Need to obtain the BIOS password for Dell Latitude with serial number ending with -D35B, download the following.
For an example, I have a Dell Latitude CPi with serial WHZQS**-D35B.
I obtain the BIOS password as: d5g3xts5
The hard drive password is then required, using the HDD serial of HRCHRLL0275-D35B.
I obtain the hard drive password as: djb2f5eq
Note: if your serial number has ‘*’, include them.
Thanks to a thread at techspo.
