Hello, I have found on pages 2 and 3 that user Lordformat had the same issue like me. It is about Dell E6410, locked BIOS, suffix 2A7B and not-working password. I tried 3 keyboards, tried enter, ctrl+enter, ctrl+enter twice.
I had few the same models before, with the same suffix and BIOS version and it worked, but I have 2 models where passwords dont works.
I'm really not too certain here since all Dell BIOS that I've seen so far have a 4digit post-fixed code that denotes the version of the BIOS firmware.
Since this code is specific to the firmware version running, it only appears on-screen when the crypto-based service manager is invoked. Could you send me a photo of your lappy screen displaying the service tag? Perhaps then I can figure it out.
In the meantime, here's the verious bypass keys based on your service tag with various 4digit codes; try each one by carefully entering the 16 digits and then hold left CTRL while pressing ENTER.
