About this board

This thread is for the Dell Precision 5570 with main board LA-L402P.

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)
  • Schematic (PDF)
  • Boardview (.brd / .bdv / .cad)

Typical reasons to reflash: no power or no display after a failed BIOS update, a BIOS/supervisor password lock, or a corrupted Intel ME region.

Before flashing, always read and save the original chip. It holds the serial number, UUID, MAC address and ME data for that exact machine.

If you have a working file for this board, please share it below. More files: search LA-L402P in File Finder.

It is a Winbond W25R512. I will try and find a different one on some donor boards but may have to order another one as this is the only the second time I have seen a 512. I will keep you posted as it's truly weird that my Svod 4 shows every step passing for the chip, but then again, nothing is perfect.
 
Just wanted to tell you thank you so very much for the insight on this BIOS chip.. It's virtually impossible to find as every place here in the states is out of stock which I am assuming is a result of the failures. I found them in China and awaiting for them. Thank you again for the much needed insight so I know what to look out for with these in the future.
 
Still stuck on Dell Logo and fans half speed and not a single blink code. Maybe I should just run it over with my car. Been working on this for 4 days. sigh
