Re: Dell Latitude E7470 bios repair

Unfortunately I couldn't find the EC file for you, in the unzipped file there is a file named "1 -- 2 Embedded Controller vA.16" but the size is 256KB.

tried but with same issue. some bios files that i've tried No changes can be made on bios setup. it always comes back to default. maybe a good EC file could resolve the issue... thanks...

Try this one,give it a few minutes to statrt/restart. If it boots up ok then run the latest bios update from dell to update the bios and EC .If it doesn`t make any difference the problem isn`t with the bios.

Here you are, your original dump with with 1.05.03 version bios update, same as in your corrupted dump, try it and come back with some feedback. If the problem persist, I'll clean the ME firmware additionally.

Edit: Again, we've replied almost at the same time with Hardware1, I leave the dump I prepared, it is better to try it first, because it is with your factory ME firmware, and for me it is better to stay with it, but if as I said the problem persist, try the Hardware1's one - it has clean ME firmware.
