Buddy, sorry, I did the whole procedure that you describe before, the only problem that I found was that I pass the power on password but still my computer is asking me for an Administrator password, seem to me that my laptop got both Power on password and Admon password.

In your sample the computer pass ´cause you have only the Power on Password, can you give a hand on that..thks

this works by adminpassword and by power on password when stringent security is disable!!

hello not you move, but is supposed to disconnect the battery

cmos connector cable with a red and black and leave it for several hours and

still gives me the same problem, the power-on password can help me

The admin password he is speaking of is not in windows, it's the bios password. There is a power on password, but in order to change bios settings there is an admin password as well. Clearing the cmos should reset it. However if the procedure didn't work for you then the password isn't stored in volatile memory and a simple cmos drain will work. It's cheaper and simpler to buy a replacement logic board for $40 than hours using solder joints to attempt to reset the bios.

2.- Hacer el corto en el chip EEPROM no siempre funciona los pines a juntar con el 4 y el 8 (Tierra y voltaje) (GND & VCC). Esto no permitira volver a poner nunca mas un password nuevo a menos que cambies el chip de la EEPROM por uno nuevo (Una persona calificada tiene que hacer esto).

1.- Quitar la bateria solo funciona en algunos modelos de HP y Compaq NX6320 o HP 530 por ejemplo y entre otros modelos que tienen 2 opciones para almacenar la contraseña de la bios en el CMOS y en modo super seguro en la memoria EEPROM.

Necesitas bajar el manual de servicio de tu equipo y leer que opciones tiene, pero claro esta que el password esta en la EEPROM sera imposible sacarlo.
