Bios Password Locked Me Out


Does anyone know how to bypass/crack BIOS password of a Toshiba Tecra?
A friend of mine locked himself out and now cannot boot his machine!

Have you tried to remove the mobo battery for some hours? In some cases it will flush the stored pwd.

Some motherboards though have other types of technologies to store passwords (for example EEPROMs). In that case you will have to destroy the EEPROM chip itself (by short-circuiting it) to remove the password. You will not be able to set a new password on it again though afaik.

Some mobo has two battery to backup the BIOS a small one and bigger one.
And even some times the backup is done with capicitor
So some times it is puzzle to find it
Mostly you find it nearby the BIOS


all the best

And sometimes there's a jumper to clear the memory and reset the CMOS to defaults; usually on the motherboard specs in the manual...

there is certainly a jumper to clear the memory indeed of the motherboard. It s very frequent.

Would you still have the manual of the machine ?

From the Toshiba website the password can only be reset by a technician. However, from searching the web the answer depends on the model number. Some were reset by shorting particular jumper pins, some by using a modified floppy boot disk and some by a special parallel port dongle. Tecras appear to use shorting pins but again the procedure depends on the model and may not be as simple as clearing CMOS memory.

luckily, I have not had the opportunity to find out how easy or hard it is to actually reset the password.

I hope a pro can help you ... otherwise you'll have to open the notebook, that's always risky when one hasnt much time/patience/experience...
