Asus GL551JM power short after water damage

[Learn2Day]

Hi guys,

Need your help with this laptop. It got water damage. Even after cleaning it's quite noticeable on the photo.
I noticed the charger would turn on protection as soon as I plugged it in, so I injected power and right away noticed that the BQ735 from TI heats up pretty fast. Probably needs replacement. But I'd like to try using flux and reflow water damaged components before anything else..

My question is, considering this is a fairly recent laptop and I don't to further damage the board, what hot air temp do you recommend? I usually use 350ºC but I'm afraid it might be too hot..

Thanks.

I have my hot air on 380°C, the temperature on the display does not really matter as its how close you have the nozzle that matters.
Lead free melts at about 220°C.

Hey guys,
Thanks for the tips, I already ruled out the 735, but even after removing it problem's still there, but now I have other components heating up, highlighted in photo..

I'm pretty sure this some component that goes into short as soon as power is injected, however there's not short without power.. I'm lost!

Any tips on where to go next?

Thanks.

What's a PQ?

PQ, usually is the IC description on the board..

Will it help if I send a mobo photo and highlight where the water residues were?

Thanks again.
