OK thank you. Soldered back. But the laptop does not turn on. The cooler works at high speeds, the screen is black
First boot will be much longer than usual just wait, if you have programmed and soldered the chip as it should everything will be OK, if not do it again.

Started up. Thank you Password removed. But the cooler constantly works at maximum speed
At first boot press F2, write the service tag, save & restart. After that at the second boot press Alt+F to exit manufacturing mode. And the fan will slow down.

Dear Sir,
I need help removing/unlocking the BIOS Service Tag password on my Dell Latitude 5520 laptop.
Problem details:
* Model: Dell Latitude 5520.
* Board ID (from BIOS file): TGL MB 8L 19819-1 (Southpeak15).
* Required Password Code: 3FE2 (BIOS Service Tag Lockout Code).
* Service Tag: (Enter your actual Service Tag from the laptop here)
* ​BIOS Status: I successfully modded the BIOS file and created FINAL_CLEANED_ME.bin (32MB) with a clean ME region (CSME 15.0), because the original dump was corrupt....
I have a dell 5410 with locked bios, than I dump bios from a identical laptop and I've flashed it. But now all system information are identical to the bios donator laptop, how can I write again the correct service tag and other infos? I attach the original loched bios bios, how can I extract the right infos? And how can I write it?...
