    If you`re going to use a bios from any intel machine check first if the ME is Initialised (Dirty) or Configured (Clean)

    For the endpoint error try the endpoint patch script at post #2 https://www.badcaps.net/forum/troubl...security-error , it will clear the NVRAM
    Thank you for your reply,You are right,the bin file is not clean,I tried this file from poste #2 which is clean,now the laptop works showing manufacturing mode ,the fan spins full speed, and late display.and no more security device Problem message.
    Any i dea please

              Can`t see the marking code the IC picture is too blurred. Check if a schematic is available

                Your main bios backup is only 65 bytes ,bad bad bad. Sometimes the endpoint error can be fixed using a patch script https://www.badcaps.net/forum/troubl...security-error

                                            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....

                                            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.

                                            🛠️ 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

                                            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

                                            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...
