some keys on my keyboard will not work
I was going to sell my MacBook so i decided to clean it with rubbing alcohol (ive done this pently of times b4 mind you). nothing was wrong with it for a couple few days. buyer back down on me so i decided to keep my mac, now some of the keys wont work on me!(the a-l, and the z-m keys) Its definitely not a software issue because I formatted my MacBook, so its hardware.
I have no idea what to do, HELP! :[
I think you probably used too much liquid when cleaning the keys and part of the liquid went inside the keyboard internal layers dissolving the electrical circuit (traces) that conducts the keyboard key signal to the processor. Unfortunately since the keyboard can't be swapped on a MacBook you'll have to replace the MB top case.
