Dell Latitude 5500 Bios password

[Danny159]

Hello everyone,
I have a problem with a Dell Latitude 5500 laptop I bought last week from a local website, the seller told me it was password protected but the price was good so I bought it. I turned it on and of course it has a master password so I searched the net for solutions and identified the bios chip which is Winbond 25Q256JVEIQ and I desolder with the hot air station all good and well I read it with the programmer I have an EZP2023+ SPI Flash which for me is ok for now just that I only read it once I saved it twice in two different locations although I knew I had to read it 2- 3 times and compare it with HxD but I simply forgot, I found a password unlocking patch and did it, when I installed it back in place surprise the laptop won't boot, I installed the original bios back in place and still nothing. When I reinstalled the bios for the second time I noticed that a small resistor is missing which is connected with leg 3 of the bios I looked for the schematic or boardview but I couldn't find anything , only something similar where it appears to be a 49.9ohm resistor I soldered it but still nothing, please help me.
laptopul este Dell Latitude 5500

Here original bios

1st boot, press F2, write service tag, disable Absolute, save (Apply changes), restart. 2nd boot press Alt+F to exit manufacturing mode...

Thank you very much, but the problem is that it doesn't start even with the original bios, could it be the 50 ohm resistor that I lost? I think its value is 49.9 ohm according to the schematic.

Hi!

I kindly need your help with a DELL Wyse 5070 thin client which has locked BIOS settings (I want to change the boot order but I have to provide a password first). Is it possible for someone here to help me ?

I am attaching the original bios dump of the machine in question.

I would really appreciate any help.

Thanks in advance!
