    Hello guys,

    Lenovo V15-IIL M/B GS44D/GS54D NM-C71 Rev 1.0
    Customer say that this laptop died righe after connecting an cheap aftermarket PSU.

    Some readings:
    - VIN = 20V
    - PQ100 pin1-3 = 0
    - PQ100 pin4 = 0
    - PQ100 pin5 = 20V
    - V9B+ [PR100 pin4] = 0
    - +3VALW [RI4509 pin2] = 0
    - +5VALW [UI4302 pin5] = 0
    - +3VALW_PCH [DC701 pin2] = 0
    - +1.8VALW [RX4601 pin1] = 0
    - +VCCIN_AUX [PL9801 pin2] = 0
    - ACDRV [PR105 pin2] = 0

    Just removed PQ101: source & drain are shorted.

      Fixed: replaced PQ101 with AON7410 and the laptop is booting normally.

        Lenovo ideapad 330ICH - Dead, no volts on coils
        by Nagyesz
        Hi everyone, I replaced this motherboard because it was important to get it working, but it's been with me for a very long time. Now I finally have time to figure out what the problem is,
        I've never encountered something like this before;

        Lenovo T14 nm-c931 1th gen intel 10th DEAD
        by Zmay2509
        Hi, I have dead t14 gen1 with nm-c931 motherboard.

        Laptop doesn't turn on and does not show any sings of life.(battery is completely flat, do I need it for power on??)

        When I connect usb c power adapter it draws 0.02A at 20v, I get voltage 20.5V up to 2nd mosfet and nothing out (PQ0006 before current resistor and buck-boost) when I touch gate pin of PQ0006 with tweezers it opens and I get 20.5v on current resistor;
        But even with that "trick" I cant get laptop to turn on, that's probably because BQ25700ARSNR is not happy and not making VSYS15 rail.

        Lenovo Ideapad S130 is the CPU dead?
        by madan1
        Good day.
        I'm trying to figure out what's wrong with a Lenovo Ideapad S130 motherboard. When I connect it to the bench PSU and limit the supply to ~2.2A (about the limit of the lenovo stock PSU), the board absorbs all the amperage and the voltage on the PSU drops down to about 4-5V.
        The components on the board that get hot are the two mosfets ( 1 and 2 on the photo ) and the CPU. The resistance to ground measured on the power rail coils can be seen on the image (~17 and ~50 ohms). On the top of the CPU there are few caps which measure dead short. I checked all caps on the top side...

        Lenovo NM-A921 (Yoga 900-13ISK2) dead
        by reformatt
        This machine has been in a few times with an intermittent fault of not charging. Motherboard is NM-A921 (https://www.badcaps.net/filedata/fetch?id=2051581)

        So back again now, not working at all. Previously the adaptor had been replaced along with the DC charge port. This is one of these trapezoid shaped orange USB ports that Lenovo were using prior to going USB-C. It has 4 pins, but the DC connector jack on the PCB has 5 pins.

        Fault presentation was the adaptor is only producing 5.2V, not 20V and this isn't reaching the input of the NVDC charger (PQ5/PQ6). There are 5...

        - i have 3v3, 5v, 1v and others voltage. power botton drops to 0 and back 3v3.
