About this board
Files for the HP EliteBook 840 G4 motherboard, board number 6050A2854301.
HP had this board built by Inventec; Inventec board numbers start with 6050A. Check the number printed on the PCB before you download.
The BIOS image is 8 MB, so the SPI flash is 64 Mbit (W25Q64, MX25L6406 class).
What this thread covers
- BIOS (full SPI chip dump, .bin)
Usually needed when the laptop powers on with a black screen after a BIOS update, is stuck in a boot loop, or is locked with a BIOS password.
Before flashing, always read and save the original chip. It holds the serial number, UUID, MAC address and ME data for that exact machine.
