The model # on the bottom is PP30LA, the Service Tag is G7QNXN1-1F5A and the Express Service Code 35296567309. It will not even let you go to BIOS without the password, states that the computer system is locked and it will not allow access to anything without the password. I have been browsing and have seen some suggestions about a jumper that is used on some models to reset or remove this password but I have yet to find it. Can anyone help? Thank you for your time. Have a Good One! Love, Peace and Perception

I have researched a lot about it, but nothing seems to work to unlock it.

Even contacted Dell Support, and they have generated a not working password for me.

So i need a method to flash an other bios to change 1F5A tag, then i can unlock it easily.
