    Lenovo ThinkPad Z13 JZ3A0 NM-E071 Rev.1 no power, usb-c stuck at 5 volts


    Looking for help.
    I have a Lenovo ThinkPad Z13 JZ3A0 NM-E071 Rev.1, charging stuck at 5 volts / 0.09A.
    According to the customer, he tried to replace the battery himself, and this is what happened.

    I suspect that one of the two USB-C controllers (U5401 OR 5301) has failed.
    Can anyone confirm that?

    Presented voltages on a board:
    (measured on coils)

    PL1901 - 3.3v,
    PL0501 - 3.3v
    PL0202 - 5.14v
    PL1601 - 1.8v
    PL1401 - 0.75v

    Any help appreciated.

      MacBook Pro 13inch 2017mid (A1706 820-00923-A) - liquid damage - USBC and Display short circuit
      by rilley
      Hello everyone,
      I am new into this, sorry to post it here. I want to make this as a pet hobby project, as this mac is not urgent.

      I have (Macbook Pro 13inch 2017mid) A1706 820-00923-A

      My mac had liquid damage a long time ago, the connector from J8500 is damaged on pin 46 (PP5V_S0_ALSCAM_F), I guess the LCD/display panel is in short circuit, as I saw the connector from the LCD burned as well.

      And the resistor L4004 is literally burned.

      From what I see from the schematics, it does not affect any other rails, only the connection to the display...

      usbc connector replacement on mobile
      by drscoot
      I replaced the broken usbc connector on this Ciontek CS50 mobile device. It worked fine afterwards, although it looks like the battery went down quickly and the device got warm at the back (battery section). After putting it in standby for a while it didn't came back anymore?
      The battery is still charging (red led), but no power on.
      I had another look at the usbc connector, it looks like one of the components is melted down (blue marking)? I have a picture of an untouched device and then the repaired device with 2 pictures; what are these components with B1 and PB marking? Are these...

      [Help] Lenovo Yoga Slim 7-14ARE05 (DA0LS3MBAF0) – 25Q80DVN1G Flash Is All FF, USB-C PD Stuck at 5V
      by ekozeko333
      Hi all,
      I’m trying to recover a Lenovo Yoga Slim 7-14ARE05 with board DA0LS3MBAF0 Rev:F. I’ve run into an unusual issue where USB-C PD is stuck at 4.7–5V and the system won’t boot (keyboard lights flash briefly, then nothing).
      🔥 The Problem Started After Suspected ESD/PD Fault
      I experienced a power issue or ESD event through a USB-C charger
      After that, the NX20P5090 power switch was visibly burned and was replaced
      Now the PD controller always negotiates 5V @ 2A, even with known-good chargers
      🧠 What I’ve Done So Far
      Flashed...
