What an amazing thread!
I have a Dell Latitude E4200 and at first implemented a bios system pw, then later implemented a HDD pw through Dell's control point software. Both pw's were supposed to be the same. But I couldnt get the HDD pw to work! I think if I had a Bios Admin pw set before I set either the Bios System pw and the HDD pw-- I would of been fine. But because they were set already, the bios wouldnt let me change that. Anyhow... I knew I shouldn't of mess around with the biometrics/pw's. I've had probs in the past with a dell laptop on that.
I read through this entire thing... Took hours. That was after I called Dell Tech and was told I'd have to reformat and lose everything. Ha! Realized that I prob needed more than just a bios hack/whack job. Found the info about master pw's very interesting. I decided to try Dell support again. This time I used the Chat support.
Tech support is like a box of chocolate, you never know what you're going to get, and it's only as good as the tech on the other end. And if you do get a good one, (who has a brain and can think outside the canned scripted rhetoric) consider yourself lucky, because they don't last long there (phone support). They move on to bigger and better things.
After a few short minutes, I was provided with the master pw (which I am keeping for later reference) and was able to unlock/reset all pw's.
It didn't cost me anything, but I do have a current service contract. Now I can get some sleep!
P.S. Nice forum. Keep up the good work.
