anything with my own computer.

Do you have a recovery CD? Or is there a recovery partition?

To access the Toshiba recovery partition, power off the laptop. Hold down the 0 (zero) key and turn the laptop on. Keep holding down the zero key until the TOSHIBA logo appears, where you should start tapping the zero key repeatedly. Stop if the unit beeps or when the TOSHIBA logo disappears. The screen should flash ** HDD RECOVERY MODE ** for a split second, then load the Toshiba recovery program right from the hard drive.

Note that this erases all data, and reloads all factory default software. Be sure to back up all your important personal data beforehand!

Hope this helps :)
