My question pertains to understanding the control circuity inside a Dell PT434 type battery used in Dell E6400, E6410 and other Dell notebooks?

I need the EC firmware dump for Dell Latitude 5420, motherboard GDF40 LA-K491P Rev 3.0 (A02).

If anyone has this board and can share their EC dump from the 25Q80DV, I’d be very grateful.

I need to open it in UEFITool and exe or rcv file is not supported.
