I had some issues with steps 21, 22 and 23 ... the tabs would rip off. After the third one I used the plastic card to gently create some space for the strip to escape.
Have you actually done the replacement? It's actually pretty easy. Apple did everything they could to make it as painless as possible: the old adhesive separates without *any* residue, it doesn't rip apart, it doesn't make a mess. Things align like magic.
True, it could be easier. Like with the old color iMac SD. But since I don't take my iMac apart every day, doing this once or maybe twice in my computer's lifetime is a small price to pay for a *really* slim and good looking device.
Good input. I just ordered the strips to swap my HD with a SSD. I've tested i via USB but it keeps getting corrupted, second SSD too and people say it's the fact that I'm running it via USB. So now I'm ready for the big step and actually taking apart my iMac :)
Tape seems like an excellent idea. What's that silvery tape you used?
Since my original battery was bloated I was terrified of it. So I put on my helmet and motorcycle gloves but still managed to get it out with the plastic tab and some pliers :)
Now the "problem" with the new battery is that it charged from 1% to 100 in less than an hour (attached to my MBP), and hast lost 11% in the last hour or so. Does the new battery need some kind of breaking-in?
