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

06-08-2025, 02:56 PM

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...

[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...

MacBook Air A2337 - 820-02016 - Stuck at 5v - Varying current draw - Board had short

by duwane

Hi All.

I have an 820-02016 board (A2337 M1) that has come in for data recovery. Reported as liquid damage, but no visible evidence of any liquid damage.

Board was initially stuck at 5v, and current only spiking occasionally to around 400mA and cycling.

After initial troubleshooting, found that C7800 (which feeds the power rail PP5V_BSTLQ_VOUT_SPMU) was dead short to ground.

Replaced C7800 and short gone. Board still stuck at 5v. Current draw behaviour changed. It now spikes up for a second to around 100mA to 130mA, then drops down to...
