Hi there, I am using MacBook. Yesterday, I cleaned the keyboard using some cleaning liquid. After that, some keys have not been working. For eg. 'H' key does not work. But if I press 'Y' key, 'H' gets executed. Similarly, other keys are behaving abnormally. What might be the reason.
Sounds like you introduced some shorts. Let the keyboard dry out thoroughly and see if it returns to normal.
It may, or it may not.
I had to replace my keyboard at work because of this. Though instead of cleaning fluid it was coffee!
I'm a klutz and am always spilling or sloshing coffee everywhere. All the books and papers on my desk are thoroughly coffee-stained. So I know enough to keep the cup away from the keyboard. But one day I elbowed the cup, and a perfect arc of coffee leapt about 2 feet and smack dab into the middle of the numeric keypad. 360 possible degrees to choose from, and it chose the direction of the keyboard.
The IT crew even disassembled the keyboard in an attempt at repair, but to no avail.
