Exclamation toshiba satelite pro y contraseña en bios

Hola.

Tengo un compañero al cual le han cambiado la contraseña de su portatil (un putada de mal gusto) un toshiba satelite pro y le resulta imposible acceder, pues la dichosa contraseña la solicita el portatil nada mas arrancar, antes de incluso de acceder a la bios propiamente dicha, consultando por diferentes foros he probado varias opciones para saltarme, craquear o resetear dicha contraseña, pero esta se encuenta en una memoria del tipo ¿ "eeprom" ? y me ha resultado imposible. podria alguien de vosotros ayudarme y ayudar a mi amigo. gracias.
metodos probados:
-quitar la pila de la placa base, resultado nada de nada sigue pidiendo la comtraseña de marras.
-quitar la pila y dejar el pc durante dos dias sin corriente, igual resultado.
-crear un disquete o keydisk toshiba,(cambiar los 5 o 6 primeros digitos despues de sector 1 o cero, es siguiente a el sector de arranque con un editos hex), igual resultado.
-lo de crear un cable modificado lpt es imposible pues no poseo un puerto de estas caracteristicas.
-lanzar el pc desde un 9 piso y esperar de con el golpe se resete la contraseña...? aun por probar.
informacion adicional:
PC: Toshiba Satellite A100-914.
MODEL:PSAANE-02C00NSP
BIOS: phoenix css 2005 q4. ver. 5.10
gracias por cualguier ayuda.
Un saludo

Toshiba tiene muy buena seguridad. Te dejo un método que ha sido exitoso en el modelo indicado abajo, ya que no puedes usar el loopback.

Reset Bios Password en Toshiba Satellite A135-S2386


1)Remove Laptop Battery

2)Take off Memory Cover(underneath - square cover, Sits in middle of laptop 1 retaining screw
3)Using two thumbs spread spring clips to outside and pull out RAM memory.
4)Remove clear vinyl label opposite RAM memory slots in upper left corner( laptop battery slot is on right, DVD drive is facing away from you)
5)Using a magnifying glass (unless you have perfect vision)in the upper left corner you will see JOPEN1 with a white silkscreen square next to it . Inside the square you will see what looks like the letter T over a U. Using a metal paper clip short the U to the Silver 1/4" post connecting the motherboard to the laptop case(this is your ground, it is located above what looks like a silkscreen outline of a chip)hold for 25 -30 seconds.
6) Place back your RAM memory, put in the laptop battery and test start laptop. you should see a selection of F1 or F2 for setup. Using the F2 gets you into the Bios menu where you reset the time and date. Then Tab over to the SECURITY setting tab and change your passwords. Now hit F10 key ,yes to save and your done!

Note: if your having trouble your most likely grounding the ground(that blob of solder about 1/8"dia on both ends of the "silkscreen chip outline"


Te dejo unas capturas del método:



y ésta:




Por último:





Salud.

Gracias KTANE, pero el modelo de placa que me muestras no es el mismo que el que tengo, es decir, el mio es el modelo TOSHIBA SATELLITE A100-914; MODEL PSAANE-02C00NSP.
He intentado encontrar los mismos tipos de conexiones, pero a pesar de estar mas de 2 horas me ha sido imposible.
Gracias de todos modos por tu ayuda e interes.

Predeterminado reset bios satellite A100-914

Hola, deciros que he encontrado una solucion perfecta, es increible lo sencilla que es y funciona perfectamente, yo la he probado personalmente y vuelvo a repetir es increiblemente facil de hacer y funciona.
Al iniciar de nuevo el ordenador no pide clave ni nada parecido y sin perder datos del HDD, ni configuraciones de la bios ni nada una maravilla.
Expongo la misma solucion una basica y otra mas detallada.

Un Saludo.

Fixing BIOS incorrect power-on password promt on Toshiba Laptops
Submitted by Anonymouson February 4, 2008 - 3:48pm
Hardware
I found this info ever several blogs regarding this problem. It is a really easy fix, with just a little bit of work and patience. I have a Toshiba Satellite A105-S4014. This should also work on a A100 since they are of the same family.

1) like always with anything that you do when taking your computer apart, take out the battery and unplug it (common sense)

2) Remove the plastic cover piece above the keyboard, called the "keyboard bezel". this is the piece where you can see the speakers. This page gives several pictures as to how to do this.

[Solo usuarios registrados pueden ver los links. REGISTRARSE]

...
**I found it a little bit difficult to get the plastic retaining clips to "pop" loose, but if you are careful, you can use a small screw driver and slowly "wiggle-pry" between the two screen mounts. this is done with the screen all the way back. you could use a paper clip with a little 1/8" bend at tip to do this also. (it is a tight working area) Once these three retaining clips have come loose the others are fairly easy to "pop" Just be patient and work it slowly. once this is bezel is off the rest is super easy.**

3) Remove the keyboard. Remove the two screws that are evident once the bezel has been removed. These hold the keyboard in place. Lift the keyboard up from the screw side and the retaining clips at the front of the keyboard will lift out. (there is no need to pry here). Once the keyboard is loose you will have to either leave it connected, just off to the side, or disconnect it from the mother board. The keyboard cable connector has a black clip along the top of it. just lift this clip up a little and the keyboard cable will slide out. (the keyboard cable does not have a fixed connector, but is just a ribbon that is held in place by the black clip along the top of the keyboard cable connector) Once you have removed it you will better understand what I mean.

4) Remove the wireless card. It is the only card visible at this point. It is connected by metal spring clips. just unclip in a similar fashion as removing ram. You do not need to disconnect the wires connected to card, just move card over to expose area below card.

5) This is where the magic is... you will see C88 clearly labeled right next the jack that the wireless card plugs into. There are two little solder squares (approx 1/16") at this location. *** At this point plug the power adapter to your computer again. ***
You will have to jump the two solder squares at label C88. I used a paper clip to do this. I used pliers to bend a 1/8" long "L" and then "scuffed" up the paperclip with the teeth of the pliers. (my first try at this did not work because the paperclip had a varnish coating on it and did not adequately conduct electricity.) Once you have your paperclip set up (or the one you used to pry the bezel with) hold it in place on these two solder contact squares and press the power button to boot your computer.

6) Your computer should boot right up and bypass the bios password, which is now reset/ erased. (You might see the Windows Error startup screen that gives you different options of start up to choose. If you disconnected your keyboard, just wait for screen to time-out and it will continue on its own) Once you have booted into windows use your mouse pad to shutdown, via start-shutdown method.

7) Disconnect your power. Reinstall your wireless card and keyboard (with screws). Don't reinstall keyboard bezel at this time. Once everything (but bezel) is reinstalled, restart the computer with battery and AC adapter connected. This should boot right into your computer without any trouble. (if for some reason it does not boot up correctly and asks for the bios password again you will be glad you left the bezel off. just redo the steps again.)

8) Go to Toshiba and get the latest Bios for your laptop. here is the link:

[Solo usuarios registrados pueden ver los links. REGISTRARSE]


Choose your computer in menus provided. download the latest bios version. Using a cd burning program like "Nero" burn the image file to a cd. reboot computer and press F12 to choose boot method and boot from cd. this is the best way to update your bios. there is a way to just run from windows but I do not recommend it. This is a way to get into even worse trouble. If you need software to burn Image files just go to Nero and download their trial. It will work for 30 days and will work perfectly for this important task.

9) If for some reason you are still having trouble feel free to email me at

I hope this has been of help to those as frustrated as I was. It is long winded but I like things explained fully before diving into a toy that costs a lot of money. I also do not like to send my computer away to some company that may or may not invade my privacy. I have a lot of personal stuff on my computer, as we all do. When the fix is this easy, I would rather do it myself.
