DELL back door passwords. (all )

Lost BIOS PassWord or lost HDD passwords.   


I suspect all Dells that show the window (PoP) below at wrong password entered 3 times or hitting the Enter key 3 times will be cured easy as per below.
My Dell Laptop is e6540?  ( Mine:  A Slide show of  parts inside )

All you need is this  https://bios-pw.org/
Lost PASS words is only $2 to fix or free.  HDD PW looks near same but first line as hard-disk drive.

Dell is 100%  is almost useless here PW lost, they will demand matching your name now,
with name on warranty , registration, if never done that ,you fail.
no name can not match real names.
"If so, start by registering the system in your name - you will need the current registered owner's name.  If you don't have that, contact the seller for the details - Dell won't transfer the system into your name without that (in which case, return the system to the seller for a refund)."

Ebay seller has $2 PW unlocker, (money back promise) User ID pete-20-10

Doing the PW reset:
The PW is case sensitive, nothing new there.
Please type the BIOS password wrong two or three times incorrectly,  to get magic Dell code.
To enter the new  back door code. type CONTROL(left)+enter at the end. (using the suppled code)
or it fails.
