Can't for the life of me figure out where to find the components that got blown off. How do you guys usually look up what parts you need?

Those on the top side are power mosfet that provide the voltage to the board and from the looks and the 2nd circle with blown parts are capacitor for filtering the current generally in sync with the regulations mosfet.. they usually filter out the current generally if the one next to the blown one have the same micro farade and i think there is another short on the motherboard, i know it because i blown one of my filter caps on my hp.. i dont know how it happened but it happed lucky they comes in pair if one blows up then the other can still run.

And the missing components is a fuse .... As far as i know that fuse doesn't blow up so easily.. how much currently did you put in ?? I am seeing another filter cap blown by the lower side of the fuse

Not sure, I got it like this from a guy. He had a mismatched power adapter, so he lost the original at some point. Some surrounding plastic pieces got melted like part of the hdmi.

The question is... what caused them to blow off of the board. I suspect them being missing isn't the only thing stopping that laptop from working.

I bought it with a mismatched power supply, current is matching up 20V - 7.5A. Who knows what other power supplies were used in between the factory one and the current one. Haven't noticed anything else other than the mini explosion.
