Bios Bypass on Toshibe Satellite

I have a Toshiba Satellite that has the power-on password changed from the original one set. I need to clear the bios but don't want to have to dismantle the portable to remove the battery. The portable prompts for password on start and I cannot therfore use a bios clearing utility from DOS etc. A local dealer has told me that a tool is available from Toshiba for dealers only and they can reset the machine for £50 sterling!

Can anyone advise of any tool that will do this for me as I want to be able to sort it if it happens again.

Many thanks - Pat Black

The tool usually involves using a spcial plug hooked up to one of the ports, and allows resetting the CMOS.
I do not think that you will be able to get this anywhere but from Toshiba.

Also- Not all laptops have removable CMOS batteries.
I would check the maintainance manual !

I hope this helps !

If it were cheap and/or easy to circumvent, it wouldn't be very effective.  I'm afraid you'll just have to take it in and chalk this up as a learning experience.

No tool is needed.  On the Satellite models the CMOS battery is under the keyboard.

Remove the "keeper" that is at the lower edge of the keyboard.  It just snaps out.  Then the bottom of the keyboard can be lifted up and the keyboard "folded" up against the screen.

In the area under the keyboard you will see one or two batteries.  Remove them both and let it sit for about 30-60 minutes.  Replace the batteries and the CMOS will be cleared.

There is a tool called KILLCMOS however it has been known to totally destroy your BIOS making the computer inoperable. I've tried only twice and it did work, however it will reset BIOS to default. I have not tried this on a Toshiba laptop and their BIOS is unique compared to others.

OK, I give up.  I've been prodding at my Toshiba's keyboard but can find no such thing.  On both the top and bottom edges are single piece notches that go under the lip of the case.  Under the spacebar is the only likely looking candidate, but the spacebar doesn't want to move.

The question here is WHAT IS THE MODEL? Not all Toshiba laptops can have their CMOS cleared and or the password removed or cleared!

Newer toshiba laptops have just as high security features as IBM thinkpads.

There is a security chip on newer Tosh laptops. There is a password clearer that connects to the LPT port and sometimes can be found on Ebay.

But like I said, newer models need the password chip replaced or cleared in order to remove the power on password.

Magarity, the "Keeper" is not part of the keyboard it's part of the caseing above the mouse pointer and below the keyboard.

Bite the bullet and spend the money.

I have had several Satellites pass before me that have had similar password problems and they can only be cured with the Toshiba Tool, removing the battery doesn't fix this problem (been there tried that) either.

What model satellite do you have? Also if you happen to know the vendor it was purchased from?
Most likely a lost though.
