About this board

This thread is for the HP EliteBook 840 G6 ZBook 15u G6 with main board 6050A3022501-MB-A01.

The board was manufactured by Inventec for HP. Inventec board numbers start with 6050A, so you can confirm it on the PCB silkscreen.

Files listed for this board
  • BIOS (full SPI chip dump, .bin)
  • 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.

Have a tested file for 6050A3022501-MB-A01? Reply below and help the next technician. Looking for something else? Search all files in the File Finder.

This didnt work . just random reboots and no post
You need to write these two bios at same time if you did this then there will no bios problem
Verify problem by beep codes.
In this model you should get beep errors sound in speakers
 
Then check replacing bios chips and check motherboard
There is a bios file i got here that worked with your ec bios bin but there is a manufacture unlock mode message . can you fix it with my information , thank you .
