Probably a temporary fix.
I was told something about soot being acidic or whatever and the dread enemy of electronics.
That’s why the adjuster told to me claim everything, even if it seems to be working now.
A month or six from now all of it might crap out.
Said he’d seen happen a lot.
That laptop was on the bottom floor with a hundred feet, two rooms and a door between it and the fire but it got messed up anyway.
All my electronic stuff was in the living room and was probably affected too.
God have mercy on me, I feel so beaten down.
Everything I loved is gone…or going.
It’s too much.
Soot is carbon particles, which is electrically conductive, just like tiny metal shavings.
Resistors used to be made of carbon, but now are made of more stable materials, like metal oxide or carbon film.
Soot all over the PC board is like throwing a handful of powdered metal onto it. It’s a wonder it didn’t catch fire.
Blowing it out with an air hose probably got most of the stuff out, but a soft bristle brush, like a paint brush, in addition to air blast would have been more effective.
I used to work for Tektronix field service and when we got in oscilloscopes from the field for repair, they were usually filthy.
The first thing I would do is WASH THEM INSIDE AND OUT WITH SOAP AND WATER.
That’s right soap and hot water!
And a brush!
After a thorough rinsing with clear water, blowing out all the excess water with an air hose, I’d put it in a oven overnight at 130°F so it would be thoroughly dry the next morning.
Never had a problem that was caused by dirt or other contaminates......................
