yeah it'd also help to have someone nearby just in case you start to drown on your own spit
Laptops are tricky to take apart. I had to replace my laptop keyboard on a Toshiba Satellite M-45 (trash, btw), which was a total bitch because the part above the keyboard you have to remove was extremely flimsy and was jam-packed with circuitry in such a way that if you didn't follow correct procedure in removing it your sound system was fucked or you'd just have a really ugly looking laptop. Not to mention the keyboard ribbon was too short so you had to replace the keyboard and slip the ribbon in blind. I digress. While opening the back up shouldn't be a problem, you should always exercise caution with something that expensive.
But if your comment was from past experience, then I feel for you man. It's okay to have problems.
