    HP EliteBook 745 G4, 6050A2834601-MB-A01, Bios unlock

    Hello, I have a HP EliteBook 745 G4, 6050A2834601-MB-A01

    I think someone has had a go at this before as I can see the chips been refitted
    and all I am getting are FF FF FF FF when reading the chips.

    I have found some dumps online they work but its asking for a password.
    Would someone be nice enough to unlock these dumps please, I have
    tried RCUnlocker it says there is nothing to unlock in these files.

    Thanks so much.

                    [REQUEST] Dell G3 3579 BIOS Password & AMI Protected Range/BIOS Guard Unlock
                    by zenius
                    Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.

                    Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,...

                    HP Elitebook 820 G4 BIOS repair assistance required
                    by Wutru
                    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....

                    🛠️ 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...
