    Request for BIOS files for HP EliteBook 840 G6 (PROD ID: 4WG30AV)

    Hello,

    I have an HP EliteBook 840 G6 with the following details:
    • PROD ID: 4WG30AV
    • Serial Number: 5CGO28HLD
    • Motherboard model and revision: currently unknown, as I have not disassembled the laptop.

    The laptop does not power on due to what I believe is a BIOS issue. I am looking for the two BIOS files for this model, approximately 16 MB and 32 MB, to reflash the BIOS chip directly using a programmer.

    I have already checked the official sources and several forums but could not find these files for free. If anyone could provide these BIOS files or guide me to reliable free sources, I would greatly appreciate it.

    Please let me know if you need any additional information from me.

    Thank you in advance for your help!

      I’m having an issue with my HP EliteBook 840 G6, PROD ID: 4WG30AV — it won’t turn on due to BIOS problems. I need two BIOS files for this model: approximately 16MB and 32MB versions, to reflash the chip directly using a programmer.

      Unfortunately, I haven’t been able to find these files for free on official sites or forums, and some places require payment to access them.

      If anyone can share working BIOS files for my model or point me to reliable free sources, I would be very grateful! I’m ready to provide any additional information if needed.

      Thanks in advance for your help!

          HP Elitebook 820 G4 BIOS repair assistance required

          Hi guys,

          If someone would be able to provide some expertise, I'd be very grateful.

          BIOS Corruption - Cause
          So I managed to corrupt my machine by installing linux and enrolling custom secure boot keys. I did choose to enroll the Microsoft keys as well, to prevent any potential bricking due to 3rd party drivers from HP being signed with those keys.
          After doing that, and rebooting(it did boot, powerLED, fanspin etc.), the laptop did not give any video output on the LCD or video connectors. I think I was able to get in BIOS and trigger the beeper by pressing ESC....

          The right BIOS Programmer - The right software (HP Elitebook 820 G1, 840 G2) no soldering, EC, DMI, ME
          by STKR123
          Greetings badcaps community,

          I havent done this for a long time and want to start it all again, after some evil and annyoing illness.
          So I apologize in advance, if some phrases might sound a bit like gibberish or illogical to you.

          Im trying my best to fully describe what I plan to achieve and hope I was choosing the right sub-forum for my new adventure.

          I have a Elitebook 820 G1 and a Elitebook 840 G2 here.

          These ask for a password when entering the BIOS, but boot just fine from the internal SSD.

          I learned that desoldering...

          🛠️ 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
          ...

          Elitebook 850 G5 BIOS bricked
          by Guest
          Hello,

          I have an EliteBook 850 G5. After a Windows update, including a BIOS update, the notebook turns on, but the screen remains black, and the fans spin at high speed—nothing else happens.

          I assume the BIOS update failed, so I searched for the BIOS chip.

          I found a Winbond chip located between the RAM and the hard drive, which has a size of 32 MB.

          However, the BIOS update available on HP's website is only 17 MB in size. I used the update version that was previously installed when the notebook was still working.

          Can the corrupted...

          ASUS Zenbook Pro Duo UX8402ZA BIOS
          by pirati
          Hello everyone,

          I recently bought a non-working Asus Zenbook Pro Duo OLED UX8402ZA that was listed for parts only. The seller mentioned that it had no display output but that the charging lights worked.

          When the laptop arrived (without a charger and SSD), I connected a charger and confirmed with a multimeter that it was charging the battery. However, when I tried to power it on, only the backlight of the secondary display came on. There was no image, and it didn’t boot into the BIOS.

          I decided to try flashing a new BIOS, but since I didn’t want to desolder...
