Acer Aspire E1-531 Keyboard Not Working Repaired
Today a customer sent to me his Acer Aspire E1-531 laptop with keyboard problem. The problem was his kid splash a glass of juice over the keyboard. After a day or two the keyboard stops working. After my inspection, I could feel that sticky feeling of the juice.
Therefore, I decide to take out the keyboard and try to wash it. See the picture how to remove the keyboard, it is pretty simple. You need a screwdriver and bit of patience…
This is the Acer Aspire E1-531
Put the screwdriver gently and unlock all around the keyboard.
Lift the keyboard but take care of the flat cable under the keyboard.
I then splashed the keyboard with mix of demineralized (distilled) water and soap-see the photo below:
The reason why I use demineralized water for washing electronic pcb or so is because that type of water have less ions and so it did not conduct electricity compared to tap water.
After the washing, I took out the moisture protective foil from the keyboard and dry it with a hair dryer, sun, or whatever. This protective foil protects the inner side of the laptop from entering minimal amount fluid drops. If you leave on until you dry the keyboard you will get steam under the foil and your keyboard won’t be dry.
After this surgery, I reassembled and tested the keyboard and it was working fine.
