Water Damaged Laptop Repaired
Back in the day when I was teaching and training students in the field of TV broadcasting at a local college; one of my students who is now married and have kids came to my shop and asked me if I can take a look at her Laptop and see what was wrong with it.
This laptop has an internal battery and not external ones like normal laptops. So I took the screws off and right away, I disconnected the battery from the mother board and started looking for problem and I saw many of them, check this out.
That is the first thing that I saw when I took the back cover off. The water in this laptop dried already and that means; this water damage was not recent.
When I asked the customer, she explained it happened about one week ago. At that time, the laptop was up and running but when it shut down, she brought it for repair.
I took the board off and checked for more damage and look what I saw and this was not the end of this water damage issues.
The water damage was not all over the board but most of it. So I took my tooth brush and cleaning alcohol and started rubbing and cleaning as much as I could. I came across some bad areas and after I cleaned them, I re soldered some parts that were not making good connection with the joints on board.
I took off the heat sink of the main chip and checked the thermal paste there and it was ok. As I let the board dry and then I put everything back together, I powered on the Laptop and guess what?
It actually came on, but with two problems, one was the cooling fan making noises but after I lubricated it, it sounded much better but it needed replacement. Second problem was the keyboard; it was not working the way it should be.
I called the customer and I explained the situation and basically, they were happy with the results. I ordered a new fan and a key board and still waiting for them. At the mean time, I advised them to use an external key board till I get the new replacement,
