Opened one of mine over a week ago... the whole dead battery issue... and now awaiting the new battery to arrived, so it sits opened on my desks next to me.
It was NOT easy as I found that the info online is still not very clear on some things, BUT after a good 1/2 hour, I manage to do it and not a single broken clip (but a couple of broken tabs that helps hold the clips in place, but from what I can see, not that important.
There's seven clips I think and are on three sides only... the side where the speakers are, there are no clips, but slots that once you get the clips "popped", the screen will open like a book to release the screen and back BUT, carefully, there's the cables that you must disconnect to move forward.
Then there's a bunch of screws all over the place with some mini-boards that needs to be removed before you can get to the motherboard, and then the battery...
And the gaskets are around the screen where you need to pry to pop the clips... and I didn't damage it at all as far as I can see/tell. I slid the letter opener very gently, prying it slowly popping the clip, and then placing a screwdriver in to hold it open while I moved on to the next clip.
Just use proper tools and be careful (and take all the time you need) and you should be fine I would think.
It's a really annoying design, and made to make the battery hard to get to (the plug/connector).. a few minor tweaks and they could have easily made the battery accessible from the back and removable/replaceable.
My tools were a staple remover and small screwdrivers (jewelers type) and lots of patience.
Go find an online guide with pictures and note where the clips are... if you pop those out by knowing their location, it'll be much easier...
Now that I've done it oce, I'd probably be able to do it in half the time easily.
I haven't put it back together yet, but once I get that battery in, I will be... and from what I see and can tell, I don't have any worries about it holding together... the worse will be to get all the parts reconnected, and will make sure that it's working before I close it.
But expect a LOT of small screws and lots of connection cables/ribbons that you have to unplug properly...
Replugging those ribbon cables is my biggest worry when I'll be putting it together again.
