    Lenovo Yoga 300-11IBR problems

    Hi all,
    I have problems with this laptop. At first was completely dead. After ec bios flash laptop starts working. But keyboard and touchpad sometimes works fine and some time not. When it's not working FN keys are fully working only and other keys not also touchpad not working. And other problem is battery or charging. Sometimes battery has for instance 80% and windows says “Low battery”.. and power adapter is connected.
    I replace cmos battery because was discharged, flash latest bios from official page lenovo, I resolder all pins of KBC.
    I mean my kbc is the problem or? Im not one with similiar problems .. but I can' t find solution. Any idea or help please? Thanks

    Mobo is: BM5488 FPC V1.4

              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

              Now the PD controller always negotiates 5V @ 2A, even with known-good chargers
              🧠 What I’ve Done So Far
              Flashed...
