After updating the microcodes in the bios of this wonderful laptop, I would like to be able to update the MEI in the bios too, it seems to be very difficult and risky but I am brave and I know how to restore an incorrect flash. I did not understand what are the main steps to perform this update, could someone at least clarify the steps to follow? What you do is great and I would like to learn in order to keep this laptop forgotten by dell and to help those like me who still have this great product.
