Water damaged Motherbaord? help?

February 12, 2018 at 05:39:27
Specs: iPhone
I have an Asus maximums viii ranger that has a streak of liquid running down it, it is noticeable. The psu and the cpu cooler fans spin but nothing else spins. I should also add that I spilt Budweiser on it later this morning (that’s how this happened):(

Any idea? I can post picture too but idk how.

Thank you,

oh dear... Anything other than water uusally is pain to deal... Fruit juices, alchohol (beer especially) invariably leave a sticky residue after they appear to have dried

As this is a motherboard that can be removed (if I found the correct one via google), I suggest you do - carefully.

Wash it with distilled water - at lest filtered if no distilled available.

Wrap in paper towel and blot it gently afterwards - NOT HOT - environment; typically an airing cupboard?

Leave it there for a few hours (overnight?) and then check to see it is dry... Presuming so there's a good chance till be OK to re-install and power up. Do NOT apply power until you have cleaned it and so on...

You could also blow dry the board with a hair dryer on cool-waml setting and held at a distance. Do not blast the board at close range - again after washing as above.

Do not use detergents when washing the board.

Occasionally can follow the water with something like ios-propyl alchohol as that will absorb some of the residual moisture from the water was. Then again blow dry and/or leave as above in a warm environment.

All of the above have been used successfully more than once in studios where have worked in the past; and the liquids ranged from tea, coffee, carrot soup, tomato soup; fruit juice... Some going into expensive and not easily replaced keyboards, and some into computerised control equipment (lighting desks and vision-mixers/switchers).

It might be safe to gently use a very soft toothbrush.
My experience is that rinsing with lukewarm water alone rarely
removes crud without agitation. But there is a lot of stuff on a
motherboard that can be destroyed by scrubbing.

Also, I think the reason trvlr says not to hold a dryer too
close to the board is to avoid heating it too much. On a setting
without heat you should be able to get close. Same with canned
compressed air. To blow water off an entire motherboard that
has been completely wetted, you may need an entire can.

If the humidity is low, or if you use isopropyl alcohol, a few
hours to dry should be enough, but otherwise I'd give it at
least 12 hours.

Thinking more re detergent. You could use mild/weak solution for the wash - but use an organic rather than chemically based. And ensure it is a weak sutipn (ideally still using with distilled water).

Use a very soft brush if needs be; possibly a very soft tooth brush, or a firm but not hard small paint brush - be that artists or decorators. Avoid serious scrubbing for the reasons “Jeff” has mentioned.

No need for quotes around my name since it is my real name. :-)

When I put a name in quotes - " " - it's to give the person whose suggestion/input to which I have referred due credit.

Don't always do it of course; depends on whether or not my grey cells are fully engaged... But it's intended as a compliment; credit where credit's due...

And we all know your real name isn't "Jeff" - it's Cuthebert; and you're the rightful heir to the throne of Ruritania - not that upstart Stewart Granger...

Not "Cuthelbert"? I use my real name so seldom, I forget how
to spell it.

I've seen people use quotes as a way to highlight something.
I often use *asterisks* for that purpose. I thought that might
be what you were doing, but decided to try to impose my own
standards because, you know, it's the Internet. I have used
quotes when the name was fake. But one time I used quotes
around the name "Sasha", thinking it was a nickname, only to
slowly get that it was the person's actual name. So I dunno,
you know?

Beer, eh?

I'll drop the "kwotes" then when I refer to you...

Asterix is usually used (at least in UK English/syntax - and possibly in Canada too) in a single form to attract attention to a foot note, or a reference earlier (or later) in the text. If more than one reference using an asterix, as in a second or more reference then they are shown as ** and *** and so on...

Incidentally Cuthelbert was, and remains, an imposter... He was the master mind behind the plot to give the throne to Stewart Granger...; believing that later he (Cuthelbert) would take over and give Granger the boot... But of course it never happened... Be careful you don't get mistaken for him...

At which point I'll plug my gray cells into the charging unit and go to bed...

RE #8; water, place it in a container & cover it with rice, leave it overnight on a radiator.

The dry rice trick works well - a cheap alternative to silica gel. But wrap the rice on a tissue or three or place on container with the motherboard- so as to avoid getting it (it’s dust) all over the motherboard

But first wash the board and dry with paper towel (as earlier suggested) to remove bulk of moisture.

The rice/silica gel is to extract residual moisture which may remain after the paper towel dry off; often under components.

There used to be a guy who posted regularly about washing motherboards. I think he said he put them in a dishwasher? He called himself "Dave the Snakes". He had a knack for starting some lively debates with his outlandish ideas & comments. It appears his account is still active but all his posts have been deleted.


Anyhow, I was given an old tower that was completely dust clogged & remembering his old posts, I figured I'd give it a shot. I didn't use a dishwasher but I soaked the board in a laundry tub & washed it with dish soap & a soft brush. I blew it off with my compressor & then let it air day for several days before testing it. It worked perfectly. Maybe Dave wasn't so wacky after all?

The key items to cautious about are any detergents used - none that might interact with board substrate or components; ensuring all detergent is fully rinsed away with (preferably soft or demineralised or distilled) water. And then left to dry in a warm environment after removing the obvious watery traces...

I know my chums at work more than once stripped down some computerised kit (which had been doused with soup or coke or tea/coffee) and washed the cards/boards in the sink with a very mild/weak detergent solution. And hard and expensive to replace complex keyboard several times were rescued the same way.

So Dave wasn’t too far out in left field... I wouldn’t wash a psu or drive system only you; only the motherboard and cards...
