    PS5 EDM-033 UART 80810001 Beep 1 second Ligth
    by Egidio85
    Hi everyone, I have a ps5 EDM-033 that beeps, blue light for 1 second and turns off.

    reading the error codes via uart gives the following code:

    80810001 General power failure (periphery, GDDR6, APU, data line shorted)

    checking the card I didn't find any shorts, Boot sequence is quite right 325 mA dropping to 9 mA.

    Using the thermal camera I can see the SSD controller and South bridge getting warm.

    if I press the power button the RAM also heats up, the processor doesn't seem to. in fact if I go to measure I don't have +1v CORE output....

    CPU replace | OEM Hash key poblem
    by Vusal
    first of all hello everyone
    If there is a short circuit on the motherboard of the HP laptop. The CPU was broken (i3-10th) I found a donor motherboard on ebay and replaced the CPU.
    The CPU on the donor motherboard had the OEM Hash key. But I did not check the OEM Hash key before ordering the donor motherboard.
    Normally, after changing the CPU, the motherboard started and the white LED light on the DC jack was blinking.
    The motherboard was in reset state and the current drawn was 60mah.
    I checked the BIOS information and added the OEM Hash key on the donor motherboard...
