How I got out of error 0199 purgatory

Question

So I locked up my Lenovo T61 pretty spectacularly on a Friday night. That will teach me to play computer nerd, any reasonable folk are doing something more productive on said nights.  What basically happened is that I thought that it was so cool that there were so many passwords that I could set that I in fact set them all and then made the BIOS sphincter tight, so that a password was required to breath funny. BUT the thing that killed me was requiring a supervisory password, not knowing what that was, and then setting it without knowing it. You don't record what you didn't know that you set.
DON'T TRY THIS AT HOME. ONLY POORLY TRAINED PROFESSIONALS CAN DO THIS STUNT WHEN THEY ARE SEMI-CONSCIOUS.
My story is detailed on this thread
          Please help - Totally locked out of T61
=============================
1. PART ONE: IN HARD DRIVE HELL
=============================
At any rate, these were the symptoms. If I rebooted, I received this error, no matter what I did the system kept politely but emphatically saying:
      ***** ERROR: 0199 System Security security password retry count exceeded *****
               Press [F1] to get into setup utility *****
I kept politely but gullibly (is that a word?)
Hitting [F1]
and getting into the setup utility, a trip to nowhere (you can change nothing). No matter what I did, [F1] did not pass go, did not collect $200 but went straight into the BIOS setup utility, in which I could do nothing.
The answer of course was to ignore the obvious and
Hit [ESC]
instead. I detail this partly because that approach, ignoring what the software told me to do and trying alternate responses, is what saved my behind.
So I figured out how to get into my HDD, but every time that I got on I got that **** 0199 error. And I tried everything that I could think of, all that I could find in help etc. So now the story continues in a second thread.
==================================
2. PART ONE: IN PASSWORD PURGATORY
==================================
I figured out my HDD and power-on passwords. There are five variants of extremely difficult to crack code algorithms that I use (OK they would be difficult for ME to crack, as in never). Trying variants of them using my usual suspects, I backtracked those codes.
But what about this supervisory password? And where could I try it, because I was locked out?
Get  into CSS (Thinkvantage Client Security Solution)
Move into <Enhanced Security>
Moved into <Unlock>
I noted that I could clear the lockout counter using my Administrator password. Hmm
Clear the lock out counter
This  appeared to allow me to do the next step, but it is not absolutely clear to me whether/not this step was necessary
Move into <Deactivate>
My memory is that at this point it asks you for your supervisory password in order to deactivate the chip.  I've turned off the supervisory password now (never again!!), so this is remembered. BUT.   AHA! Now you can
Try out those few variants of your genuine, it-is-really-me, Lenovo-approved passwords that you remember or (in my case) half-remember
This step took me forever, because it doesn't LOOK like you can enter a password. But once you type it in then you have the opportunity to hit enter. It will lock you out eventually, and I APPEARED to have to clear out the counter and reboot before I could try again. 
So at this point, I had these three passwords nailed down
          * Power-on
          * HDD
          * All of my Windows passwords
          * The holy grail, my supervisory password
A detour:
The supervisory password, by the way, turned out to be the HDD password that I remembered AND jives with one of the pieces of Lenono documentation that I combed for clues that I can of course no longer find. My best guess based upon my poking around is that there was
     1) My user HD password, let us say that it was
          Kermit
     2) My master HD password, e.g..
          Oscar
     3) THEREFORE the HDD that I remembered
          KermitOscar
     was in fact the USER + MASTER (duh) that I couldn't figure out
This is where I feel exceedingly clever, for no particular reason.
Again I was/been looping around, endlessly trying to find a place to enter the ***** ******* supervisor password, now that I had the thing. But there is nowhere to enter it!
     * You can't enter it when the BIOS fires up
     * You CAN enter it until the cows come home in CSS to no effect
     * Firing up Rescue and Recovery to enter the BIOS is equally useless.
So here is my simple cleverness, from the documentation "Using passwords."
When logging in, instead of entering your power-on password, use that supervisor password instead. In my case, if  instead of using my fingerprint to log in with
When Windows asks you to log in, I hit <Esc> and entered
First the SUPERVISOR password and
Then the HDD password
Instead of the regular
Power-on password and
Then the HDD password
Then you trip over from Kansas into Oz and VOILA!!
============================
PART THREE: BACK IN LENOVO OZ
============================
I am now recognized as the supervisor and can play again with things in the BIOS which were better left alone.
 My fervent hope is that some other person out there will not waste as much time on this as I did.
For 95% of you out there this will be dull stuff.
My guess/hope is that this post will stay posted. I am not giving away any nuclear secrets here, I figured it out on my own and/or it is in th edocumentation. If you were not just a few steps away from remembering your password this wouldn't work or be worth your time if the person had a password worth a ****.
I'm not paranoid or anything, it is just that all of the posts that I wanted to read were yanked offline like they were giving away nuclear secrets. If I have inadvertently said something that I shouldn't then don't just yank the post, tell me what I need to fix and I'll revise this to something less yankable.
Enough.

I have a similar problem. I solved the problem as you did, but clicking the eject button. However, it seems that I have to do this nearly every time. If I plug it in, it will sync and finish. "Do not disconnect" goes away OK. However, if I choose 'sync' from the file menu, it will sync and then not clear when finished. I have to manually eject.
