    Dell Latitude E7440 - Unable to update BIOS

    Hello!

    There was a problem with the laptop that it won't turn on unless the BIOS settings are on default (without CMOS battery). However, I've fixed it with replacing both of the chips (EC+MAIN) and programming them.

    New problem emerged when I tried to update the bios (because the dump file was older and I couldn't find newer (A08 I believe and the new is A28))

    The update utility runs, finishes it's "Preparing to update BIOS", restarts laptop and that's it. Nothing updates.

    Found on some other forum to turn off the "Intel VT", tried updating through FreeDOS and with DELL BIOS Update (F12 on boot) and also, DELL support assistant.. no luck.
