I’ve got a laptop that burned the first MOSFET on the 19vdc power input. Can’t find a cross, this 5 pin configuration is different than what I’m used to. Please provide any help you can on identifying it.

Opps 6 pin chip…

Looks to have a ground under the backside

What you have is likely obsolete part number: AON7403

I present for your consideration potential alternative part number DMP3021SFVWQ-13
