I was cleaning some sticky goo off of my case (I had a type of sticker on it) and I was using rubbing alcohol. Im not sure if this would affect the touchpad but I decided to take the casing apart as to not get the alcohol on the touchpad, although a tiny bit did get on it before I took the casing apart. when I put everything back together, (i've taken this laptop apart a million times to fix things) and when I turned the computer on, all of a sudden the touchpad didn't work, which doesn't make any sense since it was working fine!! Anyone have any thoughts, im getting quite frustraited with this!! Please help!
