Hi All, hello Ghost,
My problem is a DELL E7270 with full encryption , S/N: 7WRZKC2.
bios-pw.org/
offers hints for "SUFFIX" method to gain BIOS master pwd.
Q0: I'm missing the part of what the 6 suffix variations (-595B, -D35B, -2A7B, -1D3B, -1F66, -6FF1) are for?
The method is supposed to be a quick and easy way to recover BIOS passwords on laptops.
It is credited to Dogbert and Asyncritus.
It calculates MPwds, based in case of a DELL laptop on S/N number plus 6 (?) different suffixes.
I attached the first version: my S/N + suffix -595B.
Q1: How do I know it is the right suffix?
Q2: Which code offered (even in other suffixes) can be used as MPwd and exactly how?
I understand I dump (try/fail to introduce BIOS pwd) the machine > introduce the code that follows "Dell from serial number".
In case of first suffix is "lx73nha4" (see pic).
Q3: If it does not help, in hard reset how much time do capacitators need to go powerless after CMOS battery removal, if this method even works with E7270? I think it might have an eeprom, that is why I am trying the 'SUFFIX' method.
I would appreciate any help!
Regards and thanks,
Freddy
