If you need a full 16MB dump (for a CH341A programmer, etc.):

⚠️ Critical warning:
Using the wrong dump can permanently brick your laptop. Always match:

The best BIOS bin file for resale or multiple repairs includes cleared DMI. Here’s how to do it with a hex editor (HxD):

Doing this makes your BIOS image “golden” — ready for any 640 G2 motherboard of the same revision.

Once you have your pristine .bin file, here’s how to safely write it. You’ll need a hardware programmer.

To understand the value of the BIOS bin file, one must first understand what the file actually represents. In the context of the HP ProBook 640 G2, which utilizes the Intel Skylake architecture, the BIOS is stored on a SPI (Serial Peripheral Interface) flash chip, often a Winbond or Macronix component soldered directly onto the motherboard.

Unlike the executable update files (typically .exe) provided by HP for end-users, a .bin file (or sometimes .fd, .rom, or .bios) is a direct sector-by-sector image of the data residing on that chip. It is the digital DNA of the hardware.

This binary file is not a singular, monolithic code block. It is a complex container that includes:

The "best" BIOS bin file is one that maintains the integrity of all these regions. For a repair technician, obtaining a clean, uncorrupted version of this file is often the difference between a functioning laptop and a doorstop.

Before you flash anything, open the bottom case and locate the motherboard. Look for these codes:

Note: The ProBook 640 G2 uses a 16MB (128Mbit) chip for the main BIOS region.
