    Write DMI information on HP Probook 640 G2

    Hello !

    I had an HP Probook 640 G2 computer that was no longer working (the physical chip bios had failed), so I could not read its contents.

    So I retrieved the bios data from an identical model, cleaned the ME region, then programmed a new chip and put it back in my computer where the bios was broken.

    The problem is that the information on the bios is that of the computer where I took the information (SN,FeatureByte,BuildId,....). I tried to use HP's DMITool (which I usually use for consumer computers) but I could not write the data to the bios.

    When I try to unlock the MPM mode I get the message "HP MPM protocol is not present".

    Does anyone know how to change this information? The RethoricalCheese password remover program shows this information, but I couldn't find it with HxD in the BIOS file... maybe it is encrypted?

    Thanks for your help!

      With an other HP DMI TOOL, I have this message : "MPM is LOCKED on this commercial unit. In order to proceed you will need to ordier a new SMC.bin file."

              Bricked HP Probook 450 G7 Bios questions
              by studdy05
              Hp Probook 450 G7 s# SCD0348W35 had a locked BIOS. Bought BIOS and EC chips off Ebay that were supposed to match this machine - the 450 G7. Flashed in the BIOS on chip i bought using a CH341. BIOS unlocked next boot. Some error to contact HP. Entered BIOS and reset to system defaults and rebooted. Machine worked fine but every cold boot the contact HP message popped and everything else worked as fine. Assumed the error was from EC chip not matching BIOS that i just flashed in. So i flashed in the EC that was supposed to match from the EBay chip i bought and instant brick.

              Ive got...

              🛠️ MSI GP75 Leopard MS-17E71 – No Display, Deep BIOS/EC Troubleshooting
              by macabook
              Hello everyone,

              I’m currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, I’m at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Here’s a full breakdown:
              🧩 Initial Issue
              • Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight
              • External display (HDMI) shows
              ...

              Need (unlocked) bios for HP Probook 450 G3 Notebook
              by the_raz
              I'm requesting a bios .bin for 2 of my hp Probook 450 G3's. Both of which I had forgotten the bios passwords. I stupidly flashed both of them with firmware "made" by the RCUnlocker software and I guess I shouldn't have. The last thing I did was flash both of them with RCUnlocker-fw thinking it would 100% work and left my programmer etc behind and won't have access to them for another 2 days so I figured I'd create a thread to see if I'd be so lucky that someone might have a working file laying around 😝

              novice user attempting first BIOS write on ASUS laptop
              by alphabetty
              Hello first post!


              Ok so after an (ASUSTek) optional Windows update, my old ASUS E403NA laptop rebooted and froze in the BIOS menu screen and was unresponsive so after about 30 mins I powered off and back on again. Now i just get a power LED and a black screen, I have tried all the basic suggestions and all the suggestions on the ASUS site, spoke to ASUS support who said I will need to pay for an RMA.

              The laptop is worth €50 so I won't be doing the RMA at god knows what price.

              So I have seen some videos where people have reprogrammed the BIOS...
