windows + flash warning
-
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

In a Beelink GTR mini PC, mine has an Intel AX200NGW WLAN module.
Tried (only with keyboard/mouse connected):- BIOS + database update
- Using latest Windows 11 image built with official image creation tool
- Previous setup version for Windows 11 installer
- Replacing SSD without a slow block (the previous SSD had a slow block with access time > 500 mS)
- TPM reset (worked to the point where DRIVER_PNP_WATCHDOG error message is displayed briefly after the point of stalling)
- Disabling power to WLAN and LAN modules in BIOS (Advanced > AMD PBS > PCI Express Configuration)

Hello, I'm stuck in troubleshooting…
The flash system works like that : when the (mechanic) flash button is pressed, the flash mecanically pop up, and a circuit buck boost elevate 7v (batt) to 200-300v (?) for charging the big capacitor. And when the photo shoot button is pressed, the capacitor is discharged in the xeon light.
In the D800, there is a first « power board » close to the battery. 2 wires (batt 7v) goes to another little « flash board ». I measured 7v, so ok.
When I press the flash button, it's detected by the system, flash icon appear on LDC display.... -
