Don't mess with short circuiting, dellpasswords.com
have dell bios password from dell with older and newer bios password
just require both passwords from them,

as you noticed dell have now 2 bios password depending on the bios version, usually A9 - 2011

If you are really sure that it was you who set that password, and that the current password is correct, the possibilities are, I think, three:

- the BIOS memory got somehow corrupted. You have to unlock the system by removing the battery (the access port is underneath - check the service manual on the Dell support site), and reconfigure the BIOS after it has reset.

- someone changed the password. Same solution as above. Well, unless you can get culprit to 'fess up and cough the new password.

- the keyboard is sending out the wrong keys. This may happen for several reasons, mainly:
* Software: you may have NumLock or FnLock activated (or even Caps Lock with a broken LED - try setting the various keylocks and check LEDs go on and off). If your password contains the characters U-I-O-J-K-L-M, that could be it; or *Hardware. This may happen on some platforms (I'd have bet Dell Inspiron wasn't one of them, but...), and it is "as if" one of Shift, Ctrl or Alt keys "stuck". Magic as it may seem, try pressing each of those keys three or four times before re-entering the correct password.

Adminstrator password problem


If this is a white and grey screen, before windows starts, it's a system board password. To clear this you will need to contact dell, have your service tag and express code ready, and if you haven't already, you will need to register ownership with Dell. I posted a link at the bottom for phone numbers of Dell's support. Dell is great in the fact that they have a master code for each of their machines.

However, if this is a windows password, which I don't believe it is, you will need to start windows in safe mode by pressing F8 at start up. Then log in under administrator and clear passwords in each user account.

Here's the link, the phone numbers are about half way down the page. You'll just need to give them a call, it won't take very long, I've done it a several times with Dell machines I've purchased at auctions.
