Re: Dell Latitude 7400 Bios Password 8FC8 Suffix

can someone help me clean the me region for this dump of 7400? I damaged the original bios chip when desoldering. The laptop starts up with a delay of 20s.

I tried the normal procedure i use but it does not seem to work on this newer generation

Re: Dell Latitude 7400 Bios Password 8FC8 Suffix

there is no original(chip not recognized by programmer after desoldering- temp might have been too high) , this dump is one i found on the internet(remont-aud).

I tried to folow the guide from win-raid forum, but this bios is the first to have OEM Public Key Hash and i never cleaned a bios like this. Original problem of laptop was bios password, with this dump in a new chip, i still have password but delayed start

try..

thanks, it doesn't work , i saw that the bios is perhaps newer because it looked a bit different(a warning message had a new design) .

Did you do anything about the OEM Public Key Hash?
