Hi Ed;
This is issue has resolution as it has been published on Toshiba's Official Support Website. It seems you need to go to an Authorized Toshiba Center. They have a special tool to re-flash your BIOS and it will resolve the issue. I am adding the original text and link for the solution below
Good Luck

Issue
The computer models listed above may display a "
Password ="
prompt when the computer is turned on, even though no power-on password
has been set. If this happens, there is no password that will satisfy
the password request. If the computer is turned off and back on again,
it is very likely that the same password prompt will appear. The
computer will be unusable until this problem is fixed.
If
the problem has not happened yet, you can prevent it from happening in
the future by upgrading the BIOS to the newest version.
The
occurrence of this problem on any particular computer is unpredictable
-- it may never happen, but it could happen any time that the computer
is turned on. If this problem does occur, it will be necessary to send
the computer to a Toshiba Authorized Service Provider, who will fix the
problem at no charge to you.
Resolution
If this problem has not yet occurred on your computer, then click the following link to download and install
BIOS version 4.00. This BIOS displays a power-on password prompt only when a power-on password has actually been set via the BIOS Setup program.
You may also browse for a newer version of the computer's BIOS at pcsupport.toshiba.com.

the problem has already occurred on your computer, then please make
arrangements with a Toshiba Authorized Service Provider to have this
problem fixed at no charge. To locate a Toshiba Authorized Service
