About this board

This thread is for the Dell Precision 7770 with main board LA-L891P.

Dell had this board built by Compal; Compal board numbers start with LA- and end in P. Check the number printed on the PCB before you download.

What this thread covers
  • BIOS (full SPI chip dump, .bin)

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 LA-L891P in File Finder.
