Help with Corroded Board

[Redjack]

Good news: I got a lovely 81/110 for only $10!

Bad news: there were some "video" problems that turned out to be a leaked Backup Battery. The owner said it would work but just had the video problem...well now I know it maybe a bit harder than that. Any way to salvage the motherboard? I understand that it is essentially an 8100 tweaked by Radius. Just wondering what I can do to try and fix it or clean it, sounds like it was working beautifully until that mishap.

If you guys think I should go about cleaning, I'd like some details since I don't know the first thing about cleaning mobos...

Any ideas??

I am not sure what chemicals could be used topically, and I would avoid skin contact with any residue in any case. There is Lithium in the cell, and Lithium is a nasty substance.

I would maybe just wash well, lay out to dry well, reassemble & try your luck? I stand to be corrected, but I would be inclined to take a garden hose to it near a storm drain on the street in the first instance, on a gentle setting, followed by the shower or the dishwasher.

Logic boards are not hurt by water, though perhaps the quality of the water used may be an issue in some areas. The usual precautions re. static electricity do apply when washing, but they apply whether you use water, alcohol or any other chemical.

There are lots of threads about board washing here. A quick search should turn them up. That would be better than any advice I could offer myself.

Agreed with Bunsen. I did it with my Classic II logic board that had severe systemic corrosion and it worked quite well.

I found a warm, but not hot, water setting, using "softened" water, with no soap, set to only the rinse cycle, produced the best results.

Kewl, I was worried that corrosion from battery gunk was irreparable compared to "run of the mill" messes inside the board. I didn't realize that cleanup of battery-induced corrosion was not only doable but has been discussed! Thanks for the suggestion, will start searching now!

Well, it's only the first step, but cleaning off the chemicals is definitely the place to begin. Don't do it in a dishwasher, though - Lithium is nasty stuff.

A dishwasher should work fine. The corrosion from the battery has fully reacted with the components of the logic board and/or air so it should have formed stable compounds at this point. The only way it will react now is if you expose it to a strong oxidizing agent and if you have that in your water I'd be far more concerned about my internal organs at that point than the logic board.
