Use tools like UEFITool or PhoenixTool to extract the raw .bin from HP’s own sp123456.exe file. The official ROM is always safer than a dump from another person’s laptop (which contains their Serial Number and MAC address).
The HP ProBook 640 G2 uses a firmware architecture typical of modern business-class laptops: an AMI/HP-customized UEFI firmware stored in non-volatile flash memory. A "BIOS BIN file" for this model usually refers to a binary firmware image (often with .bin extension) used for recovery, reflashing, or advanced modification of the system firmware. This write-up explains what the BIN contains, legitimate uses, risks, how to obtain and apply it safely, and best practices for enterprises and technicians.

Here is the hard truth: There is no magic “exclusive” file. Boot to DOS USB and run: dmifit /s
Websites selling these files for $20 or forcing you through survey scams are repackaging free dumps from Russian forums like Lab-One or Badcaps.
Real technicians know that a “clean” ME region file is often better than an “exclusive” dump.
This is the most common scenario. The laptop powers on (fan spins, LEDs light up), but the screen remains black. This is often caused by a corrupted BIOS due to a failed update, a dying CMOS battery, or sudden power loss during boot.
