  • Lenovo y50-70 la-b111p board burned pq302

    First of all hello! I'm happy that this forum exists and thanks to you all!
    This is my private laptop and I just want to fix it, because I broke it...

    Now to the problem:
    Lenovo y50-70 LA-B111P 1A board
    A few days ago I've changed thermal paste and thermal pads (K5 pro). With that I've shorted out PC1130 and/or PC1108

    On battery laptop works, but the power supply doesn't charge it. I've noticed that it's a PQ302 chip (it's burned). Also found that PL301 is cracked.

    What should I check and how (I only have a basic multimeter)

    Hello, I'm Bartosz (Poland).
    Found this forum because of my laptop, which fried because of me! I have very low skills in repairing tech, but lets give it a try! I love learning new things so welcome everybody.
