@me4varun
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.

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?

Thanks!!
