Fried PWM Chip on Acer Motherboard

[armedtoe]

Laptop had broken hinge. LCD cable was left exposed. LCD Cable bent unnaturally, causing sparks and dodgy connection to lcd. Replaced LCD Cable & hinges. Black Screen.

This chip is broken. At first, I was dealing with only black screen (still booted up on external HDMI Monitor), now it won't start at all.

I believe it to be some sort of power management chip, but I can't find a HK2KD chip anywhere.

I'm fairly new into chip identification and replacement, so does anyone know where I can find a replacement?

The board is from a Acer Aspire V5-431.

People don't replace components they replace the whole board because, unless you have a surface mount oven and surface mount solder, it is very hard to do. Your best bet is to buy another broken laptop that is the same model as yours and replace the broken parts with the good ones that are in your laptop.
