    HP 840 G1 Unlock MPM issue

    Hi,
    I have a bios for HP 840 G1 that shows this message: The Embedded Controller MUD data is not valid while MPM is locked, but when I accept, it says The Embedded Controller flash failed.
    Attached are images of the laptop model and error message, also bios dumps.

    HP G1 - Copy.zip​

    Can you please help me get rid of this error message?

    Thanks!

      MacBook Air A2337 (820-02016) USB-C Port Issue – Only Works in One Orientation (CC Line Problem?)
      by rounin
      Hi everyone,

      I'm working on a MacBook Air 2020 (A2337, board 820-02016) and running into a strange USB-C issue. I've gone through quite a bit of testing and part replacement, but I'm stuck — hoping someone here can shed some light.

      🛠 Original Issue
      The machine initially wouldn't negotiate 20V over USB-C — stuck at 5V.
      Diagnosis showed PP1V5_UPC0_LDO_CORE shorted to ground.

      I replaced U3100 (UF400) using a donor board (A2179), and the machine powers on fine now.

      ⚠️ New Problem: One USB-C Port Only Works in One Orientation...

      Hofmann geodyna 6300 Wheel balancer
      by Grouickman
      Hi there,

      First, I'm not sure it's the right section to post for this type of device, but could not think of something better.

      Ok, so my son (a mechanic) bought a faulty Hofmann Geodyna 6300 wheel balancer (which appears to be mostly a re-branded Snap-on wheel balancer).

      I'm looking for any resources (doc, manuals, schematics) that would be available for this device or anyone that would have any knowledge on this particular device (or its Snap-On equivalent).

      I'm trying to diagnose the fault(s ?), but I can't find any schematic (appart from the...

      Three 820-01700 32GB Logic Boards Same Issue: Won't Wake From Hibernate
      by ugamazing
      I have three identical-spec 820-01700 boards (2.6/32/512), and ALL THREE boards came to us with the same fault, from different sources: The boards don't wake from hibernation with the keyboard or lid, they ONLY wake when you press the power button. I understand this is a very minor issue, but the boards must be fixed!

      We will of course begin with the obvious (checking lid signals), but I couldn't help but notice these three boards were all 32GB variants. Has anyone noticed an issue relating to these 32GB boards in particular? I of course don't think it's a RAM issue, but it's bizarre...
