    To confirm, this is the 2nd USB port in your testing? From the article on how 20V is selected, all CD321x ACE (power delivery) controllers must be operational to allow for the 20 volts to be selected.

    reference reading:

    CD3215 Bootup Sequence - LogiWiki​
    thank you with that reference im checking

        Lowest possible resistance on laptop motherboard rail - Guide Table request
        by Nagy Daniel
        Hi, I'm Daniel, and I'm new to the world of repairing motherboards.

        I would like to create a table, or more likely a guideline about the voltage rails and their possible resistance rail.

        I know that the motherboard design has a very big depend on the rail's resistance, but I would like to know what is the smallest value for a rail that can be acceptable. For example, I heard that some new gaming motherboards can have 0,5 Ohm resistance on the GPU rail, but on an older type, it could be a sign of a shorted GPU rail.

        So, I generated a table with AI so I can...

        General question about MacBook power rails for repair.
        by SarcasticOP
        I am looking at an A2337 and found this for the order of power rails and what they do. Can this be confirmed before I dive into hunting down power rails that do not exist or are not neccisary?
        • PPBUS_G3H (12.6V-12.8V)
          • This is the main power rail that supplies power to the entire system. Check this rail first, as it must be present for other power rails to work.
        • PP3V42_G3H (3.42V)
          • This power rail is derived from PPBUS_G3H and is used to power the SMC (System Management Controller) and other essential circuits. It should be present if PPBUS_G3H is working correctly.
        • PPVRTC_G3H (3.3V)

        Apple MacBook Pro A2338 820-02773-A AON Rail burnt
        by mferna14
        Hi Dear Friend., I am working on a Apple MacBook Pro A2338 820-02773-A. The history was that the AON Rail on the Trackpad connector JT400 was burnt. After I removed the burnt connector, I tested with the meter & no shorts. Connected the USB C power & all booted fine, no problems at all. I soldered a New TP connector put in the old trackpad with a brand new Flex cable. The laptop beeped in the start but no display. I removed the connector & the display was fine again. USED a known good Trackpad & a Flex cable, even with this still the same problem. I checked the connector whether...

        MacBook Pro 2018 with Activation Lock
        by envym
        Hi everyone!

        I have a 2018 MacBook Pro (with Sequoia OS) that I've been using for years with no problem. I recently received an M2 MacBook Pro so I'm mostly using it and not the 2018 one, but since a friend of mine needs a computer, I thought I could restore my 2018 and give it brand-new-like to my friend.

        I tried using the built-in tool to restore the MacBook (Settings > General > Transfer or restore > Delete) but it got stuck when trying to remove the Find Device configuration (it asked me for the password for my old Apple ID -now I use the same account but...

        MacBook Air A1466 820-00165-A 5V Rail Pulses (on & off)
        by junda
        hi, i also have the same (P5V_S4RS3) MacBook Air A1466 820-00165-A 5V Rail Pulses (on & off) The strange thing is when I kept machine for 1 day and connect the power It powers on with Chime and booots half way with Apple logo and stuck. at that time when I power of and try power up Fan spins for few seconds and goes off with no P5V_S4RS3 and also the P5V_S4RS3 EN pulses on and off with 3,24 V.
