If someone were willing to help, they wouldn't be able to do so by the lack of additional information (E7A8 code).
Most likely your computer may still be under warranty, an advice, register it at www.dell.com, wait 7-8 days and then contact them through their chat and ask for the master password.
you need a Programmer to read bios dump there is many programmer available in the market or online but if you are looking for cheap price than go for ch341
update:
it turns out that the old method work here
you just need a password clean dump, replace the ME region with the one from
the pc's original bios , flash the modified dump
and VOILA!!!! works like charm.
thanks for those who tryed to help and for anyone here in the forum.

can you please elaborate more?
if you don't have time to write step by step then just give us hence like what tools to use and what componnent to keep and what to replace/swap
it seems more than one member here know how to do it and i believe them they do it for free but come on what sense they are trying to make here, isn't it about knowledge?
Before you buy CH341A, Take a look on what chip you have to read/write.
Then go to software programmer and look if that chip is supported.
And one more thing. You will be surprised when you discover that CH341A have 5V on data lines (pin 1, pin 2).
I recommend RevelprogIS.
Thank you! I will be reading the bios chip of the latitude 7400, what does that mean in terms of voltage on the pins? It's going to be my first time. Can I damage or fry my chip?
