    Just FYI, that's a 3.3V chip:

        Absolute maximum is 4.6V. It could just be that the chip behaves unreliably at this voltage.

          Ok, confirmed the chip is good, no hard from 5v.
          Main issue moved on laptop repair section https://www.badcaps.net/forum/troubl...ton-is-pressed

          Thank you for answering!

            Thinkpad t480s, completely dead after BIOS flash using CH341A programmer
            by what_1282105
            Following this guide (https://www.reddit.com/r/thinkpad/co...g_and_flashing) i re-flashed my t480s BIOS using an external (CH341A) programmer. The flash didnt work, so i reverted back to my BIOS backup successfully. The BIOS in the chip and the BIOS backup file are identical according to windows' file compare. The revert, however, didnt work: the only thing the computer does is flash the power button 3 times when AC power is connected. I've tried unplugging the CMOS battery, holding the reset button and holding down the power button- no signs of life....

            Nikon D800 camera - flash don’t work and capacitor don’t charge
            by corrize
            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....

            [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

            ASRock N100M, no picture no boot, but semi-alive
            by Exim
            Hi guys,
            I managed to semi-kill an ASRock N100M board after updating Bios from 1.10 to 2.01. It's a zombie now, dead, but not dead.

            ASRock N100M special features:
            - CPU soldered to board, small Intel 12th gen
            - iGPU
            - four POST LEDs

            Problem after updating Bios to 2.01 using the in-Bios update tool: no picture, no boot.
            I am not sure anymore if it booted at least once successfully after updating the bios to 2.01, maybe not, I can't remember. I think it did not.

            Symptoms:
            - no picture/signal on any of the display connectors,...

            Dell Optiplex 7490 AIO - red power led after flash
            by Mark01
            Hi guys,

            This is my first post! 🚀
            I have no idea what I’m doing, but I’m learning by trial and error.

            I’m currently working on a Dell Optiplex AIO 7490—one of a bunch of AIOs that mysteriously failed to POST just a few days after the warranty expired. The original issue was that the PC worked fine until it was rebooted, after which it got stuck on a black screen (no backlight), with fans spinning at normal speed and a solid white power LED. Forcing it off by holding the power button would just cause it to switch on automatically and get stuck again on...
