Hello I received my macbookpro(15) two years ago. Its on Leopard atm, but I want to upgradr. Problem is I'm having lots of problems I'd like to fix first. The first thing that happened was that I dropped my macbook. It got a dent near the charge port and now the first USB port does not work. That didn't ever bother me much so I ignored it. Later on, I spilled Dr. Pepper all over the keyboard ( I believe that hurts my warranty ) and it wouldn't turn on so I left it open, upside down overnight and it worked fine the next day so I didn't look any further into it. At some point I woke up to ym trackpad click not working so I had to change it to tap. Well recently the keys ZXCVBNM<> stopped working out of no where so I have to use the keyboard viewer to type those. I have all these problems that I have no idea where they came from or how to fix them. Please help me.
