    A2141 820-01700 - 5v / .454a all four ports

    Just power supply coils, or every single coil on the board? That's maybe hundreds, so I'm assuming you mean just the power supply coils. Can you confirm?

    A2141 820-01700 - 5v / .454a all four ports

    This is with battery now disconnected, since this item is on the back side of the board. R7900 has constant 3.38v on both sides.

    It was with the battery and charger connected. I don't think I have another adapter. This is the one I always use. I'll order one and touch base again when it arrives and I test.

    OK, none are stable. Some have 0-.8v fluctuations and others have 0-1.1v fluctuations.

    I'm looking up SLPS2R and AWAKE in the boardview but there are many. Can you tell me a preferable measurement point? This device does not show up in Apple Configurator.

    Hey! Thanks for the response! No history available unfortunately. Although my customers tend to purposely leave out details it seems. I am using an OEM 100W apple USBc power adapter for reference. With F7000/1 removed, I am getting 12.32v @ C7050.

    Have a A2141 no power complaint. Board is out, I'm measuring 5v, .454a draw on all four ports. Voltage @ F700 jumps between 7.87v and 8.77v. What can I check next?
