You can use this plug to remove or clear the BIOS password from older Toshiba laptops. I tested the plug and it successfully cleared the BIOS password from Toshiba Satellite 1415, Satellite 1800 and Satellite Pro 6100. Using the plug you should be able to remove a BIOS password from most Pentium III Toshiba laptops and from some Pentium IV laptops. To make a password removal tool you need a DB25 plug from a parallel printer cable (cable with a plug that you can take apart), a solder gun and 30-40 minutes of your time.

Cut a DB25 connector off an old parallel printer cable and remove screws to disassemble the plug. The wires should be long enough to strip the ends and solder them.
All pins on the connector are marked from 1 to 25 and you should connect and solder together the wires from the following pins:
| 1+5+10 | 2+11 | 3+17 | 4+12 | 6+16 | 7+13 | 8+14 | 9+15 |
On some connectors pins 18 through 25 are already connected. If they are not connected, connect them. Do not connect a wire from pins 18-25 and a ground wire to anything, just insulate it with electrical tape and leave alone.

Carefully fold the wires, put wires inside the DB25 connector and assemble the connector.

How to use the Toshiba BIOS password removal tool: connect the plug to the parallel port on your Toshiba laptop and turn on the laptop. You should bypass the BIOS password and the laptop will boot directly to the operating system.
You can find and purchase the BIOS removal plug here. Before you buy, make sure it works with your Toshiba laptop.
UPDATE for all Toshiba owners:
Some newer Toshiba laptops can start asking for the BIOS password even if the password has never been set. This affects the following models: Satellite A100, A105, A130, A135, A200, A205, L35, M200, M205, P100, P105, P200, P205 and probably some other models.
Before you can use the laptop, the BIOS password has to be cleared.

@ vadim,
Попробуй такой вариант.
Отключи блок питания и вытащи батарею. Теперь нажми на кнопку пуска держи ее несколько секунд. После этого воткни блок питания и попробуй нажать на кнопку пуска еще разок. Может помочь.
Если не помогло, попробуы вытащить модули памяти по очереди. Может один из модулей сдох.

ноутбук toshiba tecra a8 – Был извлечен аккумулятор когда ноут находился в спящем режиме (ОС Windows XP). Теперь при включении после заставки Toshiba выдает черный экран и следующую надпись – “Resume Failure and Press any key to continue” в верхнем левом углу. Нажатие клавиш никакого результата не дает, ноут висит и ничего не собирается делать. Не грузится ни с винта ни с дисков. Попытки запускать его без памяти и без жесткого диска тоже ничего не дают. Игра с биосом – нулевой вариант. Подскажите, может кто сталкивался с такой проблемой, что делать то теперь с этой кучкой металлолома? Просто даже не знаю что могло вызвать такую проблему и как от нее избавиться. Заранее благодарен за любой дельный совет.

@ roman,
Take a look at this video explaining how to remove BIOS password on a Satellite A135 laptop.
The guy explaining how to remove the password by shorting two jumpers (T and U). They look like engaged gear teeth.
NOTE: he’s using a jumper but you can use a regular small flathead screwdriver to short those jumpers.

@ satwinder singh,
Unfortunately (or fortunately), Tecra laptops are more secure than other Toshiba laptops in the consumer line.
In order to unlock the BIOS, it’s necessary to call Toshiba and ask for the unlock key. But this could be done only by authorized Toshiba tech.
I guess you’ll have to take your laptop to the authorized repair center.
