The password may be saved in flash memory that needs no battery to retain it.
There is surely a 'cheat' to reset the password but I suspect the method is not real public since it could be used to reset a stolen unit too. You might check for a retail outlet that sells Toshiba and call them to see if they can do this for you. Most service techs will want to see some proof of ownership before accepting it for resetting.

Bios password

Some Toshiba bios passwords can be reset using the Key Disk.exe utility, to do this you need a 1.44Mb floppy disk.

Format the disk using Windows and then with a hex editor, change the first five bytes of the second sector to 4B 45 59 00 00.

Then put the floppy into your machine and boot it up, you’ll be asked for a password, just press Enter.

Then when you’re asked to set the password, type Y then Enter, this will get you into the bios configuration where you can then type in a new password.

I have a tosiba tecra 9100 laptop that when I boot up it ask for a bios password, i bought from a garage sale and noone seems to know the password is there neway i can clear that password and start over...

There is a battery on the motherboard. Removing it for about 1/2 hour should clear the bios. There are several software methods also. Google 'bios password removal' to find one.
