You'll need a special tool that only Toshiba has. I believe you can get yours cleared for FREE if you tell them that all of a sudden out of nowhere you have a bios password. Stick to that story because they've already admitted to the problem with many of their laptops. You'll have to find an authorized Toshiba repair center to take care of it for you. Otherwise I believe they charge around $100 to clear it.

Don't bother to try the cmos battery trick, it doesn't work on your model. The password is stored on an onboard chip.

remove the power cable, batter and the cmos battery from the computer, wait a couple of minutes and reassemble. The bios with the password will be reset.
