I always take my technical things to Mike, at A Laptop Shoppe. I guess he learned electronics repair in the Air Force.
When my 4 year old so poured a milk shake down the top vents of my brand new (powered on) monitor, I took it to Mike. He fixed it. When my wife (accidentally) poured soup on my laptop (left it on the kitchen table), I took it to Mike. He fixed it.
When my latest laptop was overheating, I took it to Mike. He fixed it. I just took a keyboard/synthesizer to Mike, to fix a dead key. He fixed it.
He knows what he is doing.
