Alright I'm going to tear into the old girl one last time.

Going for full submersion 91% alcohol soak followed by alcohol rinse.

How long should I let this 'marinade'?

Good luck however you clean it! My only concern with using hot water is potentially warping the motherboard, plus the fact that water can take hours to dry off in air from all the nooks and crannies, if you don't have a blowdryer that blows cool air.

EDIT:

My adventure with a spilled liquid + a laptop!

My Logitech keyboard got soaked in Gatorade. So, i soaked it. After ot dried, When I pushed the k key, the pound,⛎⛎♓⏰♈♏♋ among others would show up. And it kept going ♑♑♑♑♑ when I let go of the K. So... Put it away for a couple weeks while I used a $10 keyboard. Now, it works perfect!! So.... Let it set. Not like the value is dropping much

The motherboard is out and submerged (mostly) in alcohol.

Look at this:



This is what I believe to be the northbridge of the chipset. Notice the discoloration to the left and top of the chip itself (circled in red). Does anyone know what we're seeing there? Wondering if those are burns?

It is indeed the "northbridge", or PCH as they're calling it now. an HM67 chipset. http://ark.intel.com/products/52809/Intel-BD82HM67-PCH

I don't know what that discolouration is....it could well be heat damage, though burns tend to be darker in colour.....though i suppose it could get lighter too. Without comparison to another HM67 chip, its hard to tell.

AAAnnnnndddddd looking at the pics of other HM67 chips, it looks like they have that same "discolouration" so it'll just be part of the etch mask pattern. Should be ok. smile.gif

Let it dry overnight and fire it up is my vote.

You are 100% correct. Just did a little Googling and sure enough those marks appear in stock photos of the H67 chip. Thanks! thumb.gif

I added an edit to post #66, I feel it's important to mention to any who may have missed it.

TL;DL version: DO NOT HEAT ALCOHOL wink.gif
