    820-00165 Random green light on charger
    by ahoonid
    Hey everyone,

    I have a MacBook Air 2017 with a weird problem. The MacBook was totally dead at first and the culprit was the C7430 capacitor which was obvious upon initial inspection as it had a fracture on its surface.

    The F7140 fuse was also blown so I changed them both. L7130 due to corrosion was also replaced. Now everything works again. Laptops turns on and everything seems reliable at this point.

    The only issue that I'm afraid might bite me in the ass later is the magsafe light as it randomly changes light from orange to green while charging. Other times...

    The receiver is going into protect mode when switching inputs or enabling/disabling A or B speakers on the front panel. I removed the protect signal from the main microprocessor and the system played normally on FR and FL speakers from an analog input. I measured the protect signal and it's attached.

    Intel NUC8V5PNB help identify component
    by cronix_it
    Hi all,
    I'm trying to fix this NUC, whose sata power cable was somehow shorted (not yet clear).
    Standby light comes on when dc jack is inserted, but when power button is pressed this component becomes very hot and nothing more happens.
    It's located near the corner of the motherboard close to the ram socket and behind the power button.
    Close to it there's an ITE it8566vg (unknown) and a load switch DML3009LDC.

    So what is this JWFN 1rD9B ?
    Thanks in advance....

    A2681 M2 MacBook Air Dead Logic Board
    by yuuki47
    Hello...

    My sister purchased an M2 MacBook Air a year and a half ago. While she was using it a week ago, it randomly shut off and no longer powers on. There are no signs of life and not even the MagSafe indicator LED lights up.

    We took it to Apple and they disconnected the battery and tried a bunch of stuff before they declared the logic board "brain dead" and quoted us about £567 to replace it. Typical of them...

    eBay replacements run about £367 with the Touch ID sensor included.

    I did consider to probe the logic board for shorts...

    by sam_sam_sam
    I bought one of these and it works perfectly fine for my new iPhone SE version 3 with wireless charging which I was surprised that it works because of Apple's nonsense with non OEM charging devices that they will not work because of their proprietary nonsense

    HP ProDesk 600 G6 Mini BIOS unlocked - now EC can't find valid firmware
    by slavetothesound
    I Used a T48 and RCUnlocker to remove password from the BIOS on a previously fully functional HP ProDesk 600 G6 Mini. Everything went very smoothly and I was able to boot the machine and install an OS. I then unplugged the machine and put it on the shelf for a week.

    Now when I boot the machine, it does not POST. It plays 5.2 beep codes which are interpreted as:


    I read the firmware with the T48 and it is different than what I flashed to it, so I flashed the unlocked firmware that I had saved. No change. I could use some advice on next steps to take.
