Dell Precision 5520 bios password

Re: Dell Precision 5520 bios password

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.

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.

Re: Dell Precision 5520 bios password

I used a QWERTY keyboard and it didn't work

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.

THANK YOU
does not work
I have tried before
Dell HDD Serial Number (old) tttttrrp
Dell from serial number kN6BrG9kM1LJZI[7
16RGIkInkWmrFjRx

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.

Re: Dell Precision 5520 bios password

...It won't work if you type that in lower case...

Good morning

PS: I used UK keyboard, conclusion is it doesn't matter which keyboard you use as long as you type it correctly...

Well, it depends on the characters of the master password.

Re: Dell Precision 5520 bios password

Use Qwety US layout keyboard, with upercase use Capslock button do not use Shift button.

Hi thanks a lot, it worked perfect, one thing i must mention here is you have to type all your system info & code in upper case as displayed in dell screen.
It won't work if you type that in lower case, i was making that mistake, then i thought let me give it a try in upper case & it worked instantly.
