    Problem with the HP Endpoint Security Controller - HP ProBook 450 G8

    Notebook HP ProBook 450 G8
    ProdID 2K8L1LT#AC8
    Mother: DAX8QAMB8D0 REV D

    The device had bootloop issues. I reprogrammed the EC BIOS and the main BIOS, extracted from an HP 440 G8 with the same motherboard, and I was able to start the device. However, every time I turn it on, I get the error 'There is a problem with the HP Endpoint Security Controller in the unit.' I tried disabling several security options in the BIOS, but the error still appears. Additionally, when I attempt to update the BIOS, both BIOS chips get corrupted again.

    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.

    🛠️ 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

    ZBOOK 14U G6 Corrupted HP endpoint security and HP Sure Start (BIOS REQUEST)
    by lazaro.089
    Hi, I have this laptop with a problem, when turning on every time it shows an error message for the HP endpoint security.

    I tried and flashed a BIOS I found (U367-32Mb) and it worked for a couple of days before it showed up the same error again.

    Can you help me get rid of this error. Here are both my dumps (U366 and U367)

    I have some basic skills with Hex editors, if it isn't much trouble, can anyone explain what should I modify so if this problem shows up in another laptop I can fix it in the future?...
