I was watching some youtube videos (laptop was plugged in) when it suddenly shut off with no sound, i tried to power it on a couple of times but it won't turn on, after 5 minutes i smell burning plastic and quickly removed the charger. Laptop never went past 70 degrees and i've been using it fine up until this point, i bought it last month.

    The charger PSU is from Delta Electronics, so it is of the highest quality and is very unlikely to be at fault. I don't think there are any liquid electrolytic capacitors in this laptop, and the solid polymer capacitors should not cause this. The battery is from a relatively low grade manufacturer, LG Chem, but this particular model doesn't appear to have many issues with batteries, as it isn't a thin and light model.

    It could be the SSD tremendously overheated to the point of forcefully shutting down. Even if the CPU never exceeded 70 C, the SSD in this model can reach 90 C under load, which is enough to melt plastic, even if the battery, capacitors, and charger are fine. An upgrade to 2.5" SSD, or better yet HDD, is the solution, but unfortunately this model only supports M.2 sticks.

    @Dauniverse if the laptop still have warranty, get it fixed immediately or go to a shop that is specialized in motherboard repair.
    Please remember to include @AnhEZ28 when you want to reply back to my comment so that I can check your response.

    Thank you for your answer! I really didn't know that even SSDs can heat up, even a m.2 stick for that matter. Shouldn't the laptop still bootup if its just an SSD failure? Or did it fry my motherboard too?
