Must be typed in US keyboard layout ( your laptop keyboard is French AZERTY), so just use external US layout one, and the password is case-sensitive of course.

I doubt it doesn't work, but since you want to do it the hard way upload your bios dump here, and someone will do the unlock for you.

I'm sorry...
Hello everybody.

I have a Precision 5520 - 4XLKZF2-E7A8 asking for a password as soon as I turn on the "Dell Security Manager" equipment.

I tried both keys from the https://beta.bios-pw.org/ site without success.

Hello everybody

Your machine is equipped with Nordic Multi-Language Keyboard,
the password must be typed with US layout keyboard, try with the external USB keyboard with US layout. After entering the password confirm with Ctrl + Enter Enter.

@Vesko356 Thanks for the quick response.

I'm using an international US keyboard

I was able to unlock a 5510 easily with the password generated by the website https://beta.bios-pw.org/, but I could get into the BIOS with this 5510.

But the Precision 5520 is different, when I turn it on it already appears the message below.

Dell Security Manager

This computer system, #4XLKZF2-E7A8, is protected by a password authentication system. You cannot access the data on this computer without the correct password. Please type the system or administrator password.

Do you think it's the same BIOS password or is it something else?

Tried the keys below to no avail.

Yes, the master passwords are the same, you're just typing something wrong. Try again, it should work.

Re: Dell Precision 5520 bios password

Is it possible to change the service tag? I bought a Precision 5520 which is tied to another corporation, and you can't log in to yours.
DSTCD does not change

Your request doesn't meet the rules. Attached dump has been removed. Deliberately changing ID numbers (including WIN, IMEI and so on) is illegal and not condoned or encouraged in any way or for any reason here.
You may contact an official Dell representative office for further resolution of the matter by presenting proof of purchase/ownership.

DISCLAIMER: badcaps.net and its members do no support unlocking stolen or company-owned devices. The information given here is for personal use only, ie. you accidentally set a password on your own machine, you forgot the password you set a long time ago or you mistyped the password when setting it and cannot get in again.
Note that a device bought locked might also have been stolen if the previous owner cannot give the correct password. This is especially common with business-grade equipment (Lenovo ThinkPad…) that employees sneak out or do not return.

Re: Dell Precision 5520 bios password

Sorry, I forgot to specify that a qwerty keyboard is connected to the USB port.
I found this password: Q0H3ZtCB6tHZKIWW
No error: 0 = zero
and I've respected upper and lower case.
