    Motherboard component blown up - ASUS Q550LF

    Hello folks,

    Once I was removing the internal battery of my laptop and the screw driver accidentally dropped on the motherboard, there was a smoke and it looks like 2 capacitors have blown up.

    Since then I was using the laptop normally, but now, after a week more or less, my battery doesn't charge anymore and I have to use it constantly plugged to the AC.
    Furthermore at the same time a strange problem started to happen, once in a while the laptop suddenly goes to the sleep mode and it's for sure not software's configuration problem. I believe it's related also to the blown component.

    My guess (really just the idea that came to my mind) is that this component was a kind of voltage regulator, and at some point some higher voltage passed through and spoiled the battery.

    Do you guys have any guesses of what is this component and how could I fix it? Or if I could possibly buy this component somewhere? On the motherboard it seems to be written PJ8805 and PJ8806.



    Any tip is very welcome!

    Then actually look carbon graphite fuses and that looks like the battery connection next to it....

    Good chance the cause of not charging...

    Common problem on Dell's not charging is a cracked fuse, then easier to find if burned...

    Here is what they should look like..

    Very common and replaceable parts - if you have a scrap board
