About this board

This thread is for the Dell Latitude 3420 cyborg-l14 TGL NEW with main board 213105-1.

Dell had this board built by Wistron; Wistron board numbers are 5–6 digits plus a revision. Check the number printed on the PCB before you download.

Files usually needed for this board
  • BIOS (full SPI chip dump, .bin)
  • EC / KBC firmware, if the board uses a separate EC chip
  • Schematic (PDF)
  • Boardview (.brd / .bdv / .cad)

Common cases: dead board after an interrupted BIOS update, ME region errors, missing serial number or UUID after a board swap, or a password lock.

Back up the original dump first — it contains machine-specific data (serial, UUID, MAC, ME), and you will want it if anything goes wrong.

If you have a working file for this board, please share it below. More files: search 213105-1 in File Finder.

after flashing the bios the laptop turns on and asks for serial number, once the serial number is added the laptop turns back off and doesn't turn on until i program the new bios.

please upload EC bios also.
 
I tried flashing this bios.

the laptop turns on but there is no display.

other then that the system takes the load very smoothly and there is no beep sound

if only the display had worked.

Can you please take a loot into it?
 
already looked into this. And i think this not Bios related problem check Motherboard
I tried everything, the board seems fine
And upon using the build bios, the display turns on and asks for serial number and never turns again,

There are two bios chips, can you please send me both of them so that I could try for the last time.
