Sometimes grinding out a welded chip is the only option, otherwise many layers can be ripped out. Unfortunately if the FR4 is carbonized in the area, there will be a short through layers which is rarely fixable at that point, need to excavate all the carbon with keeping the signal intact. Hate those.

I have encountered mosfet failures like this in automotive ECU/pcm's and Also an inverter Tig welder and if you carefully grind it away you can often reclaim it without pulling traces off but you need to pick your battles because it took a significant amount of amperage to cause that kind of damage which usually has a daisy chain effect and other components usually take on damage during the initial failure so from a business aspect it's not worth the time but from a project/hobby aspect go to town and try your best. It's not like you are going to destroy it any further but you can improve it and maybe save it.

And then, only if the device is irreplaceable and the customer has to have it regardless of the cost. Good call, thanks for the video showing the attempt.

Maybe that component was placed using an SMD adhesive, such as Structalit or Vitralit. We use adhesives to hold some components in place for reflow, and if we put them under a QFP or similar, no amount of heat will get it off...only the right debonding agent...and some of those will destroy the soldermask as well! That's why I prefer corner bonding...so repair people can SEE when it is there.

The moment any significant load was put on the device and the current risen it developed another short. So yeah... these are lost cause.

Constructive criticism: You just jumped straight to air gun and without flux for quite some time. Considering that it may be welded to the board, this should have been cleaned with proper chemicals first, then use some other flux that doesnt evaporate like yours, something like colophony. If it doesnt want to be removed with a little bit aggressive desoldering then it should be grinded. More effort we put into repair, more enjoyable and memorable it will be. This was chance to see video from nuclear bomb to full repair.

"from nuclear bomb to full repair", the layers of the PCB are full of carbon, effectively shorting them. The board needs to be escalated, and the layers replaced with wires (likely)... and then the mosfet is likely not the root issue, itself. If that was a personal laptop and just wanted to repair, it might worth the effort, doing as business doesn't feel anyhow right.

That is really sad. I dont think many manufacturers are adding proper short protection to these boards nowdays, like fast blow fuses and diodes on high current lines... There was probably nothing even wrong with that IC, but if there was a short after it in the circuit, that huge amount of current draw going through that chip could have fried it big time Like why did the charger not go into protection mode? Hp seems to be poor quality

Anything can be fixed. It's just a matter of the cost. For my laptops I have found used replacement boards on Ebay. Over the years I have been spending around $150.00 for every board I purchased since 2005. I recently upgraded my old former powerhouse to a new sleek type and went for the enhanced 2 year repair anything plan hoping that by the time it expired used parts will become available somewhere. For the most part I never purchase the extended warranties due to their excessive cost. They cost up to 20% of the purchase price for items with a low failure rate. Northridge rocks!.
