In this article I show how I recovered a MacBook pro A1278 which has been spilled acetone. It is not the first time I fixed a MacBook in which the liquid is finished: in the past I have had a car that was over a glass of wine …
Apple MacBook Pro A1278
Half A Bottle Of Acetone Over The Keyboard Of The MacBook Pro
The MacBook In This Case Does Not Start Even
I Have Attempted An Approach Of Cleaning With Isopropyl Alcohol And Spray Dry Contacts For Both The Logic Board That For The Keyboard.
After having completely disassembled the MacBook Pro, pulling both the logic board that the rest (a detailed article on a ‘ service to a Apple MacBook Pro A1278 , can be found here ) we can dwell on the keyboard.
I say just one thing that can make you give up: the attempt to recover a keyboard that has been damaged by liquid is really a question mark .
In fact, the key contacts are copper that are damaged as soon as there is some external element, making futile attempts to recover: however, if you have time you can still try to clean it with a special solution (isopropyl alcohol for example). To me it went well …
Initially I tried using a cotton bud soaked in alcohol and to add below the first layer of plastic …
..then I realized it was a waste of time. So I began to disassemble the keyboard. I removed the first layer containing the LEDs of the backlight, then I continued ..
… But not happy I wanted to remove the other layers. To do so, armed with patience, I unscrewed all the many small screws (they are so many, many …) and I disassembled the whole thing.
Careful not to lose the small screws … after we reassemble everything as it is!
Usually on these MacBook power button is connected to the keyboard, we must then unscrew the two small screws that secure with a metal plate on the button to the body.
Now we can gently lift the keyboard by removing it from the body.
Now we groped queit: spray dry contacts, isopropyl alcohol and a lot of patience.
Let the keyboard dry for VERY, VERY, VERY time and avoid completely the use of any heat source (hairdryer, etc.) because in this way we will certainly a boost to the trash bin.
Remount the keyboard, making sure to put everything back as it was ..
Now it’s up to the logic board. I expect this in such cases two procedures:
– Removal of all parties (heat sinks, cables, etc.);
– Dry the entire board using isopropyl alcohol, spray for dry contacts; Using brush ‘clean’ to be passed on the card still damp solution;
– Careful analysis of possible points objects oxidation (usually colored green): these must act with greater intensity, even with help of a cotton handmade t;
– Drying of the logic board also through plate pre-heat to 100-140 degrees.
After work I get on the board and do a first firing test, taking the flat keyboard detached and possibly using the alternative pad to start it .
Result: lights !!! Thank goodness … already something … now let’s see if they work power button and keyboard …
Allright !! I restored brilliantly this MacBook Pro! Of course the keyboard much ‘ass’ and I’ve lost a bit of time … but it was worth it !!
